carrier board or the serial cable to temporarily disconnect pin 3 of the

BS2-IC (pin 4 of the DB-9 connector). The reason is that the STAMP2

host software uses this line to reset the BS2 for programming, while

terminal software uses the same line to signal “ready” for serial commu-

nication.

If you make this modification, be sure to provide a way to reconnect pin

3 of the BS2-IC to pin 4 of the DB-9 connector for reprogramming. With

these pins disconnected, the STAMP2 host software will not be able to

download new programs.

Demo Program

This demo shows the letters of the alphabet and their corresponding

ASCII codes. A brief pause slows the process down a little so that it

doesn’t go by in a blur. You can freeze the display while the program is

running by pressing the space bar.
