USB haas operator panel interface

while using a micro between the VFD and the computer in the system I have would be a fix for the ability to reset the VFD, it doesn't address the other issues.

Also I want to experiment with the STM32 as a sserial device.

Hi Chris,
that means you only need one IO.
Its ok. I try github.com/fdarling/mesa-smartserial-device-template . it is usable on stm32. there are 32bit in and 32 bit out.
the only thing i didn't find was the writing parameters. but that is not necessary now.

That looks very interesting.

Does it create pins in HAL like a real sserial node?

I started on that and needed to modify the code for strm32 - I didn't get it to work yet as I ran out of time for it.
Do you have code edits you could share?

Yes, it creates HAL pins. SSerial card tels LINUXCNC which data will be send/receive and LCNC create pins.
You can define read/write, size for each type in bits (8 bits are 256 steps) and min max value (IEEE-754). maximal 96 bits in and 96 out.
for type encoder are creates some parameters like scale automaticaly.....
you can add special parameters yourself, this value is not transfered in data packet but by address when changed (now I canot remember how).

Yes I can,
Tomorrow on work. I can make simpliest example. send 1 bit to sserial card stm32f103c8 bluepill and turn on/off led and 1 bit back with led status.
Now I am working on versatile template, where will be possible to do select types from predefined lines and program makes everything itself. calculete PTOC, create variables etc. Of course except for HW pin operation.
