I tested the MQX SPI example in folder MQX/examples/spi. I used the Vybrid pcm052 board / M4 processor. I changed the baud rate to 1000. I read back the baud rate, it returned 1017 ... no problem here.
On the scope, I measure a clock rate of 2600 Hz which gives 333 byte/s (1/2600 * 8bit). I'm a little bit confused.
Can anybody explain me why ?
