Posted on January 17, 2015 at 07:03Hi All,
Somehow, I managed to run GUI Driver with GUIDRV_Lin_1 after lots of effort.
GUI_DEVICE_CreateAndLink(GUIDRV_LIN_1, GUICC_1, 0, 0);
LCD_SetSizeEx (0, 144, 128);
LCD_SetVSizeEx(0, 144, 128);
Width = 144 = 128 bit for pixels + 8 bits idle + 8 bits Next Line No.
unsigned short int frameBuffer[1152]; //9 - half words per line , 128 such lines
//Passing framebuffer address to GUI driver to fill drawn image/window.
LCD_SetVRAMAddrEx(0, (void *)frameBuffer);
//To Transfer image from memory to display
LCD_update()
{
int i,j;
unsigned char *p = (unsigned char *)frameBuffer;
LCD_CS_HIGH();
for(i=0;i<=100;i++);
lineno = 1;
LCD_SendByte(MLCD_WR);
LCD_SendByte(lineno);
for ( i=1; i<=128; i++ ) {
/* Send pixels for this line */
for ( j=0; j<18; j++ ) {
LCD_SendByte(*p);
p++;
}
}
for(i=0;i<=100;i++);
LCD_CS_LOW();
}
So whenever i have drawn the image using GUI Driver like calling GUI_DrawBitmap();
I call LCD_Update() function to transfer image to display. Is there any way to attach/glue LCD_Update function to GUI Driver so that whenever i call GUI_Exec() it calls LCD_Update when painting is done in memory.
ST People, please help on this as i am stuck up with this issue.
