I need to establish communication between multiple Arduino nano board. I have used SPI bus on one of the Arduino board for wireless communication and I2C bus for another device. It appeared that both I2C bus and SPI bus support multiple device.

Mar 30, 2015 · I was wondering how I can get 4 Arduinos in total to communicate with each-other through a wired connection. The goal is to have the master Arduino send a number 0-100 to each of the other Arduinos. The master unit will be an Arduino Uno and the other 3 Arduinos will be Arduino Pro Minis.

Learn how to multitask your Arduino! True multi-threading is not possible on Arduino, but with this code example you'll see how to work around that.

How this all works is through something called "synchronous serial communication," i.e. you can pulse one pin up and down thereby communicating a data byte to the register bit by bit. It's by pulsing second pin, the clock pin, that you delineate between bits.

Parallel Communication. Parallel connection between the Arduino and peripherals via input/output ports is the ideal solution for shorter distances up to several meters. However, in other cases when it is necessary to establish communication between two devices for longer distances it is not possible to use parallel connection.

Oct 4, 2019 · Research on parallel communication (using pins D0-D7) reminds the reader that Arduinos use D0 and D1 for serial communication with the serial monitor and the computer hosting the Arduino IDE, and that co-opting D0/D1 for parallel communication (through PORTD) runs the risk of disabling serial communication.

The bits of data can be transmitted either in parallel or serial form. In parallel communication, the bits of data are sent all at the same time, each through a separate wire. The following diagram shows the parallel transmission of the letter “C” in binary (01000011):

Sep 6, 2017 · Want to avoid communication delays of either serial or i2c or SPI, How many bytes per second do you need to transfer? You could probably do 16 bit parallel data transfers with a pair of Ports (16 bits) using port manipulation and using one of the bits as a clock that triggers an interrupt on the receiving side.

May 5, 2024 · I am trying to make a parallel connection between a Mega2560 and a Nano with the former writing the 8 bits of a byte onto 8 pins which are hardwired to pins on the nano. (The sketch shows another two pins which are not relevant to my enquiry.)

ILI9341 parallel communication lib for Arduino. This code provides basic functions to control ILI9341 TFT touch screen using parallel interface (8 data lines, 5 control lines). You can add files ILI9341.h and ILI9341.cpp to project directory. .ino file contains a simple example of usage. ILI9341 parallel communication lib for Arduino.
