It look like new star is making a [new LED they are calling NS107S](https://cdn.hackaday.io/files/21293910999712/NS107S%20RGB%20LED%20Chip.pdf). This is an interesting option because the PWM rate is v…

I can't get FastLED to work with the [Beetle ESP32](https://wiki.dfrobot.com/Beetle_ESP32_SKU_DFR0575). I've tried several combinations of I/O pins, supported LED chipsets (APA102, WS2812B), #define F…

Hello, is there any progress on supporting Hardware SPI on ESP32 at least for APA102 strips?
The bitbanging works without any problem, but it is unfortunatelly slow for POV effects.
I tried the NeoP…

The APA102 LED on the shim supports 32 brightness levels. However, we currently always use the maximum brightness level, and dim by lowering the individual RGB values. Due to the gamma, this results i…

My APA102 LEDS have a gamma offsets between the colours. I.e. the leds follow the same brightness curves but they shifted relative to each other. By shifting the curves in the gamma array by 2 or 3 …

As I simply could not find any documentation on this, I'm misusing GItHub issues to ask this question and also suggest documenting this:

Currently, the RGB LED on the board is controlled by the MCP23017 GPIO expander. The expander doesn't support any kind of PWM, so right now it's only possible to show 7 colors on the LED.

Hello David.
So I have hacked apart your lovely application and connected it via USB to an Arduino, connected in turn to a string of LED lights (using the APA102 chips). The idea is that you place …
