下面是MS5540C传感器的初始化代码,基于C语言编写:
```
#include <stdio.h>
#include <stdlib.h>
#include <wiringPi.h>
#define MS5540C_ADDR 0x76
void delay_ms(unsigned int ms)
{
delay(ms);
}
void ms5540c_reset()
{
pinMode(0, OUTPUT);
digitalWrite(0, LOW);
delay_ms(5);
digitalWrite(0, HIGH);
}
void ms5540c_start()
{
wiringPiI2CWrite(MS5540C_ADDR, 0x1E);
delay_ms(5);
}
void ms5540c_read_pressure()
{
wiringPiI2CWrite(MS5540C_ADDR, 0x40);
delay_ms(10);
}
void ms5540c_read_temperature()
{
wiringPiI2CWrite(MS5540C_ADDR, 0x50);
delay_ms(10);
}
int main()
{
int fd;
unsigned char buffer[3];
if ((fd = wiringPiI2CSetup(MS5540C_ADDR)) < 0) {
printf("Failed to open I2C device\n");
return -1;
}
ms5540c_reset();
ms5540c_start();
ms5540c_read_pressure();
ms5540c_read_temperature();
buffer[0] = wiringPiI2CReadReg8(fd, 0x00);
buffer[1] = wiringPiI2CReadReg8(fd, 0x01);
buffer[2] = wiringPiI2CReadReg8(fd, 0x02);
int pressure = (buffer[0] << 16) | (buffer[1] << 8) | buffer[2];
buffer[0] = wiringPiI2CReadReg8(fd, 0x03);
buffer[1] = wiringPiI2CReadReg8(fd, 0x04);
int temperature = (buffer[0] << 8) | buffer[1];
printf("Pressure: %d, Temperature: %d\n", pressure, temperature);
return 0;
}
```
以上代码仅供参考,具体实现可能需要根据具体的硬件平台和编程环境进行修改。
