LCD back-light on, but text no display on LCD

Post by tvnaidu » Thu Nov 05, 2009 5:19 am

I have serial UART TXD line connected to EDE702, then LCD MOP-162A connected to EDE702. I am able to turn on back-light with below fisrt two lines, next few lines to display text on LCD, but text not displaying on LCD, can I get some sample code or how can I debug this?. thanks for help.


//turn on backlight
uart_putc(1, 254);
uart_putc(1, 253);


//display text
uart_putc(1, 254);
uart_putc(1, 1);
uart_puts(1, "HELLO WORLD");


//2nd line on LCD
uart_putc(1, 0xFE);
uart_putc(1, 0xC0));
uart_puts(1, "2ND LINE DISPLAY");

I suggest you contact E-LAB Digital Engineering for support on their chip, we cannot help you with this.
