How to get RPM Readings from Jet Cat Engine ECU-Mission Planner

I’m trying to connect the RPM 2 on the Jet cat ECU v12.0 to the Pixhawk Orange in Order get the RPM from the engine. I’ve tried using the RPM1_type to GPIO and RPM1_PIN = 55 (AUX 6) but not able to get the RPM in the mission planner. And i want to know what type of signal is coming from ECU?. Do any one tried this before. pls do help me.

This is not a mission planner issue. This is an ardupilot issue. And you provide not enough details for us to help you.

Yes. Its not a Mission Planner Issue.

I trying to get the RPM from the Jet Cat ECU to the Pixhawk Cube Orange. Using the Aux (6)(GPIO).

Parameter Settings:
RPM1_type = 2 (GPIO) and RPM1_PIN = 55 (AUX 6).

But I only see -1 in the RPM1 variable in the workspace.

RPM2 is not an output, its an input for a second shaft speed ie turboprop application. You should go the canbus option and get all the data

Any Other Options without using CAN Protocol?. I don’t think ECU v12.0 supports the CAN.

The pro version does

There’s is an option to get the telemetry from the ECU shown in the figure Symbol (T). But, I’m not sure about the connection to Pixhawk Cube Orange and get the data.
