Secondly connect your sensors to the SPI pins, selecting a new CS pin for each sensor. Arduino SCK (pin 13) to all the SCK pins. Arduino MISO (pin 12) to all the SO pins. Individual GPIO pins to individual CS pins (use pin 10 for one of them). Then just use a simple function to read the data using the SPI library (adapted from the library you

Using SPI in Arduino. Before start programming for SPI communication between two Arduinos. We need to learn about the SPI library used in Arduino IDE. The library is included in the program for using the following functions for SPI communication. . 1. SPI. begin() USE: To Initialize the SPI bus by setting SCK, MOSI, and SS to outputs, pulling SCK and MOSI low, and SS high.

Plug your Arduino to your desktop via the serial cable. Open the arduino Serial Monitor and set the bitrate to 115200. Now, on the Raspberry Pi, run the compiled code. sudo . /spidev_test. You should see HELLO WORLD print in the Arduino IDE Serial Monitor. Debugging. Make sure that your kernel has the required drivers (spi-bcm2708. ko and spidev. ko)

How do you use SPI on an Arduino? - Arduino Stack Exchange

Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to.

/29/2016I have an Arduino Mega (2560 r3). I have a couple of questions: 1. If I use the ICSP header, does that directly link to pins 50 - 52. On the pinout diagrams it says 50, 51, 52 are on the block of connectors and the ICSP header. 2. Pin 53 is the default pin for slave select for SPI on the mega.
