Mam ogolne pytania o mikrokomputery jednoukladowe 8bit.:

EEPROMem np 2 lub 4 kB? (wiem, ze z epromami byly),

Jednym slowem chodzi mi najprostszy, ale latwy do
zaprogramowania i tani. Szybkosc jest sprawa drugorzedna.

- czy jest wersja CMOS,
- jakie jest oznaczenie,
- jaka jest cena.

Od pewnego czasu nie ma problemu - Atmel, robi serie klonow 8051,
pod numerkami 89C51, 89C52, 89C2051 i 89C1051.

Ceny przystepne (~20zl za 89c51), szeroko dostepne w PL, firma
publikuje schemat programatora - zlote czasy dla hobbystow.

Przesylam ci kod zrodlowy prostego programatora AT20C51 w turbo pascalu w
komentarzach znajdziesz adres WWW gdzie jest cala reszta tzn.schemat i
rysunek plytki, rysunek plytki mam w formacie Acad13(DWG) jezeli cie
interesuje przyslij poczte.Jest to prosty programator (ale dziala)
podlaczany do portu rownoleglego drukarki.W prosty sposob mozna
poeksperymentowac.
Pozdrowienia
