stm32笔记[2]-HAL库驱动2.4寸屏幕

硬件平台

开发板:蓝桥CT117E-M4(DK117E-M4)
主控:STM32G431RBT6
内置CMSIS DAP调试器(STM32F103C8T6)
官方例程运行频率:80MHz

原理图

STM32G4主控	STM32F103的CMSIS-DAP	板载调试器与目标mcu关系

烧录(CMSIS DAP)

SWDIO : J8跳线
SWCLK : J6跳线
NRST : J7跳线

(跳线帽在中间就对了)
USB转串口（板载）烧录(KEIL通过CMSIS-DAP)(占用PA9,PA10)

开发环境

STM32CubeMX引脚配置
Keil uVision 5.35编译

屏幕

主控:ILI9328/ILI9325/UC8230
尺寸:2.4寸
分辨率:320x240

编译然后生成hex文件

KEIL设置CMSIS-DAP调试:

然后在KEIL点击调试:
