Glacier / Mytouch 4g ?

is it possible for Glacier / Mytouch 4g with CyanogenMod 7.1 (2.3.7)+ to be supported?

I thought I saw in change log of 7.1 saying it supports usb host???

I bought the usb host cable, wonder if thats all ill need if I need to make another cable I can solder and test it, in fact I bought the app and have proper Canon DSLR to test :)

currently im running CM 7.1 with Kernel (2.635.13-cm7-faux123-1.07-BFS+)

without any success :(

Does the Elf/ICS give you notification on the bottom saying that the camera is connected, and it launches the app? I have an Aurora, running 4.0.1 and I cannot get the Remote Release app to recognise my Canon 60D. Is there a setting I am missing somewhere. Super USer has enabled the app, and I using the OTG cable that came with the tablet. Any help would be appreciated.

Thanks!

Feature Requests

Chainfire,

Feature Requests (2):

#1 Please change or add option to use the “Live View” (The one with the photo details) Image review screen as the default after shot review when using Image review (+ follow shot).

Let me explain:

I do a lot of event shooting and I offer a portrait session. These are very fast paced, sometimes 80 -100 “models’ shots in an hour.

I predominately shoot handheld and do not use DLSRC to trigger photos. I prefer to shoot in Image review (+ follow shot).

My assistant / art director actually holds the tablet on a long cable. This way, he can review the images as well (I can see them on the lcd) and then quickly review them with the “model”

He then notes the image number on their registration form for easy name/image cross reference in post.

Currently, he has to change out of Image review (+ follow shot) and switch to Image review after each shot to get/ verify photo data. This, in the scheme of things, is obviously very time consuming.

Although, I would prefer the above method because it also gives access to the histogram, If this is not possible, could you at least add the option to view the Image Name overlayed on the Image review (+ follow shot) Image review.

#2 Add 1-3 custom menu item buttons or give the option to customize what 1,2,3 or all buttons on the main Live View screen.

Let me explain:

The 2 features I use the most are:

Image review (+ follow shot)

HDR

Although, accessing the options from the bottom right button is not difficult, it is always nice to have the features you use the most quickly accessible.

As I shoot in RAW, I personally do not use or often change: Picture style, Color temperature, Auto-lighting optimizer.

For me, these are better suited to be buried in a submenu or at least all on one submenu button.

Thank you for considering these changes.

I guess I'm not picking up on some nuances of operation. I have only checked basic operation (it does work) between my Thrive on 3.2 and 5D2. I just spent some time trying to figure the app out more and hit a wall. Especially in Av mode, I can set ISO and aperture but the display never changes. I am in a semi-dark room but cranking up the ISO to 6400 still doesn't give me any display difference. I can switch between f4.0 and f22 and see no change whatsoever. In Tv mode, there appears to be a limit that is hit when reducing exposure such that any additional decrease in exposure is not seen. Any shutter speed faster than 1/13s makes no difference. Images taken show that it's not just the display - it's the image, too.

What am I missing?

Edit: Just tried my Samsung Galaxy Nexus with 4.02 and had similar but somewhat different results (the exact exposure value changed but the same basic issue occurred). Also, when disconnecting the cable from the phone, DC remained running, consuming perhaps 3/4 CPU. Astro's task killer didn't work but Android's Apps killed it with the Force Close.

3 questions (sorry if they've been answered, hard to go through 127 pages);

1. Works with Nexus S?

2. Maybe link instructions on first page of how to make USB cable? Just a mini usb B to B?

3. I have a 550D that gives persistent error 70 on startup, I suspect if I could reset the settings to factory it would help, but it's impossible to do it before err 70 appears. (tried removing both batteries and dismantling the camera, still retains settings [I know because it has green colour scheme]) - Bit off topic but you think this software may be able to help some way?

Thanks! sent a link to all my photographer friends.

Hi,

All I did was I ran the market script, and after downloading the app I did the following steps:

1. Tablet on

2. Otg cable to tablet + connect that to the Usb cable that came with the 600d (i've tried others as well, some work some don't, but this does) and connect that to the camera.

3. fire up the camera and press the shutter button once.

4. open up dslr controller, should fire up.

You might have to repeat steps 3 & 4 a few times, haven't really got the hang of it yet why that is required sometimes....

After it fires up though it works like a dream...
[Paid Software Announcement and Discussion] Engelhuber:
Hi there. First of all i have to say thank you for this great app!

I'm trying to use it with my SGS and a 500D.

