M ICROCONTROLLER Occupancy Sensor 1. Send command to wake up the motherboard when a 1 is detected. 2. Sample every 5 seconds to check the pin output, if multiple zeroes are detected, set the system to idle. Keypad 1. Initialize timer interrupt service routine to 8.16ms 2. If key press is detected, send respective byte command to motherboard RFID Operation Manchester Coding – Rising edge sampling approach for reading For writing, initialize the write mode by implementing a start gap, long 1 followed by a short 0.
