About your project
Project name: Micropython for BeagleConnect Freedom
BeagleConnect is a revolutionary technology which eliminates low-level software development for IoT and IIoT applications,such as building automation, factory automation, and home automation.What sets it apart is that it eliminates the need of relying on software libraries enabling it to be used for interfacing a greater number of sensors, actuators and indicators for communicating over various networks compared to other conventional solutions.This can be achieved since it is built with fully open source software with submissions to mainline Linux and Zephyr repositories to aide in support and porting.
The BeagleConnect Freedom is based on the TI CC1352 and is the first available BeagleConnect solution which runs the Zephyr RTOS and has mikroBUS ports along with BLE and Sub-GHz radios on it.The BeagleConnect has a few technologies at the core namely IPv6 (via 6LoWPAN),Zephyr support for IEEE 802.15.4 and Greybus from Project Ara.
The goal of this project is to port Micropython and Circuitpython support along with GPIO, I2C, SPI, PWM and ADC drivers support in Micropython for the BeagleConnect solution.After the porting is completed and the drivers have been inculcated,the practicality will be thoroughly tested with the help of MikroElektronika click boards of each respective protocol and documented on my blog.
MicroPython is a completely free and open source software that is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.A few of its salient features that will be advantageous for the BeagleConnect include:
- It provides an interactive prompt (the REPL) to execute commands immediately, along with the ability to run and import scripts from the built-in filesystem. The REPL has history, tab completion, auto-indent and paste mode for a great user experience.
- Highly configurable due to many compile-time configuration options
- Code coverage at 98.4% for the core and at 96.3% for the core plus extended modules
There is ample of documentation related to porting Micropython to the Zephyr RTOS Running on Beagleconnect. The most comprehensive guide can be found in the MicroPython port to Zephyr RTOS repository.
- I will start with installing Zephyr SDK, getting Zephyr source code, and setting up development environment followed by configuring the environment, for example by sourcing zephyrproject/zephyr/zephyr-env.sh.
- I will then clone the MicroPython repository into the home directory and build the Zephyr port for the BeagleConnect Freedom board like this:
west build -b frdm_k64f ~/micropython/ports/zephyr
- Followed by this is I will flash it to the board and start a gdb debug session using:
If I find any difficulty while navigating through I will rely on the Micropython repository and the Micropython forum page.
CircuitPython is a programming language designed to simplify experimenting and learning to program on low-cost microcontroller boards.It is majorly built for Adafruit devices and has an active community base.CircuitPython is designed with education in mind. It's easy to start learning how to program and the user gets immediate feedback from the board.This will enable even a novice user to take complete advantage of the BeagleConnect Freedom device.A few of its salient features that will be advantageous for the BeagleConnect include:
- The serial console and REPL allow for live feedback from your code and interactive programming
- The internal storage for CircuitPython makes it great for data-logging, playing audio clips, and otherwise interacting with files.
- There is no compiling, no downloading and no uploading needed due to which it runs immediately just after creating a file, editing the code and saving the file.
The core code of MicroPython is shared amongst ports including CircuitPython. There is also Documentation released by Adafruit for creating ones own port.
