Program to make a bidirectional visitor counter using IR sensor

[pankaj]

// the program for bidirectional counter is showing warning that delay function is not called
//and also display function is also not used

// can u please suggest me from where to call display & delay

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
SEGMENT: ?PR?DELAY?TEST4
Program Size: data=42.0 xdata=0 code=661

Hi Pankaj,

Please post your code and the error dialogue in detail.

i suggest

dont just copy n pest the code compile it and run it on hardware

pls try to understand it correctly first. try to solve any error or warning yourself first.

I too come up with same prb that display function and delay is not used in program
… But I tried through switch it works but with sensor it is not given proper output , only infinite counter is running… Plzz any one post right program for sensor ..

pls post the code

Plz any one if having program for bidirectional visitor counter using it sensor plzz post

plz post a code for bidrectional visitor counter i need it  anyone plz

Kindly provide complete detail about what type of controller you are using.

[Ashutosh Bhatt]

have you chosen the project form engineersgarage?

if yes then along with circuit there should be program also…..
