Need help to rotate matrix

Post by Sammysa »

Hello,
We are working on a pong clock we are using this code https://www.dropbox.com/s/bqj4b4d0ubl2a ... 3.zip?dl=0 inspired by this project https://123led.BANNED.com/about/.
But when we are using this code the 8*8 matrices are all out of order, rotated and backwards. We are using https://www.adafruit.com/product/555 this matrix. Do you have any idea on how we can fix this. Or just how to flipped by 90 degree each 8*8 matrix.

Does the example code here run OK?
https://learn.adafruit.com/16x24-led-matrix
Can't see the dropbox code, but I managed to find out what had to be in the banned position to read the tutorial you used. It does not use the Adafruit panel, so the arrangement of matrix elements may be different.

No idea or this clock is to be built in multiple instances, or that you just bought stuff for 1, but for clocks like this I seriously recommend using HUB75 panels. They are cheaper, make no noise (you can get nuts from 8x8 LED matrix PWM drivers), better aligned, have a greater variety of drivers making daisychaining/rotation/layout settings easier and they do full RGB.
