I like to set a project with a Teensy 3.5, two 64 x 32 RGB-Panels and the Teensy Audio Shield. We want to use the Display to play text and play a song over the audio shield in order to use it for karaoke.

I achieved to use the displays as 64 x 64 and the audio shield for themselves. I canít use them simultaneously because they are sharing seven pins.

In order to solve that problem I like to change the pins used by the SmartMatrix library to unused pins on the teensy 3.5 (unused PWM-Pins are 29-30 and 35-38). Unfortunately the pin assingment (GPIO_PIN_XX_TEENSY_PIN) in MatrixHardware_KitV1.h seems to have no effect. I already aksed in the SmartMatrix forum, but they told me to ask here for support in changing the pins.

Has someone else used this combination or does someone know how to change the pin assignment?

Kind regards
