Okusajingijolo Pi Pico ibhodi le-microcontroller elisha elenziwe yiRaspberry Pi Foundation. Umkhiqizo omusha ukuthi ijoyina ekhona futhi okufana kakhulu I-Arduino kune-SBC. Ngaphezu kwalokho, inesinye isimanga esikhulu esimangaze wonke umuntu, futhi idlula ubukhulu bayo obuncane, ukusebenza kahle kwamandla amakhulu, noma intengo yayo engu- $ 4 kuphela.
Futhi ukuthi i-Raspberry Pi Foundation iguqule, okungenani okwesikhashana, yaba i-fabless, yaklama i-chip yayo. Imayelana ne- I-SoC RP2040. Lokho wukuthi, ngalesi sikhathi, kabasebenzisanga ama-Broadcom chips njengakwamanye amabhodi, kepha baziklanyelile bona ngokwabo. Sizobona ukuthi ngokuzayo balandela lo mkhuba ofanayo kwamanye amapuleti noma ngabe bekuyinto ethize kuphela ...
I-SoC RP2040
El I-RP2040 yi-chip yokuqala eyenzelwe iRaspberry Pi Foundation. Idizayini eyenzelwe ekhaya ukuthuthukisa leli bhodi elincane kakhulu nelincane kakhulu futhi lenzelwe amaphrojekthi lapho usayizi nokusetshenziswa kubalulekile, njengokufaka okuthile okushumekiwe noma okushumekiwe kurobhothi, imboni, ezezimoto, izinhlelo zezokwelapha, iziteshi zezulu, njll.
Ngaphandle kwalokho okushiwo eminye imidiya (ngisho neminye ebalulekile nebabazekayo), akuyona i-chip eyenziwe yibo, eyenzelwe bona kuphela. I-SoC eyenzelwe iqembu lethu ngokukhethekile Ama-ASIC futhi lokho kuholele kule IC.
Okusho ukuthi, azizange ziguqulwe zibe yi-IDM, kepha ziyizinganekwane nje kuphela ezithumele ukwakheka kwazo ukuthi kwenziwe esisekelweni TSMC. Kulezi zimboni kusetshenziswe inqubo engama-40nm ekwenzeni kwabo. Futhi, iyi-node engabonakala ngathi ingeyakudala impela, kepha lobo buchwepheshe be-lithography bungaphezu kokwanele kwale phrojekthi futhi benza umsebenzi wayo kahle kakhulu.
Ukubuyela ekwakhiweni kwe-rp2040 SoC enika amandla le Raspberry Pi Pico, iyip chip lapho ama-cores angakhiwanga khona ekuqaleni, kepha kunalokho bakhethe ukusebenzisa ama-Arm's IP cores. Ngokuqondile, kusetshenzisiwe ama-ARM amabili Cortex M0 + usebenza ku-133Mhz. Ngaphezu kwalokho, ifakwe i-264 KB ye-RAM, ne-2MB ye-flash.
Konke akuhloselwe ukusebenzisa uhlelo olusebenzayo njengeLinux (noma ezinye), njengoba kwenzeka kwamanye amabhodi we-SBC, kepha iRaspberry Pi Pico ingasebenza kuphela imidwebo noma izinhlelo ezibhalwe ngezilimi ezinjenge C / C ++ noma i-MycroPython. Lapho nje uwabhala ku-PC yakho, angadluliselwa ebhodini nge-microUSB ukuze uphiko lwe-MCU, noma i-microcontroller, lukusebenzise.
Okokugcina, angifuni ukubeka eceleni isibizo isetshenzisiwe, futhi igama elithi RP2040 linesizathu salo:
- RP: imele i-Raspberry Pi
- 2: inani lama-cores.
- 0: uhlobo loqobo (M0 +).
- 4: log2 (RAM / 16kB).
- 0: log2 (non-volatile or flash / 16kB), uma kungu-0 kungenxa yokuthi kusebhodini.
Lokhu kungabonakala kuyisiphukuphuku, ikakhulukazi uma kubhekwa ukuthi okwamanje kune-SoC eyodwa kuphela edizayinwe yibo. Kepha kungahle kusikisele ukuthi iRaspberry Pi Foundation kungenzeka yakha ama-SoC amaningi ngokuzayo...
Imininingwane engaphezulu - Idatha yemininingwane RP2040
Mayelana nebhodi le-Raspberry Pi Pico
Ipuleti elisha Okusajingijolo Pi Pico igcina izimanga ezimnandi, yize incane. Futhi ngentengo engu- $ 4 kuphela, eyenza ukuthi ibe ngamabhodi we-microcontroller athengeka kakhulu emakethe.
Ukuphuma
Ngokuqondene ne imininingwane yezobuchwepheshe kanye nokucaciswa, nayi yonke imininingwane yepuleti:
- I-SoC: I-RP2040 yakhelwe e-UK yiqembu elisebenza nge-ASIC lokuklama le-Raspberry Pi Foundation.
- I-DualCore ARM Cortex-M0 + enemvamisa yewashi enamandla kuze kufike ku-133Mhz.
- 264 kB yememori ye-SRAM
- 2MB yememori ebhodini.
- Ngokusetshenziswa okuphansi kakhulu nezindlela zokulala nokulala.
- Ukuxhumana: i-microUSB ngokuxhaswa kwe-USB 1.1 Host
- Ukuhlela: Hudula bese uphonsa usebenzisa izilimi ezinjenge-C / C ++ ne-MicroPython.
- I-GPIO: Amaphini angama-26 asebenzayo
- Ezinye izikhonkwane: 2x SPI, 2x I2C, 2x UART, 3x 12-bit ADC, 16x iziteshi I-PWM.
- Ukudla: 3.3 V
- Okuningi: inzwa yokushisa, imitapo yolwazi esentantayo esheshayo ku-ROM, kanye ne-8x PIO (Ehlelwe i-O / O) ukuze ikwazi ukuvumelanisa ibhodi ukuze isekele okuphelele, njll. Isibonelo, nge-PIO kungalungiswa ukulingisa i-VGA, umsindo, umfundi wekhadi le-SD, njll.
- Tamaño: 51x21mm
- Intengo: 4 $ (Thenga)
Ungaqala kanjani ukwenza izinhlelo
I-Raspberry Pi Pico entsha ihlelwe kusetshenziswa i-C / C ++ SDK noma imbobo esemthethweni yeMicroPython, kuya ngokuthi ukhetha ukusebenzisa ulimi olulodwa noma olunye kumaphrojekthi akho. Ngaphezu kwalokho, lolu hlelo lulayishwa kalula:
- Mane nje ubambe inkinobho ye-BOOTSEL ebhodini
- Ukuxhuma ikhebula le-microUSB kwi-PC (i-Linux, iWindows, noma i-MacOS, futhi ungahle uhlele kusuka ku-Raspberry Pi 4)
- Ngemuva kwalokho inkinobho ye-BOOTSEL iyadedelwa bese i-PC izofaka iyunithi entsha ebizwa nge-RPI-RP2 kube sengathi iyipendrive.
- Manje, kufanele nje uhudule ifayela lekhodi le-UF2 kuyunithi lememori futhi lizolayisha.
- IRaspberry Pi Pico izoqala kabusha futhi iqale ukusebenzisa uhlelo.
Ngaphezu kwalokho, une- ifayela INDEX.HTM ngaphakathi kweyunithi futhi lokho kuzokukhombisa imibhalo esemthethweni kuwebhusayithi yeRaspberry Pi. Elinye ifayela le-INFO_U2F.TXT liqukethe imininingwane mayelana nebhodi, efana nenguqulo ye-bootloader.
