I have two Arduinos , side by side running the same sketch for led panels which are also side by side.
They need to work in sync to keep the pattern changes correct. Over time they get progressively out of sync.
Is syncing them through a pin connection possible?
Thank you
John

Running 4 panels : 2 16X16 on each Ardunio . The sketch goes through a color change routine.
I attached a photo of three pieces: the piece in the middle needs to go through the color change in sync.

This is the problem I am trying to solve:

AWOL ,
I was following your cue in your first post .
Sounds good. I will look it up. Is that what it is called? A sync pulse?
Pulse should come from the late one as it finishes each loup?
Thanks

To be useful, the sync pulse should be sent by the master at the beginning of it's loop logic. And it needs to be very short. The slave needs to see the pulse with an interrupt and set a boolean to indicate "go" and it needs to save the current millis or microsecond time so the main code can determine a time-out has occurred where the master is dead.
The slave logic should make one cycle if the sync boolean is set and then reset it and wait for the next pulse.

I2C communication is very popular and broadly used, because of its easy implementation in electronic devices. Reason for I2C easy implementation comes from the fact that only 2 wires are needed for communication, we do need to connect the devices to the common ground as well but the ground is not directly used in the communication.

I2C uses only 2 wires because each device has a unique address assigned to it. Therefore the master can easily know with which slave it communicates. Simply said the signal from the master goes to all of the slaves but only the slave with the correct address is going to react on the signal.

The two wires are: Serial Clock (SLC) and Serial Data (SDA). The SLC is the clock signal which synchronizes the data transfer between devices and it is generated by the master device. The SDA is the data carrier signal, basically the transmission wire.

After we have connected the hardware properly now it is time to start the programing. For enabling the I2C communication we will need WIRE LIBRARAY, which should come with Arduino programing tool by default. In case that is not there you can download it form HERE.

With this "mode" you can only send instructions form the master device to slave, but there is no feedback form the slave device. Because of that you master device has no idea what the slave device is doing. To remedy that there is the second "mode". Below you can see the MasterWriter and the SlaveReceiver.

2. Now we have to register an event that will activate every time that new data is received via I2C. This event we input as a function later in the code. Basically with this line we simply say: call this function (receiveEvent) each time you receive some information from I2C.

6. Now we create a while loop which will go through all of the bytes received but the last one. We will store these bytes inside a character variable, and show them individually on the screen. This will if you remember from the Master code display on the screen (letter by letter) text "x is ".

You can test this code by uploading the Master on one board and the slave on the second one. Connect the boards according to the wiring shown in the next step. To see the code in action you have to select the port of the slave and turn on the serial monitor, and both Arduinos need to be connected to the same ground and both need to be powered up.

Here we are going to control an LED attached to the D13 on the Slave Arduino with the Master Arduino. Master Arduino will have a Serial Monitor opened and we will write a command saying ON or OFF to toggle the LED on the Slave.

Here you can copy the master code or simply download it from the attachment down below. The attached code has an explanation for each line of the code, but in the next step of the tutorial we will explain the code in detail.

2. We define a byte variable called I2C_OnOFF with which we will send information to the slave via I2C. We start the I2C communication and Serial communication, and write on the monitor for note for a user.

3. Now we have to check if the user has inserted anything in the serial monitor and read it. We store this information through char c variable letter by letter and move these characters inside a readString string.

4. Now we create an if statement which will determine the value of a I2C_OnOff variable depending on the users input. If the user inserts "On", "ON" or "on" the I2C_OnOff variable will store number 1. If the user inserts "Off", "OFF" or "off" the I2C_OnOff variable will store 0.

1. We load the library as with the master, assign a variable to the digital pin 13 where our LED is connected (or built in). We define the same byte variable I2C_OnOff as in the master. This variable will be used with an if statement to toggle the LED.

Now we have to simply connect the two Arduinos as before. After we have uploaded the code to both boards and made sure that both have grounds connected and that both are powered up, we will choose the port of the master and turn on the serial monitor. Here we input on or off statements to toggle the LED.

This "mode" complements the first one because it enables the feedback loop between the master and the slave. Which in turn allows master to react on slaves feedback. This is very useful when master has code that uses slaves feedback for calculations, or as conditions for further code execution or as an input on the second slave that is hooked up on the master.

3. Now we read these bytes inside a while loop like before, but now we will read everything and each individual byte will be stored as a character only until it's displayed on the Serial Monitor. What we display here will be seen in the SlaveSender code.

1. We include the wire library as usually, begin the I2C communication and define the address of the slave device with the number 8, than we register an event (we call a function to be run each time the master requests information from the slave). As before we also make a small delay inside a void loop.

2. Now we will define the event (or a function) which is run each time the master requests information from the slave. Here we will simply send 6 bytes of information which form a word "hello ", if you remember from the masters code, we had to specify exactly the number of bytes that master requests.

You can test this code by uploading the Master on one board and the slave on the second one. Connect the boards according to the wiring shown at the beginning of the tutorial step. To see the code in action you have to select the port of the master and turn on the serial monitor, and both Arduinos need to be connected to the same ground and both need to be powered up.

In the next tutorial about I2C we will show you a more interesting example which will stop the motor if an object is detected by the slave. The master requests from the slave the information about the distance from the object, and if the object is too close the master stops the motor. Here we will also make a simple object avoidance algorithm.

I'm using I2C and the Arduino Library (Wire) to communicate between two Arduinos, and my code isn't working. It's supposed to read in an int from the slave, write a value to the slave, then read back that value. I'm expecting "0 4", but i keep getting "0 0". Does this mean that the slave isn't registering the write?

Stop condition: Once all the data frames have been sent, the master will generate a stop condition. Stop conditions are defined by low to high transition on SDA after a LOW to high transition on SCL, with SCL remaining high.

I connected the SDA, SCL, ground and power pins between the two boards, and ran the master code on the Atmega board (using an FTDI cable), and the slave code on the Arduino UNO (using the Arduino USB cable).

Here I establishing a master writer / slave reciever connection, and I am powering and reading the values through the USB cable connected to the slave Arduino. This code turns an LED ON on the Arduino when the button in the Atmega board is pressed.

Next was testing I2C connection on the Attiny.44 board. Since wire.h library cannot be used with attiny, I aquired a modified library TinyWire.h from here as a zip folder and added it to the libraries in Arduino.

This code is also testing the connection by pressing a button on the master and turning ON an LED on the Slave. Here, I am powering the Attiny board using Arduino by connecting ground and VCC wires along the signal wires.
