ESP-IDF-ADXL345

This is an example of adxl345 accelerometer controlled by ESP32 under ESP-IDF

How to start

Set up the environment variables.(if you followed the official doc)

. $HOME/esp/esp-idf/export.sh

Go to the /example directory (/esp-idf-adxl345/example) and configure the project. My target is esp32

idf.py set-target esp32
idf.py menuconfig

Build

idf.py build

flash and monitor

idf.py -p PORT flash monitor

PORT is something like /dev/ttyUSB0, you can check it out by

ls /dev/tty*
