以下是一段标准的嵌入式Linux的IIC驱动代码,供参考:
```
#include <linux/module.h>
#include <linux/i2c.h>
#include <linux/init.h>
static int i2c_driver_probe(struct i2c_client *client, const struct i2c_device_id *id)
{
printk(KERN_INFO "I2C driver probe function called\n");
// TODO: Add initialization code here
return 0;
}
static int i2c_driver_remove(struct i2c_client *client)
{
printk(KERN_INFO "I2C driver remove function called\n");
// TODO: Add cleanup code here
return 0;
}
// Define the list of I2C devices that this driver supports
static const struct i2c_device_id i2c_driver_id[] = {
{ "my_i2c_device", 0 },
{},
};
MODULE_DEVICE_TABLE(i2c, i2c_driver_id);
// Define the I2C driver structure
static struct i2c_driver i2c_driver = {
.driver = {
.name = "my_i2c_driver",
.owner = THIS_MODULE,
},
.probe = i2c_driver_probe,
.remove = i2c_driver_remove,
.id_table = i2c_driver_id,
};
// Register the I2C driver
static int __init i2c_driver_init(void)
{
int ret;
printk(KERN_INFO "I2C driver initialization function called\n");
ret = i2c_add_driver(&i2c_driver);
if (ret < 0) {
printk(KERN_ERR "Failed to register I2C driver\n");
return ret;
}
return 0;
}
// Unregister the I2C driver
static void __exit i2c_driver_exit(void)
{
printk(KERN_INFO "I2C driver exit function called\n");
i2c_del_driver(&i2c_driver);
}
module_init(i2c_driver_init);
module_exit(i2c_driver_exit);
MODULE_LICENSE("GPL");
MODULE_AUTHOR("Your Name");
MODULE_DESCRIPTION("I2C driver for my device");
```
需要注意的是,这段代码仅为示例代码,具体实现要根据具体的I2C设备和需求进行修改。
