I did the tests in text mode works, in graphical mode I was not able to perform. Does anyone have an example of using graphic mode? |

After reading the datasheet several and several times discovers that the error for use of the graphical mode on the lcd 128x64 drive st7920.
| Code: |
void glcd_update ()
{
int8 v, h;
if (gdram.refresh)
{
for (v = 0; v <YVAL; v ++) // 64
{
if (v <32) // first part
{
glcd_instruction (0x80 | v); // Set Vertical Address.
glcd_instruction (0x80); // Set Horizontal Address.
}
else // second lcd stop
{
glcd_instruction (0x80 | (v - 32)); // Set Vertical Address.
glcd_instruction (0x88); // Set Horizontal Address.
}
for (h = 0; h <XVAL; h ++) // 8
{
glcd_data (gdram.pix [v] [h] .nbyte [1]); // Write High Byte.
glcd_data (gdram.pix [v] [h] .nbyte [0]); // Write Low Byte.
}
}
gdram.refresh = FALSE;
}

Nice ! You should actually post your 'driver code' in the 'Code Library' forum as well. It's a great source of working code!!
