Does this look ok to get the encoder PV1 counting? PV1 should be the MPG socket. I don't know if I have a hardware issue or code issue. Also does the nvmpg.so need to be compiled first? I'm using an adum1200 to bypass the opticouplers. PV1 does not count when I move the encoder in Halshow

Hi, are you using the nvmpg or just an encoder?

The nvmpg component does the communication for the screen updates and button press receptions. The nvmpg LinuxCNC component needs to be enable in the ini file to use the remora-nv-mpg.hal file. Encoder pulse counting is done in software on the LinuxCNC side. So slow speed counting.

Encoders require the QDC module to be enabled in the config.txt file.

eg  Remora-RT1052-cpp/LinuxCNC/ec500-rt1052-DMA-ENC.txt at main · scottalford75/Remora-RT1052-cpp

Example encoder hal file

That's very kind, thank you.

Check with "ls -l /boot" if all links are correct. With Armbian for example the Image file is a link to the used kernel. To relink you can use "sudo ln -sf your-rt-kernel Image" and also check for the uinitrd link and to use the right dtb for that kernel version.

I saw that it's a rk3399 indeed, but here it also worked great for a s912 sbc so it might be a good base for yours too.

It's only those two buttons and I already have a fix in my mind as soon as work is over I'll implement that.

Ok never mind i did have a very small blow out I didn't see in the tip. so that would account for the raised HC look
