SPC sends packets to the UART, but not raw bytestreams. You need to encapsulate your printf() argument into a message, send the message via SP, and then decode it on the PC using the Java, C, or Python tools.

Hi Joe, Can you give us an example of using the UART interface with SPC. I had already a function that printf to the UART with HPLUART.put(), but when I integrated it with SPC, it stop working.
