Summary
This chapter examines the nature of the synchronous serial protocol used by the BASIC
Stamp to communicate with the ADC0831. The clock signal, data signal and analog input
were viewed. The activity demonstrated how to configure the OPTAscope with the Trigger
Mode switched to Normal to capture signals, and made use of the Auto Measurements feature.

1. Describe a way to estimate how long it takes for the BASIC Stamp
2. Look up the datasheet for the Analog Devices ADC0831 on the Internet, if
command to execute.
possible. Does the chip have other features with different signals that you could
verify with the OPTAscope?
This text by Tracy Allen, PhD., has additional examples of serial communication
using the DS1620 digital thermometer. It also has useful applications for signal
demonstration due to the variety of communication between the DS1620 and a
BASIC Stamp. It is available online from the Stamps in Class Curriculum menu
