RGBW cafe lights with TM1814 chips 🌈💡✨

What this episode covers

More! We got a set of weatherproof cafe lights with RGBW LEDs for a 'pure' white color light. However, they don't use the WS281x chipset for the control signal. Instead, it's TM1814, which is kind of similar but has a few key differences. One is you have to send an 8-byte 'global brightness' setting to start, and then you have to continuously send a signal over every 400ms, and to top it off, the signal is inverted! After some PIO twiddling, we did get them working pretty nicely with an RP2040 https://learn.adafruit.com/intro-to-rp2040-pio-with-circuitpython/using-pio-to-drive-a-neopixel Make us think - we should craft a NeoPixel signal shifter board with an optional inverted output!
