Hello,
We need two stepwise ramping reference voltages from a PIC micro (as in the attached waveform).
Is this possible?
Originally I was going to do it with analog circuitry so I posted this…………..

..but now we need to do it from a micro….so…….
We need two stepwise ramping (reference) voltages as in the attached. (the ramping is over 200us). One ramp goes up whilst the other simultaneously goes down. The ramps may go up to or down from a level which may not always be the same for every “ramp episode”.
Do you know if its possible to do this from the two DAC outputs of say a PIC16F18856?..or any other PIC micro?
LTspice sim and waveform schem attached.
