Jeremy Posted November 18, 2021 Share Posted November 18, 2021 I am using STM32F103CBT7 for my design with HAL functions at a 72MHz system clock. SPI 1 is configurated as Master, 16-bit data width at 18 MBits/s. When sending data out, there is a data bit on the MOSI pin, but there is no Clock pulse on the SCK pin. I can't figure out what is wrong. Any suggestion? 0 Quote Link to comment Share on other sites More sharing options...
