. Eigentlich super für die meisten Projekte hat diese kleine Platine alles was man so braucht. Wenn man jetzt aber ein Display anschließen will braucht man bei den einfachen Displays eine menge Pins. Allerdings braucht man auch noch Pins für vieles andere in einem Projekt. = Problem. Dafür [ Sending data from our Arduino to the I2C devices requires two things: the unique device address (we need this in hexadecimal) and at least one byte of data to send. For example, the address of the part in example 20.1 (below) is 00101111 (binary) which is 0X2F in hexadecimal

We will be using the LCD in 4-bit mode, this means you don't need to connect anything to D0-D3. The R/W pin is connected to. You can see the I2C devices available by typing ls /dev/*i2c*. You need to select an I2C address for the Arduino. You can choose any byte you want for the address, just so long as it is not being used by another device in the chain. In this example, the Arduino is the only device being used. So it does not matter It uses the pins on the Arduino which are dedicated to I2C, so for example on the Arduino Uno it uses pin A4 as SDA and A5 as SCL. For all of its great features, it has some shortcomings - Wire does not allow you to have multiple I2C buses, you can only call one instance of it and you can't redirect your I2C traffic to different pins

I'm using a PIC24FJ128GA010 (with an Explorer 16 development board) and an Arduino UNO. I want to set the PIC as I2C MASTER and the Arduino as SLAVE. According to my logical analyzer, the PIC is writting everything as it's supposed to: writes the slave address, receives an ACK and then starts writting a string. However, I'm using the Wire. The Arduino uses 7bit I2C addresses, and our own documentation uses 8bit addresses. For example our CMPS03 is at address 0xc0, but on the Arduino you will use 0x60. The Arduino address is the same as our address, but shifted right by 1 bit. The binary of 0xC0 is 11000000, the binary of 0x60 is 01100000. The Arduino will shift this left by 1bit and add the Read/Write bit automatically. You can. Hello every one ! welcome back ! It's nice to show you my new tutorial after long time .Today we will learn how to connect multiple I2C device (typically for demo temperature sensor ) to the Arduino Uno .I recommend download datasheet of that I2C device you are going to interface with Arduino before jump into coding The hardware configuration described have been tested with an Arduino UNO R3, a 16×2 LCD, and an I2C LCD backpack purchased from an eBay seller.

This tutorial of Robo India explains how to get address of i2c device connected to a NodeMCU using Arduino IDE. Detailed Tutorial 1. Introduction: 2C bus is a means of connecting several peripheral input and output devices that support I2C on two wires. One of those wires is the DATA line called the SDA, whereas the other is the CLOCK line. I want to connect it to my arduino uno using i2c. my question is: 1. 04 is the address we defined in the Arduino sketch. —> so couldn't we change the address to 01 or 02 or ? 2. I send data from arduino to raspberry. So i make counter in arduino then i send that counter to raspberry. So far is it running well, my counter is 1,2,3,50,90,110,255 is it fine and raspberry can show data. In the past there were two separate Arduino libraries for using the Adafruit NFC boards. One library supported the breakout over a SPI connection, and the other library supported the breakout or shield over an I2C connection. However both of these libraries have been merged into a single Arduino library, Adafruit-PN532 In this Tutorial we are going to Interface I2C LCD 16X2 Module with Arduino Uno and display our Name on LCD.
