No BASIC Stamps found
I just set up my BASIC Stamps Homework board and followed the directions under Activity #4 to create my first program. When I go to run the program a communications error box pops up indicating No BASIC Stamps found. However, when I go to Identify if the board is connected via the serial port the Loopback & Echo fields indicate Yes on COM1, indicating the serial communications was established.
What do I need to do to resolve this issue?
Thanks

You will find, this is the most common error when using batteries. Most Stamp users eventually switch to using a power adapter to prevent this kind of problem. It's not real fun when you go to play/work with your stamp, and find your battery dead, and have no more around the house. It's even worse if you live in a place that all the stores close at 7:00 pm on Sunday night, and you can not get a battery.
Hope you have fun with the Stamp.

i replaced the battery ,but can't solve this problem and BASIC Stamp Editor v2.3.9 Show "yes" on loopback and echo only , can't find the BS2 ......
BS2 connect to PC by USB , i changed the cable ,but.... can't solve this problem
Is BS2 damage ?
Thanks
1) The Stamp has to be running. That means that it needs power and it can't be "broken".
2) The Stamp has to be connected to a PC running the Stamp Editor. That means that it needs to be connected as shown in the Stamp documentation including the capacitors shown in the ATN line in the documentation (if you're using RS232). The Board of Education has this circuitry. If you're using a USB interface, it has to properly implement the DTR signal. Parallax's USB to serial adapters do this. Keyspan's High Speed USB to Serial Adapter does it. USB to Serial Adapters from FTDI (the manufacturer of the adapter chips that Parallax uses) do it. Some other USB to Serial Adapters do it, but there's no list. You'll just have to experiment.
3) If you're using a USB to Serial Adapter, you may have the wrong driver software installed on your PC. The default Windows driver for USB to Serial Adapters does not work for downloading programs to a Stamp. You must install the manufacturer's driver.
It's possible but unlikely that your BS2 is damaged. Almost all cases of "No BASIC Stamps found" are due to one of the above issues.
My case same as case1 , (The Stamp has to be running. That means that it needs power and it can't be "broken".)
My Stamp can connected to PC and can wrote·programs to stamp yesterday , but i have find "No BASIC Stamps found" on Editor today
so I replace the battery....·
My stamp include the USB·SYSTEM ·.
i don't know how to solve this problem...

There have been some cases where the USB cable was defective. Try changing that.
It's much more difficult than you think to damage a Stamp to the point where it won't work.
If you have a multimeter or oscilloscope available, you could check that the Vdd voltage on the Board of Education is 5V (in relationship to Vss - ground).
My battery is 9V
the stamp have Error , why it was damage -.-
thank Mike Green
the stamp Vdd-Vss voltage is 5.03V .
the board Vdd-Vss voltage is 4.93V .
On board , there have two capacters near the battery ,
C1 voltage is 5.03V (near battery" - " )
C2 votage is 4.93V (near battery " +" )
The borad is Error ?
I don't have any new suggestions. Like I said, it's harder than you think to damage a Stamp.
If you're located in the United States, call Parallax Tech Support. If you're located elsewhere and bought your Stamp from a distributor, give them a call. They may be able to help.
Both bs2's work in the original board, with both power supplys.· niether bs2 will be found in my brand new boards.· I would not have bothered, to post, except that while debugging i ran across your post and noticed the recent timeline.. Maybe a batch of bad boards?·· best of luck......··
