    this code works but if you change the input port of the a/d convertor and then add a pause in the line between changing and a/d conversions start then it stucks.

    example:

    Code:
    'retrieve sound level
ADCON0.5 = 0
ADCON0.4 = 0
ADCON0.3 = 0
pause 50
AD_Progress = 1
while AD_Progress = 1: wend
Sound_Level.lowbyte = ADRESL
Sound_Level.highbyte = ADRESH

'retrieve negative level
ADCON0.5 = 0
ADCON0.4 = 0
ADCON0.3 = 1
pause 50
AD_Progress = 1
while AD_Progress = 1: wend
Negative_Voltage.lowbyte = ADRESL
Negative_Voltage.highbyte = ADRESH

'retrieve positieve level
ADCON0.5 = 0
ADCON0.4 = 1
ADCON0.3 = 0
pause 50
AD_Progress = 1
while AD_Progress = 1: wend
Positive_Voltage.lowbyte = ADRESL
Positive_Voltage.highbyte = ADRESH
