Change SPI speed

Post by PeterG » Mon Dec 31, 2018 5:38 pm

Hello,

How can I change the bard rate of the SPI transmissions on a STM32F4Discovery board? The board is clocked at 84 MHz. This yields a slowest baud rate of 328125 bits per second because the prescaler has a max value of 256. I would like to get the baud rate down to below 10 kHz if only for testing purposes.

Thanks in advance,

PeterG
