STM32F405RG HAL库 硬件I2C驱动OLED

1.创建工程.

选择外部时钟

增加PA8作为LED指示灯,增加用户标签。

选择UART1与上位机通信,选择I2C2连接OLED

生成代码后在工程属性中生成.H

2.改代码

while循环里面添加代码:

	  HAL_GPIO_WritePin(LED_Pin_GPIO_Port, LED_Pin_Pin, GPIO_PIN_RESET);
	  HAL_Delay(1000);
	  HAL_GPIO_WritePin(LED_Pin_GPIO_Port, LED_Pin_Pin, GPIO_PIN_SET);
	  HAL_Delay(1000);

创建新文件夹peripheral。

添加OLED.C OLED.H OLED_FONT.H代码参考OLED_IIC_Hrad · liuxc/STM32常见外设库 - 码云 - 开源中国 (gitee.com)

需要在OLED.H中修改I2C编号。

在main.c中添加

#include "oled.h"

OLED_Init();//此处OLED的初始化

OLED_ShowString(1, 1, "Hello World!!!");//显示字符串

点击锤子编译

在FLYMCU中通过RX TX烧录程序,将BOOT0=1。

烧录程序,BOOT0=0,RST后可查看OLED屏幕信息与LED闪烁。
