Very nice! Switching to the ESP32 was frustrating, but well worth the trouble. I just use the ESP32 DevKit C and Pico. Can't beat it for $10, and it has built in USB. I designed my own clone of the DevKit C to play around with reflow, but the parts cost was around $14 so not a good value proposition.
The .8" displays use 1 LED per segment, and all segments appear to be lit evenly without using different values for current limiting resistors. I use the HT16K33 so no resistors are necessary, and lighting is very even. The 2.3" displays are a different story. Some segments use two LEDs, and the longer ones use four. A 5v supply won't work, and the HT16K33 can't supply enough current to run them. On Sunday, November 3, 2019 at 4:00:00 PM UTC-5, newxito wrote: > > Nice clocks!
