Which is the more suitable way to send data between two launchpads?

HI,

I wanna share float data between two launchpads for I/O capability expansion purposes to complete robust control. As shown in the figure below, you can note that a data flow of 3 float data (vr,vt,vs) from the first control to DSP 2; while this latter transfer 9 float data. you have another way to fulfil that objective (CAN, SPI)? or which way is suitable for you?

I did a test of CAN communiction yesterday, however from the external mode I still cannot clearly observe the exact numbers of float data from the receiver, maybe it’s a matter of 20HZ sample rate from the computer and launchpad…

I reckon that changing baud rate can help???

Since can communication is widely used in industrial application,maybe it’s better？

did you try with 4 - 8 float data by CAN BUS?

I just tried the example from another forum demo…I just tried the demo by the specialist