I'm on Onecomics RC3.1 with a modded kernel which enables OTG-Host mode.

There is an app called "USB Host Controller" where you can configure the settings and see which USB devices are connected.

The app tells me that there is a Canon Cam connected, but when i try to open the DSLR Controller it tells me that it couldn't find any compatible camera :(

Does anyone have experience with the SGS, DSLR Controller and the 500D?

The 500D is listed in the compatible devices, so i think is has to be something else...
[Paid Software Announcement and Discussion] pspilot:
Just out of curiosity, what happened to the power switch on your camera and why and HOW did you do that (resetting)? I never resetted my DSLRs :confused:. Only the loss of all CF.n's would cause me nightmares.

I understand and I have no good suggestion for that. Also, even if it would be nice, the AEM switch is not the most important feature. It would be just a matter of 'completeness of remotes' :).

Brilliant, thanks!

I ordered a new OTG cable from Amazon, expecting it next week. I'm really curious about these USB problems. Using a 15 cm cable is obviously not the solution :D.

Well, it should be micro, not mini USB and then connect the key pin to ground (apart from the usual USB connections of course) - that's it.
[Paid Software Announcement and Discussion] jabbado:
Chainfire, I mentioned a couple of ideas I had that would be interesting features for me at least. Maybe it's a little too early to think about incorporating them but I'll ask anyway.

What about adding sound and light trigger options? I'm not a dev so aren't sure about all the implications/difficulties in getting these to work so am just putting the idea out there.

As for sound, I don't know if it would be fast enough to capture a bursting balloon or a hammer smashing a glass. But it could be useful in certain situations, and also used to take a photo by clicking your fingers or clapping your hands, without touching the phone.

With light triggering, I was thinking of using it to capture lightning. My initial thought was to use the ambient light sensor to detect the lightning flash, but after playing with several sensor apps it looked like the light sensor couldn't fire off change events fast enough for this, or if it had enough resolution to detect the flash effectively. Also another way of using the light sensor would be as a "beam trap" - pointing a low power laser at the sensor and when something passes through the beam the shutter is activated. Again this depends on how fast the sensor can respond.

If using the light sensor isn't possible, then what about using the phone's camera preview? For lightning you'd only have to check brightness changes in a few areas, which should be quite fast to implement. A few years ago I was following the CHDK project and they'd incorporated motion detection into it. We seemed to be getting response times in the order of 100ms or less, which is quite ok for capturing some lightning strikes (I actually captured a crappy one during testing the MoDetection scripts, hand-holding the camera in daylight). I'd be surprised if an sgs2 couldn't get better response time than my old A610 with CHDK installed.

Yet another way that might work would be to have the camera in live view mode but only grab the histogram data instead of the full preview image. Use the histogram to detect brightness changes and trigger the shutter. This would be faster than downloading/processing the entire live view data, wouldn't it?

What do you think? Would these ideas work?

Timelapse is working great.

Did a 1.5hr 300 frame shoot and a 2hr 600 frame shoot. Batter drained somewhere around 25% for both.

No issues with it at all. It's great that I can switch to live view on the camera to check my exposure during the shooting too.

I was also doing this with the rather long 1.5m usb cable that came with my 500D and had no problems. Same with the 30cm cable I was using before I dug that one out.
[Paid Software Announcement and Discussion] jeffp25:
The USB spec. does allow for USB cables up to 1.5m/10ft. The only issue is if you have a poorly shielded cable, and it can help to have a noise choke (one of the ferrite ring things) on the cable. But unless your transfering image files down the cable, the communication in remote control mode isn't very demanding.
[Paid Software Announcement and Discussion] defroster:
To answer my own questions; not without external power :( , yes with pin 5 grounded, fixed it via mechanical repair.
[Paid Software Announcement and Discussion] softimage69:
Thanks for the reply. Can you check something for me? Under the tablet system settings, check "storage", then "usb host" (at the very bottom)". When the camera is connected, USBHost is darkened out (not being used I assume). If i plug a USB stick instead, it turns white and says how much space is available.

I just installed DSLR Controller, but it returns the same error.

Thanks again for the help
[Paid Software Announcement and Discussion] pspilot:
Where do you have that from? The official USB org allows 5m for USB2 (scroll a bit down).

The demanding timing of USB2 is not related to the amount of transferred data. If the cable doesn't meet the specs, even the initiation will fail - which happens with DSLR Controller btw (I mean, it doesn't fail during a pic transfer, once it's connected).

