 Bigger Bigger  Smaller Smaller  Reset Reset

Hello, my name is Flo and I'm building a 32x32 LED pixel display using RGB pixels with IC/TM1903 chip and as LED pixel controller I have the T-4000S. Until now all is clear  smiley . Beside preconfigured animation I want to display sensor data (temperature, humidity, time, date, etc.) does anybody know how could I accomplish this?
P.S. I have attached a picture of the T-4000S controller
Thank you in advance for your advice

The T4000 appears to be a self-contained unit, there is not really a way to control it via Arduino.

The TM1903 appears to be an LED driver chip similar to WS2811, but without a datasheet for TM1903 it's hard to tell (I didn't find one).

Hooking up a scope to the output of the T4000 might give you some clues.

Ah, so of course FastLED is *the* library for driving LEDs. https://github.com/FastLED/FastLED

It already supports 1903 driver chips so it should be a simple matter of wiring, no scope required!

yes, of course, I've tried that allready, just for fun. I have made a small 16x16 led pannel to test with Arduino. One question though: is Arduino fast enough to drive a 32x32 led pannel at 24 fps? and besides writing and simple animation I don't know much on the Arduino  smiley-confuse (that's mainly why I bought a controller)
Thank you for your support
