Neopixel WS2812 RGB LED (part 1) | RP2350 Tutorial #10

Driving Neopixel WS2812 addressable RGB LEDs using a RP2350. We will implement a PIO state machine to take care of the timing. We will also demonstrate how efficiency can be increased by offloading the data transfer to DMA.

Управление освещением с помощью любого USB пульта по Modbus RTU

Добрый день коллеги. Я думаю многие, кто читает эту статью, сталкивались с проблемой найти визуально красивый пульт для управления основными функциями в системах автоматизации. Несколько дней поизучав дизайн zigbee пультов и радио канальных брелоков я наткнулся на интересный сегмент недорогих USB пультов от 500р, которые все обошли стороной. Поговорим подробнее как их можно внедрить в системы управления не только презентациями, но и чем угодно, начиная от ламп и штор в "умном доме" заканчивая управлением станками.

Got the start of an #ARGB #WS2812 signal parser working using #RaspberryPi #RP2040 PIO. Going to use this with my #OpenRGB RP2040 ARGB splitter project to send configuration data (LED channel counts) using a standard ARGB controller output. RP2040 PIO is awesome for dealing with high speed serial signals!

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.

This is what happens, if you leave me alone with an #ESP32, a #WS2812 LED-Strip and some time.
I have not yet implemented it to display maintenance times. I believe #UptimeKuma will internally handle that as up and note the maintenance somewhere else, but I'm not fully sure.

Спасаем ARGB: Как я заменил сгоревший китайский хаб на ESP32 с веб-интерфейсом

Год назад я собрал систему с пятью бюджетными ARGB вентиляторами Aigo AR12 с 6-pin разъёмами. В комплекте шёл хаб AR12-2012 — типичная китайская плата с 5 портами для вентилей, SATA питанием и выходом на материнку для синхронизации подсветки. Всё работало. Красиво светилось. Но ровно год . Однажды утром вентиляторы крутились, а подсветка — нет. Хаб умер. Покупать новый за $15-20 не хотелось, тем более что я знал: внутри этих вертушек сидят обычные адресные светодиоды (WS2812/SM16703-совместимые). А раз адресные, значит можно управлять с ESP32 .

I've spent way too much time investigating why my #ws2812 RGB LED strip driven by #esp8266 with #wled firmware is only lighting up roughly half way.

I was checking wiring guides and signal strength, modding the level shifter as per https://wled.discourse.group/t/levelshifter-analysis/11871/12

Before I realized I bought a longer strip (5m) than I was calculating with (3m)...

RFC/thinking out loud: Powering Portable Projects

I want to power several 1m long #ws2812 RGB strips from power bank(s) for not a lot of money. The LED specs say 60 LEDs per meter and 60mA max power draw per LED. That's 3.6A/m (18W at 5V).

Affordable USB-C cables are rated for 3A only. What if I take one of these PD trigger boards (0.8€/pc) to request a higher voltage (e.g. 12V), and then use a small buck converter (also 0.8€/pc) to bring it back to 5V. Supposedly it supports 5A out.
