Are there any macro pads that can be programmed via a text file stored onboard?
I am wanting a macro pad for work, but we are not allowed to install software on them and even the websites we have access to is limited. I don't want to have to use my personal computer or take the pad home whenever I want to make a more complex macro and am wondering if there are any where the keys can be configured using a configuration file stored onboard?
I think https://github.com/KMKfw/kmk_firmware might be what you are looking for: It exposes itself as flash drive in bootloader-mode and the files on there are just regular Python scripts. If you search for "KMK macro pad", you'll find a bunch of projects - most of them diy.
If you want to start from scratch, Jan Lunge created an awesome tool for setup and keymap adjustments (video https://www.youtube.com/watch?v=RtYJYFMWjNM, repo https://github.com/JanLunge/pog) - with the idea being that after setup you do not need the tool anymore to adjust the keymap.
