Siguro kapag may comment na ganyan sa microC, yan na yung setup ng micro, di pa namana ako nakagamit ng microC.

Kasi kapag nagprogram ka sa PIC16F628, dapat nakaground yung LVP pin.

JDM programmer po gamit ko...
alin po ba d2 ung LVP pin???

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

wala! ganda lng tingnan parang high level ang dating

I suggest not to use ~0xFF kung 0x00 talaga ang gusto mo. nakakalito.

ang isang pwedeng purpose niyan is kung active low 'yung output mo like sa displays. kung gusto mo magpalabas ng 10101010 sa LED na naka-common anode, imbes na 0x55, ~0xAA ang gagamitin mo dahil mas kita mo na AA talaga 'yung gusto mo. pero kung hindi naman inverting 'yung logic, huwag na lang siguro.
