Here’s a little “muxview” front-end for the MuxShield:

(it’s not very exciting since all slaves are returning the same text)

This little application recovers the individual streams from the multiplexed data coming in over USB. Screens 1..5 show what is coming from each slave channel. Screen 6 displays what came in before the multiplexer was started.

Here’s a more interesting example with 5 RFM12B receivers (you won’t be able to read the text because I had to reduce the screenshot to fit this blog). The antennas are way too short, to force weak transmissions and bad reception. As you can probably glimpse, each of the slaves has trouble with the data, but in very different ways:

This application is written in Tcl/Tk, the script is available here. I’ll tweak it further over time to fit my needs.
