SPI slave maximum speed

Post by mfpleite » April 4th, 2018, 2:07 pm

Hi,
I am trying to read messages from a SPI, as a slave, and at a rate of 46MHz. Will I be able to do this with the Mojo v3? Are the digital IO pins fast enough?

Many thanks!

You can definitely achieve rates much higher than this with the Mojo. The FPGA's pins can reach hundreds of megahertz with a few tricks (none of which will be required for your project).
