    看了楼主贴子,正好需要,赶紧入了一个同类的2.4寸ips液晶显示屏.240x320 ST7789屏
使用自制的32g开发板顺利点亮.楼主的这款驱动功能挺全的慢慢学习使用. 本人尝试将显示幅面240x240改为
240x320成功.完美竖屏显示.如果要横屏显示就不知道怎么搞了.

上豆包,AI给解决了.下面语句按注释说明改一下就行了.
  LCD_CMD(0x36); LCD_DAT(0x60); //LCD_DAT(0xC0);竖屏翻转 // LCD_DAT(0x60); 横屏  //LCD_DAT(0x00); 竖屏//LCD_DAT(0xA0); 横屏翻转
谢谢楼主提供的这款7789驱动.功能齐全一般应用都能适用.

版主你好，我使用你的程序成功驱动tft屏，有一个问题搞不明白，主函数里去掉

          LCD_A12(120,30,"A12_012345",15,1,10);  //显示8*12字符串
          LCD_A16(120,45,"A16_012345",15,1,10);  //显示8*16字符串
          LCD_A24(120,64,"A24_0123",15,1,8);     //显示12*24字符串
          LCD_H16(65,102,"单片机STC32G",14,4);   //16点阵中西文混合显示字符串
          LCD_H24(44,135,"单片机STC32G",11,0);   //24点阵中西文混合显示字符串
，编译就出现下列错误：

去掉不用函数最多是警告，怎么出现上面的情况呢，请问什么原因，

编译系统环境尚未和谐. 所以代码编译有局限.