But originally I wanted to tell about my new assumption, that the Galaxy Note has some 'weaknesses' regarding the host mode. Maybe the (hardware) drivers are poor or the V+ supply is weak or whatever. I'll look into that, as soon as I can free my measurement gear from the unavoidable lousy daily work for a living :D. This morning I received the other OTG cables I ordered (Amazon) and they're not working either. The trouble is, they're not even working with a simple USB stick - so it's definitely not DSLR Controller related. But Chainfire & users might be still interested in the fact, that some Android devices have obviously 'sloppy' USB-OTG implementations. BTW, I ordered 2 cables, both are failing, it's not a failure of a single cable. This is indeed a bit annoying ... thanks Samsung, another one you failed :rolleyes: ...
[Paid Software Announcement and Discussion] defroster:
Maybe you need external power via Y cable?
[Paid Software Announcement and Discussion] kindsma1:
Hi,

Actually when I open DSLR controller successfully and try to return with the home button to settings, DSLR controller is shut down, so I can't verify what the activity is at that stage...

But try this. When I open the app and simultaneously press the shutter button on the camera I can access everytime.

Otherwise, If this does not work, I'd suggest you to test with several USB-to -microUSB cables.

The Usb-host cable presumably must work for you, if you get the usb stick to work with it.
[Paid Software Announcement and Discussion] pspilot:
Well, for the stick it would make sense, but not for the camera. The camera needs the V+ only for the pull-ups on the data lines to start communication. It actually doesn't need 'power' in terms of 'energy'. And if there wasn't be good V+ at all, the short cable would neither work. Actually I assume only crappy cables so far, seriously, Chainfire might be right. The cables are all dirt cheap but crap. Let me do some research on that, I'll come back :).
[Paid Software Announcement and Discussion] gadgetfl:
The slow USB 1.1 specification defines a maximum cable length of 3 meter, and the faster USB 2.0 specification allows 5 meter cable length.

Reference

I personally use a 16' passive repeater cable then a 3' cable with a clip on my belt connected to the camera. If I pull to hard, the repeater cable unplugs from the OTG adapter or the belt clip cable without putting stress on camera or Tablet. I have successfully used 2 16' passive repeater cables without issue.

Generally, because I usually shoot handheld with a Art Director holding the Tablet, I position the middle of the cable behind us and place a weight bag on for added strain relief and to prevent it from getting in the shot.

Missing exif info

Ok, I see. The whole row below an image in info mode is not visible at all with DSRL Controller 0.86, SGS2 (2.3.5 stock rom) and 5D mkII!
[Paid Software Announcement and Discussion] MrKwatz:
Noticing some issues with shooting.

When switching AF/MF with the hardware switch on the lens every option in DSLR controller will become greyed out. When I switch back to the mode that the camera was plugged in with initially the options come back, but when I actually attempt to change them nothing happens. It doesn't let me select anything (as in it doesn't even highlight any of the choices I touch in the exposure menu, it just sits at the current one and doesn't go away).

I have tried 4 different usb cables attached to the otg cable for the tablet. Thumb drive works with all cables on the tablet, and all cables allow communication with the canon eos utility app in windows. I also tried the shutter hold-launch app test but no go... i am not sure where to go from here...
[Paid Software Announcement and Discussion] Engelhuber:
no one with a modded SGS kernel and a working DSLR Controller ?! :(
[Paid Software Announcement and Discussion] pspilot:
Sounds clever :). Do you have a brand of these repeaters or even a link? Though, I think the entire subject changes from device to device (Android device that is).

That's what I mean. The (hardware) drivers of a PC might be totally different than the ones in a mobile Android device. Especially the need to preserve power in the handhelds interferes pricipally with the quality of line driving. The cables I have trouble with on my Note are all working perfectly with the PC (Notebook).

Hi,

Try this then, I searched aerlier posts as I remembered that somebody earlier posted something that he got it to working like this (other tablet same kind of specs). This what What I found:

"Connecting Camera, starting camera , starting DSLR Controller - not working

Connecting Camera, starting camera and DSLR Controller at the same time - works perfect

I must start the app in the timeframe, when "BUSY" is shown on the Canon LCD" ...

This is true for me as well, I get the "BUSY" on my camera screen as well when I start it up.

Unfortunately, I have no more ideas than this. I can of course take some pics of my setup and working DSLR controller, but that's about it.

for the reocord:

Haven't altered anything really except the Lord BSM's market script and still on stock firmware (not rooted) . Haven't set the vm heap size-limit to anything else either, it's stock, and when starting app gives me message "medium memory value- 128mb" (or something similar).

