7_Inkplate_easyC example for e-radionica.com Inkplate 6
|
|
For this example you will need a micro USB cable, Inkplate 6,
|
|
BME680 sensor with easyC connector on it: https://e-radionica.com/en/bme680-breakout-made-by-e-radionica.html
|
|
and a easyC cable: https://e-radionica.com/en/easyc-cable-20cm.html
|
|
Select "Inkplate 6(ESP32)" from Tools -> Board menu.
|
|
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it:
|
|
https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/
|
|
|
|
This example will show you how you can read temperature, humidity, air pressure and gas data from BME680.
|
|
In order to compile this example successfuly, you will also need to download and install
|
|
Adafruit BME680 library: https://github.com/adafruit/Adafruit_BME680
|
|
and Adafruit Sensor library ( https://github.com/adafruit/Adafruit_Sensor ).
|
|
If you don't know how to install library you can read our tutorial https://e-radionica.com/en/blog/arduino-library/
