|
* Driver for LIS3DH 3-axes digital accelerometer connected to I2C or SPI.
|
||
|
|
*
|
||
|
|
* This driver is for the usage with the ESP8266 and FreeRTOS (esp-open-rtos)
|
||
|
|
* [https://github.com/SuperHouse/esp-open-rtos]. It is also working with ESP32
|
||
|
|
* and ESP-IDF [https://github.com/espressif/esp-idf.git] as well as Linux
|
||
|
|
* based systems using a wrapper library for ESP8266 functions.
