Physical Cup Design
Physical Cup Design
Design Concerns• Small voltage provided by thermocouple• Voltage divider circuit
• Initialize D-FFs at 25⁰C• Include initialize button
• Potential for bit overflow• Finish testing for all cases
Conclusion• Project is on Schedule• Parts have been ordered and received• MOSIS design is on Schedule• Physical design has been finalized
