Problem se zapojenim PIC-4026-2003-7seg

[Milan Horák]

Zdravim,

uz asi tyden marne patram, kde by mohla byt chyba.
Zapojeni je v priloze, program v textu zpravy.

1.Problem - pocita to jen kdyz je RES na 4026 odpojeny od PIC
		(obcas se to svihne a pripojeni RES funguje jako reset 				celeho 
zarizeni - to muze ale byt kontaktnim polem)
2.Problem - pocita to neuveritelne rychle, z toho co jsem 
vykoukal na 				netu (cheapic), by to melo pocitat rychlosti asi 			 
1cyklus/4sec, je to ale spis 40cyklu/sec.

Mohl by mne nekdo nakopnout ... spravnym smerem.

Diky, Milan.
