LCD with PIC 18f4520 on PICDEM 2 PLUS demo board
PostPosted: Fri Feb 27, 2009 12:32 pm     Reply with quote
I'm tring to get the lcd screen to work using a pic 18f4520 on the PICDEM 2 PLUS demo board.
Here's my code
Code:
#define LCD_ENABLE_PIN PIN_A2
#define LCD_RS_PIN PIN_A1
#define LCD_RW_PIN PIN_A3
#define LCD_TYPE 2
#define LCD_TRIS_LOCATION TRISD
#include <lcd.c>

void main()
{
   lcd_init();

   setup_adc_ports(NO_ANALOGS|VSS_VDD);
   setup_adc(ADC_OFF|ADC_TAD_MUL_0);
   setup_psp(PSP_DISABLED);
   setup_spi(SPI_SS_DISABLED);
   setup_wdt(WDT_OFF);
   setup_timer_0(RTCC_INTERNAL);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_comparator(NC_NC_NC_NC);
   setup_vref(FALSE);
   setup_oscillator(OSC_4MHZ|OSC_TIMER1|OSC_31250|OSC_PLL_OFF);

   lcd_putc("\fReady..\n");

}


What's my problem!?

Which version of the PicDem2-Plus do you have ?

The new Rohs version looks like this. It has silver pads in the bottom of
the prototyping area on the right side of the board:

The older non-Rohs version doesn't have that. It looks like this:

If you have the Rohs version (or the non-Rohs version), then see the
following link. It has code for an lcd driver, and also tells how to make
it work if you have the "Rohs" version of the PicDem2-Plus board.
