Your title says this:
| Quote: | pic16f877a CFGWORD2 not implemented
|
But your code says this:
| Quote: | | #include <16F887.h> |
So which is it ? Those are two different PICs. |

get rid of Proteus !!!
please read PIC101
this...
PIC16 model release 8.03.00 (Build 19892) simulating PIC1684 device. [U1]
PIC16 model release 8.03.00 (Build 19892) simulating PIC1684 device. [U2]
PIC16 model release 8.03.00 (Build 19892) simulating PIC168771 device. [U3]
Loaded 64 bytes of persistent EEPROM data. [U1]
[COFF] Loading PIC COFF file 'D:\pic\rf remote pic16f84a\rf_remote_pic16f84a.COF'. [U1]
appears to ONLY simulate 2 devices, neither is your device...
so I'll assume your version of Proteus is NOT capable of simulating the PIC you're trying to use, well test. |

I changed #include <16F887.h> to #include <16F877a.h>
The problem now is I can't get 1us delay in Timer1.
Using this prescaler config
| Code: | | setup_timer_1( T1_INTERNAL | T1_DIV_BY_2 ); |
What is wrong please ? |

well I counted 5 or 6 lines where you disabled timer1( including inside the ISR) and nowhere you enable it after the first 'initialization' code..
the code seems correct
8MHz Fosc/4= 2 MHz then /2 give 1MHz which is 1us... |

Yes now it work properly. The problem with Timer1 delay come from i miss to set pic frequency in proteus to 8 MHz, by default it is 1 MHz.
Thanks for your support. |
