Hi,

Anybody had success with Romeo v1.1 board driving a stepper motor?

I saw Angelo's library, but it's only for Romeo V2.

Best regards,

Marcos

As I've posted, I have to change the clock source, leading to 64 times faster. In Romeo v2 the PWM output is relied on Timer3 and Timer4 of the MCU, while in Romeo v1.1 it is based on Timer0. Timer0 is typically used by the library from Arduino, like the function [b]millis()[/b]. If I change the clock source of timer0, function like [b]millis()[/b] will be out of action, which is unacceptable.
