Hi All,
I am hoping I may be able to get some assistance regarding installing a ST7920 controlled 128 x 64 LCD dot matrix screen.
I have been trying to fix this issue for days with no luck!
I have installed the following library into my Arduino IDE - u8glib_arduino_v1.18.1.zip - Success
The following code is one if the examples that came with the u8glib which I am trying to get working:
#include "U8glib.h"
U8GLIB_ST7920_128X64_1X u8g(8, 9, 10, 11, 4, 5, 6, 7, 18, 17, 16); // 8Bit Com: D0..D7: 8,9,10,11,4,5,6,7 en=18, di=17,rw=16
//#define MINI_LOGO
void drawColorBox(void)
{
u8g_uint_t w,h;
u8g_uint_t r, g, b;
w = u8g.getWidth()/32;
h = u8g.getHeight()/8;
for( b = 0; b < 4; b++ )
for( g = 0; g < 8; g++ )
for( r = 0; r < 8; r++ )
{
u8g.setColorIndex((r<<5) | (g<<2) | b );
u8g.drawBox(g*w + b*w*8, r*h, w, h);
}
}
void drawLogo(uint8_t d)
{
#ifdef MINI_LOGO
u8g.setFont(u8g_font_gdr17r);
u8g.drawStr(0+d, 22+d, "U");
u8g.setFont(u8g_font_gdr20n);
u8g.drawStr90(17+d,8+d,"8");
u8g.setFont(u8g_font_gdr17r);
u8g.drawStr(39+d,22+d,"g");
u8g.drawHLine(2+d, 25+d, 34);
u8g.drawVLine(32+d, 22+d, 12);
#else
u8g.setFont(u8g_font_gdr25r);
u8g.drawStr(0+d, 30+d, "U");
u8g.setFont(u8g_font_gdr30n);
u8g.drawStr90(23+d,10+d,"8");
u8g.setFont(u8g_font_gdr25r);
u8g.drawStr(53+d,30+d,"g");
u8g.drawHLine(2+d, 35+d, 47);
u8g.drawVLine(45+d, 32+d, 12);
#endif
}
void drawURL(void)
{
#ifndef MINI_LOGO
u8g.setFont(u8g_font_4x6);
if ( u8g.getHeight() < 59 )
{
u8g.drawStr(53,9,"code.google.com");
u8g.drawStr(77,18,"/p/u8glib");
}
else
{
u8g.drawStr(1,54,"code.google.com/p/u8glib");
}
#endif
}
void draw(void) {
if ( u8g.getMode() == U8G_MODE_R3G3B2 ) {
drawColorBox();
}
u8g.setColorIndex(1);
if ( U8G_MODE_GET_BITS_PER_PIXEL(u8g.getMode()) > 1 ) {
drawLogo(2);
u8g.setColorIndex(2);
drawLogo(1);
u8g.setColorIndex(3);
}
drawLogo(0);
drawURL();
}
void setup(void) {
// flip screen, if required
//u8g.setRot180();
}
void loop(void) {
// picture loop
u8g.firstPage();
do {
draw();
u8g.setColorIndex(1);
} while( u8g.nextPage() );
// rebuild the picture after some delay
delay(200);
}
Unfortunatley everytime I try and compile this code (or any other of the examples) it returns the following error:
In file included from /home/pi/sketchbook/libraries/U8glib/U8glib.h:42:0,
** from U8gLogo.ino:42:**

typedef uint8_t PROGMEM u8g_pgm_uint8_t;

Please submit a full bug report,
with preprocessed source if appropriate.
See http://gcc.gnu.org/bugs.html for instructions.
After days of searching for an answer I am now at a loss. Is there anyone who can help me understand this problem to rectify?
Kind Regards in adavnce
