TFT_eSPI 介绍

API 大全

//以下大多 API 对 Sprite 类也通用

//初始化
tft.init(); 
//填充全屏幕
tft.fillScreen(uint32_t color); 
//屏幕旋转,参数为：0, 1, 2, 3,分别代表 0°、90°、180°、270°
tft.setRotation(uint8_t r);     
//设置光标位置，font是可选参数
tft.setCursor(int16_t x, int16_t y, uint8_t font);   
//设置字体颜色
tft.setTextColor(uint16_t color); 
//设置文本颜色和背景色
tft.setTextColor(uint16_t fgcolor, uint16_t bgcolor);
//设置字体大小,文本大小范围为 1~7 的整数,特别注意: 字库7是仿7段数码屏的样式
tft.setTextSize(uint8_t size);
//加载字体
display.loadFont(Final_Frontier_28);    
     //括号中为示例，大小为28像素的平滑字体。
     //使用平滑字体时最好用setTextColor同时设置好字体和背景颜色，否则可能会不平滑。
//卸载当前字体
display.unloadFont();
//打印
tft.print("Hello World!");
tft.println("Hello World!");

//绘制字符串
 //居左
 tft.drawString(String, int32_t x, int32_t y, uint8_t font);//font是可选参数
 //居中
 tft.drawCentreString(String, int32_t x, int32_t y, uint8_t font);//font是可选参数

代码示例

mai.cpp

#include <Arduino.h>
// New background colour
#define TFT_BROWN 0x38E0

// Pause in milliseconds between screens, change to 0 to time font rendering
#define WAIT 1000

#include <TFT_eSPI.h> // Graphics and font library for ILI9341 driver chip
#include <SPI.h>
#include <Wire.h>
#include <User_Setup.h>

TFT_eSPI tft = TFT_eSPI();  // Invoke library, pins defined in User_Setup.h

unsigned long targetTime = 0; // Used for testing draw times

void setup(void) {
  tft.init();
  tft.setRotation(3);
}

void loop() {
  targetTime = millis();

  // First we test them with a background colour set
  tft.setTextSize(1);
  tft.fillScreen(TFT_BLACK);
  tft.setTextColor(TFT_GREEN, TFT_BLACK);

  tft.drawString(" !\"#$%&'()*+,-./0123456", 0, 0, 2);
  tft.drawString("789:;<=>?@ABCDEFGHIJKL", 0, 16, 2);

  tft.drawChar(127, xpos, 64, 2);
  delay(WAIT);
}