Does Chainfire have any more ideas?

One thing I should note on the repeater is that it HAS to be a powered port to work.
[Paid Software Announcement and Discussion] gadgetfl:
I use the same one

That is very true. I have a Xoom, not sure if it has a powered USB or not but it certainly has a strong signal.

At one time I considered putting a powered hub between the 2 passive repeater cables for signal boost but I found I did not need to.

Your mileage may vary

I am considering trying one of these:

33 ft / 10 meter Premium Active USB 2.0 Extender

For $16 if may be worth a shot.

Feature request: remote control for DSLR Controller

Chainfire,

I read through most of this thread, however I'm not sure if this feature has been requested before explicitely:

Can you add options to remotely control the DSLR Controller App and thus the camera? For instance, using wifi/modem and/or SMS/email to launch and set-up DSLR Controller and start shooting... typing SMS keywords to set up the camera (e.g., "Av 5.6; Tv 1/30; start; 10 [picturesTaken]; 5 [seconds interval]; stop; closeApp"). Or transfering the live view image via wifi to another device...

I reckon this is not on top of your to-do list and maybe beyond v1.0, but I assume it would yield lots of new possibilities to use this fantastic app.
[Paid Software Announcement and Discussion] Chainfire:
Sorry for the long response time.

Please check if your specific kernel supports USB host, if a separate powered USB HUB is needed, and make sure it works with a USB stick.

Both of these are under consideration, though it's likely that if implemented, we'll see #1 well before we'll ever see #2. #2 was actually on the to-do list already, but low priority.

1) Maybe with Sztupy's modified kernel and a powered USB hub. Will certainly not work connected directly to the phone.

2) No, you need a "USB host" cable.

3) No.

I'm using DSLR Controller with a 550D on an I9000 with Sztupy's kernel and it's working fine. Try Sztupy's kernel, just to be sure.

These are certainly interesting ideas, and rest assured, I have not forgotten about them since you mentioned them earlier. I have actually played with light detection for the timelapse feature, but in the end I stopped playing and just released the timelapse function as it is now.

Anyways, I still want to see if these ideas can be implemented (they're on my todo list), but even when basing on histogram data I think we should expect +- 100ms latencies. Using the histogram will be much much faster than processing the entire liveview image, however, the histogram data you see on screen piggybacks on the liveview packets. In other words, I can't download just the histogram data per liveview frame, I have to download the frame itself as well (but not necessarily process it).

Can you screenshot this or take a picture of how it looks on screen? You do see the histograms? Also, which image quality mode are you shooting exactly? raw+l, mraw2 + s, etc. Kindly take a picture the exif info does not show up for, and upload the result file (or files if you are saving in two formats) somewhere, and link them here, so I can download and analyse that file.

Does this always happen or did it just happen once? This behavior is consistent with entering focus mode (focus rectangle will be green on screen), then setting the lens to MF ... Other than that I'm not sure what might be going on here.

Should be back up!

I'm using TeamHackSungs's ICS (Build15) with sztupy's kernel (Build5). DSLR Controller needs a couple of tries to get my cam (D60) recognized. It might help to press the cam's focus button (and disable Auto-Power-Off).

@Chainfire: Sometimes while playing with DSLR Controller, my cam seems to freeze. Nothing helps except pulling the battery. If I can provide any log or info to help fix this, please let me know.
[Paid Software Announcement and Discussion] k-m-c:
fair enough... for most people it's the same situation with "already a few cameras and lenses" of Canon/Nikon/Sony/whatever around

Ultimately, for most applications like timelapse, HDR, stereography or a combination of those, it would be nice to have an open and customizable image acquisition unit (sensor plus some circuitry) with adaptable high grade lenses and a remote controller software like DSLR Controller.

Ah, stop dreaming and get back to work! ;)

Hmm. I started working with USB devices when USB 1 first came out. The company I worked for developed biotech equipment consisting on multiple modules communicating with an internal PC. Switching to USB (once it was supported by Windows) made things much easier than using standard serial ports or some of the more esoteric communication standards they considered. I did a lot of the hardware/software testing and at the time (mid '90s) the engineers insisted that the USB cables could not be more than 10' long. I heard that from many people and I'm pretty sure I saw in some of the documentation from our suppliers. But after checking your link, I don't doubt you about the 5 meter limit. I wonder if the engineers I worked with got it wrong, or if the limit changed as USB was implemented?
