so how can i set the configuration word from HEX file.....and i didnt put 12mhz osc in the circuit....do i need to put it and why?
You can't set the configuration word from the HEX file it is a problem with the programmer, you have to enter the configuration word yourself via the Encrypt button. If the configuration word is not set then the watchdog timer will be active and will reset the processor before it has a chance of putting anything on to the display.
In Proteus the default frequency of a PIC processor is 1Mhz, you can change this in the properties of the device.
OK ..now i have solded the 12mhz ocs to the original circuit...and changed the frequency of pic processor to 12mhz ...also i tried to disable the WDT but still the same error......what should i do now....should i buy another programmer which doesnt have this problem..which is the best programmer that i can use which doesnt have these problems...
yah..so what should i do after loading the hex file program ....should i change it to BIN or HEX(INTEL) ...if i change it to hex(intel) it gives me a formation error then the same error non config worde error...if i chose BIN it only gives non config worde error....and after it the program windows is opened in the middle...now what should i do..can you please guide me from the beginning to end..plz......what i do is program the same thing to the ic ..till encription check it ok...after i place the ic in the base...the lcd glowing turns off....
and i dont know which config setting to put with this 16f877a..i m new at this,.,this is my first interfacing project...
- - - Updated - - -
i have tried config settings ...but still same error...plz guide me
- - - Updated - - -
also the cof file is of 21.0 kb and hex file is of 1.51kb...i m choosing hex file and loading the program...then i dont know whether to chose hex intel or bin....both of them give me the same error no matter i disable the wdt...please guide through
still the same configuration error....first i set the config settings as done by you then in load the program in hex intel ..its shows configuration worde error...and displays the data window containing data in hex......
huree! i sort it out thankx to you...the mistake i was doing was that after config setting told by you i didnt used to read config after the program loads...so once i did that also there was some wiring error..i did it...but i could not have done it without your help...*** bless you sir...here is my another video hope you like it...and thankx alot again sir..
