Concerns/Issues
• Inexperience with CPLD’s, 555 timers, 7-segment displays and decoders could lead to delays
• Concerned about how much time LabVIEW will take to set up
• Various interfacing issues

Conclusions• CPLD has been created and is ready for
testing before implementation into analog circuitry.
• We are now focused on the analog portion and having it interface with the Geiger tube.
