content: on the link they show the 868MHz as being acceptable for Europe and India, the 915Mhz for Norht and South America. 433MHz world wide.As for equipment other than the CC1111 access point, I guess you can look for devices they mention on the page:Can be paired wirelessly with heart rate monitors, pedometers or other devices based RF transceivers like the CC1101 or SoCs such as the CC430 or CC111x

content: Quote from: sfiber on July 08, 2014, 06:32:04 pmKeep checking and hope that the 433 MHz version gets back in stock I suppose. I wouldn't count on it though. It seems to already come with a USB RF transceiver so you can at least connect wirelessly to a PC. I haven't looked into any other communicating devices.

content: 433Mhz allocation has been sold. No more will be added. This was the more popular frequency and TI state that they allocate a certain number to their offers on a first come, first served basis. When they are gone, they are gone.Aurora

content: project (not really related to the watch but they decided against the CC1101 because the 915Mhz is too noisy, also the CC430 that they contemplated (the one in the watch) was delayed. But the rest of the project might apply something someone might want to play with.http://eecs.ucf.edu/seniordesign/fa2009sp2010/g07/SDFiles/Wireless Heart Rate Monitor.pdf

content: The 433MHz would have been cool but it opens too many concerns (and garage doors/security systems and other devices). I can see why TI made a limited amount of them.Now the CCS has a 16KB code size limit on their free edition, the other free IDE has an smaller code size limit of 4KB. As far as I can tell the 2nd one IAR i believe it's called, doesn't bring anything more, but there seems to be other options.Here is TI's wiki with tons of information and links:http://processors.wiki.ti.com/index.php/EZ430-Chronos

content: Some trivia ...... Ti advise that the 868MHz and 915Mhz versions are identical hardware with software selection of frequency. The 433MHz unit is unique and is stated to have less range than the 868MHz and 915MHz versions.Aurora

content: IAR Embedded Workbench for MSP430 has a 'kickstart' edition which is limited to 4kb. IAR make the compiler/linker themselves. It is more efficient in code size/speed then the GCC when pushed to the bleeding edge. Partly because of the compiler, partly because of the linker and partly because the c librarys are optimized.

It is the same with temperature, But i am not quite sure where it is read from yet.I also just wore mine around all day. Wanted to see how comfortable it was. So far its not bad, a little on the big side for me. One bad part is the back light. It is very weak. Looks decent at night though.Lets start a thread in the microcontroller section so as to not clutter up B/S/W.-Crab

content: Quote from: miguelvp on July 11, 2014, 11:50:24 pmAltimeters based on atmospheric pressure need to be calibrated to the known pressure at your location before every use. That's why pilots calibrate their altimeters before flight. You can get a close approximation by looking at the weather forecast from the airport closest to you. Of course, this doesn't apply to GPS derived altitudes...I just received the 915 MHz version of this kit today and have no clue yet what to do with it.

content: The problem with wearing it as a watch is the face seems to be basic un-toughened plastic. Mine has a gouge in it across the bottom and it wasn't like I was doing anything unusual for the few days I wore it as a watch.Longevity it has not got.
