RaspberryPi-Arduino-SPI-Comm Contains Raspberry Pi and Arduino applications. The purpose of the applications is to perform data transfers between Raspberry Pi and Arduino using SPI communication. The ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

This project allows to create a modbus communication between Arduino Uno and Raspberry Pi 2, using a switch and ethernet cables and then using a WIFI hotspot. The application is an example, the ...

Another key differentiating factor between the two platforms is connectivity. Not only does the Raspberry Pi sport more I/O pins than the Arduino, but it has a good range of communication ports, too.
