thanks for the links.. i'm going through the links you suggested but its making me very difficult to understand.. please can you tell me some code for counter using interrupt pin. i'm trying to solve my keyboard problem. please help me out in counter part. that i mentioned in the above post...
it will be helpful if you provide a sample code or link to work on this interrupt based keyboard because i never worked on it before.
i want to clarify one more doubt... i'm measuring the 1400rpm motor speed with IR sensor and it rotates 100 counts in 4sec. i need to read the sensor value and...
i agree with you. but i never done keyboard interface using interrupt.. can u please give a sample code for this so i can Analise and implement in my codes.
i already done it.. but its not working as i want.. i alter the code n combined with 4x4 keyboard code too.. as i told early user will enter the the 3 digit code which has to display on 3 digit display and adc will read from the input and it will count untill the user defined number and which...
its my mistake sorry for that and thank you so much for your care about my code. i solved out that issue long back now the problem is as bellow.
there are two set of display. one 4 device 7segment is using to display the current count of adc output and another 3 device 7segment display which is...
hello mgate, i tried your code o and i increased the delay time but still its having the same problem. and i didnt get know about ISR in that link.. i'm not getting its the code problem or proteus problem.. i simulate this in protues and i'm getting the following message.. check out the attachment.
ya.. i tried that too.. generate the hex code in mikro pro and dumped that hex file in my circuit that i built in proteus.. its still giving the same problem.. what would be the wrong thing in my code..
hi every one..
i'm facing some problem in my projects. i worked it on proteus and i have attached some snaps shot of my project. i'm reading analog i/p from RA2 and display it on 4 7-segments devices. i used 74ls78 bcd to 7 segment decoder and 74ls138 decoder. i've copied my source code too with...
thank you for replying.. at present i dont know power rating of motrs. is it really makes difference (power rating) to just on and off the motor. i understood your concept.. but i cant able to c the attached picture clearly.. the pic is too small.. do you wish to tell any thing else so i need to...
hello every one..
i got struck in a project where i need to turn on and off three motors depending on the operation using pic 16f877..
1. 24v dc motor
2. 230v ac motor
3. 24v ac motor
can any one please suggest me how to operate these motors with pic 16f877.. do i need any triac or mosfet or...
