USB is a convenient way to get power, but we might not need it any longer, at least for debugging IO.
The latest Segger software J-Link V5.10q has a terminal emulator (called RTT Viewer) that will talk to the TS06.2 over the j-link. The good news is that it seems really fast – faster than the 38K4 that I’m using over USB.
The nice thing about it is that attaches to the Jlink debugger automatically. Most of the time it sits there showing an annoying little progress window.
After the program has loaded into the TS06, the JLink viewer pops open and displays IO. Here’s my dumb test program.
