VDAC PSOC 63

[Anonymous]

Hello together

I can't get any further with VDAC from PSOC 63. With the "Update Mode = Buffered write" everything works, but with the "Direct write" mode I have no output voltage. For the buffered mode I use "VDAC_SetValueBuffered(4095);", for the direct mode "VDAC_SetValue(4095);".

I adapted the VDAC component according to the instructions.

Where do I make the error?

Greetings Franz

Hello Franz,

Looks like the SetValue() API requires some delay before you can call it again (ideally 1 or 2 Peri clock cycles to update the value to the CTDAC). I tried with a CyDelayUs(1) and it worked (attached project).
