DIY Smart LED Light Strip for my 2 seater sofa

Guess I just turned my 2-seater sofa into a gaming one.

Bluetooth speakers and headphones often need more than the chip's built-in resources. The JL JieLi AC696N's SPI interface allows you to add external Flash, an LCD display, and RGB LEDs.

All these configurations can be validated on the AC696N development board before porting to custom hardware. Once working, they significantly expand the capabilities of your audio product.

I have put the gate LED rings on Tindie now.

Sorry about the cost - the LEDs are cheap but there are 552 on each board... #WS2812 style, 3.3V to 5V.

3D models for the gate are on @Codeberg, as are @kicad PCBs to order yourself. All #opensource

What is crazy is moving to the larger LEDs (1.5mm x 1.6mm) from the smaller (1x1mm) actually allows me to do more LEDs in some cases as I can fit vias under the LEDs. It also helps moving the caps to 0201.

This used to be 88 LEDs, and is now 101 LEDs, in a 32mm ⌀ PCB (designed for IronMan gloves, believe it or not!).

The serial LED strip stuff on ESP IDF is pretty good, a standard library. e.g. neopixel, etc.

It used RMT (IR Remote Control) to generate the series of pulses.

But a better way is to use SPI. And the library now does that too.

But I wanted something the library does not do.

Ability to have a strip that is, say, RGB, linked to another that is RGBW. Send 3 bytes for first X pixels and 4 for the rest, etc.

So, ended up making my own SPI based serial LED driver.

Yay, it works.

in case you're still using those, read my rant on this flavour of addressable RGB LEDs, an why I prefer SPI based #APA102 and #SK9822
