Programming TouchShield Slide

Hi,

is it possible to programm TSS without Arduino board? I was thinking to connect USB cable direct to pin 2 and 3 on TSS. Before I do that and try, maybe someone already did it.

What about assigning UARTs... On Arduino it is possible to assign more UARTs using NewSoftSerial and other libraries.. is there a similar library for TSS to? On TSS I would like to use pin3 as Rx and pin4 as Tx.

tnx, Luka
