Hi everyone, I'm sorry to post this question here, but I'm really stuck and I can not get any display to my LCD. I'm trying to read data from an Rfid module using Pic18F4550. Here is the code I'm using Include "modedefs.bas" ' Include serial modes
asm
__CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
;__CONFIG _CONFIG1L, _PLLDIV_2_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
__CONFIG _CONFIG1H, _FOSC_XTPLL_XT_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
; ; ; Oscillator Switchover mode disabled
; ; Fail-Safe Clock Monitor disabled
; XT oscillator, PLL enabled, XT used by USB
__CONFIG _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L & _BORV_2_2L & _VREGEN_ON_2L
__CONFIG _CONFIG2H, _WDT_OFF_2H
__CONFIG _CONFIG3H, _MCLRE_ON_3H & _LPT1OSC_OFF_3H & _PBADEN_OFF_3H & _CCP2MX_ON_3H
__CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _ICPRT_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L
endasm
DEFINE OSC 48
DEFINE LCD_DREG PORTB
DEFINE LCD_DBIT 0
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 5
DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 4
DEFINE LCD_BITS 4
DEFINE LCD_LINES 2
DEFINE LCD_COMMANDUS 2000
DEFINE LCD_DATAUS 50
PAUSE 100
TRISB.7=1
A0 var PORTB.7
DataRec Var byte
loop1:
Serin A0,T9600,DataRec
Lcdout $fe, 1 ' Clear screen
Lcdout "V: ", DataRec
pause 500
goto loop1 I hope you can help me. thanks, microbox

I don't think think that PortB can be used for serial com
try this
TRISC.7=1
A0 var PORTC.7
I don't use PBP and there is just a slight defference between PDS and PBP
