简单粗暴的说: unit8_t,就是unsigned char, 数值范围是0-255, 占1个字节 unit16_t,就是unsigned int, 数值范围是0-65535, 占2个字节 unit32_t,就是unsigned long, 数值范围是0-4 294 967 295, 占4个字节编辑于 2022-05-09 20:48 Arduino ...

tft.width(); //int16_t width(void);tft.height(); //int16_t height(void); 通过这两个函数,可以了解显示器的分辨率。只需将它们添加到代码中并将输出放入 uint16_t变量中。然后从串口读取它Serial.println();。先加Serial.begin(9600);在setup()。 4、屏幕颜色 tft.fillScreen(t); //fillScreen(...
tft.fillRect(x,y,w,h,t); //fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t t)tft.drawRect(x,y,w,h,t); //drawRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t t)tft.fillRoundRect(x,y,w,h,r,t); //fillRoundRect (int16_t ...
