🥇[Flipper Zero] Shiya iRaspberry Pi kwaye wenze eyakho ibhodi ukusuka ekuqaleni. Ukufumana iChip eLungileyo yeWiFi

I-Pinball Zero -Iprojekthi yepokotho ye-multitool yabaduni kwifom ye-Tamagotchi, endiyiphuhlisayo nabahlobo. Isithuba sangaphambili [1].

Kuninzi okwenzekileyo ukususela kwisithuba sokuqala malunga ne-flipper. Besisebenza nzima lonke eli xesha kwaye iprojekthi iye yatshintsha kakhulu. Iindaba eziphambili kukuba sagqiba ekubeni silahle ngokupheleleyo i-Raspberry Pi Zero kwaye senze ibhodi yethu ukusuka ekuqaleni ngokusekelwe kwi-chip ye-i.MX6. Oku kwenza uphuhliso lubenzima kakhulu kwaye lutshintshe ngokupheleleyo ingqikelelo, kodwa ndiqinisekile ukuba kufanelekile.

Kwakhona, asikafumani i-chipset ye-WiFi efanelekileyo exhasa yonke imisebenzi eyimfuneko yokuhlaselwa kwe-WiFi, ngelixa ixhasa ibhendi ye-5Ghz kwaye ingekho iminyaka eyi-15 ngaphandle kwexesha. Ke ngoko, ndimema wonke umntu ukuba athathe inxaxheba kuphando lwethu.

Kwinqaku ndiza kukuxelela ukuba kutheni senze esi sigqibo, yeyiphi inqanaba le projekthi, imisebenzi yangoku, kunye nendlela onokubandakanyeka ngayo.

Kutheni iRaspberry Pi Zero imbi?

Mna ngokwam ndiyayithanda iRaspberry Pi, kodwa ngexesha lenkqubo yophuhliso yajika yancanca ngenxa yezizathu ezininzi. Eyona nto inqabileyo kukuba awukwazi ukuyithenga. Nabasasazi abakhulu abanayo ngaphezulu kwamakhulu amabini amaqhekeza e-rpi0 kwisitokhwe, kwaye iivenkile ezinjenge-Adafruit kunye ne-Sparkfun azithengisi ngaphezulu kweqhekeza elinye ngesandla. Ewe, kukho iifektri ezininzi ezivelisa i-rpi1 phantsi kwelayisensi evela kwi-Raspberry Pi Foundation, kodwa nazo azikwazi ukuthumela iibhetshi zamaqhekeza angama-0-3 amawaka. Kubonakala ngathi i-rpi5 ithengiswa ngexabiso elikufutshane neendleko kwaye ijolise ngakumbi ekuvakaliseni iqonga.

Nazi izizathu eziphambili zokushiya i-rpi0

Ayinakuthengwa ngobuninzi. Iifektri ezifana noFarnell zibonelela ngokuthenga iModyuli yeKhompyutha. AmaShayina avela e-Alibaba amanga malunga nobukho bemiqulu emikhulu, kodwa xa kuziwa kwi-batch yangempela, badibanisa. Kuwo wonke umntu obhala ukuba asikhange sikhangele kakuhle, zama ukuxoxisana nomntu ukuba athenge amaqhekeza angama-5 amawaka, ukuze akuthumelele i-invoyisi yokuhlawula.
Ujongano olumbalwa.
Iprosesa endala ye-BCM2835, eyayisetyenziswa kwinguqulelo yokuqala ye-rpi. Kushushu kwaye akuwongi kakhulu amandla.
Akukho lawulo lwamandla, awukwazi ukuyilalisa ibhodi.
I-WiFi eyakhelwe-ngaphakathi ephelelwe lixesha.
kunye nezinye izizathu ezininzi.

I-Raspberry Pi Foundation ngokwayo icebisa ukusebenzisa i-RPi Compute Module kwimisebenzi enjalo. Le yibhodi kwimodyuli ye-SO-DIMM yefom factor (njenge-RAM kwiilaptops), efakwe kwi-motherboard. Olu khetho alufanelekanga kuthi, njengoko lunyusa kakhulu ubungakanani besixhobo.

Imodyuli yeRaspberry Pi yeKhompyutha-ibhodi kwimodyuli ye-SO-DIMM yefom yofakelo kwisixhobo sakho

Emva koko saqala ukujonga kwii-SoM ezahlukeneyo (iSystem kwiModyuli), iimodyuli ezisekelwe kwi-i.MX6 zikhangeleke kakhulu. Lonke uphendlo lwethu luchazwe kumsonto kwiforum Raspberry Pi Zero Alternatives. Kodwa kufuneka ukhumbule ukuba ayizizo zonke iinkampani eziya kuba zilungele ukusebenza nawe kwimiqulu engamawaka angama-3-5 ngonyaka. Ngokomzekelo, i-Variscite yakwa-Israeli yavele yayeka ukusiphendula xa ifumanisa imiqulu yokuthenga ecwangcisiweyo. Kubonakala ukuba, abanamdla ekuthengiseni nje ii-SoM ngaphandle kweenkonzo ezongezelelweyo ngendlela yenkxaso kunye nokudibanisa. Ndingathanda ngokukodwa ukukhankanya umphuhlisi waseRashiya Starterkit.ru, ezenza izixhobo ezinomdla kakhulu, njenge SK-iMX6ULL-NANO. Phantse zingenakwenzeka kuGoogle, kwaye ngendingazi ngobukho bazo ukuba abahlobo bam bebengandixelelanga.

