Posted on February 13, 2013 at 17:41Note, that PWM is the functionality of the timers (TIMx), so you need to learn first which of the timers support PWM, and then look where are the timers' pins. Also, all IO pins can function as EXTI, but not at th...
Posted on February 13, 2013 at 14:06Hi, I have successfully programed and debugged my chip many times with toolchain from subject (IAR 6.30.6 + OpenOCD 0.6.1) and everything worked just fine. Then something went wrong. After download IAR threw a wa...
