electry / arduino_sk6812 Goto Github PK

Hi there, How do I set the brighness?
Thanks!

Hello,

I am currently doing a project and I want to use SK6812 LEDs.
The main chip of the project will be an ESP32.
Does this program also run on an ESP32 when I use a logic level shifter to boost the signal to 5V?
If not I will have to use an ATMEGA328P chip talking to the ESP32 over a serial connection.

Hi Im having the following error when trying to upload the example code.

Please help.

The SK6812 controller awaits a ~80μs low signal between data transmission.
Taken from: https://cdn-shop.adafruit.com/product-files/1138/SK6812+LED+datasheet+.pdf

Currently, if we run the sync() funciton in an endless loop, the leds light up in same "random" fashion.
This is because we do not wait those 80us between sending out the signals.

Adafruit does some busy wait for 300us to guarantee proper led setting.
Same logic should be applied here.

in sendarray_mask functions in line 72 there is a ban on interrupts, I don’t see where the permission is ...
or is it not necessary?
