Hello.

I have a question about slope campensation in TIDM-02000.

I can set RAMPMAXREF value.

But I can not see slope operation.

Can I see slope waveform using oscilloscope?

Thanks,

Sangmo Kim.

Ramp operation is not visible on scope. The slope is the internal DAC value that is used by the comparator. You can find more details about the ramp generator in the MCU technical reference manual.
