LSM6DSOX + Raspberry Pi Pico 2 + SPI: Motion Sensor Tutorial (SPI Setup + Code Walkthrough)

🌀 LSM6DSOX (IMU) + Raspberry Pi Pico 2 | SPI Walkthrough, C/C++ Code & Datasheet Deep Dive In this video, I walk you through how to interface the LSM6DSOX 6-axis IMU with the Raspberry Pi Pico 2 using SPI communication. We go step-by-step through my C/C++ code, referencing the LSM6DSOX datasheet along the way so you understand exactly what each register and setting does. To make things even clearer, I use my Digilent Logic Analyzer to capture and visualize the SPI transactions in real time—so you can see what’s really happening on the wires. Whether you're just getting started with embedded systems or diving deeper into SPI protocol and sensor integration, this is a practical walkthrough to help you understand both the code and the hardware-level details. 📌 What You’ll Learn: Setting up SPI on the Raspberry Pi Pico Initializing and configuring the LSM6DSOX Reading accelerometer and gyroscope data How to interpret register settings from the datasheet Analyzing SPI data using a logic analyzer 🔧 Tools Used: Raspberry Pi Pico 2: https://www.adafruit.com/product/6328 ST LSM6DSOX IMU: https://www.adafruit.com/product/4438...
