sir bali sa left side na push button bali yan ang count up ng bawat teller at sa kabila ay ang count down ng bawat teller. tag iisa sila ng push button..

Bakit ganun? May count down. Diba ang queueing pasulong parati?

BTW, ang pin 11 (Load) ng 74192 ay dapat pull-up.

^ minsan sir rine-request ng mga bumibili para pwedeng balikan 'yung mga hindi lumalapit (baka sakaling lumabas lang daw sandali, etc.). or kapag na-misfire lang 'yung count UP nung teller.

This is meant to be an exercise sa logic design sa eskwela and not a commercial product. Baka maging too complicated at di makaya ng mga studyante. Having to deal with two tellers pressing at the same time is hard enough. But one teller pressing his/her up button and the other teller pressing the down button...

Sa ngayon they can't even produce a two digit counter circuit that works. Paano pa ang logic ng clocking and latching from two tellers with just the up buttons?

ibigay sa customer yong down count button para paglumampas sa numero niya, e down count niya

para walang suntokan

ito praktical na problema sa priority number counters, kung pwede lagyan nyo ng electronic bell yong counter!

dapat kada pendot nong teller o tindera dapat mag-bell naman para wala ng sigawan at ma alert naman kaming nagpipila na nagchange na yong number.

yong up count dapat isa lang TINNG!!

yong down count dapat marami... ting ting ting ting!!!!

okay ts? pagnagawa mo ito pasado kana..

Eto ang "sample". Pwede pa ma improve. Like, pwede ninyo lagyan ng down count. Pwede ma improve ang debounce. Pwede lagayn ng "bell". But IMHO, it's outside the scope of the exercise at ginawa nang negosyo.

Sounds like ninenegosyo nila. Kung ayaw nilang simple, they should stop reusing these exercises. Parang wala na silang alam iba. GSM, queueing system, etc. Paulit ulit lang. The students will simply build upon or reuse mga ginawa ng iba.

this is true.. paulit-ulit na lang.. hehe.. minsan kasi, wala ring initiative ung mga students to go out their comfort zones at magexplore.. maybe lack of interest or sadyang ginagawa na lang ung mga requirements for the sake na pumasa.. si prof naman, mairaos lang ung sem ok na

---------------------------------------

pero meron pa ring mga prof na ayaw ng paulit-ulit.. ayun.. daming binabagsak..

---------------------------------------

@ts, goodluck sa "pagbuo" ng circuit.. kaya nyo yan.. pagkatapos ng sem, try to reflect kung anong natutunan mo
