S13 SR20 realtime news

Post by Matt »

well i finally got our SR20 prototype board programmed and all was working well. it does nvram writes and reads in realtime 16 bit through the consult port

however there is a fundamental flaw which prevents the chips from saving the data permanently. this will require a minor design change and several changes to the PCB layout. we were using SPLIT implementation but this will need to move to ODD/EVEN

proof of concept works none the less but unfortunately its more time taken to get another prototype board made up and tested

I also have access to SR and KA powered cars for testing when the time comes.
