Re. DIY pendant - there were a few posts from 2020 but I would appreciate if anyone could comment on their experience.
I am running Mach4 on my CNC and wish to add a pendant. I have built Simon Rafferty's design from GitHub.
My Mach4 screen set recognises the pendant, I can monitor the serial data which appears to be correct so far but the display is not updating. I suspect that my problem is with the Hunda HB35-1C display.

Has anyone had success with the Visual LCD Display software? I can compile, download (upload) the Hunda example and Simon's script to the Nano.
I can compile, load and get the example to work with the Visual LCD Studio software.
However the Lcds Test & Touch Panel Test do not appear to do anything.
I have Visual LCD Studio software ver 1.1.2.0. Is there a later version?

Thanking you in advance for any help.

Hi,
what motion controller are you using?. Do you have five , or six or more spare inputs?
If you do why shag around and just make a wired pendant?

I made one to replace my VistsaCNC pendant, I wore it out over seven years and thought I'd make one.
Real simple, has two wires for axis selection, one for velocity/incremental mode, two wires for A&B of the MPG, and two wires for
power and return. Seven wires but only five inputs required. Works OK.

from his github:
The vendor will send you a link to the software & documentation. The link they sent me is below, however I dout it will persist there very long. If the vendor won't cooperate, message me & I'll send a copy if I still have it.
looks like a finalized or dead endeavor.
