Demo Program (SERIN_SEROUT2.bs2)
' SERIN_SEROUT2.bs2
' Using two BS2-IC's, connect the circuit shown in the SERIN command
' description and run this program on the BASIC Stamp designated as the
' Receiver. This program demonstrates the use of Flow Control (FPin).
' Without flow control, the sender would transmit the whole word "Hello!"
' in about 1.5 ms. The receiver would catch the first byte at most; by the
' time it got back from the first 1-second PAUSE, the rest of the data
' would be long gone. With flow control, communication is flawless since
NOTE: This example program was
written for BS2’s but it can be used with
the BS2e, BS2sx, BS2p, BS2pe, and
BS2px . This program uses conditional
compilation techniques; see Chapter 3
for more information.
