Zotsatira

Zizindikiro zotuluka zimaperekedwa kwa zolumikizira coaxial zomwe ziyenera kulumikiza bokosilo (cholumikizira chamitundu yamkuwa) ndi chipangizo chandamale, mwachitsanzo kamera. Pamene wolamulira alibe ntchito, zomwe zimatuluka pa coaxial ndi LOW (0.0 Volt). Pamene wolamulira ayamba kuwerengera, chizindikiro chotuluka chimayikidwa HIGH (3.3 Volt). Pambuyo pofika pamawerengedwe angapo, chizindikiro chotuluka chimatsikira ku LOW. Chizindikirochi chingagwiritsidwe ntchito kuyambitsa kuwerenga kwa kamera kapena kuchitapo kanthu mumtundu wina wa hardware. Ntchitoyi idzabwerezedwa kangapo.

Kutalika kwa siginecha yosinthira HIGH-LOW-HIGH ndi pafupifupi. 5 microseconds. Ndizotheka kutembenuza ma siginecha (HIGH = 0 V, LOW = 3.3 V).

Pamene wolamulira akuwerengera zizindikiro, LED1 idzayatsidwa. Kupanda kutero, wowongolera akakhala wopanda ntchito, LED1 imazimitsa. LED2 idzagwira ntchito mofananamo koma idzayatsa kokha ngati chizindikiro chotuluka chiri CHAKULU ndipo mwinamwake chidzazimitsidwa. Popeza nthawi yosinthira pakati pa HIGH ndi LOW ndi yayifupi kwambiri, ma LED onsewa amawoneka ofanana.

Nthawi yochedwa yokhazikika iyenera kukhala ma milliseconds 100 kuti muwone kusiyana.
Batani la RESET liyambitsanso chowongolera chomwe ndi njira ina yotulutsira chingwe cha USB. Mukayatsa, LED1 imayaka kasanu pomwe LED5 imakhala yoyaka nthawi zonse. Pambuyo poyambira, ma LED onse azimitsidwa.
