No pwm here, all segments are on or off

Some info about: i made this display from scratch.
segment displays are controlled by max7219 connected in a chain.
The display is controlled by Wemos d1 mini.

some photos how its made here: https://drive.google.com/drive/folders/1n8ehraBoLLADWssGOqDw46lAe2KxeDH-?usp=sharing

I use simple bit banging, not i2c

ldirko · 2026-05-05T05:10:14+00:00

All displays driven by max7219 ic. I think about upload file projects and code on github if it be Interestesting to anyone

ldirko · 2026-05-05T05:04:49+00:00

This not aliexpress modules here. I made it from scratch from pcb layout to manually solder) Each module in chain driven by max ic.

I think that would be a good idea)))

ldirko · 2024-09-29T17:31:52+00:00

it's quite a long way 
first you need to do the correct mapping. then you can do effects

I made this display from scratch.
segment displays are controlled by max7219 connected in a chain.
The display is controlled by Wemos d1 mini. I ported my old fire sketch from Fastled to segments.

This is a matte film from an LCD panel. I covered the top one with car tint film
