Thanks for the reply again. I am not really sure if Stamps have UART or not. However, what we are using is the bluetooth which can be fit into the development board directly and is able to connect to the PC via the Bluetooth transmitter and a Bluetooth dongle. Yes, even though it couldn't be used to measure voltage directly, but by implementing ADC0831 and some PBASIC codes, it should do the voltage measurement job. So basically, what we do not know is how to acquire the data using labview. Time is indeed really short and the budget is somehow limited.
