RGBW cafe lights with TM1814 chips 🌈💡✨
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
Through CircuitPython examples, learn about the capabilities of the RP2040's Programmable Input/Output block (PIO).
Make us think - we should craft a NeoPixel signal shifter board with an optional inverted output! Coming soon!
