• 相关篇《STM32F1基于STM32CubeMX配置硬件SPI驱动1.8寸TFT LCD128X160 ST7735S屏幕》

• 相关ST7735驱动代码来源于基于STM32CubeIDE项目：https://github.com/ScarsFun/STM32F103C8T6_cubeIDE_ST7735_1.8_DMA

• demo驱动效果:
  
  

配置如下：

• SPI1配置如下：
  

• SPI其他自定义引脚配置
  

• DMA传输方式设置：
  

添加相关驱动文件到工程

• 添加驱动文件到对应的User目录下。
  

做好了相关源文件添加后，就无需再补充其他地方了。

数据传输方式和屏幕切换说明

• 在工程st7735_cfg.h文件中，修改SPI接口以及是否启用DMA传输以及屏幕型号切换

#define ST7735_SPI_PORT hspi1	//hspi1, hspi2, hspi3...
#define USE_SPI_DMA			//if used DMA for SPI bus

#define ST7735_1_8_DEFAULT_ORIENTATION	// AliExpress/eBay 1.8" display, default orientation 合宙的1.8"选择这个
//#define ST7735S_1_8_DEFAULT_ORIENTATION 	// WaveShare ST7735S-based 1.8" display, default orientation这是微雪的
//#define ST7735_1_44_DEFAULT_ORIENTATION 	// 1.44" display, default orientation
//#define ST7735_MINI_DEFAULT_ORIENTATION 	// mini 160x80 display (it's unlikely you want the default orientation)
