help setting up 16F886 for ADC

[mark_s]

I think that the code "adcin3x" is for the old pic16F877, not a pic16f887. The adc in the newer chips have more registers. I have found the adcin command does not always work. So I use a manual set and read routine. Below is an example for 10bit, I think the 8bit result will be in the ADC_AN0.HIGHBYTE when the adc is set to left shift?

ADC_AN0 var WORD '10bit result 
ADC_AN1 var WORD '10bit result

'Read AN0
'--------------------------------------------------------------------------
ADCON0 = %11000011   'Set adc channel = AN0

WHILE ADCON0.1 = 1  'WAIT FOR CONVERSION

    WEND
     ADC_AN0.HIGHBYTE = ADRESH
     ADC_AN0.LOWBYTE  = ADRESL

'Read AN1
'--------------------------------------------------------------------------

ADCON0 = %11000111   'Set adc channel = AN1

While ADCON0.1 = 1  'WAIT FOR CONVERSION

     WEND


     ADC_AN1.HIGHBYTE = ADRESH
     ADC_AN1.LOWBYTE  = ADRESL
'---------------------------------------------------------------------------
