You will have to tell us more about your "bs2pe board". If you can post a link to a complete description including schematics (and even artwork), that would be good.

In the meantime you can have a look at these sample programs to get a feel for the programming interface.

I can't put my hands on the board right now. I also have a daughter board which also MIA.

annamirul93,

The TC3200 Color Sensor Product Document on page 3 shows that it uses P7 of socket B for Serial I/O communication, which the BASIC Stamp 2pe Motherboard Documentation on page 4 shows is not pulled up.

P11 and P12 of Socket A are also not pulled up, but the schematic on page 5 shows the GND, P11, and +5V pins are all on the same side of the connector; The same 3 pins that the Parallax Serial LCD Product Guide shows are needed by the LCD.

Looking at the photo of the BS2pe Motherboard I see that GND is top pin next to the Jumper, P11 is the 3rd pin up from the bottom, and +5V is the bottom pin.

If you happen to have a https://parallax.com/downloads/power-input-3-pin-header-io-daughterboard-documentation, it looks easy-peasy. Just plug it in using a standard black-red-white cable.
