How to Configure your Drop Keyboard!

Sep 26, 2018

lbee09It's pretty confusing.
https://github.com/Massdrop/qmk_firmware/blob/master/keyboards/massdrop/ctrl/keymaps/default/keymap.c#L152-L167
I've done only a little research, but it seems it has something to do with voltages and how using the extra USB port on the board as a hub work.
based on how you need to actually do FN+CTRL+SHIFT+U and FN+CTRL+SHIFT+I for them to actually work, that's probably a good indication of "be careful".
Reply back if you find out anything else. I'm curious, but I'm curious about more stuff than those.
Edit: Maybe @DarkMio knows?

lbee09Ignore them. It's for debugging the voltage / selection mode on the two USB controllers for passthrough and so on.

DarkMiocan i just overwrite them? same goes for the tg nkro (i dont think ill ever need to press more than 6 buttons at a time) I I had a hell of a time finding a set of caps to match the barebones and they already have secondary layer functions printed on the keys so I'm trying to match those the best i can

MonkofMoneroYeah no problem. Being able to re-re-program them might be a bit tougher, but I seriously doubt you'll ever need them.

LastContinuethank you for telling me what i want to hear! lol

MonkofMonerobut say i did want to use QMK (the real one) to move stuff around on the ctrl and my alt.. is there anything I need to know specifically relating to these boards? I've heard theres a slightly more noob friendly tool for using QMK maybe that could work?

MonkofMoneroIf you mean QMK Toolbox: No it doesn't work for these boards. https://qmk.fm/toolbox/ The chip that powers these boards isn't compatible with any of those. There's really two parts to putting a custom map onto a board with QMK.

Building with QMK (this depends more on your OS than your board. Once you have this setup, you can build for just about any board assuming it supports QMK)
Getting what you built onto your board. This is highly specific to the board itself. For these boards it's mdloader (which I'm assuming you've already gotten working)

https://github.com/LastContinue/ctrl-info/wiki/Alternative-Compile-QMK-Quick-Start-Guide There is a guide I wrote that links to "the right way" of setting up building QMK for your system, as well as a cheater way that I advocate via Docker https://github.com/LastContinue/ctrl-info/wiki/Alternative-Compile-QMK-Quick-Start-Guide Once you get the .bin files it's just like how you would do with mdloader or the drag-n-drop helper I wrote (or whatever else you use)

LastContinueWow thank you! Is there still hope that QMK and the massdrop config are going to merge as they were saying?

MonkofMoneroIt's listed as a "goal" here https://github.com/Massdrop/qmk_firmware/pull/3 . I'm not holding my breath, but I'll be happy if that gets merged (although based on whats in there, I suspect I'll need to redo a bunch of my docs 🤷‍♂️)

DarkMioWhat does GCR actually stand for? I'm having trouble editing led_matrix.c it's obvious it's purely for voltage management but I haven't been able to find what it stands for or whether it actually is a thing outside of MD. EDIT: Stands for "Global Current Register". Apparently it's the register that holds the value (present value I think) for current delivered to the leds (or perhaps the whole board), it's 165 default and has range 0-255. I think the value doesn't actually signify electrical current, it's just an arbitrary value for light intensity. Can find this here. I can't tell if the GCR is for the whole board or just the ISSI3733. I've only found it used in relation to the LEDs which makes me think it's for the two ISSI3733 chips only. Either way, its actual usefulness in modding is that you can control the LED intensity and its default value as well as the value of the step when increasing or decreasing LED intensity. @DarkMio Am I correct? Is there any other useful info about GCR?

Does the ALT v2 PCBA support USB-C e-marked cables?

Currently my ALT v1 does not work with e-marked USB-C cables. I was wondering if the v2 PCBA does support these types of cables (thunderbolt 4 cable for example)?

How do you do per-key RGB lighting on a Shift V2?

I saw the online configurator that lets you do this on the Shift V1, where it spits out a compiled firmware file to flash. The V2 doesn't seem to have this function in the Windows configurator, though. I can't imagine the answer here is "you're going to have to manually write the hex for every key in QMK, compile it, and flash that".
