Hybrid Flash ECOTEC PCM ONEROM-ESP32S3 DASH

Post by Muncie »

This is my current state of build.

Part 1
Ive integrated the onerom into the PCM as an emulator that part has been running in my car for a while and works perfectly.

Part 2

Ive worked out how to get behind aldl and got ONEROM outputting over usb c to the ESP32-S3 its still in debug but has run at up to 25hz dropped back to 10hz for in vehicle testing once everything is reliable I will start making the dash look more hi end.
