LPS25HB pressure sensor
LPS25HB is a pressure sensor that can be used by i2c. This sensor is available on ST X-NUCLEO-IKS01A1 expansion board. datasheet is available on ST web site : http://www.st.com/content/ccc/resource/technical/document/datasheet/9a/4c/aa/72/1f/45/4e/24/DM00141379.pdf/files/DM00141379.pdf/jcr:content/translations/en.DM00141379.pdf
Use the LPS25HB (About Modules) module for it.
You can wire this up as follows:
| Device Pin | Espruino Pico |
|---|---|
| D15 (SCL) | B6 |
| D14 (SDA) | B7 |
| GND | GND |
| +5V | VBAT |
| +3V3 | 3.3 |
Note: To avoid links, you can use the ArduinoPico adaptor. In this case, check the pins to use for SPI1, it should be B8 and B9.
How to use module:
I2C1.setup({scl:B6,sda:B7});
var pressure = require("LPS25HB").connect(I2C1);
pressure.getPressure(print);
Besides the I2C connection, connect() takes an optional argument to provide debug information :
I2C1.setup({scl:B6,sda:B7});
var pressure = require("LPS25HB").connect(I2C1, 1);
pressure.getPressure(print);
