do you need all the project will work in 12 bits?what I am not sure the capacitor should be located there..maybe before the opamp,what about the main.c did you manage to read properly?
I had a working project with VDAC8 and I changed it to DVDAC because I want all the project to work with 12 bit resolution
I changed in the main.c but I think I have a configuration issue there(how to read in the right way 12 bits)
I didnt know about the capacitor because I have to use an opamp I tries before and after the opamp but didnt work
also I had a look at the example project but didn't have enough info
do you know someone that can have a look and tell me what is no t defined well in the project for 12 bits(main.c and schematics)?
thanks a lot
Yes, the cap should be at the output of the DVDAC. before OpAmp,
so add a pin to bring that connection out.
Also in your code you have the OpAmp_Start() commented out, so
that OpAmp is off ?

Thanks a lot I will try it and let you know..
Note set OpAmp properties to high power.
Thank a lot again !!
unfortunately I tried to take a pin out and to put a 10nF capacitor to grownd , I took off the comments from the Opamp as you said
but I still dont get the results
what do you think is the reason?
1.code( I added a comment to what I changed for DVDAC)
2.definition of components?(I need 10 K samples per secons and 12 bit resolution)( the DeltaSigma was defined to 12 and to 8 but with no success)
3. the kit?(It is new so I guess it is nor the problem)
4.pin assignments is not ok
attached the modified project kindly your help
