Thought I would share what i've learnt after hacking at this for the whole weekend from a complete newbs perspective (compared to Arduino)
The STM32F1 is a great low priced board for (under £20) loads of functionality
Got ds1302.h off the arduino site to work, had to alter sketch
SerialUSB (not serial.) unit8 (not unit_8)
#include <stdlib.h> / #include <stio.h> also missing.
Sketch now works, will compile - upload and run
Using Ubuntu 12.10 and have been having issues....
- it appears that maple-ide runs better as root, sudo maple-ide ?
- To upload sketch have to press Reset switch after clicking upload
- Serial window is very flaky....
- maple-ide crashes alot, possible bug when its trying to open file that it hasn't got the correct file path for ?
