I-Raspberry Pi Pico yibhodi entsha ye-microcontroller eyilwe yiRaspberry Pi Foundation. Imveliso entsha ethi ijoyina esele ikho kwaye yeyiphi efana nayo Arduino kune-SBC. Ukongeza, inesinye isimanga esikhulu esothuse wonke umntu, kwaye iya ngaphaya kobungakanani bayo obuncinci, ukusebenza kakuhle kwamandla, okanye ixabiso layo leedola ezi-4 kuphela.
Kwaye iRaspberry Pi Foundation itshintshile, ubuncinci okomzuzwana, ibe yinto engenamveliso, iyila eyayo i-chip. Imalunga nayo I-SoC RP2040. Oko kukuthi, ngeli xesha, khange basebenzise iichips zeBroadcom njengakwezinye iibhodi, kodwa bayile ngokwabo. Siza kubona ukuba kwixa elizayo bayayilandela le ndlela inye kwezinye iipleyiti okanye ukuba ibiyinto ethile kuphela ...
I-SoC RP2040
El I-RP2040 sisixhobo sokuqala esenziwe yiRaspberry Pi Foundation. Uyilo olwenziwe ekhaya ukuphucula le bhodi incinci kunye ne-ultra-thin kwaye iyilelwe iiprojekthi apho ubukhulu kunye nokusetyenziswa kubalulekile, njengokufakwa okungaphakathi okanye okufakwe ngaphakathi kwiirobhothi, kwimizi-mveliso, kwezithuthi, kwezonyango, kwizikhululo zemozulu, njl.
Ngaphandle kwento ethethwa ngamanye amajelo eendaba (nokuba ibalulekile kwaye inesidima), ayisiyiyo chip eyenziwe ngabo, eyilwe kuphela ngabo. I-SoC eyilelwe liqela lethu elikhethekileyo Ii-ASIC kwaye oko kubangele kule IC.
Oko kukuthi, azange ziguqulwe zenziwe i-IDM, kodwa ziintsomi ezithumele uyilo lwazo ukuba lwenziwe kwisiseko TSMC. Kule fektri inkqubo ye-40nm isetyenziselwe ukwenziwa kwayo. Ewe, yindawo ebonakala ngathi yeyamandulo, kodwa itekhnoloji ye-lithography ingaphezulu ngokwaneleyo kule projekthi kwaye iwenza kakuhle umsebenzi wayo.
Ukubuyela kuyilo lwe-rp2040 SoC egunyazisa le Raspberry Pi Pico, yi-chip apho ii-cores zingakhange zenziwe kwasekuqaleni, kodwa bakhethe ukusebenzisa ii-Arm's IP cores. Ngokukodwa, isebenzise ezimbini ze-ARM Cortex M0 + usebenza e133Mhz. Ukongeza, ikwaxhotyisiwe nge-264 KB ye-RAM, kunye ne-2MB ye-flash.
Zonke azizimiselanga ukuqhuba inkqubo yokusebenza njengeLinux (okanye ezinye), njengoko kusenzeka kwezinye iibhodi ze-SBC, kodwa iRaspberry Pi Pico inokuqhuba kuphela imizobo okanye iinkqubo ezibhalwe ngeelwimi ezinje C / C ++ okanye iMycroPython. Nje ukuba uzibhale kwi-PC yakho, zinokudluliselwa ebhodini nge-microUSB ukuze iyunithi ye-MCU, okanye i-microcontroller, ibaphumeze.
Okokugqibela, andifuni ukubeka ecaleni igama lokutyunjelwa isetyenzisiwe, kwaye igama elithi RP2040 linesizathu:
- RP: imele iRaspberry Pi
- 2: inani lamakhonkco.
- 0Uhlobo oluphambili (M0 +).
- 4: log2 (RAM / 16kB).
- 0: log2 (engekho volatile okanye iflash / 16kB), ukuba ngu-0 kungenxa yokuba ikwibhodi.
Oku kunokubonakala kusisiyatha, ngakumbi xa ucinga ukuba ngoku inye kuphela i-SoC eyilwe ngabo. Kodwa inokubonisa ukuba iRaspberry Pi Foundation inakho Yila ii-SoCs ezininzi kwixa elizayo...
Iinkcukacha ezithe xaxe - Iphepha ledatha RP2040
Malunga nebhodi yeRaspberry Pi Pico
Isitya esitsha I-Raspberry Pi Pico igcina isimanga esimnandi, ngaphandle kobungakanani bayo obuncinci. Kwaye kuphela ngexabiso le- $ 4, eyenza ukuba ibe yenye yeebhodi ze-microcontroller ezifikelelekayo kwimarike.
Ukuphuma
Ngokuphathelele iinkcukacha kunye nokubalulwa, Nazi zonke iinkcukacha zepleyiti:
- SoCI-RP2040 eyilelwe e-UK liqela elisebenzayo le-ASIC yoyilo lweRaspberry Pi Foundation.
- I-DualCore ARM Cortex-M0 + eneewotshi ezinamandla ezinamandla ukuya kuthi ga kwi-133Mhz.
- 264 kB yememori ye-SRAM
- 2MB yememori ebhodini.
- Ukusetyenziswa okuphantsi kakhulu kunye neendlela zokulala nokulala.
- Unxibelelwano: microUSB ngenkxaso ye-USB 1.1 Host
- Inkqubo: Tsala kwaye ulahle usebenzisa iilwimi ezinje ngeC / C ++ kunye neMicroPython.
- GPIO: Iipini ezingama-26 ezininzi
- Ezinye izikhonkwane: 2x SPI, 2x I2C, 2x UART, 3x 12-bit ADC, 16x amajelo PWM.
- Ukutya: 3.3 V
- Ngakumbi: Isenzisi seqondo lobushushu, iilayibrari ezinendawo yokudada ekhawulezileyo kwiROM, kunye ne-8x PIO (enokucwangciswa I / O) ukuze ikwazi ukumelana nebhodi ukuze ixhase iipheripherali, njl. Umzekelo, nge-PIO inokuqwalaselwa ukuba ilingise i-VGA, isandi, umfundi wekhadi le-SD, njl.
- Tamaño: 51x21mm

Uqala njani inkqubo
I-Raspberry Pi Pico entsha icwangcisiwe isebenzisa i-C / C ++ SDK okanye izibuko elisemthethweni le-MicroPython, kuxhomekeke ekubeni ukhetha ukusebenzisa ulwimi olunye okanye olunye kwiiprojekthi zakho. Ukongeza, inkqubo ilayishwa ngokulula:
- Ngokugcina nje iqhosha leBOOTSEL ebhodini
- Ukuqhagamshela intambo ye-microUSB kwi-PC (iLinux, Windows, okanye iMacOS, kwaye unokude wenze nenkqubo kwiRaspberry Pi 4)
- Emva koko iqhosha le-BOOTSEL liyakhutshwa kwaye i-PC iya kuyinyusa iyunithi entsha ebizwa ngokuba yi-RPI-RP2 ngokungathi sisigqibo.
- Ngoku, kuya kufuneka urhuqe ifayile yekhowudi ye-UF2 kwiyunithi yememori kwaye iya kulayisha.
- I-Raspberry Pi Pico iya kuqalisa kwakhona kwaye iqale ukuqhuba inkqubo.
Ukongeza, unefayile ye- ifayile INDEX.HTM ngaphakathi kweyunithi kwaye iya kukubonisa amaxwebhu asemthethweni kwiwebhusayithi yeRaspberry Pi. Enye ifayile ye-INFO_U2F.TXT iqulethe ulwazi malunga nebhodi, efana nohlobo lwe-bootloader.
