Extremely simple arduino code to receive transmitted data
Extremely simple arduino to transmit
Works well between 2 arduino nano if connected as
For OBC I should also use 4.7k resistor ? ( without resistors nothing works)
I want to write a function that will send data over i2c into arduino for a test.

LPC_I2C0 LPC_I2C1 LPC_I2C2 LPC_I2C3
???
Can you please tell which side (X+, X-,Y+,Y-) correspond to which LPC_I2C* device ?
3) I also remember that LPC_I2C devices should be switched ??? depending on which side we indent to use.
Please explain it again here in issues. How to select which I2C side on OBC (X+,X-,Y+,Y-) should be used and how to switch it ?
