Backlighting with QMK Firmware, HELP!

Hello, I have a problem creating the backlight configuration.

I have the keyboard with a led for each switch, in total 93 white leds connected to the Pin B5 (not RGB) (TKL + 5 keys)

I would like to have 3 keys to control the LEDs using PWM,
ON / OFF
Increase
Decrease

This is the configuration of my files. (RAR -> https://www.dropbox.com/s/jo00qwws0xrnl ... o.rar?dl=0 )

I'm sure there is useless code for my keyboard, since I use Cluepad as an example.
I had not used QMK, but had TMK for my previous custom keyboard

I press the keys I assigned FN1 FN2 FN3 and there is no answer.

You didn't connect 93 leds to one pin, did you? The micro can't drive that amount of leds itself.

I would need a diagram of how you connected the LEDs

If you can, I've made it work with the maximum amperage that can give me the pin B5, 40mA at 2.7V, but at a low enough, but acceptable brightness.
It was only a test, I would not leave the circuit connected, sure that the teensy burns soon xD

They are 6 parallel lines, each led with a resistance of 330ohm, work perfectly, and through TMK I have managed to control them, but only turn it on and off, nothing to increase or decrease brightness, so I am trying with QMK, which has more examples controlled by PWM.

I want to do it through PWM because to maximum brightness, the LEDs demand 470mA, and controlling them by PWM its consumption would lower to 1/3 - 1/4, but besides that, I do not want to have them to maximum brightness, because it becomes annoying, the I want to put with very little shine.
With the brightness they gave giving 40mA would be happy.

I will also put a 2N2222A transistor, thus boosting the PWM signal.


Sorry for my english of google xD

Or just upload them here, at least they can't disappear then while the post remains.
