好的,下面是基于潘多拉开发板的rt_thread操作系统读取ap3216传感器的代码,希望能对你有帮助。
```c
#include <rtthread.h>
#include <rtdevice.h>
#include "ap3216c.h"
#define AP3216C_I2C_ADDR 0x1E /* AP3216C I2C address */
#define AP3216C_REG_ID 0x00 /* AP3216C ID register address */
#define AP3216C_REG_DATA 0x03 /* AP3216C data register address */
/* AP3216C I2C bus device */
static struct rt_i2c_bus_device *i2c_bus;
/* Initialize AP3216C */
static rt_err_t ap3216c_init(void)
{
rt_uint8_t id;
/* Check AP3216C ID */
rt_uint8_t reg = AP3216C_REG_ID;
rt_err_t ret = rt_i2c_master_send(i2c_bus, AP3216C_I2C_ADDR, ®, 1);
if (ret != RT_EOK)
{
rt_kprintf("Failed to send ID register address!\n");
return RT_ERROR;
}
ret = rt_i2c_master_recv(i2c_bus, AP3216C_I2C_ADDR, &id, 1);
if (ret != RT_EOK)
{
rt_kprintf("Failed to receive ID register value!\n");
return RT_ERROR;
}
if (id != 0x16)
{
rt_kprintf("Invalid AP3216C ID: 0x%02x!\n", id);
return RT_ERROR;
}
/* Initialize AP3216C */
ret = ap3216c_init(i2c_bus);
if (ret != RT_EOK)
{
rt_kprintf("Failed to initialize AP3216C!\n");
return RT_ERROR;
}
return RT_EOK;
}
/* AP3216C reading thread */
static void ap3216c_thread_entry(void *parameter)
{
rt_uint16_t ir, als, ps;
while (1)
{
/* Read data from AP3216C */
rt_err_t ret = ap3216c_read_data(i2c_bus, &ir, &als, &ps);
if (ret != RT_EOK)
{
rt_kprintf("Failed to read data from AP3216C!\n");
continue;
}
/* Print data */
rt_kprintf("IR: %d, ALS: %d, PS: %d\n", ir, als, ps);
/* Delay for 1 second */
rt_thread_mdelay(1000);
}
}
/* AP3216C demo entry */
int ap3216c_demo(void)
{
/* Open I2C bus device */
i2c_bus = (struct rt_i2c_bus_device *)rt_device_find("i2c1");
if (i2c_bus == RT_NULL)
{
rt_kprintf("Failed to find I2C bus device!\n");
return -RT_ERROR;
}
rt_err_t ret = rt_device_open((rt_device_t)i2c_bus, RT_DEVICE_FLAG_RDWR);
if (ret != RT_EOK)
{
rt_kprintf("Failed to open I2C bus device!\n");
return -RT_ERROR;
}
/* Initialize AP3216C */
ret = ap3216c_init();
if (ret != RT_EOK)
{
rt_kprintf("Failed to initialize AP3216C!\n");
return -RT_ERROR;
}
/* Create AP3216C reading thread */
rt_thread_t thread = rt_thread_create("ap3216c", ap3216c_thread_entry, RT_NULL, 1024, 25, 10);
if (thread == RT_NULL)
{
rt_kprintf("Failed to create AP3216C reading thread!\n");
return -RT_ERROR;
}
rt_thread_startup(thread);
return RT_EOK;
}
```
该代码首先定义了AP3216C的I2C地址和寄存器地址,然后通过ap3216c_init函数初始化AP3216C。接着,创建一个线程来读取AP3216C的数据,将读取到的数据打印出来,并延时1秒钟。
在ap3216c_demo函数中,首先找到I2C总线设备,然后打开该设备。接着,调用ap3216c_init函数初始化AP3216C,并创建一个线程来读取AP3216C的数据。
请注意,该代码仅供参考,实际使用时需要根据具体情况进行修改和适配。
