Embedded Pi is a triple-play platform for Raspberry Pi, Arduino™ and 32-bit embedded ARM. Blending all three communities together, Embedded Pi helps you to get the most out of each platform. The Embedded Pi is based on the STMicroelectronics STM32F103 MCU and form factor compatible with Arduino™ shields, it can operate as a bridge between Raspberry Pi and Arduino™ shields and in standalone mode as a Cortex-M3 evaluation board.

Depending on the jumper placement on the Embedded Pi, you can select each of the three modes of operation:

STM32/Standalone Mode : The Embedded Pi works as a base platform, the STM32 controls the Arduino™ shields directly without the use of Raspberry Pi. It can interface with outside world and can control surroundings by sending & receiving input/output using wide variety of sensors; like controlling lights, motors, and other actuators.

A quick & easy embedded project can be built in C using CooCox development tools, a FREE and easy-to-use ARM development tool environment for Cortex-M MCU with flash programming & debugging capability (CoIDE, CoFlash, CoLinkEx etc), along with the integrated abundant reusable code shared by CooCox team and CoFans.

ST-Adapter Mode: The Embedded Pi STM32 controls the Arduino™ shields, and the Raspberry Pi works as the GUI or command line console to send commands/data to and receive data from Embedded Pi. This is an advanced mode which extends and strengthens the automation control capability of the Raspberry Pi, taking the advantage of STM32F103 NVIC (Nested Vectored Interrupt Controller), GPIOs, and more peripherals like ADC and PWM.

Raspberry Pi Mode: The Embedded Pi works as a hardware connection bridge between Raspberry Pi and Arduino™ shields, allowing the Raspberry Pi to interface directly with existing Arduino™ shields, having a number of sensors & control to interact with external environment. It offers all the possibilities of connecting digital and analog sensors using the Arduino™ shield but with the power and capabilities of Raspberry Pi.

The Embedded Pi, Raspberry Pi & Arduino™ shields together offers reasonably powerful embedded development platform with more processing power, greater I/O and fascinating display quality.
