Hi Christian, sounds like the behaviour of the earlier firmware. I've cleaned up my Github so that only the latest tested firmware is there. I've tested this firmware with my NVMPG and it's working as expected.

Hi Scott,

You are my hero. With the new firmware everything works as it should. Terrific. Now it can go on. Thank you very much for your work, your development and your support

Great to hear that you are up and running. Does your board look like mine or the "newer" version with the PWM to analogue chip? If it has the chip then the 0 - 10V should also work as it's using the same code as the NVEM.

 I'm interested to know if they have been "upgraded". If it's a newer version than the one I have, even an STM32 I'd welcome the donation so that I can confirm the analogue output is working. I've not been able to get it working on my version of the board.

For sure, and if you were interested in the Expatria Teensy grbl PCB from Russell we'll send that with it.

Thanks and thanks! My email is ...... deleted

Bumped into this, with all the reverse engineering going on might be useful to someone.
If not, let me know so i can remove it.

Cool, the new NVEM has external QSPI flash. Hopefully we can read using the i.MX RT Flashloader or NXP-MCUBootUtility.

Can you confirm iff the 0-10 volt is working?

So at this stage I'm not sure if this is good or bad but my NVEM "V2" has arrived and by the looks of it has the NXP IMXRT1052 chip...
