SHT20是一款数字温湿度传感器,它可以通过I2C总线与Linux系统连接。下面是一个可能的SHT20 Linux驱动程序的示例代码:
```
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/i2c.h>
#include <linux/hwmon.h>
#define SHT20_I2C_ADDR 0x40
static const struct i2c_device_id sht20_id[] = {
{ "sht20", 0 },
{ }
};
MODULE_DEVICE_TABLE(i2c, sht20_id);
static int sht20_probe(struct i2c_client *client,
const struct i2c_device_id *id)
{
/* TODO: Implement SHT20 driver probe function */
return 0;
}
static int sht20_remove(struct i2c_client *client)
{
/* TODO: Implement SHT20 driver remove function */
return 0;
}
static const struct hwmon_chip_info sht20_chip_info = {
.ops = NULL, /* TODO: Implement SHT20 hwmon operations */
};
static struct i2c_driver sht20_driver = {
.driver = {
.name = "sht20",
},
.id_table = sht20_id,
.probe = sht20_probe,
.remove = sht20_remove,
.detect = NULL,
.address_list = normal_i2c,
.chip_init = NULL,
.chip_exit = NULL,
};
module_i2c_driver(sht20_driver);
MODULE_AUTHOR("Your Name Here");
MODULE_DESCRIPTION("SHT20 driver");
MODULE_LICENSE("GPL");
```
需要注意的是,以上示例代码只是一个框架,实际的驱动程序需要根据硬件的具体特性进行实现。另外,该驱动程序还可以注册为hwmon设备,以便在Linux系统中通过/sys/class/hwmon/目录下的文件进行温湿度监控。
