TFT01 LCD Drive Controller Initialization

TFT01 LCD Drive Controller Initialization

TFT01 series LCD modules there are 3 kind of sizes. They are 2.4"(RGB 320 x 240), 3.2"(RGB 320 x 240???/strong>and 3.2w"(RGB 400 x 240). Each of it has separate drive controller.  We conclude that each of the drive, for user-friendly reference. 2.4"(RGB 320 x 240), used a controller ILI9325, it’s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. Note the Address_set() function is different each other, which setting X/Y coordinates. The initial function as follows:

[cce_cpp]
void Address_set(unsigned int x1,unsigned int y1,unsigned int x2,unsigned int y2)
{
      Lcd_Write_Com(0x00,0x20);
      Lcd_Write_Data(x1>>8,x1);	  //Setting X
