atmega8 bascom i 7seg led displej (10 komada) + ADC

^{16.08.2012. u 22:10 - pre 142 meseci}

Najzad krenuo nesto sa uC i umesto da pocnem sa LED blink ja zadao sebi tezi zadatak :)

Trazio neke primere za multiplexovanje ali nesto nisam pronasao.
Smislio nesto pa mi sada treba vasa pomoc jer PROTEUS izbacuje cudne vrednosti.

Iz seme se vidi da imam 4 analogna ulaza i svaki od njih ide na 7seg LED D.
Da bi ustedeo na pinovima i pojednostavio, dodao sam 4017.
Sve OK radi bez ADC u PROTEUSU - nasumice prikazivanje brojeva,
ali ADC ne pokazuje kako ja hocu.
ADC ide od 0-1023 (ovo je vise pitanje)
Referentni napon je 2.56V (i ovo)
1023*10/40 =255 i to je najveca vrednost koju trebam da vidim na prvih 3 displeja
ali ja dobijam drugacije.
Mucim se vec neko vreme ali ne ide.
Moze pomoc?

Drugo pitanje.
Sta u programu da ubacim kako bi mogao neke vrednosti u proteusu da prikazujem - nesto kao debug prozor?

Hvala
