Iprojekthi yeRaspberry Pi inikezelwe kutshanje ipleyiti entsha ebizwa "Raspberry Pi Pico W", eqhubeka nokuphuhliswa kwebhodi yePico encinci, exhotywe nge-RP2040 microcontroller yobunini.
Uhlelo olutsha lwahlulwa ngokudityaniswa kwenkxaso ye-Wi-Fi (2.4GHz 802.11n), isetyenziswe kwisiseko se-Infineon CYW43439 chip. Itshiphu yeCYW43439 ikwaxhasa iBluetooth yeClassic kunye neBluetooth Low-Energy, kodwa azikaqukwa ebhodini.
Namhlanje sazisa amalungu amathathu amatsha osapho lakwaPico. I-Raspberry Pi Pico W ixabisa i-$ 6 kwaye izisa i-802.11n inethiwekhi engenazintambo kwi-platform yePico, ngelixa igcina ukuhambelana kwepini epheleleyo kunye nomntakwabo omkhulu. I-Pico H (i-$5) kunye ne-Pico WH (i-$7) yongeza iiheader ezilayishwe kwangaphambili kunye ne-3-pin yethu entsha yokudibanisa i-debug kwi-Pico kunye ne-Pico W ngokulandelelana. I-Pico H kunye ne-Pico W ziyafumaneka namhlanje; Incopho WH iya kulandela ngo-Agasti.
Malunga neRaspberry Pico W
Itshiphu yeRP2040 ibandakanya iprosesa ye-ARM-Cortex-M0+ (133 MHz) ezimbini kunye ne-264 KB ye-RAM ekwibhodi (i-SRAM), isilawuli se-DMA, inzwa yeqondo lokushisa, i-timer, kunye nomlawuli we-USB 1.1.
Ibhodi iqulethe i-2 MB yememori ye-Flash, kodwa i-chip isekela ukwandiswa ukuya kwi-16 MB. Kwi-I / O, izibuko ze-GPIO (izikhonkwane ezingama-30, apho i-4 yabelwe igalelo le-analog), i-UART, i-I2C, i-SPI, i-USB (umxhasi kunye nomninimzi kunye nenkxaso yokuqalisa ukusuka kwi-UF2 ifomathi drives), kunye nee-PIO ezi-8 ezinikezelweyo zibonelelwa ngezikhonkwane ( Programmable I/O oomatshini boMbuso) ukudibanisa iiperipherals zakho. Amandla anokunikezelwa kuluhlu lwe-1,8 ukuya kwi-5,5 volts, ekuvumela ukuba usebenzise imithombo eyahlukeneyo yamandla, kubandakanywa ezimbini okanye ezintathu iibhetri ze-AA eziqhelekileyo okanye iibhetri eziqhelekileyo ze-lithium-ion.
Kubaphuhlisi be-C, ukukhutshwa kwanamhlanje kwePico SDK kubandakanya inkxaso yeenethiwekhi ezingenazingcingo. Isitaki sothungelwano sakhiwe malunga ne-lwIP kwaye sisebenzisa i-libcyw43 nguDamien George (wodumo lweMicroPython) ukunxibelelana netshiphu engenazingcingo. Ngokungagqibekanga, i-libcyw43 inelayisenisi yokungasetyenziswanga kurhwebo, kodwa abasebenzisi be-Pico W kunye naye nabani na ongomnye ophuhlisa imveliso yabo malunga ne-RP2040 kunye ne-CYW43439 baxhamla kwilayisenisi yosetyenziso lwasimahla.

Abasebenzisi beMicroPython banokukhuphela umfanekiso ohlaziyiweyo we-UF2 ngenkxaso yenethiwekhi yePico W.
Izicelo zinokudalwa kusetyenziswa iC, C ++ okanye iMicroPython. I-MicroPython port ye-Raspberry Pi Pico yalungiswa ngokubambisana nombhali weprojekthi kwaye ixhasa zonke iimpawu ze-chip, kubandakanywa ne-interface yayo yokudibanisa i-PIO izandiso.
Ukuphuhliswa kwechip RP2040 usebenzisa iMicroPython, indawo yenkqubo ehlanganisiweyo yaseThonny ilungisiwe. Izakhono ze-chip zanele ukuqhuba izicelo zokusombulula iingxaki zokufunda koomatshini, ukwenzela ukuphuhliswa kwayo i-port ye-framework ye-TensorFlow Lite ilungiselelwe. Ukufikelela kwinethiwekhi, kucetywa ukuba kusetyenziswe i-lwIP network stack, efakwe kwinguqulelo entsha ye-Pico SDK yophuhliso lwesicelo solwimi lwe-C, kunye nakwi-firmware entsha ye-MicroPython.
Le firmware ye-UF2 esiyenzela i-Pico W yinguqulelo eyahlukileyo ye-firmware ye-MicroPython ekhoyo yebhodi yethu yePico. Siza kwenza utshintsho kwindawo yokugcina iMicroPython kungekudala emva kokukhululwa.
Kwabo banomdla wokufumana isiqwenga okanye ezininzi, kufuneka bazi ukuba ixabiso lepleyiti entsha yi-6 yeedola, eziziidola ezimbini ngaphezulu kokhetho lokuqala.
Kwiindawo zesicelo, ukongeza ekwabelaneni ngeekhompyuter zeRaspberry Pi, ukuphuhlisa iinkqubo ezizinzisiweyo kunye neenkqubo zokulawula izixhobo ezahlukeneyo, iWi-Fi ibekwe njengeqonga lokudala izixhobo ze-Intanethi yezinto (i-Intanethi yezinto) ezinxibelelana kwenye. umnatha.
Gqibela ukuba unomdla wokwazi okungakumbi ngayo malunga nenqaku, unokujonga iinkcukacha Kule khonkco ilandelayo.
