content: I just got a RT809F on eBay which is primarily a programmer for firmware on LCDs and can also be used to do some diagnosis on VGA DDC data. It can read&write firmware either through VGA/HDMI or serial NOR flash (in common SOIC8 or SOIC16 packages) directly through its ZIF socket. The latter is my primary purpose for this device.The MiniPro TL866 does AFAIK not support this type of serial NOR flash hence this buy. I will mainly use it to program Spansion S25FLxxxKs for some LED display projects which need fast random memory access (lookup tables) from a small MCU. The more serious competitor in this space seems to be the Dediprog SF100/SF600(+) but at $275 compared to the $55 I paid for the RT809F there is no contest given my very limited usage.The software comes on 2 packed 4GB DVDs (!) which is full of firmware and maintenance manuals for hundreds of LCD displays. I am not sure of the legality of distributing that… The main interface is crummy as can be and the main reason this thing is only $55The main issue I had was that S25FLxxxKs were not the list yet but I was able to add the device IDs into a user defined list the software supports; as long as the protocol is the same as some other device in the built-in list. The RT809F does not seem to support as many flash types as the SF600 so I recommend to check the supported list in the latest software before buying (you can get the newest english version of the software on some obscure Chinese website).The software can also be used to debug the DDC channel data if you pass the VGA signal data through the device. I haven’t tried that but it seems fairly handy if you need to do repair work on LCDs. There is more stuff like test patterns and the like but again I have not tried that.
