Hi Melanie,

yes the hardware name is correct .. I get this error see attached picture please .. i tried to re-assign all FPGA I/O methods and nodes .. but the error still the same ! any idea on how to solve it ?

thanks

Hi Mustafa,

since i am not sure what is the cause of the problem now, could you please try to migrate the sample I2C Communication for sbRIO project to your hardware? The only thing I could imagine at the moment is that the migration was not correct because I do not have your hardware here. I found a link, that describes how to migrate a RIO project to other hardware. It is a step by step go through. Please try this. You can find the link here:

Hi Mustafa,

have you checked the properties of the queues in the project? Refer to the original example project for information and sample properties.

If this does not fix the proble please add screenshots from the properties dialog of both queues.

Hi Melanie 

they are the same for both read and write and both projects coz i just copied it from the original target

Hi Mustafa,

since you needed to transfer the project to another hardware, you have to modify the ports that are defined in the project.

In the project file is the folder IO under the FPGA target. Please assign the data and clock ports to your hardwares clock and data ports. Connector 0 DIO 0 should be the clock, Connector 0 DIO 1 the data and so on for the second port.

Hi Melanie,

 i did and there still one problem after i re-assigned the Read/Write FIFOs

Hi Mustafa,

I think this is a code optimization related issue of the compiler. The loop that contains the Read node has to be executed for min. one time to be not deleted from the compiler. So make sure, the parameter that defines the loop iteration amount is not 0.
