Debugging realtime components in UBC3 [01379554481]
Here's how to run the debugger on realtime code in the "unified-build-candidate3" branch from linuxcnc.org. This assumes you are using a run-in-place tree with a userspace realtime model, and that you understand the basics of gdb.

Using Adafruit Macropad as LinuxCNC Control Pendant [01629313423]
Update, 2021-09-25: For compatibility with CircuitPython 7.0.0
CircuitPython recently gained the power to have custom USB descriptors.
With these, we can define a USB HID device that will work with LinuxCNC's
hal_input.
For instance, the Adafruit
Macropad has a (very coarse, just 20 detents/revolution) encoder, 12 keyswitch
positions, and an OLED screen.
The two pieces of software below, when placed in the CIRCUITPY drive as boot.py
and code.py configure it for use with hal_input, using a halcmd line similar to
loadusr -W hal_input Macropad. I haven't actually done the
work of hooking it all the way up to Touchy yet, but it causes all the buttons
& the encoder to appear in halcmd show pin.
This is just the device I picked first; there's nothing to prevent you from
hooking up more exotic things like voltage/temperature monitors through added
CircuitPython code. Addition of output reports for status indicators is left
for the motivated reader.
