Kapag di mo na ma-iprogram.

Mahirap naman sabihin kasi na sira yung pic kasi di tumatakbo program, malay natin, program lang pala yung may diperensya or corrupted.

minsan napro-program pero hindi na nave-verify, kapag chineck, hindi na napapalitan 'yung laman ng ibang block.

pwede ring kapag sinaksakan ng voltage, iinit, madalas eto 'yung mga nababaligtad ng lagay o na-overvoltage.

ang pinakaworst dyan eh, nagcompile at napoprogram. pero mali pala yung program (ex logics)!!!

using a descent programmer (like pikit2, hehehe), di na yan madedetect!

khit simple program lng hindi p rin masasabi n sira ung PIC

na burn ung program at n verify pero ayw gumana...sira b ung PIC (simpleng program lng po)??

d b dapat ung compiler ay d mag be-build pag mali ang logic??

mabuti pa post mo yung code mo...

eto naman sakin, and usually ginagawa ko is itetest ko sa ibang pic kung gumagana. pag gumana sa extra PIC, ibig sabihin sira na yung tinetest kong pic. yun nga lang kung pareho sira yung pic sira din ulo mo. hahaha

pwedeng gawing project ng students ito. Gumawa ng hardware na mag-check thoroughly kung sira na ba talaga ang chip

Pina-iilaw lng po un pins maliban sa PORTA <7:6>

maganda yan

cnu namn kya gagawa??

eto ang absolute! pero sa simula palang, dapat siguruhing di sira ang ulo mo mismo! hehehe

sa code n yan ginawang output lahat,, tapos disabled namn ung PIN <7:6> dahil XT

d2 namn po ehh pina-iilaw lng ung pin...
hindi po b?

Dufox™ · « **Reply #15 on:** March 14, 2009, 02:45:18 PM »

wal po include dun ?

MikroC kc po yan me built-in wiz pang kinon-fig ung PIC...bali nka-link n dun pag kinompile..

toasted siopao · « **Reply #16 on:** March 14, 2009, 02:55:01 PM »

I see your MCLR is disabled, so ibig sabihin, yung MCLR mo is gagamitin mo pwede sa I/O.

Di ako marunong sa microC, you are using PIC16F628A, sure ka ba na naprogram mo sya properly? Kasi kapag nagprogram ka sa PIC16F628, dapat nakaground yung LVP pin.

Ito lang na notice ko, ano pinagkaiba ba ng ~0xFF sa 0x00?

juzkidding · « **Reply #17 on:** March 14, 2009, 04:24:31 PM »

hmm.. Check your WDT (watch dog timer).. kung naka enable nag auto reset ang PIC nyan.. hehe

Check mo sa config disable mo yung WDT tapos ok na yan.. Peks man!
