Question about keyboard for cnc build

Well, the Python API would appear to have most of the functions that are on the keyboard - so a listening loop etc, would seem to be the solution... Some logic for the key being pressed down, so you can use modifiers (if even needed).

So no point of a pipe, just a Python script listening and sending API calls...

Okay, we'll found the LED commands. Just mashed the keyboard and copied/pasted blocks of ASCII characters until they went on, and then did the same until they went off, and kept narrowing it down...

you can go for a SILIKON Keyboard as it can be clued to the machine itself

Kind of the point here is to use something that is already made for the purpose, and designed to control the machine itself?

Hi Andy,

Thanks for that...

Reading the docs, I'm genuinely confused how I would map any data coming in from the keyboard using the matrix_kb component?

I've been having a look at HAL_INPUT, and that seem to be the way to go. I just have to coerce the serial keyboard into being a Linux input device - I'm trying to figure out how to have a serial keyboard treated as an input device.

So,would seem to be the solution there. I need to have a play around and see what inbuilt keyboard types will work.

I've also been looking for a serial to USB HID device... That should just convert anything coming by serial into keypresses.

Can out get physical access to the row\col of the keyboard matrix ? if so a 7i73 could be the answer if you are going the MESA route of a custom USB solution, Arduino ProMicro or another mcu that has native USB.
Or as per your solution an MCU reading the serial and connecting via USB.

Any pics of the guts of the device ?

on ebay there are many controll panels for CNc machines and manufactuers lke HAAS VF serias use a USB compatible keyboard
that can be connected to a COMP

Huh?

Kind of defeats the objective of using EXISTING hardware don't you think? Or should I just replace the CNC machine with a new machine as well, and stop using LinuxCNC, and use a Fanuc controller?
