' in variable AD_Res.

PORTD = Lo(AD_Res) ' Display lower byte of result on PORTD

Delay_ms(500) ' 500 ms pause

goto eloop ' Repeat all

end. ' End of program

As one port is insufficient, we can use LCD for displaying all 10 bits of result. Connection scheme is below and the

appropriate program follows. For more information on LCD routines, check Chapter 5.2: Library Routines.

program ADC_on_LCD

dim AD_Res as word

dim dummyCh as char[6]

main:

TRISA = %1111111 ' PORTA is input

TRISB = 0 ' PORTB is output (for LCD)

ADCON1 = %10000010 ' PORTA is in analog mode,

' 0 and 5V are referent voltage values,
