针对您遇到的编译错误“未定义mx_i2c2_init”,我们可以按照以下步骤逐一排查和解决问题: 1. 检查mx_i2c2_init函数的声明 首先,确认您的项目中是否有mx_i2c2_init函数的声明。这通常在头文件中进行。您应该检查项目的所有相关头文件,特别是与I2C通信或硬件初始化相关的文件,看是否有类似下面的声明: c // 假设...

I2C(1) behaves similarly: I have to specify scl=Pin(25), sda=Pin(26) even though they are the defaults. Either it is necessary explicitly to specify pins for the hardware I2C or the dedicated pins are wrong. I guess this an issue withthis doc. If it really is necessary to specify ...

Solved: Hi, Occasionally my I2C bus (running as the master) locks up. And so I try and re-initialized it. I can see the slave let go and SDA and SCL
首先需要包含必要的头文件,以便在代码中使用v4l2_i2c_subdev_init函数。在C语言中,头文件是通过#include指令包含的。 ```c #include #include ``` ### 步骤2:初始化v4l2_subdev对象 接下来,需要初始化一个v4l2_subdev对象,这个对象是用来表示I2C子设备的。
