I'm using a PIC18F97J94. I'm trying to get the ADC to continuously scan
AN0 through AN12. It appears it scans once and stops.

http://ww1.microchip.com/downloads/en/DeviceDoc/30575A.pdf#page=3D480 shows
a sequence to autoscan all inputs. I'm seeing the ADIF flag being set, but
can't tell if I'm supposed to do something to start scanning again from
AN0. I'm not using an interrupt. My code is just accessing the results
directly in the "per channel" buffer.

Any ideas what I'm doing wrong?

My ADC initialization code is below.

THANKS!

Harold



ADCON1Hbits.MODE12=3D1;     // 12 bit results
                          // Uses Vdd and Vss as reference by default
  ADCON3Hbits.ADRC=3D1;     // Use RC clock for ADC
  ADCON3Hbits.PUMPEN=3D1;      // enalbe charge pump for switches
  ADCON3Hbits.SAMC=3D31;       // longest sample time
  ANCON2bits.ANSEL13=3D0;   // AN13 is digital
  ANCON2bits.ANSEL14=3D0;
  ANCON2bits.ANSEL15=3D0;
  ANCON3=3D0;               // all the rest of the adc inputs are digital
                          // Default channel select for mux A is positive
on AN0, negative on Vss
  ADCSS0H=3D0x1f;       // Scan AN12 - AN8
  ADCSS0L=3D0xff;       // Scan AN7 - AN0
  ADCON2Hbits.BUFREGEN=3D1;  // Put results in scanned regesters
  ADCON2Hbits.CSCNA=3D1;    //Scan inputs
  ADCON2Lbits.SMPI=3D12;    // ADIF goes high after every 13 samples (13
channels)
  ADCON2Lbits.BUFM=3D0;    // single 26 position buffer
  ADCON5Hbits.ASENA=3D1;    // auto scan
  ADCON1Lbits.ASAM=3D1;   // Auto sample. Start a new conversion on
completing one.
  ADCON1Lbits.SSRC=3D7;   // More of autoconvert
  ADON=3D1;             // Start ADC
  ADCON1Lbits.SAMP=3D1;   // start sampling
