Max and min SPI speed


What is the maximum and minimum SPI speed?


max is 36Mhz, min is about 1Mhz but I can’t remember.

I think GHI was going to enhance this to make it possible for SPI clock run at lower rate.


Can you give more information about this update from GHI? I need to operate the SPI bus at 100kHz or less on the USBizi. Thanks!


You have replied to a post that is 6 months old. GHI has released 4 or more SDKs since then.

Download latest sdk and try 100khz please


I’m using SPI down to 1kHz with latest SDK on FEZ Panda II and it works fine.
