Getting Started with MicroMod

Dive into the world of MicroMod - a compact interface to connect a microcontroller to various peripherals via the M.2 Connector!

Hardware Overview

M.2 Connector

All of our MicroMod Processor Boards come equipped with the M.2 MicroMod Connector, which leverages the M.2 standard and specification to allow you to install your MicroMod Processor Board on your choice of carrier board. Most of the pins use a common pinout to ensure cross platform compatibility.

M.2 Edge Connector and Mounting

SAMD51 Processor

The brains of the processor board is the ATSAMD51J20 32-bit ARM Cortex M4 processor. An external 32.768kHz crystal is used as the clock for the ATSAMD51. However, the MCU itself has a maximum CPU speed of 120MHz. The SAMD51 should be powered with 3.3V from a carrier board's M.2 connector. The logic levels for the I/O pins are 3.3V.

SAMD51 Processor

Flash Memory

On the back of the board is the W25Q128JVPIM, which adds 128Mb (16MB) of flash memory externally.

Flash Memory

LED

A STAT LED is added to the top side of the board. This is useful debugging or as a status indicator. Additionally, you can use this to determine if the board is in bootloader mode. Pressing the reset button twice will put the board into bootloader mode causing the LED to fade in/out. This is connected to pin 13.

If you have not already, make sure to check out the Getting Started with MicroMod: Hardware Hookup for information on inserting your Processor Board into your Carrier Board.

Getting Started with MicroMod

October 21, 2020

Dive into the world of MicroMod - a compact interface to connect a microcontroller to various peripherals via the M.2 Connector!

For simplicity, we'll be using the MicroMod ATP Carrier Board to program the board. At a minimum, your setup should look like the image below with the MicroMod SAMD51 inserted into the MicroMod ATP Carrier Board with a USB-C cable.

Processor Board inserted into Carrier Board with USB cable

Qwiic-Enabled Device

If you decide to use a Qwiic device (because why not?!), simply insert a Qwiic cable between the two connectors.

UF2 Bootloader & Drivers

The SAMD51 Processor Board is easy to program thanks the UF2 bootloader. With the UF2 bootloader, the MicroMod SAMD51 Processor Board shows up on your computer as a USB storage device without having to install drivers for Windows 10, Mac, and Linux!

What is UF2?

UF2 stands for USB Flashing Format, which was developed by Microsoft for PXT (now known as MakeCode) for flashing microcontrollers over the Mass Storage Class (MSC), just like a removable flash drive. The file format is unique, so unfortunately, you cannot simply drag and drop a compiled binary or hex file onto the Turbo. Instead, the format of the file has extra information to tell the processor where the data goes, in addition to the data itself.

For Arduino users, the UF2 bootloader is BOSSA compatible, which the Arduino IDE expects on ATSAMD boards. For more information about UF2, you can read more from the MakeCode blog, as well as the UF2 file format specifiation.

Double-Tap to Launch the Bootloader

The bootloader is what allows us to load code over a simple USB interface. To upload code, you will need to manually enter bootloader mode by rapidly double-tapping the reset button (after hitting the reset button once, you have about half a second to hit it again). The board will remain in bootloader mode until power cycles (happens automatically after uploading code) or the reset button is hit again (once).

Hit Reset Button Twice to Enter Bootloader Mode

Double-tapping the reset button to enter bootloader mode.

On the SAMD51, the there are a clues to if it is in bootloader mode:

  • The D13 LED indicator will be slowly fading (may appear to be blinking).
  • Board will show up under a different COM port.
  • The board will appear as a USB mass storage device under the name USB Serial Device.

Driver Verification

To verify that your driver is working, you should see the difference in the following pictures after plugging in your SparkFun MicroMod SAMD51 Processor Board. Alternatively, once you have the Arduino IDE installed, you should also see a change in the number of available Serial/COM Ports (you may need to restart the Arduino IDE for the board to populate).

Windows

Check that the board shows up in your device manager. You can click the Start or (Windows) button and type "device" to quickly search for the application. (*On Windows 10, the quick search function is picky on the spelling of the application you are searching for. For example, you may get results using "devi" and none for "device".)

SAMD51 in Windows Device Manager

Mac OSX

Open the Terminal and run the following command ls /dev/cu.* in the Terminal and check for the following changes (your board may show up under a different device name). To open the Terminal, open your Applications folder, Utilities folder, then double-click on Terminal. Otherwise, press (Command) + space bar (Space Bar) to launch Spotlight and type "Terminal," then double-click the search result.

Mac OSX CLI Command Entry

ls /dev/cu.*
Note: If you are still unsure of how to access the Terminal, watch this video or read this Apple support article.

Raspbian

Run the following command ls /dev/ttyACM* in the CLI/Terminal and check for the following changes (your board may show up under a different device name).

Setting Up the Arduino IDE

Note: If this is your first time using Arduino IDE or board add-on, please review the following tutorials.

Install Arduino SAMD Board Add-Ons

First, you'll need to install a variety of tools, including low-level ARM Cortex libraries full of generic code, arm-gcc to compile your code, and bossa to upload over the bootloader. These tools come packaged along with Arduino's SAMD board definitions for the Arduino Zero.

