扩展库使用说明——ST7735S显示屏

本帖最后由 blue 于 2022-7-21 14:02 编辑

1-硬件概述
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      
1GND接地
2VCC电源（默认3.3V,可由模块背面电阻更改）
3SCLSPI的时钟信号
4SDASPI的主设备输出，从设备输入信号（即MOSI）
5RES屏幕复位信号
6DC数据（1）和命令（0）控制管脚
7CS片选/使能信号
8BL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。
