Mbed 2 releases¶

mbed and mbed-dev are currently released every two months.

Getting Started¶

• Prepare your Computer - Communicate between an mbed microcontroller and a PC
• Writing a library - Write or contribute to a reusable piece of code
• Add auto-generated documentation to a library
• Debugging - A guide to help find and solve errors and bugs in your programs
• Exporting to offline toolchains. Work offline and online
• Questions - Questions and answers. Ask here first.
• Help - How to ask for help

Using mbed libraries¶

The mbed library provides the C/C++ software platform and libraries to build your applications. Note: Not all platforms have the resource required to implement these APIs or have them implemented.

• mbed Memory Model - The memory model used by the mbed Library
• RTOS Memory Model - The memory model used when the mbed-rtos is included in a program

Analog I/O¶

• AnalogIn - Read the voltage applied to an analog input pin
• AnalogOut - Set the voltage of an analog output pin

Digital I/O¶

• DigitalIn - Configure and control a digital input pin.
• DigitalOut - Configure and control a digital output pin.
• DigitalInOut - Bi-directional digital pins

• BusIn - Flexible way to read multiple DigitalIn pins as one value
• BusOut - Flexible way to write multiple DigitalOut pins as one value
• BusInOut - Flexible way to read/write multiple DigitalInOut pins as one value

• PortIn - Fast way to read multiple DigitalIn pins as one value
• PortOut - Fast way to write multiple DigitalOut pins as one value
• PortInOut - Fast way to read/write multiple DigitalInOut pins as one value

• PwmOut - Pulse-width modulated output

• InterruptIn - Trigger an event when a digital input pin changes.

Timers¶

• Timer - Create, start, stop and read a timer
• Timeout - Call a function after a specified delay
• Ticker - Repeatedly call a function

• wait - Wait for a specified time
• time - Get and set the realtime clock

Digital Interfaces¶

• Serial - Serial/UART bus

• SPI - SPI bus master
• SPISlave - SPI bus slave

• I2C - I²C bus master
• I2CSlave - I²C bus slave

• CAN - Controller-area network bus

Real-time Operating System¶
