Week 5 : MICROCONTROLLER

There are many types of micro controllers in the market. The one that we will be using in for our projectt is PIC 16F877a. Microcontrollers contain all the the components required for a processor system in one chip : a CPU, memory and I/O. A complete system can therefore be built using one MCU chip and a few I/O devices such as a keypad, display and other interfacing circuits. We will now see how this is done in practice in our typical microcontroller.
