SPI speed

  1. Hi guys,

    I am wondering if we have a chance to increase the SPI clocking speed (as well as I2C).  I am trying the SD card driver of Telit and data rate is very slow unfortunately :((  What can I do to increase the write & read time?

    Kind Regards,



    1. From what I know no, unfortunately, being a software implementation, however I didn’t tested with #CPUMODE fast, maybe that will bring some gain.


      Are you testing with standard driver or with changes shown in forum?