Ngenxa yoko, emva kokuthelekisa zonke iinketho kunye nokuqikelela uqoqosho, senze isigqibo esinzima sokwenza i-SoM yethu ukusuka ekuqaleni ngokukodwa kwi-Flipper esekelwe kwi-chip. i.MX6 ULZ. YiCortex-A7 ene-single-core esebenza kwi-900 MHz ephantse isebenze ngokufanayo ne-rpi0, kodwa iphantse yabanda phantsi komthwalo, ngelixa i-rpi0 ishushu njengesitovu.
Ngokwenza ibhodi yethu ukusuka ekuqaleni, sinenkululeko epheleleyo kulungiselelo lwezinto ebhodini, yingakho silindele ukufumana isixhobo esincinci ngakumbi. I-i.MX6 ULZ yinguqulo ehluthiweyo ye-i.MX6 ULL ngaphandle kwe-interfaces ethile kunye nevidiyo engundoqo, ngoko ke uphuhliso sisebenzisa i-devboard ye-MCIMX6ULL-EVK kunye ne-chip ye-i.MX6 ULL, ngaphandle kokusebenzisa ezinye ze-interfaces. Le bhodi, ngendlela, ixhaswa yi-Linux kernel engundoqo, ngoko iKali Linux eneepakethe zekernel ilayishwe kuyo.

Le yindlela i-flipper ekhangeleka ngayo ngaphandle kwempahla okwangoku:

I-WiFi echanekileyo

Ukukhwabanisa kwe-WiFi yenye yezona zinto ziphambili zeFlipper, ngoko kubaluleke kakhulu ukukhetha i-chipset ye-WiFi efanelekileyo eya kuxhasa yonke imisebenzi eyimfuneko: inaliti yepakethe kunye nemowudi yokubeka iliso. Kwangaxeshanye, ukwazi ukusebenzisa uluhlu lwe-5GHz kunye nemigangatho yanamhlanje efana ne-802.11ac. Ngelishwa, iitshiphusi ezinjalo azizange zifumaneke kwangoko

Imodyuli yeSiP yesiTshayina (inkqubo kwiphakheji) Apmak AP6255 esekelwe kwi-BCM43456

Ngoku siqwalasela abagqatswa abaliqela, kodwa bonke bafuna ukugqitywa kwaye akukaziwa ukuba ngowuphi ongcono onokukhetha. Ke ngoko, ndicela wonke umntu oyiqondayo iWiFi poker ukuba ajoyine uphendlo lwethu apha: I-chip ye-Wi-Fi ene-SPI/SDIO ujongano oluxhasa ukubekwa esweni kunye nenaliti yepakethe

Abagqatswa abaphambili:

I-Broadcom/Cypress BCM43455 okanye i-BCM4345 ene-firmware echweliweyo. Ingxoxo kwindawo yokugcina i-nexmon.
I-Mediatek MT7668 - ayikavavanywa, kodwa kwithiyori inokufaneleka.

Nceda, ngaphambi kokuba ucebise nantoni na, funda ngokucophelela iimfuno kwiforum, kubandakanywa ujongano loqhagamshelwano. Khumbula ukuba bendifunda ngokucokisekileyo esi sihloko kangangeenyanga ezininzi kwaye sele ndimbe yonke into enokufumaneka.

Yintoni elungile

Inxalenye yonke apho i-STM32 inoxanduva sele isebenza: 433Mhz, iButton, ukufunda-emulation 125kHz.
Inxalenye yomatshini, amaqhosha, imeko, izihlanganisi, ubeko ngoku ziphantsi kophuhliso olusebenzayo, kwividiyo kunye neefoto ezingezantsi kwimeko yakudala, kwiinguqulelo ezintsha i-joystick iya kuba nkulu.

Ividiyo ibonisa umboniso olula wokuvula umqobo usebenzisa i-replay yesiginali yokulawula kude.

FAQ

Indlela yokuthenga?

Kucingelwa ukuba, siza kuphehlelela iphulo lokuxhasa abantu abaninzi kwi-Kickstarter ngo-Epreli-Meyi walo nyaka. Sinethemba lokuthumela izixhobo ezigqityiweyo kwiinyanga ezintandathu emva kokugqitywa kokuqokelela. Ukuba unomdla kwisixhobo, ndikucela ukuba ushiye i-imeyile yakho ngezantsi indawo, siya kuthumela izibonelelo kubabhalisi xa iiprototypes kunye neesampuli zangaphambili zilungele ukuthengiswa.

Isemthethweni?

Esi sisixhobo sophando. Zonke iinxalenye zayo zingathengwa ngokwahlukileyo kwivenkile. Ukuba wakha iadaptha ye-WiFi kunye ne-433MHz yokuhambisa kwityala elincinci kwaye wongeze isikrini apho, ayisayi kuba yinto engekho mthethweni. Isixhobo asiwi phantsi kwenkcazo ekhethekileyo. indlela okanye isixhobo sokuqokelela ngokufihlakeleyo ulwazi. AKUKHO mthethweni KUPHELA ukuyisebenzisela injongo yokudala umonakalo okanye imisebenzi engekho mthethweni. Ngamanye amazwi, ndingenza iimela zayo nayiphi na imilo kwaye nakweyiphi na isinyithi, uxanduva lokusebenzisa iimela zam likuwe.

Unikela njani?

Okwangoku ungandixhasa buqu ngeminikelo yokutya encinci nge Preon. Iminikelo eqhelekileyo ye-1 yeedola ingcono kakhulu kunemali eninzi ngexesha kuba ikuvumela ukuba uqikelele kwangaphambili.
