Slow analog output DAC low voltage
Posted: Thu Mar 31, 2022 4:15 pm
I'm using the C API to set the analog output AO0 to 1.8V.
The API (rp_AOpinSetValue(0,1.8)) returns true but the output is actually 1.1V.
When I try to set a lower voltage: 0.9V on the output i get ~0.6V.
I've measured the AO0 pin with an oscilloscope.
Has anyone exeperienced this, in the documentation is clearly amrked that I can set it up to 1.8V.
Thanks
