This board is pretty ready for review.

Hey guys

I've been doing testing on this and I have to say, I am impressed by how well it works! We're doing more dev testing, and here are a few videos!





I'll keep posting on here when new progress is made!

Next step we need some CAN Lua for A/C logic

just a skeleton for now:

Code: Select all

-- listen to CAN ID 0x500
canRxAdd(0x500)

-- todo: add payload logic
packet546 = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06 }

function onCanRx(bus, id, dlc, data)
	id11 = id % 2048
	print('got CAN id=' .. id .. ' dlc='  .. dlc)
	-- todo: add filtering logic if needed

	rpm = getSensor("RPM")
	-- handle nil RPM, todo: change firmware to avoid nil RPM
	rpm = (rpm == nil and 0 or rpm)

	if rpm > 800 then
		-- at the moment we simply
		txCan(1, 0x546, 0, packet546)
	end


end

function onTick()
end

Norman, spoke to Andrey. Need to give you heads up.

ECU will need to output AC Pressure, Coolant temp, and current AC status.

I'll attach wiring diagram for you below.


ECU on this car also reads ac pressure sensor.
Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA]
