Running multiple slave devices on Arduino SPI bus
Raspberry Pi to Arduino SPI Communication Overview. of Raspberry Pi Arduino communication we'll now present a simple application in which the Pi sends a command to the Arduino to add or subtract two numbers and the Arduino returns the result. Creating an application that solves a math problem avoids the need to interface any additional
Handling two SPI devices on Arduino Mega - Stack Overflow
To witness the capability of SPI for controlling more than one slave device, I have chosen two Arduino UNO boards as SPI slaves for this demo. Arduino/Genuino Uno is a microcontroller board based on the ATmega328P ( datasheet ).

Arduino I2C Tutorial: Communication between two Arduino Boards
/23/2018I have problem because I want to connect two device to my arduino. First is module mfrc522 and module SDCard. Both are with SPI interface. Please help me I am using library MFRC522. h and SD libary in arduino. Thanks
SPI Communication Between two Arduino Boards - MyCircuits9
In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has only two wires while SPI uses four and I2C can have Multiple Master and Slave, while SPI can have only one master and multiple slaves.
or 24 or 28 inch SPI TFT LCD ILI9341 to Arduino Uno
/22/20152. 2 or 2. 4 or 2. 8 inch SPI TFT LCD ILI9341 to Arduino Uno Over the weekend I figured out how to interface a 2. 8 inch SPI TFT that has a ILI9341 chip to an Arduino Uno. All it takes is eight 1K resistors. Most people use a 4050 IC. Here is the schematic.
