Hi,
I need to know the LCD commands for 8051 microcontroller,especiallyl if i press one switch corresponding number should show on lcd display,i mean 1 to 60 numbers.First one wil display ater dat 2 only it should have to show ,after completing the counting of 60, right it should show...
In my program one pushbutton for counting(0-9) ,another for stop,and another for where we stopped from there to it has to count,but in my program thrid b uuton is not working,where is the mistake plz tel me sir.
#include<reg51.h>
#define p0 P0
#define p3 P3
sbit p1=P3^2;
sbit p2=P3^3;
sbit...
Gud evening sir, i have written program for stopwatch,for dis i used four seven segments and 3 pushbuttons.My program is working except one pushbuuton,PB1 for counting and PB2 for reset and PB3 for stopping,but in my program PB3 is not working ,where is prob,plz tel me sir.
Thanks in Advance...
As you told "You have to transfer lower 4 bits one by one to each of the 4 pins(connected to 7447) of P0".u mean no need to mention control pins in coding part? please give me coding part.
Thanks u sir,now problelm with coding part,control pins of 7 segment are P0.7 to P0.4,and decoder inputs are P0.0 to P0.3,im posting coding part below plz check once that one,i have to pass value to dat perticular four pins? i got the wrong output, how to display 0 to 9999.
// Program to...
Hi,
Thanks, for ur reply,but my board having four seven segment digits,these four are connected through decoder ic (74ls47) to 89v51rd2.but i got circuit diagram for seven segment directly connected to the 89c51.How can i display 0 to 999 on seven segments.please tel me the step by step...
Hi,
I wants to get the output of seven segment(0 to 999) multiplexing,thats why i searched in google i got the program for seven segment multiplexing,but in that coding four seven segments are connected to microcontroller directly,but in my board, thery connected seven segment through buffer to...
