Hi,
I work on converter analog signals to PCI-Bus for Jeep WJ 3.1TD, to alive my gauges in my Grand Cherokee. Daniel prepared for me Arduino's sketch (attachment).
Battery, oil pressure, coolant temperature and fuel level - analog inputs
Two pulse inputs for car's speed and RPM. Pulses are switched to GND (Hall output).
Unfortunately my car has moved out original ECU and BCM, and no longer PCI data comming to gauges
Different engine, different automatic transmission.
With attached sketch fuel gauge, oil gauge, coolant gauge works (gauge's indicators moved when rotate potentiometer).
Battery gauge not mooved, speed and RPM not mooved.
Battery input with voltage divider 3.9kOhm and 1kOhm. 14V input = 2.857V output. Actual ADC reading 12V - ADC 483.
I use Arduino Nano.
Can U help me to run all gauges?
