  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

C3-Mini ST7789

• CS To GPIO7 (SS)
• DC To GPIO8 (SDA on board)
  • SDA引脚是OLED显示屏中的一个重要引脚，也是I2C总线通信协议中的数据线。它主要负责传输数据，包括控制命令和显示数据。
• RST To GPIO9 (SCL on board)
  • SCL引脚详解是指OLED显示屏中的时钟线引脚，它主要用来控制数据传输的速度和同步
• SCL to GPIO4 (SCK on board)
  • SCK为同步时钟
• SDA to GPIO6 (MOSI on board)
  • MOSI为主输出从输入，MISO为主输入从输出

/**************************************************************************
  This is a library for several Adafruit displays based on ST77* drivers.

  This example works with the 1.14" TFT breakout
    ----> https://www.adafruit.com/product/4383
  The 1.3" TFT breakout
    ----> https://www.adafruit.com/product/4313
  The 1.47" TFT breakout
    ----> https://www.adafruit.com/product/5393
  The 1.54" TFT breakout
    ----> https://www.adafruit.com/product/3787
  The 1.69" TFT breakout
    ----> https://www.adafruit.com/product/5206
  The 1.9" TFT breakout
    ----> https://www.adafruit.com/product/5394
  The 2.0" TFT breakout
    ----> https://www.adafruit.com/product/4311


  Check out the links above for our tutorials and wiring diagrams.
  These displays use SPI to communicate, 4 or 5 pins are required to
  interface (RST is optional).
