Interface LSM9DS1 9DOF IMU With TTGO T-Display ESP32

Introduction

TTGO T-Display ESP32 is a tiny microcontroller board. It comes with 1.14″ LCD, 2 programmable push button, battery connector with a charging circuit. Since it uses ESP32 module, so it has WiFi and Bluetooth capability. Plus, the price is affordable. Yes, I love it. In this tutorial, I will share how to get started with this board and interface LSM9DS1 9DOF IMU sensor module.

Sample Program

This is Arduino sample program to read LSM9DS1 data and display to LCD. It requires 2 additional library from Arduino Library Manager:

1. TFT_eSPI by Bodmer Version 1.4.16.
2. Adafruit LSM9DS1 Library by Adafruit Version 1.0.1
