Components and Libraries

This section is for information about different reusable building blocks; primarily components and the libraries, code and information to make use of them. For more about Libraries, see Working with Libraries.

See also the main components database.

Internet of Things and Websockets

Networking examples using the officially supported library


Official USB Libraries can be found in the handbook

Here some other examples:

Custom Peripheral Drivers

The mbed libraries allow for standardized, simplified usage of more peripherals. However there are also user libraries which allow for faster, more efficient and/or more flexible use of these peripherals. With the exception of the software emulators of peripherals, these libraries are generally limitted to a subset of the mbed supported boards, so you need to make sure yours is supported!



  • FastIO - Faster versions of DigitalIn/Out/InOut


  • SoftPWM - Software PWM emulation
  • FastPWM - Allows PWM at full clock speed, or reduced speeds compared to regular mbed lib



  • SWSPI - Software SPI emulation
  • BurstSPI - High speed SPI writes when they are in large blocks (mainly intended for SPI TFTs)


  • I2C busreset - Recover from an I2C bus lockup (FRDM-KL25Z).


In-Application Programming

  • IAP - IAP for the NXP LPC1768 and LPC11u24
  • FreescaleIAP - IAP for Freescale boards

Power Management

  • Power Control - Power management functions for the original LPC1768 mbed
  • WakeUp - Wake up from deep sleep / power-down modes (various targets supported)
  • WakeInterruptIn - Allows LPC1114 to wake from deepsleep mode (other targets can use just regular InterruptIn)


  • F401RE-USBHost - USBHost library for various targets (not just F401).


  • MODDMA - DMA library for the LPC1768
  • SimpleDMA - Simplified DMA library for multiple targets

LCDs and Displays



Motors and Actuators





  • SCA61T - Single axis digital SPI inclinometer





Clocks and Oscillators

  • Si570 - Silicon Laboratories Si570 frequency synthesizer, with I2C interface.
  • Seeed Grove RTC - DS1307 based RTC module I2C
  • Adafruit_RTCLib - DS1307 RTC driver and time manipulation library
  • Maxim DS1077 - Maxim DS1077 EconOscillator/Divider Library

External ADC/DAC

  • Analog Devices AD7190 - Ultra-low noise 24-bit Sigma-Delta ADC
  • Analog Devices AD7490 - 16 channels, 1MSPS, 12 bit ADC with SPI interface
  • MCP3221 - I2C 12 Bit, Single Channel ADC
  • MCP4822 - SPI dual channel 12-bit DAC
  • MCP320x - Simplified access to the Microchip 1/4/8-Channels 12-Bit A/D Converters with SPI Serial Interface
  • PCF8591 - I2C 4 Chan, 8bit ADC and 1 Chan, 8bit DAC
  • TI ADS1X15 - I2C 12/16bit ADC, 4 ch/2 differential, programmable gain(up to 16x), comparator, 2-5.5V supply voltage
