Hai everybody,
I want to ask about the use of Const CmdTxN, CmdRxN, CmdTxS, CmdRxS in PC2Stamp.vpp file. Why the values of each const using &HC0, &HC1, &HC2, &HC3 not the others value?
like the case in the above, Why the Con of RxNum, TxNum, RxStr, TxStr in the StampToPC.BS2 file using $C0, $C1, $C2, $C3 values?
For the answer, thank you very much.
Sincerely yours

command, the number that followed indicated function.
In VB, hex values look like this: &HC0, while the same number in PBASIC
looks like this: $C0. That said, they both represent the same value.
Note that CmdTxN (pc side) corresponds with RxNum on the BASIC Stamp
side. The reason is that $C0 indicates that the PC is transmitting a
number and the BASIC Stamp is going to receive it.
