I have had some requests from people wanting to control their 1st Gen LivingColors via RS232. The current solution is just a shield on an Arduino and it would not make sense to build something on an other platform.
Of course, i could make it all mote complicated by combining the CC2500 shield with a serial shield but that would require some hacking.
The first versions of the Arduino used a serial port to communicate with the PC via RS232. Pieter Floris still had a couple of these boards in store. Instead of making the solution more complicated i could then make the solution quite simple.
I assembled the board myself so I cannot blame the people from Arduino for all the hacking needed, the crystal could have been a lower model. The 7805 on the BOM is in a TO220 however. Without rasing the connectors the shield is never going to fit.
It seems the whole “shields” concept did not exist when the first Arduinos were built.
With some compromises the shield fits..
I have tested it and I can now control the LivingColors via RS232. No changes in de software or the shield are needed.
