0.1.3 合宙CORE-ESP32-C3开发板用arduino点亮ST7735 1.8寸TFT屏【已更新失效链接2022.07.10】
9.9的ESP32开发板想用arduino开发，无奈都是用luatos玩，于是折腾了下
目的
用arduino驱动合宙ESP32-C3开发板点亮S7735TFT屏
材料
CORE-ESP32-C3开发板*1
ST77351.8寸TFT屏128*160分辨率*1
连接
实施
1、配置ESP32环境
在不丢失ESP8266的情况下，打开arduino-文件-首选项，附加开发板管理器网址
在原ESP8266的网址后面加逗号“,”
https://arduino.esp8266.com/stable/package_esp8266com_index.json,https://www.arduino.cn/package_esp32_index.json
保存，然后发现下载不了环境，直接下载离线包

在此我要特别感谢 arduino中文社区提供的小白资源，我这个萌新差点就卡死在该死的GITHUB了，附上源链接，CSDN要是封了我就直接注销这平台了Arduino IDE安装esp32 SDK（Windows）2022.7.6更新-Arduino中文社区 - Powered by Discuz!
下载完不用打开arduino，直接安装，安装完成后打开就看到开发板列表了，安装自动匹配路径
波特率921600，flashmode选 DIO
2接下来下载tft_espi，在库路径编辑......\Arduino\libraries\TFT_eSPI-2.4.61的user_setup.h文件
注意IO口是按开发板丝印的GPIO口来的并不是按ESP32pin脚来的

// Some displays support SPI reads via the MISO pin, other displays have a single

// To use the SDA line for reading data from the TFT uncomment the following line:
// #define TFT_SDA_READ // This option is for ESP32 ONLY, tested with ST7789 and GC9A01 display only
// For ST7735, ST7789 and ILI9341 ONLY, define the colour order IF the blue and red are swapped on your display

// #define TFT_HEIGHT 240 // GC9A01 240 x 240
// For ST7735 ONLY, define the type of display, originally this was based on the
// colour of the tab on the screen protector film but this is not always true, so try
// out the different options below if the screen does not display graphics correctly,
// e.g. colours wrong, mirror images, or stray pixels at the edges.
// Comment out ALL BUT ONE of these options for a ST7735 display driver, save this
// this User_Setup file, then rebuild and upload the sketch to the board again:
// #define ST7735_INITB
// #define ST7735_GREENTAB
// #define ST7735_GREENTAB2
// #define ST7735_GREENTAB3
// #define ST7735_GREENTAB128 // For 128 x 128 display

// #define ST7735_REDTAB
// #define ST7735_BLACKTAB
// #define ST7735_REDTAB160x80 // For 160 x 80 display with 24 pixel offset
// If colours are inverted (white shows as black) then uncomment one of the next
// 2 lines try both options, one of the options should correct the inversion.
// #define TFT_INVERSION_ON
// #define TFT_INVERSION_OFF
// ##################################################################################
//
// Section 2. Define the pins that are used to interface with the display here
//
// ##################################################################################
// If a backlight control signal is available then define the TFT_BL pin in Section 2
// below. The backlight will be turned ON when tft.begin() is called, but the library
// needs to know if the LEDs are ON with the pin HIGH or LOW. If the LEDs are to be
// driven with a PWM signal or turned OFF/ON then this must be handled by the user
// sketch. e.g. with digitalWrite(TFT_BL, LOW);
// #define TFT_BL 32 // LED back-light control pin
// #define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light (HIGH or LOW)
// We must use hardware SPI, a minimum of 3 GPIO pins is needed.
// Typical setup for ESP8266 NodeMCU ESP-12 is :
//
// Display SDO/MISO to NodeMCU pin D6 (or leave disconnected if not reading TFT)
// Display LED to NodeMCU pin VIN (or 5V, see below)
// Display SCK to NodeMCU pin D5
// Display SDI/MOSI to NodeMCU pin D7
// Display DC (RS/AO)to NodeMCU pin D3
// Display RESET to NodeMCU pin D4 (or RST, see below)
// Display CS to NodeMCU pin D8 (or GND, see below)
// Display GND to NodeMCU pin GND (0V)
// Display VCC to NodeMCU 5V or 3.3V
//
// The TFT RESET pin can be connected to the NodeMCU RST pin or 3.3V to free up a control pin
//
// The DC (Data Command) pin may be labelled AO or RS (Register Select)
//
// With some displays such as the ILI9341 the TFT CS pin can be connected to GND if no more
// SPI devices (e.g. an SD Card) are connected, in this case comment out the #define TFT_CS
// line below so it is NOT defined. Other displays such at the ST7735 require the TFT CS pin
// to be toggled during setup, so in these cases the TFT_CS line must be defined and connected.
//
// The NodeMCU D0 pin can be used for RST
//
//
// Note: only some versions of the NodeMCU provide the USB 5V on the VIN pin
// If 5V is not available at a pin you can use 3.3V but backlight brightness
// will be lower.
// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP8266 SETUP ######
// For NodeMCU - use pin numbers in the form PIN_Dx where Dx is the NodeMCU pin designation
//#define TFT_CS PIN_D8 // Chip select control pin D8
//#define TFT_DC PIN_D3 // Data Command control pin
//#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
//#define TFT_BL PIN_D1 // LED back-light (only for ST7789 with backlight control pin)
//#define TOUCH_CS PIN_D2 // Chip select pin (T_CS) of touch screen
//#define TFT_WR PIN_D2 // Write strobe for modified Raspberry Pi TFT only
// ###### FOR ESP8266 OVERLAP MODE EDIT THE PIN NUMBERS IN THE FOLLOWING LINES ######
// Overlap mode shares the ESP8266 FLASH SPI bus with the TFT so has a performance impact
// but saves pins for other functions. It is best not to connect MISO as some displays
// do not tristate that line when chip select is high!
// Note: Only one SPI device can share the FLASH SPI lines, so a SPI touch controller
// cannot be connected as well to the same SPI signals.
// On NodeMCU 1.0 SD0=MISO, SD1=MOSI, CLK=SCLK to connect to TFT in overlap mode
// On NodeMCU V3 S0 =MISO, S1 =MOSI, S2 =SCLK
// In ESP8266 overlap mode the following must be defined
//#define TFT_SPI_OVERLAP
// In ESP8266 overlap mode the TFT chip select MUST connect to pin D3
//#define TFT_CS PIN_D3
//#define TFT_DC PIN_D5 // Data Command control pin
//#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP32 SETUP ######
// For ESP32 Dev board (only tested with ILI9341 display)
// The hardware SPI can be mapped to any pins
//#define TFT_MISO 19
//#define TFT_MOSI 23
//#define TFT_SCLK 18
//#define TFT_CS 15 // Chip select control pin
//#define TFT_DC 2 // Data Command control pin
//#define TFT_RST 4 // Reset pin (could connect to RST pin)
//#define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST
// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins
#define TFT_MOSI 03 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 02
#define TFT_CS 07 // Chip select control pin
#define TFT_DC 06 // Data Command control pin
#define TFT_RST 10 // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL 11 // LED back-light
//#define TOUCH_CS 21 // Chip select pin (T_CS) of touch screen
//#define TFT_WR 22 // Write strobe for modified Raspberry Pi TFT only根据自己的TFT屏分辨率，是否带触摸进行配置，以上代码是按1.8寸128*160分辨率TFT ST7735屏更改的，对应开发板排线不用交叉调的GPIO口，
3打开示例，开发板选ESP32-C3 DEV MODULE ,编译刷入，不出意外直接点亮
