That depends on what you want to do.· For the most reliable connection I recommend using a "full" connection with flow control, that way your VB program won't attemp to send something when the BASIC Stamp isn't ready for it.· This article will show you how:

Note: Remember to add a subject line to your posts -- you'll get more responses and get them quicker (I fixed this one).

A simple example, based on the BS2 and VB, is attached
(You'll have to change the 'baudmode' parameter for the
·faster BS2sx).

Hello again

What i am trying to do is to use two (or more) ir-detectors sending their signals to Visual basic separatly(did i spell that right[noparse]:)[/noparse]

For example: when the·first ir-detector generate a·signal it will·appear a red box in VB, when the second·ir-detector generate a signal it will appear a·green box.

What you'll need to do is write a VB program, which will recieve data from the BS2 over a serial port (or a USB to Serial adapter -- they look the same to VB).

Then write a BS2 program which will 'sample' two (or more) ir-detectors, translate what it sees into some message, and send that message to the VB program using SEROUT over the serial port.

You'll need to define some kind of protocol so the VB program knows which IR detector is being communicated. Something like:

"! IR1 ON "
"! IR2 OFF "

Meaning IR1 got an ON reading (whatever that means), and IR2 got an 'OFF' reading.

Then in the VB program you can easily update the background color property of a text-box, for instance, to make it red or green.
