Hi,
maybe someone can help me out.
It's about the STM32F401. For a few days I'm struggling now but
still no I2S data or clock activity shows up at the 4 SPI2 peripheral
outputs. All stay low. I like to configure all uC registers by hand
for learning purposes.
The SPI2 peripheral should produce I2S data. If 16-bit values are
written to the SPI2 data register the debugger shows that directly
after a new write the TXE bit in the status register is cleared and
then reappears and n