To install the Arduino SAMD board definitions, navigate to your board manager (Tools > Board > Boards Manager...), then find an entry for Arduino SAMD Boards (32-bits ARM Cortex-M0+) by typing SAMD in the search bar. Select it, and install the latest version (at the time of writing this tutorial, the board definitions work with v1.8.9).

Installing the Arduino SAMD Core  with the Arduino IDE Board Manager

Downloading and installing the tools may take a couple minutes -- arm-gcc in particular will take the longest, it's about 250MB unpacked.

Once installed, Arduino-blue "Installed" text should appear next to the SAMD boards list entry.

Install SparkFun Board Add-On

Now that your ARM tools are installed, one last bit of setup is required to add support for the SparkFun SAMD boards. First, open your Arduino preferences (File > Preferences). Then find the Additional Board Manager URLs text box, and paste the below link in:

https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json

Arduino IDE Preferences Additional Moard Manager URLs

Then hit "OK", and travel back to the Board Manager menu. You should (but probably won't) be able to find a new entry for SparkFun SAMD Boards. If you don't see it, close the board manager and open it again. ¯\_(ツ)_/¯.

Installing the SparkFun SAMD Boards

This installation should be much faster; you've already done the heavy lifting in the previous section. When writing this tutorial, the board version used in this tutorial should be v1.7.6. You may have a higher version as the board if there are any updates.

Select the Board and Serial Port

Once the board is installed, you should see a new entry in your Tools > Board list. Select your SparkFun MicroMod SAMD51.

Board and COM Port Selection in the Arduino IDE

Finally, select the SparkFun MicroMod SAMD51's port when the board is connected to your computer. Navigate back up to the Tool > Port menu. The port menu will have the SparkFun MicroMod SAMD51's port, labeled as such here. On a Windows machine, the serial port should come in the form of "COM#". On a Mac or Linux machine, the port will look like "/dev/cu.usbmodem####".

Arduino IDE COM Port Selection

In the picture above my MicroMod SAMD51 is listed under COM25; this is because I've plugged in about as many microcontrollers into my computer, but the one in your port menu should be smaller.

Arduino Examples

The SAMD51 is a powerful microcontroller. Here are a few examples that highlight some of its functionality.

Example 1: Blink and Hello World!

Now that you have a Processor Board secure in the Carrier Board, let's upload a combined sketch to the board. We will combine the blink and Hello World! sketches into one. Copy and paste the following code in the Arduino IDE. Head to Tools > Board to select the correct board definition (in this case, SparkFun MicroMod SAMD51). Select the correct COM port that the board enumerated to. Hit upload.

  digitalWrite(LED_BUILTIN, HIGH);    // set the LED_BUILTIN OFF
  delay(1000);              // wait for a second
}

Check out the MicroMod SAMD51's built-in LED. The LED should blink every second.

MicroMod SAMD51 LED Blink

Open the Arduino IDE's serial monitor set at 9600 baud. You should see every programmer's favorite two-word phrase.

Hello World! with the MicroMod SAMD51 Native Serial

Want to go the extra mile? Grab a 3.3V USB-to-serial converter (in this case, we are using the Serial Basic Breakout CH340). Then connect GND to GND using a M/M jumper wire. Add another M/M jumper wire between TX from the MicroMod ATP Carrier board and the RXI pin of the USB-to-serial converter. Connect the appropriate USB cable to the USB-to-serial converter.

CH340 Connected to SAMD51 via the ATP Carrier Board

Open another serial terminal (in this case, we'll use Tera Term on a Windows) and connect to the USB-to-serial converter at 9600 baud. You should see a different message being sent from the hardware serial pin.

Example 2: Qwiic-Enabled Device Qwiic Distance Sensor (VL53L1X)

Note: If you have not previously installed an Arduino library, please check out our installation guide.

There's a plethora of Qwiic-enabled devices available to connect. In this example, we will be using a Qwiic distance sensor to test. If you have not already, head over to the Qwiic Distance Sensor's (VL53L1X) tutorial to install the library.

Qwiic Distance Sensor (VL53L1X) Hookup Guide

June 18, 2018

The Qwiic VL53L1X time of flight sensor is capable of several modes, as well as having a range of 4M. Let's hook it up and find out just how far away that thing over there is.

Connect the distance sensor to the Qwiic connector. Make sure to connect to the one labeled I2C. There is a second port labeled as I2C1. You would need to adjust the code in order to use the second I2C port.

For simplicity, we'll use the first example just like the tutorial. Open up the first example by heading to File > Examples > SparkFun VL53L1x 4M Laser Distance Sensor > Example1_ReadDistance. If you have not already, head to Tools > Board to select the correct board definition (in this case, SparkFun MicroMod SAMD51). Select the correct COM port that the board enumerated to. Hit upload.

Open a the Arduino Serial Monitor at 9600 baud and start moving your hand over the sensor.

You should see an output similar to the image below. The values will vary depending on the distance away from the sensor.

VL53L1X Output on the Arduino Serial Monitor

What's next? Try combining the distance sensor example with the HID keyboard/mouse library to wake up a Raspberry Pi from it's screensaver whenever an object is in front of the sensor. Better yet, try adding some buttons and writing code to make a game controller for a computer.
