Uma sikhuluma nge-Raspberry Pi, kulula ukucabanga ukuthi sibhekisela ebhodini lokuthuthukiswa "elikhulu", leli sonke noma iningi lethu esilaziyo. Kepha iRaspberry Pi Foundation isanda kukhipha isiphakamiso sesibili esibizwa Okusajingijolo Pi Pico okuyinto ngobukhulu ithakazelisa kakhulu ukusetshenziswa okuthile. Okuningi kakhulu uma uhambisana nakho okunye izesekeli ezinelukuluku kakhulu nezijabulisayo osekuvele kukhona.
Iyini i-Raspberry Pico
I-Raspberry Pi Pico, uma ungakayazi, iyibhodi lokuthuthukisa elihlangene kakhulu. Yethulwe ekuqaleni kuka-2021 ngenhloso yokunikeza enye inketho kulabo abafuna ukwenza amaphrojekthi lapho kudingeka khona izinto ezincane.
Ngokunengqondo, iqiniso lokuthi iyibhodi elihlangene kakhudlwana lisho ukuzidela, njengezingxenye ezithile nokuxhumana okungaqhathaniswa neRaspberry Pi 4. Noma kunjalo, i- izici zobuchwepheshe zalesi Raspberry Pi Pico awababi neze:
- I-RP2040 microcontroller yakhelwe i-Raspberry Pi
- 0 Mhz Dual Core ARM Cortex M133+
- 264 KB SRAM
- 2MB inkumbulo ye-Flash engaphakathi
- I-USB 1.1 enokwesekwa komsingathi
- Imodi yamandla aphansi kanye ne-hibernation
- Hudula bese uwisa izinhlelo usebenzisa isitoreji esiningi se-USB
- 26 pin multifunction GPIO
- 2 SPI, 2 I2C, 2 UART, 3 12-bit ADCs, 16 iziteshi ze-PWM
- Ithempelesha inzwa
- Iwashi elisebhodini elinembile
- Imitapo yolwazi yendawo entantayo eku-chip
- 8 izimbobo ze-I/O (PIO) ezihlelekayo
Ukubheka lokho i-Raspberry Pi Pico ibiza kancane ama-euro angu-5, Iqiniso liwukuthi akukubi nhlobo futhi kunganikeza ukudlala okuningi uma usuvele unolwazi noma unamakhono anele kanye nesifiso sokulandela amaphrojekthi amaningi asevele eqala ukujikeleza ku-intanethi.
Izesekeli ezihamba phambili zeRaspberry Pi Pico
I-Raspberry Pi Pico ibhodi lokuthuthukisa ongenza ngalo izinto eziningi. Okokuqala, sibonga izikhonkwane zayo ezingama-26 ze-GPIO kanye nokokufaka okuthathu kwe-analog ingasetshenziselwa amaphrojekthi we-IoT (I-inthanethi Yezinto), i-automation yasekhaya noma ngisho nokudala amadivaysi emidlalo amancane.
Kuyiqiniso ukuthi kwezinye izinhlobo zokusetshenziswa akuzona ezifanele kakhulu, ngoba leyo enye inguqulo yayo ephakeme futhi enokuxhumana okwengeziwe (isifundi sekhadi le-microSD, ukuphuma kwe-HDMI, i-USB, njll.), kodwa uma uhambisana nayo namamojula athakazelisayo. Uzobona ukuthi izinto ziyashintsha.
I-PicoSystem
Lokhu ngokungangabazeki kuwukuphelelisa okuhle futhi kungenye yamamojula amahle kakhulu esizowabona esikhathini eside se-Raspberry Pi Pico. Ngaphezu kwalokho, cishe ufuna eyodwa ngokushesha nje lapho wazi ngayo.
I-PicoSystem iyinhlangano yonke-in-one okuhlanganisa isikrini, i-crosshead yokulawula nezinkinobho ezine ongakwazi ngazo ukushintsha i-Raspberry Pi Pico ibe ikhonsoli encane yephaketheni. Ukuze ujabulele igeyimu yezikhathi ezithile lapho unemizuzu embalwa yokuzilibazisa.
