Posted on March 13, 2015 at 16:17Hello,
I'm running an STM32L151 at 32MHz and SPI BaudRate = fPCLK / 4.
The device is an SPI Master, and tries to read a Slave as fast as possible.
I'm using DMA TX and RX to speed up things.
I can see the SPI clock running at 8Mbit/s clock, but I still get approx 1.5 µsec timeout between each transmitted byte, which in the end reduces the troughput to less than 4Mb/s
Is there anything I can do to help reduce this latency ?
Thanks for help.
BR,
Vincent.
