RPM-Signal

Post by fasthd »

Hello Forum,

is it possible to put realtime Engine Parameters (like RPM, Oil-Temperature) trough the OBD-Emulator so that a connected OBD-Reader Shows this Parameters along with the emulated parameters?
Is there any Interface at the OBD-Emulator for that?

Sorry for my bad english.

regards
Frank

You can programatically change the value of emulator's OBD-II PIDs by sending AT command via USB, BLE or serial UART (the 6-pin connector).

Hello stanley,

thank you for the reply.
Do you mean I need to take my Engine-RPM-Signal and convert it to AT-commands?
In this case how many changes per second can be send through the Serial Interface.
Or I am on a wrong way ?

Sorry for these strange questions but I must emulate some PID's along with some realtime PID's so that a OBD-Tester shows These Parameters in once.

Regards

The speed can't be very fast as for the 38400bps serial baudrate.
