I bought a couple of Adafruit Mini 0.7" 8x8 LED Matrix w/I2C Backpack – Pimoroni and they work fine BUT when I try to take a picture or a video it seems I can’t have all the LEDs displayed. Seems like a very slow multiplexing (but fast enough for the eye).
Here’s a picture of one led matrix with every pixel ON.
I’m using a Pi Zero and Python (but tried a C implementation and it was the same).
Is this due to the HT16K33 driver ? (but I saw video of LED matrix with this driver that were not flickering).
Thanks a lot !
