12f675 A/d Miseries

[mystified]

I thank you of your time
The code
define adc_bits 10 'adc settings
define adc_clock 3 ' adc setting
define adc_sampleus 50 'adc setting

should set up the a the analog to digital converters (adc)
the output from the adc converter should be 0 to 1023
but i get just 0 to 3
I will work on the sound after I can get the 0 to 1023to work.

Take a look at this informative thread by Melanie.

cannot find clock 3 in datasheet it now works thank you

OK , I put clock back to 3 but used upper chase in the define statement and that is what made it work
Thank You very much.

See any similarity between DEFINE ADC_CLOCK 3 and bits 6 thru 4 of ANSEL?
