RT-Thread STM32F407 五步完成OLED移植

这里使用RT-Thread Studio提供的IIC API驱动函数进行移植

第一步，进入RT-Thread Settings配置IIC驱动
第二步，进入board.h，定义IIC宏
第三步，进入STM32CubeMX，配置时钟及IIC
第四步，添加oled.c及oled.h文件，放置appliciation文件夹下
第五步，软件配置

main.c

#include <rtthread.h>
#include <rtdbg.h>
#include <board.h>
#include <rtdevice.h>

#define DBG_TAG "main"
#define DBG_LVL DBG_LOG
#include"oled.h"

#define OLED_I2C_BUS_NAME          "i2c2"  /* 传感器连接的I2C总线设备名称 */

int main(void)
{
    struct rt_i2c_bus_device *i2c_bus;      /* I2C总线设备句柄 */
    i2c_bus = (struct rt_i2c_bus_device *)rt_device_find(OLED_I2C_BUS_NAME);  /* 查找I2C总线设备，获取I2C总线设备句柄 */
    if (i2c_bus == RT_NULL)
    {
        rt_kprintf("iic sample run failed! can't find %s device!\n", OLED_I2C_BUS_NAME);
        return RT_ERROR;
    }
    OLED_Init(i2c_bus);
    OLED_Clear(i2c_bus);

    while(1)
    {
        OLED_ShowCHinese(i2c_bus,0,0,0);
        OLED_ShowCHinese(i2c_bus,18,0,1);
        OLED_ShowCHinese(i2c_bus,36,0,2);
        OLED_ShowCHinese(i2c_bus,54,0,3);
        OLED_ShowCHinese(i2c_bus,72,0,4);
        OLED_ShowCHinese(i2c_bus,90,0,5);
        OLED_ShowCHinese(i2c_bus,108,0,6);
    }
    return RT_EOK;
}
