AT89LP52 Microcontroller

• Input: ADC module, LM335, thermocouple, buttons
• Output: Serial to PC (via USB), PWM SSR control, speaker, LCD, LED

system

OPAMP

• Assemble OP AMP
• Attach OP AMP to thermocouple
• Attach LM335 for temperature offset
• Attach sensors to ADC, attach ADC to microcontroller

• Program reflow FSM shown in diagram on lecture slides
• Integrate FSM with interface
• Test FSM
• Add required sound and LCD outputs during each transition

important: crtTemp should be temperature input from sensors

• Wire up crtTemp to sensors

• Update LCD Screen for each state

• Make marcos for incrementing and decrementing temperature

• Program what happens when you press start while on the main screen

• Make macros for setting time

• Modify code for 3 digit temperature readings

• Unit test interface

• Unit test FSM

• Integration to main program
