SPI Clock Pin No Output
I am using STM32F103CBT7 for my design with HAL functions at 72MHz system clock.
SPI 1 is configurated as Master, 16-bit data width at 18 MBits/s.
When sending data out, there is data bit on MOSI pin, but there is no Clock pulse on SCK pin.
I cann’t not figure out what is wrong.
Any suggestion?
Thanks.
