Rotation Counter using 8051

Rotation Counter using 8051

 I need to make a counter for a transformer winding machine .In that the winding is made by hand . so the roation  need to be keep in mind ,that is too much difficult .So the winding shaft rotaion counting by an infrared sensor module which is connected with 89S52 microcontroler and a LCD .

Infrared based Rotation Counter by 805 or  (contact less Rotation Counter  or Rotation counter without using Interrupt.

16 Bit Event Counter & Displaying on LCD1

An External Pulse Counter Using 8051 and Dispalying on 16x2 LCD 

  A circuits which is used to count the external pulses And which is displaying on an 16x2 LCD display . You can simply use this project for various purpose .It is a default  project for counting Purpose.

Tutorials : - 

To use 16 Bit counter we need to configure some register in 8051 as follows 

TMOD Register is need to configure as follows

16 bit counter Setting with timer 0

TMOD=0x05; //  Giving 0x05 it configured so .

8051 has Two Timer (each has 16 bit ) i am taking here Timer 0 It has to part First 8 bit (TL)) and the second part is (TH0) .

This timer is using to store the Pulses from the external (ie it will increment up to 65535 or FFFF)

TL0 = 0; // that timer clearing 

TH0 = 0;  // that timer clearing 

 TR0 = 1 // TR0 setting to start the counting .


Done .................................


    After setting the above register as said  the resulted value (counting value ) will save periodically in TL0 and TH0 . That value displaying after converting it to decimal . for LCD Tutorials Go Here
