| + | See teegi osa sisaldab Kodulabori koodrite kasutamise funktsioone. Koodrite lugemine on katkestuste põhine, st koodri pulsside lugemisega tegeleb väline katkestus koodri viigul. See tähendab, et globaalsele peavad olema katkestused lubatud (koodri initsialiseerimine lubab ka katkestused). | ||

| + | * **//void encoder_init(unsigned char index)//** \\ | ||
| + | Seadistab valitud koodri ja selle sisendviigud. Parameetrid: | ||
| + | * //index// - Koodri number. Väärtus 0 kuni 1. (Kodulabor III puhul 1-4) | ||
| + | |||
| + | * **//void encoder_reset_pulses(unsigned char index)//** \\ | ||
| + | Nullib valitud koodri ja käivitab loendamise. Parameetrid: | ||
| + | * //index// - Koodri number. Väärtus 0 kuni 1. (Kodulabor III puhul 1-4) | ||
| + | |||
| + | * **// | ||
| + | Koodri loendatud pulside arvu küsimine. Parameetrid: | ||
| + | * //index// - Koodri number. Väärtus 0 kuni 1. (Kodulabor III puhul 1-4) | ||
| + | * Tagastab pulsside arvu. | ||
