Software Setup and Programming

Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE.

Arduino Board Definition

Installation for the STM32 MicroMod Processor is relatively straight-forward. You will want to install the board definitions via the Arduino Boards manager. Search for SparkFun STM32 and you should see the option for the STM32 MicroMod Processor show up.

A step-by-step guide to installing and testing the Arduino software on Windows, Mac, and Linux.

Install STM32Cube Programmer Software

In order to work with the STM32 MicroMod Processor, you'll need to install the STM32Cube Programmer. This is an all-in-one multi-OS software tool for programming STM32 products. It primarily provides the driver we need, but you can also program your board using this GUI.

DFU Bootloader

As of this writing, SparkFun is using the DFU bootloader to upload code to the STM32 MicroMod Processor. In order to do so, you need to do the following:

  • Press and hold down the Boot button
  • Press and release the Reset button while continuing to press the Boot button
  • Keep pressing the Boot button until the code is uploaded
