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?
