#105980 - Why not PWM? Responding to: ???'s previous message |
Hi Guven
Assuming your MCU has on-chip PWM, and your desired triangle waveform upper limit is less than several kilohertz, then you could do it with a PWM update routine. With this setup, however, your biggest problem isn't the 'schematic' (op-amp buffer / RC low pass filter), it is the software! Cheers, Valentin |
