Hi all
I need to be able to generate CRC's quickly, I know a lot of IOT type processors have hardware CRC engines, is there anything like that available on the Omega, at the moment I'm using crcmod in python and its astonishingly slow, I have an 8MHz 8-bit PIC producing CRCs at at least 10x the rate! I guess I'm learning about python quickly!
Thanks
Ed
@crispyoz Thanks, seems to have worked, that you! Now I just need to figure out how to import a c crc engine into my project as crcmod in python is ridiculously slow - if you've any ideas I've started a new topic.
Followed this guide on my Mac, for to the point of running make in my docker environment and I'm met with this output
