' Name        : ADC10X2.pbp
' Compiler    : PICBASIC PRO Compiler 2.6
' Assembler   : PM or MPASM
' Target PIC  : 28/40-pin PIC types compatible with LAB-X2 board
' Hardware    : LAB-X2 Experimenter Board
' Oscillator  : 4MHz external crystal
' Keywords    : BUTTON, TOGGLE
' Description : PICBASIC PRO program to read an analog voltage on RA0
' and send the decimal representation of the value on the serial port
' at 2400 baud.  10-bit conversion yields 0-1023 result for 0-5 volt input.

' Define LOADER_USED to allow use of the boot loader.
' This will not affect normal program operation.
Define LOADER_USED 1

' Define ADCIN parameters
Define ADC_BITS     10  ' Set number of bits in result
Define ADC_CLOCK     3  ' Set clock source (3=rc)
Define ADC_SAMPLEUS 50  ' Set sampling time in uS

adval Var Word          ' Create adval to store result

   TRISA = %11111111    ' Set PORTA to all input
   ADCON1 = %10000010   ' Set PORTA analog and right justify result

mainloop:
   ADCIN 0, adval       ' Read channel 0 to adval
   serout2 PORTC.6,396,["Value: ",DEC adval,13,10] ' Display value
   Pause 100            ' Wait .1 second
   Goto mainloop        ' Do it forever
