That micropython looks great. Did you get one of their boards? I have a "FEZ Cerb40" (STM32F405 I believe) https://www.ghielectronics.com/catalog/product/353 that I think I could run it on but without SD card I'm not sure how easy it would be to get files onto it. Would you know?

Hi Mark, I've recently been playing with MicroPython ( micropyton.org ) which runs on an STM32F405 (Cortex-M4 with FPU). I really like the builtin DFU bootloader (no programmer required). STM seems to have a nice peripheral library. If you're looking for something that works on m

It is easy enough to store a pointer to the register ( PORTB ) and a mask in the class. This may be the most generic solution available. If both values are stored constant ( in the case of the port register, volatile uint8_t * const ) the optimizer will sometimes even find the pr

Hi Steve, What happens if you put in a delay at the start before you send the byte? What fuse settings do you have for startup? I've never used the fast options, always slow start and this has proven reliable. On a system I did years ago, I had a similar issue with the serial por
