    Problem with Pic18f97j60

    Yes. I got it what you were actually explaining. Now am able to properly receive the authorised card. I have made one more change too. USART_TX_INT_OFF. Initially it was ON. This also caused a major problem in my comparison. Thanks a lot for all ur help. An other problem rooted out. As you can...

    Problem with Pic18f97j60

    I tried ur code but that too did not help to sort out my issue. What i found was actually in a single interrupt "34 32 30 30 41 34 36 41 31 39" code will be obtained in RCREG1 and it has to be stored in another variable for comparison. But according to ur code it doesnt happen. for a single...

    Problem with Pic18f97j60

    Actually each card has a code equivalent to "34 32 30 30 41 34 36 41 31 39". Whenever card is exposed this data has to copied from RCREG to another variable for comparison. So am storing each value in the form of array. And regarding ReadUSART() and WriteUSART() functions am not familiar in how...

    Problem with Pic18f97j60

    No no. Actually am working with rfid tags and reader. the code works fully whenver the tag is exposed first. But it does not respond when second card is exposed. That is problem. If the pic board is reset using reset button then it works for one time. for each time , before exposing the card if...

    Problem with Pic18f97j60

    Yes am using C18. Baud Rate is 9600. And FOSC2=ON, FOSC=HSPLL. Returning to main problem is solved now by using INTCON as a whole register instead of INTCONbits.GIE and INTCONbits.PEIE. I have used watchdog timers so that my code would work continuously without hanging. But my staff has said me...

    Problem with Pic18f97j60

    I tried it. But thats not working. And i have few more doubts too. 1. Is including number of operations to be performed within the routine a good way of writing program. 2. When i took some of the tasks that were not needed to be include within the interrupt outside and placed in main() function...

    Problem with Pic18f97j60

    My code is working properly except in the transmission of green code. I have placed the authorised ID tag code in ucCharBuff[0] to ucCharBuff[9] and green code to be transmitted to rfid for 4 cycles in ucCharBuff[10] to ucCharBuff[19]. Whenever authorised card is exposed the green code has to be...

    [SOLVED] Problem with PIC18F97J60 board

    task is whenever the rfid generates an output it is fed as input as input to D_IN1. which is port c 3rd pin. i have to check for that input periodically. whenever input is obtained a task has to be done. for simplicity now am glowing an led.

    [SOLVED] [Moved] Digital Input from PIC18f97j60

    Hi all, Am able to get a digital input at D_IN1. I am trying to check this using an LED at PORTJ. So what i do here is whenever the corresponding LED of D_IN1 goes high i should make an LED glow. My LED that corresponds to D_IN1 is glowing but the condition that is use to make PORTJ LED is not...
