I am interested to use a P10 DMD dotmatrix display (https://github.com/freetronics/DMD20 to show the data. Is there a display library for Ameba? Thank you.

Hi if you are refering to the dotmatrix and library used in this link

I think there is a good chance you can run this library directly on Ameba since only standard SPI interface is used.

There was a compilation error when I tried the DMD demo. Appears to be coming from TimerOne.

WARNING: library TimerOne claims to run on avr architecture(s) and may be incompatible with your current board which runs on AmebaD architecture(s).

C:\Users\User\Documents\Arduino\libraries\TimerOne/TimerOne.h:48:2: error: ‘TCCR1B’ was not declared in this scope
TCCR1B = _BV(WGM13); // set mode as phase and frequency correct pwm, stop the timer
^~~~~~

This seems to be an incompatibility issue… have to look into the code to know what’s going on
