Hi,

I am trying to send data via SPI to a Sensor and receive data from the Sensor. Therefore I tried to establish SPI communication, but it does not work. There is no clock Signal on the CLK pin(PA5). I attached a part of my code. Maybe there is something wrong in my configuration?

Regards,

Alex

Don't know, but you'd want to qualify TXE before jamming data out with the SendData()

Don't know either, but are you aware of the fact that PA5 is NOT 5V tolerant?
