Advice - QMK, Arduino + FastLED
« on: Sun, 25 June 2017, 12:23:47 »
Hi,

I need some help starting out please - my question is how can I set up or is it even possible to use QMK firmware and arduino libraries together?

I have a teensy 2++ that is going to drive a custom hand wired keyboard layout, reading the forums QMK firmware looks like a good choice for handling the RBG cherry switches?

What I wanted to know is how can I include calls to the board? Sorry if this is dumb but in the arduino IDE I can hook up a potentiometer and then call analogRead(A0).

I was hoping I could then add some WS2818B leds for some dynamic backlighting utilising FastLED and then change the hue using the value from the above call?

Is this even remotely possible?

I would really appreciate any guidance - I am okay with programming (.Net dev) but this is my first DIY and I am totally unfamiliar with the environment.

I have downloaded Arduino along with Teensyduino and have plugged away at a breadboard. C:\program files (x86)\Arduino  this seems all good - my next port of call was how to drive the switches and QMK looks just what I need (Macros, layers, etc) so I've installed bash/git on my Windows 10 pc and downloaded: QMK to C:\firmware\qmk_firmware.

But now I am at a loss and before I start wiring, just where to begin and avoid a cluster ....  so any advice would be greatly appreciated. Going plate mount, hand wired all the accessories on hand.

Should I even use QMK and instead use the bounce library (Seems very very limited - no macros, layers).

Sorry for all the questions - if you know even an answer to one part please I would be happy to hear your thoughts.

Thanks for reading this post

bump. I would also love to know if we can combine QMK and FastLED

I can't help you but the folks who make the Teensy have this to say.

Is FastLED some additional LED controlling software to make the LEDs do fancy things, because QMK can control WS2812 LEDs just fine, "out of the box".   I suspect you should be able to get QMK to run on the AT90... I got it to run on the ATmega32U2.

I got it working a couple weeks ago on a pro micro.  I think the 200ma is due to voltage drop.  I can push 64 LEDs (amount I plan to use) to 350ma.  Haven't tried pushing it further.
