Posted on March 04, 2014 at 13:59Hello, We use STM32Fxx MPU in many projects. During the developmentof new equipment with STM32F427, we have run into this problem:We useSPI4, which is controlled by the DMA. Streamer DMA2_Stream1 is used for sending,...
Posted on March 05, 2014 at 15:52Hi guys. I know some of you guys have done something like this. I would like to implement the TIM1 to generate a clock, using it as a PWM out-up mode, but I wish ( if it is possible) modify its functioning to generat...
