Microcontroller

Our 8051 microcontroller is Externally interfaced to EPROM where our code is stored.

Microcontroller Tasks include:

	Read sensors, compress and store these readings in microcontroller internal RAM for the next transmission.
	Control servo motor where ultrasonic sensors are put.
	Transmit sensors data serially to PC in frames:
	Frame consists of 56 bits.
	Frame is updated and sent every 1/3 sec.
	Every bit is transmitted for 750 usec.

Microcontroller cycle is 1/6 second length, and has the following flowchart

Polling technique is used in our program, because it’s much simpler and we weren’t in need to interrupts.
