Hi,
Its simple..i have selected 89s52 for the same code and compiled it and debugging was also working fine. In hardware also it works perfect. But when i select 89c2051 compiling was not an issue but when i debug it reacts differently. U can see my very first posts attachment where debuging...
Hi,
Thanks. but the problem is with the software itself and not with the hardware. when im debugging with 89s52 controller the (P1 & Pins) both are toggling. but in 89c2051 only (P1) is toggling. i couldnt understand where exactly it went wrong.
Re: AT89C2051 code problem
I HAVE ATTACHED THE CODE HERE
#include<reg51.h>
//#include<reg2051.h>
sbit LED = P1^0;
void delay(ms);
void main(void)
{
P1 = 0x00;
while(1)
{
LED = 1;
delay(20);
LED = 0;
delay(20);
}
}
void delay(time)
{
int a,b;
for(a=0;a<time;a++)
for(b=0;b<200;b++);
}
Hi all,
im facing the same problem... When i change the controller to 89s52 and load the hex in controller it works fine.. But when i select 89c2051 and burn the hex into the controller its not working. In debugging also only port bits are enabling. Somewhere problem with header or selection...
Thank You. you are right when im placing a SMD component in the same X,Y co ordinates respectively one at bottom and the other at the top im not getting any error.
But im just wondering how to change the clearance parameter. at any point i cant able to change the pad width & height and the...
Hi,
Thanks for your support.
The attached image is showing a overlapping of component. but this im placing one component in top layer and the other in bottom layer. practically speaking error should not come. so im eager to know the reason for error. it says "unable to clear DRC" and its not...
It depends on the antenna what you are using(Example: 3db, 5db). in case if you are not going to use both the wireless devices at a time then u can use a same antenna for both.
but its always best practice to use a separate antenna.
Hi Frnds,
Im designing a PCB with Orcad Capture for Circuit and Orcad Layout Plus for PCB Designing. i have created a SMD Component using Library Manager and the photo is attached.
It was done using SSTOP, TOP, SPTOP, SMTOP.
Question No 1
Can i use the Opposite command by right clicking on...
