# Circuitpython on EFR32 #
|
||
|
||
|
||
|
||
|
||
|
||
|
||
|
||
This port brings the Silicon Labs EFR32 series of MCUs to Circuitpython.
|
||
|
||
Refer to **mpconfigport.mk** for a full list of enabled modules sorted by family.
|
||
|
||
## How this port is organized: ##
|
||
|
||
- **boards/** contains the configuration files for each development board and breakout available on the port, as well as system files and both shared and SoC-specific linker files. Board configuration includes a pin mapping of the board, oscillator information, board-specific build flags, and setup for some other peripheral where applicable.
|
||
- **common-hal/** contains the port-specific module implementations, used by shared-module and shared-bindings.
|
||
- **peripherals/** contains peripheral setup files and peripheral mapping information, sorted by family and sub-variant. Most files in this directory can be generated with the python scripts in **tools/**.
|
||
- **supervisor/** contains port-specific implementations of internal flash and serial, as well as the **port.c** file, which initializes the port at startup.
|
||
- **tools/** contains Silicon Labs configurator (SLC) tool, python scripts for generating peripheral and pin mapping files in **peripherals/** and **board/**.
|
||
|
||
At the root level, refer to **mpconfigboard.h** and **mpconfigport.mk** for port specific settings and a list of enabled modules.
|
||
|
||

|
||
- MacOS: Not supported yet
|
||
|
||
Install necessary packages
|
||
|
||
$ sudo apt install default-jre gcc-arm-none-eabi wget python3 python3-pip git git-lfs gettext uncrustify
|
||
$ sudo python -m pip install --upgrade pip
|
||
|

## Build instructions ##
|
||
|
||
Ensure your clone of Circuitpython is ready to build by following the [guide on the Adafruit Website](https://learn.adafruit.com/building-circuitpython/build-circuitpython). This includes installing the toolchain, synchronizing submodules, and running `mpy-cross`.
|
||
|
||
Clone the source code of CircuitPython from Github:
|
||
|
||
$ git clone https://github.com/SiliconLabs/circuitpython.git
|
||
$ cd circuitpython
|
||
$ make fetch-submodules
|
||
|
||
Checkout the branch or tag you want to build. For example:
|
||
|
||
$ git checkout main
|
||
|
||
Following the guideline below to install required packages for SLC tool:
|
||
https://www.silabs.com/documents/public/user-guides/ug520-software-project-generation-configuration-with-slc-cli.pdf
|
||
|
||
Once the one-time build tasks are complete, you can build at any time by navigating to the port directory:
|
||
|
||
$ make BOARD=explorerkit_xg24_brd2703a
|
||
|
||
You may also build with certain flags available in the makefile, depending on your board and development goals:
|
||
|
||
$ make BOARD=explorerkit_xg24_brd2703a DEBUG=1
|
||
|
||
Clean project by using:
|
||
|
||
$ make BOARD=explorerkit_xg24_brd2703a clean
|
||
|
||
## Bring-up on the board ##
|
||
|
||
### Getting a REPL prompt ###
|
||
|
||
Connect the devkit to the PC via the USB cable. The board uses serial for REPL access and debugging because the EFR32 chips has no USB support.
|
||
|
||
#### Windows ####
|
||
|
||
On Windows, we need to install a serial console e.g., PuTTY, MobaXterm. The JLink CDC UART Port can be found in the Device Manager.
|
||
|
||
#### Linux ####
|
||
|
||
Open a terminal and issue the following command:
|
||
|
||
$ ls /dev/ttyACM*
|
||
|
||
Then note down the correct name and substitute com-port-name in the following command with it:
|
||
|
||
$ screen /dev/'com-port-name'
|
||
|
||
### Using the REPL prompt ###
|
||
|
||
After flashing the firmware to the board, at your first connecting to the board, you might see a blank screen. Press enter and you should be presented with a Circuitpython prompt, >>>. If not, try to reset the board (see instructions below).
|
||
|
||
You can now type in simple commands such as:
|
||
|
||
```sh
|
||
>>> print("Hello world!")
|
||
|
||
Hello world
|
||
```
|
||
|
||
If something goes wrong with the board, you can reset it. Pressing CTRL+D when the prompt is open performs a soft reset.
|
||
|
||
### Recommended editors ###
|
||
|
||
**Thonny** is a simple code editor that works with the Adafruit CircuitPython boards.
|
||
|
||
Config serial: Tools > Options > Interpreter > Select MicroPython > Select Port Jlink CDC UART Port
|
||
|
||
### Running CircuitPython scripts ###
|
||
|
||
At the boot stage, two scripts will be run (if not booting in safe mode). First, the file boot.py will be executed. The file **boot.py** can be used to perform the initial setup. Then, after boot.py has been completed, the file **code.py** will be executed.
|
||
|
||
After code.py has finished executing, a REPL prompt will be presented on the serial port. Other files can also be executed by using the **Thonny** editors or using **Ampy** tool.
|
||
|
||
|
||
|
||
With the boards which support USB mass storage, we can drag the files to the board file system. However, because the EFR32 boards don’t support USB mass storage, we need to use a tool like **Ampy** to copy the file to the board. You can use the latest version of **Ampy** and its command to copy the module directories to the board.
|
||
|
||
Refer to the guideline below for installing the **Ampy** tool:
|
||
|
||
