myRIO I2C IP problem

[Slev1n]

Hey guys,

I am using myRIO and the following IP to be able to read from two different slaves:

NI 5644R LabVIEW FPGA Inter-Integrated Circuit Example https://decibel.ni.com/content/docs/DOC-26410

Here an example of its documentation for using the master.vi:

Now I have 2 questions:

1, As the myrio doesn't have the DIO-Config: "output enable done" can I use "set output enable" and set it to false?

2, I dont understand, how to use this VI and communicate with multiple slaves. The documentation says it is possible but not how to do it.

"The 10-bit addressing I2C standard adds an additional byte to the I2C transaction allowing a wider array of slave devices to be accessed." I am not sure what this means, maybe someone can help me.

Kind regards

Hey,

I found some driver from plf consulting (ni.decibel). After some minor changes it works for me 🙂
