Learn MBED-C-CPP-PYTHON with Real Code Examples

MBed OS is a real-time operating system for embedded devices, supporting C/C++ and Python (via MicroPython).

Provides hardware abstraction for sensors, actuators, and communication interfaces (I2C, SPI, UART, GPIO).

MBed Studio and online compiler allow coding, compiling, and flashing firmware to boards.

Supports Python for scripting and quick prototyping via MicroPython on supported devices.

Widely used for IoT, robotics, wearables, and educational embedded projects.

RTOS with threading, timers, and event handling

Peripheral drivers for GPIO, PWM, ADC, I2C, SPI, UART

Networking stack: Ethernet, Wi-Fi, BLE, MQTT

Filesystem abstraction and external storage support

Secure firmware updates and cryptography APIs

Pins - digital and analog I/O

Timers - for scheduling and delays

Threads - concurrent execution using RTOS

Peripherals - sensors, actuators, communication interfaces

Scripts - MicroPython programs for embedded tasks

Application source files (.cpp/.c or .py)

MBed OS library files

Header files (.h) for drivers and APIs

Configuration files (mbed_app.json, targets.json)

Optional scripts for deployment or testing

Select target MBed board

Write application in C/C++ or Python

Compile code using MBed Studio or online compiler

Flash firmware to the device

Test, debug, and iterate on hardware
