Jedn\u00e1 se o n\u00e1hradu klasick\u00e9ho p\u00e1kov\u00e9ho ovlada\u010de (joysticku) ovlada\u010dem s jednotliv\u00fdmi sm\u011brov\u00fdmi tla\u010d\u00edtky. Tla\u010d\u00edtka jsou rozm\u00edst\u011bna ve stylu QAOPM (tla\u010d\u00edtka na kl\u00e1vesnici po\u010d\u00edta\u010de). Tento joystick je funk\u010dn\u011b 100% kompatibiln\u00ed s „normou“ STICK4004\/482, tedy se v\u0161emi existuj\u00edc\u00edmi hrami pro PMD-85, kter\u00e9 joystick podporuj\u00ed.<\/p>\n

Tento projekt je sice u\u0161it\u00fd na m\u00edru PMD-85, ov\u0161em plo\u0161n\u00fd spoj umo\u017e\u0148uje zjednodu\u0161en\u00e9 osazen\u00ed, kompatibiln\u00ed s ATARI joystickem. Proto\u017ee joystick pro PMD-85 pou\u017e\u00edv\u00e1 vnit\u0159n\u00ed sign\u00e1l v\u00fdb\u011bru (PC0 nebo PC4 na portech GPIO), je od tohoto sign\u00e1lu odvozeno rozsv\u00edcen\u00ed zelen\u00e9 LED na joysticku, kter\u00e1 tak indikuje, \u017ee dan\u00fd joystick je aktivov\u00e1n (nutn\u011b to v\u0161ak nemus\u00ed znamenat, \u017ee jej hra pou\u017e\u00edv\u00e1).<\/p>\n

Ve verzi pro PMD-85 je nutno pou\u017e\u00edt 11-\u017eilov\u00fd kabel. V nouzi lze sice o\u017eelet 3 vodi\u010de a zapojit kabel pouze 8-\u017eilov\u00fd, ov\u0161em p\u0159ijdeme o indikaci, \u017ee joystick je hrou aktivov\u00e1n a d\u00e1le nebudou zapojeny pull-up odpory R4..R8. Tyto odpory v\u011bt\u0161inou stejn\u011b zapojeny nejsou a joysticky funguj\u00ed, tak\u017ee to by nakonec nemusel b\u00fdt ani tak velik\u00fd probl\u00e9m.<\/p>\n

Proto\u017ee PMD-85 nem\u00e1 na konektorech GPIO vyvedeno +5V, je pro pull-up rezistory a nap\u00e1jen\u00ed LED pou\u017eito v\u00fdstup\u016f u\u017eivatelsky dostupn\u00fdch hradel na t\u011bchto konektorech. Dv\u011b hradla nap\u00e1j\u00ed pull-up rezistory, t\u0159et\u00ed hradlo nap\u00e1j\u00ed LED. Hradla jsou ve skute\u010dnosti typu OPEN-COLLECTOR, tak\u017ee se na v\u00fdstupn\u00edm nap\u011bt\u00ed nepod\u00edl\u00ed. Maj\u00ed tam v\u0161ak zapojeny vlastn\u00ed pull-up rezistory 3k3, co\u017e je pro na\u0161i aplikaci dostate\u010dn\u00e9.<\/p>\n
