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?
Thanks.

This is the oddest place to ask an SPI tech question …
Since I’m not familiar with spi on this device I can only suggest obvious stuff like double checking that you setup all the registers and connected all the needed pins (enables/selects/clocks). After that there are a million tech forum out there with people who really know this stuff. Google will show the way. I’m sure you’ll figure it out … and remember … you’re having fun.
