PIC 12F675 TO PIC 16F676 CODE CONVERSION

No,

You have used a pull down resistor. Use a pull-up resistor, or no resistor.

IR receiver output goes to PICkit2 pin 6, not pin 4

u tell as ?

 

[hexreader]

Perfect.... Exactly right..


You can use pin 2 Vdd to supply the +5V if you prefer. Remember to turn on 5V supply in PICkit2 software first

OK thank s

pl can explain its command value ?

That looks like NEC protocol to me.

As explained here:

https://www.sbprojects.com/knowledge/ir/nec.php

First picture looks to be:

0000 0001 address hex 0x80 (LSB first)
1111 1110 inverse address
0101 0000 command 0x0A
1010 1111 inverse command

Second picture looks like address 0x80 and command 0x1B

any body can help for conversion above code in CCS C ?
bcoz my hi-tech compiler has been expired .

Use the lite version!!! or download the newer XC8 from microchip... Its free to use..

Use the lite version!!! or download the newer XC8 from microchip... Its free to use..

now finally i got sesecs . those code are as , but led on continually .

my sch diagram are as

i do it with XC8. i got sesecs . but led on continually .

pl guide me where i was wrong ?

Yon cannot clear the interrupt on change flag... You need to read the port to clear it.. Create a line that reads the port..

something like this...
if(GPIO);

And the IOC should be clear.... Whats happening here is the IOC is firing and the LED is flashing very fast and appears on...

that is here all ready have here

void interrupt t0intr(void)
{
    if(INTCONbits.T0IF)  // check the timer0 over flow interrupt flag
    {
    timerInterruptIsr();// timer0 overflow interrupt has been occur call the isr
    INTCONbits.T0IF =0; // clear the timer0 interrupt flag
    }
    else if (INTCONbits.GPIF)  // check the interrupt on change flag
    {   
        LED=1;    // to blink the LED when IR signal is received
        interruptOnChangeIsr();                    // interrupt on change has been detected call the isr   
        INTCONbits.GPIF =0;                        // clear the interrupt on chage flag
        LED=0;                                    // to blink the LED when IR signal is received
    }

}

And the IOC should be clear.... Whats happening here is the IOC is firing and the LED is flashing very fast and appears on...

no no its continuous on

 

[Ian Rogers]

INTCONbits.GPIF =0; // clear the interrupt on chage flag

This will not work..... You need to read the port ie a = GPIO; or something like this....

meany meany
thank u sir . i got my problem. its solve now
