Den omfattande programvarustyrningen av funktionerna \u00e4r den fr\u00e4msta f\u00f6rdelen med denna digitala I\/O-modul, som har 48 digitala I\/O-kanaler, 3 16-bitars r\u00e4knare\/timers och 3 oberoende avbrottsing\u00e5ngar f\u00f6r PC-bussen.<\/p>\n

De 48 digitala I\/O-linjerna p\u00e5 Onyx-MM bygger p\u00e5 tv\u00e5 82C55-kretsar. De kan programmeras f\u00f6r ing\u00e5ng eller utg\u00e5ng i grupper om 8 linjer. B\u00e5de direkt- och strobe- (l\u00e5st) I\/O-l\u00e4ge st\u00f6ds, och alla I\/O-linjer \u00e4r anslutna till 10 k\u03a9 pull-up-motst\u00e5nd. <\/p>\n

De tre 16-bitars r\u00e4knarna\/timrarna \u00e4r baserade p\u00e5 en 82C54-krets. De styrs via ett konfigurationsregister p\u00e5 Onyx-MM (ut\u00f6ver det vanliga 82C54-konfigurationsregistret). R\u00e4knarens ing\u00e5ngar kan v\u00e4xlas mellan externa signaler, den inbyggda 4 MHz-klockoscillatorn eller r\u00e4knarens utg\u00e5ngar, allt under programvarustyrning. Genom att anv\u00e4nda utg\u00e5ngen fr\u00e5n en r\u00e4knare som ing\u00e5ng till en annan r\u00e4knare kan du koppla ihop r\u00e4knarna i programvaran f\u00f6r att skapa en 32-bitars eller 48-bitars r\u00e4knare. <\/p>\n

Onyx-MM har \u00e4ven programmerbara avbrottsfunktioner. Ett andra programvarustyrt register p\u00e5 kortet konfigurerar upp till tre avbrottslinjer p\u00e5 PC-bussen. Avbrott kan genereras av r\u00e4knar-\/timerutg\u00e5ngarna, digitala I\/O-linjer eller en extern ing\u00e5ngslinje. Detta g\u00f6r det m\u00f6jligt att anv\u00e4nda en r\u00e4knare f\u00f6r att generera bussavbrott med en programmerad periodisk frekvens, generera h\u00e5rdvaruavbrott under programvarukontroll eller generera avbrott som svar p\u00e5 en extern h\u00e4ndelse. <\/p>\n","protected":false},"excerpt":{"rendered":"
