Cos jak klawiaturka na PS/2 - na czym?

Antoni Gerc napisal(a):

A sa takie? Protokol PS/2 jest najzupelniej banalny i mozesz go zrobic softwarowo.

Wez AVR, na ktorym juz cos robiles.

Polecam AVR 90S2313 - bardzo prosty w programowaniu - dos³ownie przy pomocy kabelka. Oraz program MCS Basic AVR - wystarczy ci demo bo jedynym ograniczeniem jest wielko¶æ programu - 2 k a dok³adnie tyle pamieci ma ten procek. Basic jest banalny (sk³adnia) szybko go wiêc opanujesz w zakresie jaki ci jest potrzebny, poza tym masz tam wbudowane procedury do obs³ugi klawiatury PS2 :-) Wystarczy napisac jedn± instrukcjê i ju¿ czyta znaki :-D

Je¿eli za¶ musisz pisaæ w assemblerze polecam stronki (z epanorama.net):

A właśnie odnośnie kabelka. Czy jak zrobię coś identycznego jak to opisane na stronce

No to mam spoooro lektury i mam nadzieję, że pomyślnie zakończę ten projekt.

W programie MCS Bascom jest modu³ do programowania prcoesorów AVR - i w helpie znajdziesz opis programatora "Sample Electronics Programmer". Programator ten jak juz pisa³em to tylko przewody (¿adnej elektroniki :-) Dzia³a ¶wietnie - ak chcesz to przesle ci zdjêcia na Priv (mam zrobiony na uniersalce modu³ z malutki mikrokontrolerem AVR 90S2313 10 Mhz) z mo¿liwo¶ci± programowania z komputera. Po zaprogramowaniu nawet bez od³±czania procesor sam rusza i zaczyna dzia³aæ program - ¶wietna sprawa :-D
