I want to make a triangular waveform for sine modulation. I made high frequency PWM. Sine modulating need high frequency triangular wave. When I searched, I couldn't see how to make a high-frequency triangular wave. [But i got 100Khz PWM in forum. :slight_smile: ] Do you know how to code it?

In MEGA 2560, making triangular waves over 300kHz

I'm pretty sure making any decent triangular wave is beyond the Mega's capability without additional hardware.
