@tx as pc sends some character to zigbee @ rx zigbee receives and sends to controller ,already the code is written in controller so it works according to that
hai sir got output i modified the code as
void timer0()interrupt 0
{
//lcd_cmd(0x01);//
hr1=0;hr=0;
min=0;min1=0;
sec=0;sec1=0;
count=count++;
lcd_cmd(0xC0);
lcd_data_string("count=:");
value=(count/10);////////////for ascii conversion. it ll count upto 99...
sir i need the counter to count how many times i reset the time .i used lcd_cmd(0xc8)(i think that "conut=" ll take 6 or 7 positions in lcd after that my counting value ll be shown) to display counter value at that position but i don't know how to get that value to that position.......sir i am...
..... sir now implementing whenever i press switch(ground),the counter increment to 1.(sir i think external h/w interrupts are low level interrupt so its working when i connected to GND instead of switch).
for counting i changed the code like this
void timer0()interrupt 0
{
hr1=0;hr=0...
sir i tried my level...i put the code like this
void timer0() interrupt 1
{
min1=0;
hr1=0;
sec1=0;
}
and i initialized IE=0x84; for external hardware interrupt INT1 in the main program but didn't got output.
sir i got output to display time in lcd using 89s52.but i need the help whenever i press the switch in the board the time will start from beginning using external interrupt.
here is the code how to modify the code.
#include<reg51.h>
#define cont_port P3
#define port P1
#define dataport P2 //...
