unsupported lcd on avr. #244

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
hi i have wg12232a display, and i'm trying to interface it with atmel studio. 
the problem is that constructor doesn't work, and on supported devices on wiki 
there is n\a under avr.

i'm using this constructor:
U8GLIB_SBN1661_122X32 u8g(d0, d1, d2, d3, d4, d5, d6, d7, cs1, cs2, di, rw );

i know it's not supported, but is there any way to modify arduino library so it 
would work on avr?

BTW: This is code i'm using:

#define F_CPU 8000000UL

#include <avr/io.h>
#include <util/delay.h>
#include "u8g.h"

int main(void)
{
    while(1)
    {
        U8GLIB_SBN1661_122X32 u8g(d0, d1, d2, d3, d4, d5, d6, d7, cs1, cs2, di, rw );

        // picture loop
        u8g.firstPage();
        do {
            draw();
        } while( u8g.nextPage() );

        // rebuild the picture after some delay
        _delay_ms(1000);

    }
}

       void draw(void) {
           // graphic commands to redraw the complete screen should be placed here
           u8g.setFont(u8g_font_unifont);
           u8g.drawStr( 0, 20, "Hello World!");
       }

it might work with the c interfrace:

Modify the aver examples and use u8g_Init8Bit:

uint8_t u8g_Init8Bit(&u8g, &u8g_dev_sbn1661_122x32, uint8_t d0, uint8_t d1, 
uint8_t d2, uint8_t d3, uint8_t d4, uint8_t d5, uint8_t d6, uint8_t d7, uint8_t 
en, uint8_t cs1, uint8_t cs2, uint8_t di, uint8_t rw, uint8_t reset);

thanks. it looks promising but one more thing how do i determine ports.

I know that PN(1,1) stands for port B pin 1 but i need to use port D,C or A 
because port B has all isp pins and they interfere with lcd.

he he. looks like i tried to use arduino syntax. sorry for confusion my bad, oh 
and the code worked ;D

PN(3,1) is port D, pin 1, if this is still a question.
