Using the PIC18F45Q10 and the ADC is not working in Hardware.
Simulation is fine inside of flowcode.
I had a similar problem with the ADC on the PIC18F25Q10 part.
Hopefully it is a similar solution.

Thanks,
Dave

Can you be more specific?
You mean you can't select FVR?

I have not got to trying FVR yet but I see it in the Drop down.
I expect to need a C code block to select the FVR voltage.

For now I am just doing a simple test to check the ADC functionality.
Reference is Vdd, Pin An19
Just reading a slide pot with "GetInt" and displaying the result on a display.
FlowChart attached.


Thanks,

For a reality check I swapped out the PIC18F45Q10 with a PIC18F45K40
and the ADC works correctly including the FVR register.

The Chips are functionally similar so it looks like there is a real issue with the PIC18F45Q10 part.

Thanks,

Has there been any movement on this issue?

Thanks,

Ben,

Sorry to push ...
Do you know if this issue will be resolved soon?
Should I pick another Chip to develop with or move it to MPLab.

Thanks,
Dave

Hi Dave,

I'll have a look into this for you today and see if I can work out what the problem is.

I've now had a go at making a change that will hopefully allow the ADC to work on the Q10 devices.

Let me know how you get on.

Ben,

Sorry to report things are still not working.
Tried AN1 and AN16
Verified voltage on A/D input pins

A/D Setup
VDD
Fosc/32
40

Thanks,
Dave

Ben,

Any updates on this problem?

Thanks,
Dave
