I thought [setup_adc_ports(sAN0|VSS_VDD);] would have set ANSEL to 0x01 but it doesn't. Armed with this knowledge all I should have to do is make sure I manually set ANSEL.

Thanks

I tested the code with my hardware and I get the same results as before (ANSELA remains at POR value).

The manual register select code work as expected.

Thanks
Brian

Thanks for the reply I'll test it out. In the mean time I have the program working using manual setting of registers and testing / toggling the GO/DONE bit.

#byte ANSELA = 0xf38
#byte ANSELB = 0x ...

Thanks! Can I also define CONFIG3H in the same way? It's address is huge (300005h). I would like to clear bit #1 (PBADEN) in this register so the portB a/d's are disabled upon POR.

Thanks
Brian

Still no luck getting the adc to work. The ANSELA value never changes from the default POR setting (00101111b) even after the following lines execute:

setup_adc(ADC_CLOCK_INTERNAL);
setup_ad ...

Thanks Guys for the replies!
I'll check out the code early tomorrow.

P.S.
My version is 4.110

Thanks again

Thanks for the reply. I tried looking at the header file and I'm able to get the program to compile. The trouble is I'm not getting the results I would expect. I select the an0 port only as follow ...

I am having trouble setting up the a/d on a 18f26k22. I need to read a 10bit value from an0 only using vss/vdd as references. I have successfully configured other pics for a/d. The application is n ...

Where is the compiler getting its' part specific memory size. Is this pulled from the top part of the header file? I did notice that the ram size was stated as 512. I changed it to 3896 as stated i ...

Sorry I forgot to add the compiler states 3%
The output from the printf is "ROM size is: 1cc0"

The memory usage gauge reads 121 bytes using version 4.111

I had a working program before I switched processors from a 18f2550 (32k flash) to a 18f26k22 (64k flash). Even though the memory size doubled I get the following error:

Executing: "C:\Progr ...

I am having a problem understanding why my 18F2550 processor will not change port A pin states properly. PIN_A4 will not change using output_low(PIN_A4) or output_bit(PIN_A4, 0). The same is true if ...
