lcd

i am trying to interface an LCD with a PIC16f887 microcontroller but my lcd is on but not displaying anything. i have crosschecked all my connections several times the code is as shown below.

// LCD module connections
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D4 at RB0_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D7 at RB3_bit;

sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections

void main(){
ANSEL = 0; // Configure AN pins as digital I/O
ANSELH = 0;
Lcd_Init(); // Initialize LCD
Lcd_Cmd(_LCD_CLEAR); // Clear display
Lcd_Cmd(_LCD_CURSOR_OFF); // Cursor off
Lcd_Out(1,1,"seyi");
}

FT812

Hello

I modified FT800 demo code for PIC18F46K22. Work fine FTDI VM800B50A modul... I have FT812 version display. (RVT70AQFFWR00_Rev.1.2 - Riverdi) Also modified, does not work with PIC18F46K22. The problem is that, the display remains dark. (1-2 second backlight, then the dark) This MCU not compatible FT812? Bad FT812 driver board?

I'm sad and I regret that I bought FT812 display. :( i use FT800's display, and no problem with 8bit MCU. FT812 has no specific examples...

I hope someone can tell reassuring. Example with 8bit MCU?

Thank you!

PS:

Sorry for my English.
