Hi there
I am looking for some advice as to where to start to put my iPaq 2200 to work as a datalogger.
As a person with little electronics knowledge and experience (but I am willing to learn), I want to connect the following:
signal -> voltage -> multiplexer -> RS232 (or USB) interface -> iPaq ->
CF card
I am looking to log about 10 channels at 5-10Hz. I can probably deal with the signal to voltage interfaces, some being frequency to voltage,
others temperature, others pressure etc.
I have downloaded the Microsoft eMbedded tools (VB and C++) which will (hopefully) allow me to write an application for the iPaq.
My question for you guys is; can anyone point me in the right direction
for circuit diagrams/designs for multiplexers that can connect via RS232 or USB? Or even a DIY project to do the whole job.
Thanks in advance
PP
