Problem with ATM1602B LCD dsply with S6A0069 controller chip

atm1602b

Greetings. I changed the old HD44780 16x1 display for this one because it has backlight and is 16x2 BUT it has a S6A0069 controller chip.

I researched very much on the net and found they say S6A0069 LCDs displays are compatible with HD44780, so I connected it with the same pinout.

When I turn on the circuit LCD initializes and shows the text "mikroelektronica" for 3 seconds and then start to behave strange displaying random unexpected characters and resetting.

And I have a problem: I can't open the device's datasheet because its apears to be in chinese (and acrobat seems not like me).

I found a datasheet from a similar device from other manufacturer that appears to be the same with the only difference that it has green backlight. But I'm not sure if it's a PIC or LCD display command (or timing) issue.

This is my code a MikroC example

* Project name:
Lcd_Test (Simple demonstration of the LCD Library functions)
* Copyright:
(c) Mikroelektronika, 2005.
* Description:
This is a simple demonstration of LCD library functions. LCD is first
initialized (PORTC, 4-bit data interface, default pin settings), then some
text is written at the first row.
* Test configuration:
MCU: PIC16F877A
Dev.Board: EasyPIC4
Oscillator: XT, 04.0000 MHz
Ext. Modules: LCD 2x16
SW: mikroC v6.0
* NOTES:
None.

char *text = "mikroElektronika";
unsigned int numero = 0;

void main() {
Delay_ms(100);
LCD_Init(&PORTC); // Initialize LCD connected to PORTC

LCD_Cmd(LCD_CLEAR); // Clear display
LCD_Cmd(LCD_CURSOR_OFF); // Turn cursor off
LCD_Out(1,1, text); // Print text to LCD, 1st row, 1st column
Delay_ms(2500);
LCD_Out(2,1,"TEST"); // Print text to LCD, 2nd row, 1st column
Delay_ms(2000);
LCD_Cmd(LCD_CLEAR);
while (1){ // This loop prints a counter number for checking display changes
numero++;
LCD_Out(1,1,numero);
Delay_ms(1000);
if (numero = 1000) numero = 0;
}

}//~!

I wonder if this problem is a LCD timing issue ¿?¿?
Any suggestions??

Thanks!!!
