# sensor-hp203b
C library for interacting with the HP203B barometer sensor.
Features:
* works with the Raspberry Pi and probably with almost every single-board computer equipped with I2C
## Installation
Copy all the files ending with `.c` and `.h` into your project folder.
## Usage
```
#include
#include
#include
#include
#include "hp203b.h"
int main() {
int i2c_fd = open("/dev/i2c-1", O_RDWR);
if(i2c_fd < 0) {
return -1;
}
hp203bt* hp203b;
error* err = hp203b_init(&hp203b, i2c_fd, DSR_4096);
if(err != NULL) {
return -1;
}
err = hp203b_do_adc(hp203b, 1);
if(err != NULL) {
return -1;
}
double p;
err = hp203b_get_pressure(hp203b, &p);
if(err != NULL) {
return -1;
}
double a;
err = hp203b_get_altitude(hp203b, &a);
if(err != NULL) {
return -1;
}
double t;
err = hp203b_get_temperature(hp203b, &t);
if(err != NULL) {
return -1;
}
printf("%f %f %f\n", p, t, a);
return 0;
}
```