Peak Scroll
Le mojula encane enobukhulu obufanayo ne-Raspberry Pi Pico inikeza ingqikithi Ama-LED amhlophe angu-119 ahlelwe ku-matrix engu-17 x 7. Lezi zingalawulwa ngazodwana kanye nezinkinobho zokuthinta ezine ezizivumela ukuthi zihlelwe ngaphambilini ukuze zenze izenzo ezihlukile, njengokuzivula nokuzivala noma izindlela zokukhanyisa ezihlukile ezilandela amaphethini asungulwe ngaphambilini.
I-Unicorn Peak
Ngendlela efanayo naleyo edlule, le moduli I-Unicorn Peak ihluke kwezinye ukuthi esikhundleni sama-LED amhlophe akhona Ama-RGB LED. Yiqiniso, lokhu kunikeza ukudlala okwengeziwe futhi kukuvumela ukuthi udale amaphrojekthi noma uwasebenzise ukuze ubonise izinhlobo ezahlukene zezaziso ngokusebenzisa ikhodi yombala engasetshenziswa.
Kokunye, ziyafana ngokwenyama endabeni yobukhulu futhi iphinde inikeze izinkinobho zokuthinta ezine ezingacushwa ngokuya ngezidingo zomsebenzisi kanye nemisebenzi afuna ukuyabela yona.
I-Peak Audio
Le enye imojula eyakhelwe i-Raspberry Pi Pico ikuvumela ukuthi udale isikhulisi somsindo esithuthukisa umuzwa ozwakalayo lapho usebenzisa ama-headphone ngedivayisi yakho, kungakhathaliseki ukuthi kuyini, uma ngaphambili udlulise isignali yokuphuma kuyo. Lokhu kungenxa yokuthi a I-DAC Ehlanganisiwe okuyinto, njengabanye emakethe, esiza ukugcwalisa izikhala zalabo abahlanganiswe, ikakhulukazi, abanye abadlali abaphathekayo.
Ikhiphedi yekhiphedi ye-RGB ephezulu
Nge 4 x 4 inkinobho ye-matrix ekhanyiswa ngama-RGB LED Le mojula inikeza ikhibhodi engacushwa ngendlela umsebenzisi afuna ngayo, isibonelo, ukusebenza njenge lawula i-usb yangokwezifiso ongaqalisa ngazo izenzo ezinkulu ezitholakala ezinhlelweni eziningi ezifana nokusakaza-bukhoma noma imidlalo.
isibonisi esiphezulu
I-Pico Display yi-a 1,14″ IPS LCD isikrini enikeza isixazululo Amaphikseli ayi-240 × 135. Incane, iyiqiniso, kodwa inombala futhi ihambisana nezinkinobho ezine kanye ne-RGB LED enganikeza umdlalo omningi. Uma udinga isibonisi esincane ukuze ubonise ulwazi, inketho efanelekile.
Isibonelo, cabanga ukuyisebenzisela ukudala uhlobo oluthile lwesilawuli esizenzakalelayo sasekhaya ongakwazi ngaso ukusebenzisana namanye amadivayisi ekhaya futhi isimo saso sikhonjiswe esikrinini. Impela ubona ukusetshenziswa okuningi kwakho uma usuvele unolwazi kule phrojekthi nge-Raspberry Pi.
Ukuqalisa nge-Raspberry Pi Pico
Wonke lawa mamojula anelukuluku angawa I-Pimoroni futhi njengoba ungabona baveza imibono eminingi. Kodwa uma ubuza ukuthi ungaqala kanjani ukwenza amaphrojekthi ahlukahlukene nge-Raspberry Pi Pico, kungcono ukukwenza nge- Amadokhumenti asemthethweni anikezwe i-Raspberry Pi Foundation. Lokho kuzokusiza ukuthi wazi ihadiwe, ukuxhumana kwayo futhi ubone izibonelo zokuqala ukuze wazi amandla ayo kanye namathuba.
Kusukela lapho, kuyindaba yokuqala ukuphenya nokufaka izinkundla ezikhethekile lapho inqwaba yabasebenzisi bechaza ukuthi benzani, banikeze izeluleko nokunye okuningi ukuze bazuze ngokugcwele kule divayisi ethile.
