Mbed provides developers with a free, easy-to-use development environment. The online compiler provided by Arm can be used with evaluation boards supporting Mbed OS, and device programming can be performed with drag-and-drop simplicity on a host PC connected to the boards via USB. Developers can also access the rich component libraries verified by the Mbed community, allowing fast and efficient development of applications for embedded devices.

The Arm Mbed Device Connector service provides connectivity with the Mbed Cloud, facilitating easy configuration of web services.

Among the Toshiba group companies, Toshiba Digital Solutions Corporation is working on strengthening device security of IoT equipment as an Mbed Cloud lead partner. As Toshiba microcontrollers now support Mbed OS, the Toshiba group can propose and deliver total solutions for secure IoT systems covering clouds to devices.

Toshiba will be expanding products supporting Mbed OS with Mbed ecosystem partners.

Main features of microcontrollers supporting Mbed OS

  • Support for numerous applications with Cortex-M0 and Cortex-M4 based microcontrollers
    TX00 general-purpose microcontrollers with USB support function and TX04 microcontrollers with security function extend product choices.
  • Support for a wide range of applications via Arduino-compatible connector
    Applications can be developed quickly by connecting to a commercially available ArduinoShield board.
  • Support for IoT applications via Mbed
    Using Mbed Cloud allows secure connection with web services.
