Posted on October 08, 2012 at 16:06It seems I can't correctly initialize the SPI pins on the STM32L-discovery board. I have very little experience with programming 32bit devices so I am probably missing something obvious. I hooked up my oscilloscope...

Posted on October 22, 2012 at 12:41Actually I have and used my scope and the code works correctly. Only the speed of the PWM is so low that I can clearly see the the on/off action from the LED. How do I set the core speed exactly?

Posted on October 18, 2012 at 16:06The code works for me but very slowly. I can actually see the PWM(on,off,on,off...) what configuration am I missing?

Posted on October 18, 2012 at 15:53Thank you for the help everybody. I have managed to get a SPI signal for the board, looks good on my scope. Somehow my MCP23S08 chip doesn't react. I have checked the wiring and I am guessing that maybe the clock a...

Posted on October 09, 2012 at 12:29I don't really believe that you are not getting any help on purpose, it's probably a communication problem. That being said, I really need to use the built in SPI module, I'm doing a research project for my univers...
