LIS35DE Motion Sensor Driver Example

Communicate by ESP32 with LIS35DE 3-axis motion sensor using SPI interface.

Build Status

Build Status

Wiring of sensor used in example code

Signal Name Sensor ESP32
Slave Select SS GPIO22
Serial Clock SCK GPIO18
Master Out Slave In MOSI GPIO23
Master In Slave Out MISO GPIO19

How to run this example

Please follow ESP32 Get Started.

Example output

  1. I (257) LIS35DE Example: Starting example
  2. I (257) LIS35DE Driver: Initialize SPI
  3. I (257) LIS35DE Driver: Initialize the LIS35DE sensor
  4. I (267) LIS35DE Driver: Power up and enable all three axis
  5. I (277) LIS35DE Driver: Check if sensor responds...
  6. I (277) LIS35DE Driver: Sensor responded correctly
  7. I (287) LIS35DE Example: x:  -1, y:   3, z:  53
  8. I (487) LIS35DE Example: x:   1, y:   3, z:  53
  9. I (687) LIS35DE Example: x:   0, y:   4, z:  52

Example SPI transaction

alt textZ axis position">

Picture above shows an example SPI transaction reading sensors X:Y:Z axis position. To do so, we are using an option LIS35_ADDR_INC to automatically increment register address and retrieving axis position in a single SPI transaction.
