【目的】移植多级菜单以及贪吃蛇游戏
【实验硬件】
1、【灵动 Mini-F5333开发板】
2、旋转编码器
3、OLED屏
【开发环境】
1、MDK5.38
2、TobudOS
【步骤】
1、下载多级菜单的源码，这是我在B站上学习到的，具体是哪位，如果大佬看到请联系我一下下。
2、复制我的TobudOS工程源码：https://mbb.eet-china.com/forum/topic/139033_1_1.html
3、加载源码的key、encoder、oled到工程里，把头文件更换成mm32的头文件，添加进工作组：
4、按照OLED驱动的帖子，修改驱动：【灵动 Mini-F5333开发板】硬件I2C高速驱动OLED屏_嵌入式系统与MCU
具体的数据发送与命令发送代码如下：
/**
* 函 数：OLED写命令
* 参 数：Command 要写入的命令值，范围：0x00~0xFF
* 返 回 值：无
*/
void OLED_WriteCommand(uint8_t Command)
{
uint8_t dat;
dat = Command;
I2C_SendData(I2C2, 0x00);
while (RESET == I2C_GetFlagStatus(I2C2, I2C_STATUS_FLAG_TFE))
{
}
I2C_SendData(I2C2, dat);
while (RESET == I2C_GetFlagStatus(I2C2, I2C_STATUS_FLAG_TFE))
{
}
I2C_GenerateSTOP(I2C2, ENABLE);
while (RESET == I2C_GetFlagStatus(I2C2, I2C_STATUS_FLAG_TFE))
{
}
}
/**
* 函 数：OLED写数据
* 参 数：Data 要写入数据的起始地址
* 参 数：Count 要写入数据的数量
* 返 回 值：无
*/
void OLED_WriteData(uint8_t *Data, uint8_t Count)
{
uint16_t i;
I2C_SendData(I2C2, 0x40);
while (RESET == I2C_GetFlagStatus(I2C2, I2C_STATUS_FLAG_TFE))
{
}
for(int i =0; i < Count; i++)
{
I2C_SendData(I2C2, Data[i]);
while (RESET == I2C_GetFlagStatus(I2C2, I2C_STATUS_FLAG_TFE))
{
}
}
I2C_GenerateSTOP(I2C2, ENABLE);
while (RESET == I2C_GetFlagStatus(I2C2, I2C_STATUS_FLAG_TFE))
{
}
}
