Hi all, looking for suggestions,
I'm hooking into my Links G4 can bus with a home brew module consisting of a PIC micro controller + CAN controller / transceiver that will give me up to 8 x 0-5V analog outputs and a few digital in / outs. Sum total of parts $15. (Programming and development..... lots of hours, but my time is free)
I have tested a VDO oil pressure gauge and I can successfully mimic the operation of the sender via PWM and 1st order filtering to a transistor that provides the current sink for the gauges sense terminal.
It's not an elegant solution but it works. What I am looking for is a gauge that takes 0-5V and is available in a range of common display types like oil / water temp, oil press etc.
I've been googling around, but nothing is coming up? I have seen dedicated canbus gauges but they are so overpriced and I am not sure if the Link CANBUS operates to a particular automotive standard for its peripherals that I already have hanging off the bus so they may not work.
Any suggestions for 0-5V or something similar?
