## input:
- d = "/dev/i2c-1"
- a = 0x76 (BMP280 on CJMCU8128 breakout board)
- accuracy = "ULTRA_LOW","LOW","STANDARD","HIGH","ULTRA_HIGH"
## output:
- p = uint32 ( pressure in unit Pa )
## Calibration:
Refer to https://cdn-shop.adafruit.com/datasheets/BST-BMP280-DS001-11.pdf
## Find your device address
````
i2cdetect -y 1
````
## Find BMP280 Device ID, should be 0x58 or 0x56 or 0x57
````
i2cget 1 0x76 0xD0
````
## Sample Code
````
package main
import(
"log"
"github.com/zack-wang/go-bmp280"
)
func main(){
// Atmosphere Pressure
p,err:=bmp280.ReadPressurePa("/dev/i2c-1",0x76,"LOW")
if err!=nil{
log.Fatal("Not BMP280",err)
}else{
log.Println("p=",p)
}
}
