Hi Mark, I'm really interested in the down-stream OBDII connection (ECU emulator). I would like to use it to drive a Wi-Fi Hotspot dongle (T-Mobile's "SyncUp Drive"). Thanks for including this. Besides providing a hotspot for the car's passengers, and the intended vehicle telematics, it could also give the OVMS module a Wi-Fi alternative to the 3G modem, at least when the car is awake. I presume the modem would be the preferred connection for lower power states. Greg Mark Webb-Johnson wrote:
Along with some HUDs, I’ve been experimenting with a little OBDII display that costs around US$25 (quantity: 1). Connection is via OBDII (CAN bus) - the idea being that we will emulate an OBDII ECU on one of our CAN buses that connects to this. So, we can output battery temperate where the unit expects coolant temperature, SOC% as fuel level, etc. MCU in that unit is a GD32F103 (like an STM32, but 108MHz). Input is via a little jog-left, jog-right, push-to-click button on the front. Just an idea and something I’m messing around with.
