How IrRemoteCodeCapture.bs2 Works

remoteCode
The BS2sx and BS2p handle remote codes a little differently. The programs usually
search for the actual start pulse with a
resting state between messages. They also use
pulses since the
before the starting edge of the next data pulse. To see a code example that does this, see

BASIC Stamp 2 Series Application Example IrRemoteButtonDisplay.bs2
You can use this application example with BASIC Stamp 2, 2e, 2sx, 2p, or 2pe modules
to test your remote and display which key you pressed.
