esp8266测试1.44英寸TFT屏(驱动7735)的demo

参考这教程:

使用esp8266点亮福利屏型号st7735的1.44的TFT屏
管脚连接：
我的用的TFT1.44寸ST7735，与NodeMCU针脚接线成功连接
VCC——3V
GND——G
LED——3V
CLK——D5
SDI——D7
RS——D6
RST——D4
CS——D8
这里给出常用的屏幕管脚定义

以及esp8266nodemcu的管脚定义，协助理解接线：
RS——D6
CS——D8
RST——D4
是因为在Arduino\libraries\TFT_eSPI\下的User_Setup.h中有定义：

遇到的错误：

报错找不到 <TJpg_Decoder.h> 这个库，网上找了一番没有相关的帖子，自己找到这个网站,下载了1.0.7的版本
，解压放到了对应arduino的libraries文件夹下，直接编译通过。

给出测试的demo

//屏幕驱动库
#include <TFT_eSPI.h>
//spi驱动库
#include <SPI.h>
//图片解码库
#include <TJpg_Decoder.h>// bilibili的图标
#include "img/bililogo.h"//背景颜色
uint16_t bgColor =0x0000 ;
//线框颜色
uint16_t  xkColor= 0xFFFF;
// 上一次刷新时间
int AprevTime = 0;
// 第Anim张图
int Anim = 0;TFT_eSPI tft = TFT_eSPI();  // 引脚请自行配置tft_espi库中的 User_Setup.h文件
TFT_eSprite clk = TFT_eSprite(&tft);bool tft_output(int16_t x, int16_t y, uint16_t w, uint16_t h, uint16_t* bitmap)
{if ( y >= tft.height() ) return 0;tft.pushImage(x, y, w, h, bitmap);// Return 1 to decode next blockreturn 1;}void setup() {// put your setup code here, to run once:Serial.begin(9600);tft.begin(); /* TFT init */tft.invertDisplay(0);//反转所有显示颜色：1反转，0正常tft.fillScreen(0x0000);tft.setTextColor(TFT_WHITE, 0x0000);// 设置屏幕显示的旋转角度，参数为：0, 1, 2, 3// 分别代表 0°、90°、180°、270°//根据实际需要旋转tft.setRotation(3); TJpgDec.setJpgScale(1);TJpgDec.setSwapBytes(true);TJpgDec.setCallback(tft_output);tft.fillScreen(0x0000);
//  tft.fillRoundRect(0,0,128,128,0,bgColor);//实心矩形//绘制线框tft.drawFastHLine(0,0,128,xkColor);tft.drawFastHLine(0,18,128,xkColor);tft.drawFastHLine(0,106,128,xkColor);tft.drawFastVLine(80,0,18,xkColor);tft.drawFastHLine(0,88,128,xkColor);tft.drawFastVLine(32,88,18,xkColor);tft.drawFastVLine(85,88,18,xkColor);
}void fanspush()
{TJpgDec.drawJpg(1,108,bililogo,sizeof(bililogo));
}void loop() {// put your main code here, to run repeatedly:fanspush();
//  myImage();
//  imgAnim();
}

对应的.h文件大家可以自己生成参考这个网站
我这也给出

#include <pgmspace.h>

也就是说告诉mcu（板子）存在FLASH中，而不是SRAM中，这里给出FLASH与SRAM的区别：
