Microcontroller 8051/89S52 Embedded C Programming

Hello, this very post is related to the RPM meter project. You must first of all glance over the project here. A simpler architecture can be represented below. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch. Most of the ports of the 89S52 have 'dual function' meaning that they can be used for two different functions. Shortly, RAM is used to store variable during program execution, while the EEPROM memory is used to store the program itself, that's why it is often referred to as the 'program memory'. It is the CPU that will Read the program from the FLASH memory and Execute it by interacting with the different peripherals Diagram below shows the pin configuration of the 89S52, where the function of each pin is written next to it, and, if it exists, the dual function is written between brackets.


89S52 Micro Controller Quick Tutorial

Before going into detail, we should get some brief idea about microcontroller AT89S It is 40 pin microcontroller, and has 4 ports P0,P1,P2,P3 , each port have 8 pins. We can consider each port as 8 bit register, from the software point of view. Some pins have the Dual functionality, which has been mentioned in bracket in Pin Diagram below.
