bs2 USB-datalogger

Archiver

Hi,

Working on a project to make a datalogger from a BS2 i'am reading a
lot of messages on this group. So far i spend a lot of time in
finding out how the stamp works and also the DS1302(clock) and (extra)
eeprom, ADC's, etc,etc.... also programming in VB and find out that
there are some difficulties (is this good English?) with the serial
protocol (i.e. i read data exchange with visual basic from Jon
Williams). But i do have some questions i hope somebody wil answer :-)

-Is it possible to program VB6 to communicate true USB with the BS2?
-Is there a example programm off how to program the BS2 to be a
(simple) datalogger or at least, a start how to..?

thanks in advance

I'm not sure what you mean by 'true USB'. The BS2 does
not do USB -- it does serial. The KeySpan 19W
USB to 232 adapter works really well under the VB6
'COMM' control (232 control). This would let you
connect a BS2 to the USB channel on your PC, using
232 protocols.

For your second question, I'm sure the Parallax
'Nuts and Volts' area has something on datalogging.

Scott Edwards still has the manual for the DCPB (Data Collection
Proto Board) on line for download:
http://www.seetron.com/pdf/dcpb_mnl.pdf

It is an excellent reference to get you started.

Hi There,

USB can be implemented with a stamp easily.
Also, datalogging is easy as well.

My site has some pointers that will help get you started:

http://www.lennard.net.nz/lennardelectronics/index.html

Click on circuit ideas, and then go to the USB and datalogging
sections.

Implementing "True USB" will be impossible, due to the
complexity of the protocol, etc. This is easily overcome by using
a chip from FTDI (details are on my website).

cheers,
