I just got an Arduino Due, and I want to use it as a signal generator. The signal's period is 1500ns, but duty cycle is 80ns/1500ns, I have tried many ways but still didn't work. Could anyone has similar experience give me some help. Since the processor clolck in Due is 84MHz.
I have tried to use direct port modulation, but it takes longer than 80ns to rise up. Can I increase any clcok frequency to get outputs with higher frenquency?
