* Systems using the Linux I2C driver stack can declare tables of board info * while they initialize. This should be done in board-specific init code * near arch_initcall() time, or equivalent, before any I2C adapter driver is * registered. For example, mainboard init code could define sev...
52 * registered. For example, mainboard init code could defineseveral devices, 53 * as could the init code for eachdaughtercard in a board stack. 54 * 55 * The I2C devices will be created later,after the adapter for the relevant 56 * bus has been registered. After that moment, standar...

如 GPIO 初始化代码生成在 gpio.c 中。点击 GENERATE CODE 生成代码 5.3 添加全局变量 在main.c 头部添加写地址 0xA0,读地址 0xA1,写缓存区 WriteBuffer,读缓存区 ReadBuffer。/* Private variables ---*/I2C_HandleTypeDef hi2c1;UART_HandleTypeDef huart1;/* USER CODE BEGIN PV */#define ADDR_24LCxx...
__i2c_first_dynamic_bus_num定义在drivers/i2c/i2c-boardinfo.c文件中: 38int __i2c_first_dynamic_bus_num; 因为__i2c_first_dynamic_bus_num是一个全局变量,所以其值被自动初始化为0。所以73行的if判断是成立的。 76-89行,循环遍历info数组,用i2c_board_info变量初始化structi2c_devinfo指针变量devinfo...

Using Real-World Example i2c_test Just like before, thei2c_testprogram is executed from the console. It takes no parameters. root@som9x25:~#./i2c_test A menu will appear in the terminal: Select a function to test: a: Set slave address b: Write byte to register c: Write 2 bytes to...
Installing Project Code To use with CircuitPython, you need to first install a few libraries, into the lib folder on your CIRCUITPY drive. Then you need to update code.py with the example script. Thankfully, we can do this in one go. In the example below, click the Download Project ...
Board holding the I2C device, for example, EIUA or OIUA. arg3 BOM code. Impact on the System The iBMC cannot read the information about the I2C device, which may cause board exceptions and failure to monitor component status. Possible Causes The I2C link or device is faulty. Procedure ...
