AT89C52 Microprocessor programing

The four C codes for each AT89C52 microprocessor were written with µVision IDE and used in a circuit simulation with Proteus

Features

• First AT89C52:
  • identifies and understands each button press signal from a phone keypad
  • listens and speaks to other microprocessors
• Second AT89C52:
  • displays information on a two-part 7-sigment display
  • listens and speaks to other microprocessors
• Third AT89C52:
  • controls two motors speed and rotation direction
  • listens and speaks to other microprocessors
• Fourth AT89C52:
  • showing information on a JM164ASPEC display
  • uses custom characters on a JM164ASPEC display
  • listens to other microprocessors
