Izixhobo zokucwangcisa ezikhoyo
Into enika umdla ngosapho Bona Studio XIAO kukuba baxhasa iindidi ngeendidi zeendawo zophuhliso kunye neelwimi zeprogram, zivumela zombini ii-hobbyists kunye neengcali ukuba zidibanise ezi bhodi kwiiprojekthi zabo ngokulula.
Phakathi kwezona lwimi zisetyenziswa kakhulu kwiimodeli zenkqubo zezi:
- IsiArduino: Iklasikhi kwiprogram ye-microcontroller. Zonke iibhodi ze-XIAO ziyahambelana nale meko yenkqubo.
- IMicroPython: Kwabo bakhetha indlela elula nelula, iMicroPython isebenza ngokugqibeleleyo kwezi bhodi, ivumela inkqubo ekhawulezayo ngaphandle kwesidingo samathala eencwadi anzima.
- I-CircuitPython: Olu lwahlulo lwePython luyilelwe ngokukodwa i-microcontrollers, kwaye ivumela ukuba kube lula kakhulu, kodwa kunye nophuhliso olunamandla.
Ubungakanani obuncinci kodwa ukusebenza kakuhle
Njengoko igama labo libonisa, microcontroller XIAO bancinci ngokumangalisayo, kunye nemilinganiselo ye-20 x 17.5 mm kuphela. Le yenye yeenzuzo zayo eziphambili ngaphezu kwamanye amaqonga, kuba ivumela ukusetyenziswa kwayo kwiindawo ezincinci. Ngaphezu koko, ngenxa yoyilo lwazo olusebenzayo, ukusetyenziswa kwamandla kwezi bhodi kuncinci, okwenza ukuba zilungele iiprojekthi ezixhaswe ziibhetri ezihlala ixesha elide.
Enye ingcaciso ephawulekayo kukuba iibhodi ezininzi zibandakanya izibuko kuyilo lwazo. Uhlobo lwe-C lwe-USB, eyenza kube lula ukucwangcisa kunye nokudibanisa nezixhobo ezahlukeneyo. Olu luphawu oluthandwa ngabaphuhlisi abaqalayo kunye nabaphambili.
Ukongeza kubukhulu babo kunye nokusetyenziswa kwamandla aphantsi, iibhodi ze-XIAO zikwabandakanya ii-LED ezicwangcisiweyo eziququzelela ukuchongwa kwamazwe kunye nokuvumela umphuhlisi ukuba enze ukusebenzisana okubonakalayo ngaphandle kwesidingo sezibonelelo ezongezelelweyo.
Kubalulekile ukukhankanya ukuba, nangona iipleyiti ezihlangeneyo kakhulu, i ujongano abalunikezelayo lugqibelele. Phantse zonke iimodeli zinezikhonkwane ezinokusetyenziselwa i-PWM, i-ADC, i-I2C, i-SPI kunye ne-UART. Oku kuvula uluhlu lwamathuba onxibelelwano kunye nolawulo lweenzwa, iimotor, iziboniso kunye nokunye okuninzi.
Yeyiphi onokuyikhetha kwiprojekthi nganye?
Uluhlu olubanzi lwentsapho ye-XIAO lunokuba lukhulu ukuba awuqinisekanga ukuba yeyiphi imodeli onokuyikhetha. Ngokubanzi, nganye i-microcontrollers yenzelwe uhlobo oluthile lweprojekthi. Umzekelo:
- Ukuba ufuna i-microcontroller elula, kodwa eneempawu ezilungileyo, i XIAO SAMD21 Lolona khetho lubalaseleyo kwiiprojekthi zokuqala.
- Kwiiprojekthi ezingenazintambo, i XIAO NRF52840 o XIAO ESP32C3 Banikezela ngeBluetooth kunye neWi-Fi amandla.
- Ukuba ukufunda ngomatshini yinto yakho, i XIAO ESP32S3 okanye inguqulelo Sense Zezona zicetyiswayo.
