【STM32CubeIDE】STM32F103硬件SPI驱动1.8寸TFT LCD128X160 ST7735S

✨虽然STM32CubeIDE也是基于HAL库,但是还是不能直接转Keil MDK工程,本驱动案例从GitHub下载来的,原始工程使用的是较老版本的STM32CubeIDE配置的,没法在继续在新版本上程序配置,工程只是做了初始化配置。程序并不能直接被点亮,重新配置了lcd初始化函数以及复位函数后,才点被亮屏幕,同时调整好了屏幕显示像素便宜的问题。点亮屏幕是关键,后续可以很方便移植到Keil MDK环境下开发使用。

引脚定义

采用的是硬件SPI2:MOSI(SDA):PB15,SCK:PB13

//引脚定义

#define GPIO_TYPE GPIOB

#define LCD_CS 11 //片选CS引脚 PB11

#define LCD_RS 10 //寄存器/数据选择DC引脚 PB10

#define LCD_RST 12 //复位引脚RES PB12

#define LCD_BLK 8 //背光引脚 (可以不接,或接3.3V) PA8
