the sampling logic and countig is not very standard:1) If A = rising edge and B = 0, counter++2) If A = falling edge and B = 1, counter++3) If B = rising edge and A = 1, counter++4) If B = falling edge and A = 0, counter++5) If A ...
Hi, I have a problem where my SPI SR RXNE in STM32F302R8 is never SET, causing my program always halt in while loop, waiting the RXNE status to become SET, when receive data.how I set the RXNE flag is below:#define SPI_SR_RXNE 0#define SPI_RXNE_FLAG...
