AT89C52 Microcontroller

Those ports can be used to output DATA mcrocontroller orders do other devices, or to read the state of a sensor, or a switch. There are two different memory types: We are using pin one of port 1 to connect the LED. Please tell Me if any one know Now I want to programm the microcontroller, what things do I need?

The above video shows lcd interface on bread board Can this project be shown on general purpose board??? Posted by Muhammad Ahmed on This should be connected to Vcc when we are not using the any external memory.

All the pins are clearly understandable by their name and functions, except the control pins, so they are explained below:. Convert to Blogger by SimplexDesign. midrocontroller

Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. We can consider each port as 8 bit register, from the software point of view.

It can be erased and program to a maximum of times. Get Our Weekly Newsletter! Quote and Order boards in minutes on https: Each consists of a latch Special Function Registers P0 through P3an output driver, and an input buffer. Code Explanation I have tried to explain the code through comments in code itself. Port P 0 and P 2 are also used to provide low byte and high byte addresses, respectively, when connected to an external memory.

Getting Started with Microcontroller. We are not using any external memory so we connected Pin31 to Vcc.

Microcontroller AT89S52 Description – Telecommunication and Electronics Projects

In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read. So we can understand by simply interfacing LED with microcontrollerthat with a simple coding that, we can interact and control the hardware through software programming using microcontroller.

Diagram below shows the pin configuration of the 89S52, where the function of each micrrocontroller is written next to it, and, if it exists, the dual function is written between brackets.
