1-硬件概述
st7735s-1.jpg
ST7735S是可用于262k彩色的TFT-LCD型控制/驱动器,该芯片可以直接连接到外部微控制器,并可使用串行接口(SPI)/8位/9位/16位并行接口。显示数据可以存储在132x162x18 bits显存中。

在当前的ST7735库只支持SPI模式通信,最大分辨率为128*160,565格式显示。

  2-硬件连接

引脚编号
引脚名称
    引脚功能      
1
GND
接地
2
VCC
电源(默认3.3V,可由模块背面电阻更改)
3
SCL
SPI的时钟信号
4
SDA
SPI的主设备输出,从设备输入信号(即MOSI)
5
RES
屏幕复位信号
6
DC
数据(1)和命令(0)控制管脚
7
CS
片选/使能信号
8
BL
背光控制(高电平亮)
在ST7735库中可选择使用硬件SPI或者直接使用GPIO模拟SPI。
如果使用硬件SPI的话,需要确认硬件SPI是哪几个引脚,在ch32v中硬件SPI默认使用的scl时钟引脚是PA5,MOSI主机输出从机输入引脚是PA7,MISO主机输入从机输出引脚是PA6(在该库中没有使用到,但该引脚也无法作为其它引脚使用)。
如果使用模拟SPI可以任意选择引脚(没有已经用作其它用途)连接,只要保证实际和程序设置的引脚一致即可。
