I-Raspberry Pi Foundation isungule imveliso entsha. Imalunga ne- I-Raspberry Pi Pico, I-SBC entsha enexabiso eliphantsi ejoyina ezikhoyo. Ngaloo nto, umnikelo wangoku uqinisiwe, kunye ne-Raspberry Pi 4 kunye nePi Zero, okanye iPi 400. Ngoku, ifomathi entsha inobungakanani obuncitshisiweyo, kwaye ngexabiso elothusayo: malunga ne- $ 4.
Kule meko yi- MCU okanye microcontroller, isisombululo esilula nesincitshisiweyo sokuphumeza yonke into efunekayo ukuqhuba inkqubo efakelweyo kwaye siyisebenzise kwiiprojekthi apho ubukhulu kunye nokusetyenziswa kubalulekile, njengeeprojekthi zonyango, ezemoto, ezamashishini, iirobhothi, izikhululo zemozulu, njl.
Unokucinga ukuba ayizondaba zimnandi ezi, kwaye kuyinyani ukuba iipleyiti ezifanayo ezincitshisiweyo sele zikhona. Kodwa iindaba ezimnandi zezinye. Inkqubo ye- I-Raspberry Pi Foundation igcine isimanga. Kwaye kuyenzeka ukuba ibe ngumyili ongenachaphaza weetshipsi zayo, ezinje nge-SoC ebandakanya iRaspberry Pi Pico.
I-SoC eyilwe ngokwabo kwaye yathiywa ngegama RP2040. Inkqubo yokulungisa ayenzelwanga kwasekuqaleni, endaweni yoko sikhethe ii-cores ezinelayisensi kwiArm. Ngokukodwa, ii-cores ze-ARM Cortex M0 + kwi-133Mhz zenziwe. Kunye nabo, i-264 KB ye-RAM kunye ne-2MB yokugcina i-flash ziye zaphunyezwa, kunye ne-PIO (eyenzelwe i-I / O) iyunithi yokulingisa iindawo ezinje ngezo zamakhadi e-SD, i-VGA, njl.
Lumka! Kungenxa yokuba khange babe yi-MDI ubusuku bonke, njengoko amanye amajelo eendaba abonakalayo abonakala ebonisa. Ndiyaphinda ukuba ayinantsingiselo, bazilinganisela ngokwabo kuyilo, hayi ukuvelisa. Ngapha koko, i-Raspberry Pi Pico chip yenziwa kwifayile ye- Ukufunyanwa kweTSMC, kunye ne-40nm node. Kwaye kuya kufuneka sibone ukuba ngaba le yinto ye-SoCs yexesha elizayo, okanye ukuba yinto ethile ethile kwaye baya kuqhubeka nokusebenzisa i-Broadcom ...
Ngendlela, itekhnoloji ye Umhla we-lithographEwe ayifuni ngaphezulu kokunikwa izinto ezilula zale chip. Yenzelwe into eyenzelweyo, ingaphezulu kokuhlangana.
Ngokuphathelele kwinkqubo yokusebenza, inyani yile ngekhe ukwazi ukufaka iLinux okanye abanye, njengakwezinye ii-SBCs. Hayi, apha unokufaka ngokulula iinkqubo eziza kusebenza. Oko kukuthi, ngaloo ndlela kuyafana nebhodi yeArduino.
Ungabhala imizobo kwiilwimi zenkqubo ezinje C okanye iMicroPython kwi-PC kwaye uzilayishe kwi-microUSB kwimemori yeRaspberry Pi Pico yakho. Ke, i-microcontroller iya kuba nakho ukuyenza kwaye isebenze kwizikhonkwane ze-GPIO.
Ngokucacileyo, sukulindela izibonelelo ezinkulu. Yi ipleyiti encinci kuba ijolise kudidi oluthile lwezicelo. Ukongeza kokungakwazi ukufaka i-OS, uya kuphinda ubalekele kwiintsilelo ngokunxibelelana ngaphandle kwamacingo ngenxa yesayizi encinci.
