Arduino Due + UNO

Using Arduino Programming Questions
1

Hello,

I am using Arduino Due for my task and succeeded in getting the output value. I have one more kit Arduino UNO+Digit Shield(Digit Shield)(it's just a seven segment display with inbuilt libraries for Atmega328 ) to display the output value.

Can I send the output value from DUE to UNO to display it ? is there some communication for that ?

Thanks...

You have our permission to do that.

is there some communication for that ?

Serial, SPI, and I2C methods could all be made to work. Serial is probably the simplest.

Hello PaulS,

I read about the communications you mentioned and it is said that the devices should share common 5V and GND. But DUE has 3.3V and UNO has 5V....

Should I connect 5V on DUE to 5V on UNO ?

Also, please provide me some sample code for transferring data, if u have one.

Thanks,

Why would you?

Also, please provide me some sample code for transferring data, if u have one.

Serial.print("Which process for communicating do you plan to use?");

Please provide me any web link to study and understand about it. I couldn't understand from the available examples.
