mbed-js-lps22hb
LPS22HB library wrappers for Javascript on Mbed
About library
Helper class providing functions for LPS22HB sensor library (part of X_NUCLEO_IKS01A2) in JavaScript.
Requirements
This library is to be used with the following tools:
See this project for more information: mbed-js-example
Dependencies
You need to install dependencies before installing this library.
- If using SPI: mbed-js-spi
- If using DevI2C: mbed-js-devi2c
Installation
-
Before installing this library, make sure you have a working JavaScript on Mbed project and the project builds for your target device. Follow mbed-js-example to create the project and learn more about using JavaScript on Mbed.
-
Install this library using npm (Node package manager) with the following command:
cd project_path
npm install syed-zeeshan/mbed-js-lps22hb
Usage
/*****************
* Instantiation *
*****************/
// Instantiate LPS22HB library
var lps22hb = LPS22HB_JS();
/******************
* Initialization *
******************/
// Initialize using DevI2C
lps22hb.init_i2c(dev_i2c);
// Initialize using DevI2C, address and int pin
lps22hb.init_i2c(dev_i2c, address, int_pin);
// Initialize using SPI and CS pin
lps22hb.init_spi(spi, cs_pin);
// Initialize using SPI, CS pin, int pin and SPI type
lps22hb.init_spi(spi, cs_pin, int_pin, spi_type);
/***********************
* Reading sensor data *
***********************/
// To read temperature data (string output)
lps22hb.get_temperature();
// To read pressure data (string output)
lps22hb.get_pressure();
Example using DevI2C (Nucleo-F429ZI)
// Initialize DevI2C with SDA and SCL pins
var dev_i2c = DevI2C(D14, D15);
// Instantiate LPS22HB library
var lps22hb = LPS22HB_JS();
// Initialize LPS22HB library
lps22hb.init_i2c(dev_i2c);
// Print sensor data
var temp = lps22hb.get_temperature();
var press = lps22hb.get_pressure();
print("[Temperature]: [" + temp + "]");
print("[Pressure]: [" + press + "]");
Example using SPI (Nucleo-F476RG)
// Initialize SPI with MOSI, MISO, SCLK pins
var spi = SPI(PB_15, NC, PB_13);
// Instantiate LPS22HB library
var lps22hb = LPS22HB_JS();
// Initialize using SPI and CS pin
lps22hb.init_spi(spi, PA_3, NC, 3);
// Print sensor data
var temp = lps22hb.get_temperature();
var press = lps22hb.get_pressure();
print("[Temperature]: [" + temp + "]");
print("[Pressure]: [" + press + "]");
