Tlhaloso
STEVAL-L9800 ke sesebelisoa se etselitsoeng ho lekola sesebelisoa sa matla a bohlale sa L9800, se entsoeng ke STMicroelectronics ka theknoloji e tsoetseng pele ea BCD. L9800 ke IC-channel 8 e nang le bakhanni ba LS ba robeli ba etselitsoeng lisebelisoa tsa likoloi (li-LED le li-relay) 'me li tsamaisana le meroalo e hanyetsanang, e kenyang letsoho le ea capacitive. Sesebelisoa se fana ka lits'ebetso tse tsoetseng pele tsa tlhahlobo le ts'ireletso joalo ka bokhuts'oane ho GND, mojaro o bulehileng, overcurrent, le ho lemoha mocheso o feteletseng. Likanale tse 8 tse hlahisoang li ka tsamaisoa ke SPI kapa ke 2 e inehetseng e ts'oanang e kenyang e ka amahanngoang le liphetho tse fapaneng ka lebaka la "multiplexer" e ka khonehang. Ts'ebetso e bobebe ea lapeng e boetse e hlahisoa, e lumellang ts'ebeliso ea bakhanni ba 2 ba khethiloeng maemong a itseng a phoso, joalo ka phoso ea SPI, phoso ea microcontroller, kapa phepelo ea UV. Tšebelisano ea Daisy chain, leha e na le 8-bit SPI, ea fumaneha. Sesebelisoa se ka netefatsa ts'ebetso maemong a cranking ho ea ho VBATT = 3 V le hona joale e tlase haholo e khutsitseng maemong a SLEEP.
Sesebelisoa sa serial peripheral interface (SPI) se sebelisetsoa ho laola le ho hlophisa meroalo le sesebelisoa. Ho fanoe ka maikutlo a boemo ba mesebetsi eohle ea tlhahlobo.
Ho na le lithakhisa tse peli tsa ho kenya tse fumanehang bakeng sa taolo e tobileng le PWM: tsena li hokahane le liphetho tse peli tse hlalositsoeng ka mokhoa o ikhethileng, empa 'mapa o eketsehileng kapa o fapaneng oa tlhahiso o ka laoloa ke SPI. Ka lebaka la li-connectors tsa katoloso, STEVAL-L9800 e lumella taolo e feletseng ea L9800 ea puisano ea puisano (SPI) le ho kenya letsoho ka mokhoa o ts'oanang.
Sethala sa tlhahlobo se ka boela sa laoloa ka graphical user interface (GUI) ho AEK-MCU-C1MLIT1 hardware interface.
