LabVIEW roboRIO I2C Master, RIOduino I2C Slave - Help

[prifken]

Hello CD,

Has anyone been able to send and receive data from an Arduino (RIOduino, in my case) via the roboRIO MXP port?

I've created a link which describes my setup with pictures:

How did you configure the addresses? I'm having trouble on the LabVIEW Write side (timeout error). I am simply incrementing a U8 and sending the result to the first register of the I2C read function in LabVIEW.

I don't think the roboRIO is seeing the RIOduino at address 4.

Thanks for the help, in advance.

Going to move this to the programming section.
