I got a pcf8583 tachometer and wanted to connect it to my Holybro pixhawk 4. I noticed the parameters as listed here were not found in QGC. As the site suggested, i added rpm/pcf8583 to the cmake file for the board and builded it. after uploading the latest version to the pixhawk 4, it still not showed up in QGC. I looked into the parameter.xml file in the build folder, it had the specified parameters. when looking in the ParameterFactMetaData in from QGC, it also has those parameters, but still it is not showing up in the GUI of QGC.
I also tried installing the latest stable version of PX4 onto the board, but that didn’t change anything.
anybody knows what i could do? I installed the developer toolchain so i can edit files and make custom firmware.
thnx in advance,
