好的,以下是控制TMP102温度传感器的Mbed代码:
```c++
#include "mbed.h"
#define TMP102_I2C_ADDRESS (0x90) // TMP102 I2C address (8-bit)
I2C i2c(PB_9, PB_8); // I2C object, SDA=PB_9, SCL=PB_8
int main() {
char cmd[1];
char data[2];
cmd[0] = 0x01; // Pointer register to set temperature register (0x00) for reading
i2c.write(TMP102_I2C_ADDRESS, cmd, 1);
while (1) {
cmd[0] = 0x00; // Pointer register to set temperature register (0x00) for reading
i2c.write(TMP102_I2C_ADDRESS, cmd, 1);
i2c.read(TMP102_I2C_ADDRESS, data, 2);
int temp = ((data[0] << 8) | data[1]) >> 4; // Convert data to temperature
temp *= 0.0625;
printf("Temperature: %d degrees Celsius\r\n", temp);
wait(1.0);
}
}
```
请注意,此代码使用了Mbed中的I2C库来进行TMP102温度传感器的读取。在此之前,需要将L432KC开发板与TMP102传感器进行正确的接线,如下所示:
| L432KC引脚 | TMP102引脚 |
|:---------:|:---------:|
| PB_9 (SDA) | SDA |
| PB_8 (SCL) | SCL |
| GND | GND |
| 3.3V | VCC |
希望这可以帮助到你!
