STC MCU drive 1.8 'TFT SPI screen demonstration example (including data package)

STC Single chip drive 1.8‘TFT SPI Screen demonstration example （ Including data package ）

---

• Drive demo
  
• STC SCM uses ： STC12C5A60S2
• 1.8‘TFT The screen is ; Hezhou 1.8‘TFT The screen

Drive reference package

• originate ：http://www.lcdwiki.com/zh/1.8inch_Arduino_SPI_Module_ST7735S_SKU:MAR1801
  

We should be good at using materials to learn , Although here we use the universal 1.8" tft The screen , But they are the same as their driver chips . On the screen of Hezhou, the official information is only for their development board , This cannot stop our extended use of the screen , We should make good use of the resources at hand to give full play to the maximum value .

• In the package 2 Two driving modes ： simulation SPI And hardware SPI Driving mode

Wiring instructions

This example demonstrates the use of hardware SPI Interface , The model of single chip microcomputer used STC12C5A60S2, Below RS The corresponding universal is DC Pin

// The default data bus type of this module is SPI
// LCD module   Single chip microcomputer 
// SDA  Pick up  P15 //SPI Write the signal 
//======================================= LCD control line wiring ==========================================//
// LCD module   Single chip microcomputer 
// CS  Pick up  P13 // Chip selection control signal 
// RST  Pick up  P33 // Reset signal 
// RS/DC  Pick up  P12 // data / Command selection control signal 
// CLK  Pick up  P17 //SPI Clock signal
