Last week I have received the three kits. Each kit features a pre-programmed 2553 Micro. Basically the unit receives C++ commands and switches 16 output pins on and off accordingly. Furthermore the 16 pins are I/O, so the system has bi-directional capabilities. With the adhoc software this unit will look as another RS232 Port to the PC and data flow back and forth would be possible.
A control console can be downloaded and by writing in C++ you can in theory upload any script that will effect any code conversion according to any convenient standard. Surely C++ boffins at Pico could easily write the needed conversion software, myself surely being out of my depth here, at least for the time being.
In any case I shall keep you posted on what I shall eventually do with these kits.
