Thank you very much Canne for your heel sensor stuff. It worked great for me even without any previous experience with microcomputers. Intel gave up on the Arduino/Genuino and I found none on the market but there are still stocks of
CurieNano available but who knows for how long. It took me some hours to get up to speed with the Arduino
environment, but then it was just "plug and play", guided by the graphial interface. I gave up on making PUTTY work for me. The
serial console of the Arduino
environment was much more intuitive for a beginner. Your
software got a few compiler warnings about syntax which I generously ignored and that was it. The
CurieNano actually has some advantages over the original for this
project. It is more compact and includes a 3 axis
compass sensor on board, which would allow making a 9 axis device. They cost 36$ out of
China, but I bought mine for 52€ in
Germany. You can find much cheaper HW than that, but the availability of your SW made the deal for me. I had a hard look at the code and documentation before going for it, as well as your other contribution on the Forum and your professional background ..... simply impressive.
Here is my "nano-version"
If somebody wants a copy, you need
Cannes Software and one piece each:
- CurieNano
- Case: Hammond Electronics 1551USB3CLR (2,95€)
- Transparent Micro-USB-cable (Delock) (1,53€)
- polished aluminium block ca. 24x12x5 mm.
- Neoprene pad ca. 24x12x4 mm.
The opening at the front of the case is for a type A USB-plug, a tiny bit wider than the plastic isolation of the micro B Type
plug which connects to the board but 4 mm lower. Making use of the transparency of the plastic isolation I grinded 2 mm deep slits on the top and bottom to fix the plug in place when the case is closed. At the back end of the case the soft pad is glued to the bottom part and above the Curie processor the polished aluminium block is glued to the top, acting both as a heat spreader, as well as pressing the board, which is fixed in the USB plug at the front end lightly onto the soft pad at the back. The heat spreader is luxury. I happened to have the material lying around, but the board could just as well be fixed with another soft pad in the appropriate place.
