The 3733 is not compatible to the 3731/3732. It uses slightly different registers to store the led enable and PWM values. So there are at last some changes needed for the code writing the PWM values to the 3733. AFAIK there is until now no firmware supporting the 3733. I started to writing some cod...

LED Driver QMK Help

I'm making a custom RGB keyboard, and I'm very confused on the firmware. I'm going to use QMK. It's going to use the IS31FL3733. How would I implement the driver into the firmware? I haven't ever touched QMK, so I'm completely inexperienced. I'm using the ATMEGA32U4.

Connecter Choices?

For my RGB keyboard, I need a 12 pin connector to connect two sides. Do you guys know of any connectors that would be the best at this? I was wondering if there is anything smaller than USB C that would work for me?

For my PCB with RGB LED support, I plan to use throug-hole-LEDs like those available from Zeal PC (https://zealpc.net/collections/accessories/products/4-pin-rgb-led-through-hole). They have 4 pins, a common anode, and a cathode for each color. That is the same pinout as for the smd RGB LED from the...

Looks like LEDs with common anode. Should be no problem to wire them as in the documentation. Just think of the one VCC pin as three pins. You can have a look at this schema: https://github.com/anorak-47/keyboard_pbc/tree/master/anorak_91tkl It uses an 31FL3733 and 4-pin LEDs. Beware, it is complet...

RGB LED PCB Help

So, I want to use a LED driver with RGB LEDs, and I want to use SMD RGB LEDs that only have four pins. They have a R pin, a G pin, a B pin, and a VCC pin. The driver I'm going to use uses Charlieplexing, and I'm confused on how to Charlieplex with single pins. I figured out to do it if you have two ...

OK. I saw on Geekhack that you just want to backlit 40 keys. What kind of LEDs have you found? They must fit inside or below (SMD) the switch you want to use. Most full-spectrum (...) LEDs are RGB, not RGBW. Red, green and blue together makes white. That would be 40×3 = 120 LEDs. LEDs are usually n...

It seems that you are correct on this. I thought that the kinetis SDK would allow for a 'battery charging' device to be developed regardless of the MCU used, but it seems that that specific service is not allowed for MKL2X devices. The USB2.0 battery charging service would have allowed for 1,5A cur...

Okay, thanks. USB-A wasn't a mistake. I wanted to use USB-C, but it's confusing to even do 2.0 on a controller. I'll try to do USB-C 2.0. Do you have any recommendations on which model to use?

You probably choose the colour and formfactor yourself, after that choose an efficient one, so you don't need too much power to drive them. As for wiring: a PWM output will drive a mosfet, through which you can supply enough current for all the leds. You will probably pair each led with a resistor ...

LOL please do your homework HeroXLaser. There is no 1000mAh limit on USB. Where did you get this? mAh is a CAPACITY and not a CURRENT. The number 1000mA is super random, too! If there is any universal value for USB, it is 500mA! Only USB 3.0 and up supports higher current draw (900mA, 1.5A or even ...
