Ten signed integers over I2C transmission and reciving. How?

Projects General Guidance
1

Hello
In my project i have 10 arduino board connected by I2C

Each board must send up to ten signed integers to master.
As example range can be from -100 to 100

How i can transmit this data and how i can receive it?

Please give me sample of code or link to sample.

I read build in samples but this task looks more complexity.

Thanks.
Sorry my bad english.

10 signed integers is 20 bytes - well within the 32 byte packet size.

Not to me. What have YOU tried?

One great solution/method is to utilize Bill Porter's EasyTransfer library code. There are versions to use either serial comm or I2C comm. You basically setup identical data structure in both or all connected arduino boards and just let the library code handle the actual transfer. I've only used it in serial com mode but I2C should work just as well.

I install EasyTransfer Library, restart Arduino software.
open EasyTransfer_RX_Example

trying to run it and - got a EasyTransferI2C does not name a type error
in strings

//create object
EasyTransferI2C ET;

What i do wrong?

LATER: I a complete fool. Wrong library installation :slight_smile:
