Tutorial

This is a guide for incorporating MrT modules into a project. The guides walks through the full implementation of a project using MrT, a generated device driver, and a custom messaging protocol. This guide will be broken up into stages.

The project files are all in the mrt-tutorial repo and there is a ‘reference’ branch with Tags showing the end of each stage

At head of the master branch is the project start. An STM32 project has already been created to target the STM32L4 ( Their IOT node dev board)

• Uart1: 115200 baud

• I2C2

• GPIO PB14 as output, labeled as LED_GRN

Note

The setup for this project is not in the scope of this tutorial, but using STM32CUBE is pretty well documented online

Steps

• Step 1: Installing tools
• Step 2: Add MrT Modules
• Step 3: Toggle LED
• Step 4: Create a device driver
• Step 5: Create a PolyPacket Service
• Step 6: Customize the service
• Step 7: Interact with poly-packet
