Hi Filipe, Thanks for the feedback and good to hear that it works but you are using it outside of its specification since the maximum clock is 40 MHz. I am not sure what the effects will be but correct operation might not be guaranteed.
Did you know there are also PICs that can run on a 64 MHz clock? For example the PIC18F25Q10 but if I am not sure if you can program this one with a PICKit2 or PICKit3, at least not with the standard PICKit3 software.

Later on will test 40MHz (10MHz xtal)... Thank you very much. Cheers Filipe Santos On Wednesday, August 17, 2022 at 6:17:52 PM UTC+1 [email protected] wrote: Hi Filipe, About the ansel error. It seems to be in your program, not in a library so I think you should remove those lines. About the 40 MHz. Do you need 40 MHz using a crystal or is 32 MHz using the internal oscillator sufficient?

Any help here? Thanks Cheers, Filipe Santos.

It was there in 1.4.0 and currently we are at 1.7.0. The problem was that the library was not maintainable anymore so it was removed and the configuration of the channels was moved to the program of the user. Also the use of JANSEL was removed from all device files because of the same reason. So I suggest you download the latest Jallib release and look at one of the adc sample files. They are all updated to incorporate this change. For example, a typical adc set-up in your main program will then look something like this but this is PIC dependent. -- Step 1: ADC analog input pin setup const byte ADC_CHANNEL = 3 -- potmeter connected to pin_AN3 ANSEL_ANS3 = TRUE -- port 3 is analog input (default) pin_AN3_direction = input -- Step 2: Set VDD and VSS as Vref ADCON0_VCFG = FALSE -- Step 3: Use Frc as ADC clock ANSEL_ADCS = 0b011 const ADC_RSOURCE = 4_700 -- Input resistance: 4.7K potmeter -- Now we can include the library include adc -- And initialize the whole with our parameters adc_init() Kind regards, Rob ________________________________ Van: [email protected] <[email protected]> namens flyway38 <[email protected]> Verzonden: dinsdag 16 augustus 2022 17:58 Aan: jallib <[email protected]> Onderwerp: [jallib] PIC18F2580 ADC CHANNELS Hello to all, Am coding for this PIC (18F2580) now.
