[Flipper Zero] ichidonhedza iyo Raspberry Pi uye kugadzira yedu bhodhi kubva kutanga. Kutsvaga iyo chaiyo WiFi chip

Zero pinball muchina - purojekiti yehomwe multitool yevanobira muTamagotchi fomu chinhu, chandiri kugadzira neshamwari. Previous post [1].

Zvakawanda zvakaitika kubva pakatanga kutumira nezve flipper. Tanga tichishanda nesimba nguva yese iyi uye chirongwa ichi chachinja zvakanyanya. Nhau huru ndeyekuti takasarudza kusiya zvachose Raspberry Pi Zero uye kugadzira bhodhi redu kubva pakatanga zvichibva pane i.MX6 chip. Izvi zvinoita kuti budiriro iwedzere kuoma uye inoshandura zvachose iyo pfungwa, asi ndine chokwadi kuti yakakosha.

Zvakare, isu hatisati tawana iyo chaiyo yeWiFi chipset inotsigira ese anodiwa mabasa ekurwiswa kweWiFi, tichitsigira bhendi re5Ghz uye kusiri makore gumi nemashanu kubva panguva. Naizvozvo, ndinokoka munhu wese kuti atore chikamu muongororo yedu.

Muchinyorwa ini ndichakuudza kuti sei takaita sarudzo iyi, ndeipi nhanho iyo purojekiti iri, mabasa azvino, uye maitiro aungaite.

Sei Raspberry Pi Zero yakaipa?

Ini pachangu ndinoda iyo Raspberry Pi, asi panguva yekuvandudza yakazove yekuyamwa nekuda kwezvikonzero zvakawanda. Chinhu chakanyanya banal ndechekuti iwe haugone kuitenga. Kunyangwe vagovanisi vakakura havana anopfuura mazana mashoma rpi0 zvidimbu mustock, uye zvitoro zvakaita seAdafruit neSparkfun zvinotengesa zvisingapfuure chidimbu chimwe paruoko. Ehe, kune akati wandei mafekitori anogadzira rpi1 pasi rezinesi kubva kuRaspberry Pi Foundation, asi ivo havakwanise kutumira mabheti ezviuru zvitatu-zvishanu. Zvinotaridza kunge rpi0 iri kutengeswa nemutengo uri padyo nemutengo uye wakanangwa zvakanyanya pakuparidzira chikuva.

Heano zvikonzero zvikuru zvekusiya rpi0

• Haikwanise kutengwa muhuwandu hwakawanda. Mafekitori akaita saFarnell anopa kutenga Compute Module. MaChinese anobva kuAlibaba anonyepa nezvekuvapo kwemavhoriyamu makuru, asi kana zvasvika kune batch chaiyo, vanobatana. Kune wese anonyora kuti isu hatina kutsvaga zvakanaka, edza kutaurirana nemumwe munhu kuti atenge zviuru zvishanu zvezvidimbu, kuitira kuti akutumire invoice yekubhadhara.
• Mainterface mashoma.
• Old BCM2835 processor, iyo yakashandiswa mune yekutanga vhezheni yerpi. Kupisa uye kusanyanya kushandisa simba.
• Iko hakuna manejimendi emagetsi, haugone kuisa bhodhi kurara.
• Yechinyakare yakavakirwa-mukati WiFi.
• nezvimwe zvikonzero zvakawanda.

Iyo Raspberry Pi Foundation pachayo inoratidza kushandisa iyo RPi Compute Module yemabasa akadaro. Iri ibhodhi muSO-DIMM module fomu factor (se RAM mumalaptops), iyo inoiswa mubhodhi reamai. Iyi sarudzo haina kukodzera isu, sezvo inowedzera zvakanyanya saizi yechigadzirwa.

Raspberry Pi Compute Module - bhodhi mune SO-DIMM module fomu chinhu chekuisa mumudziyo wako

Takabva tatanga kutarisa maSoM akasiyana (System on Module), mamodules akavakirwa pai.MX6 aitaridzika zvakanyanya. Zvese zvatinotsvaga zvinotsanangurwa mune shinda pane foramu Raspberry Pi Zero Alternatives. Asi iwe unofanirwa kuyeuka kuti haasi makambani ese achave akagadzirira kushanda newe pamavhoriyamu eiyo 3-5 zviuru zvimedu pagore. Semuenzaniso, veIsrael Variscite vakangomira kutipindura payakaona mavhoriyamu akarongwa ekutenga. Sezviri pachena, ivo havafarire kungotengesa maSoM pasina mamwe masevhisi nenzira yerutsigiro nekubatanidza. Ndinoda kunyanya kutaura nezveRussia developer Starterkit.ru, iyo inogadzira zvigadzirwa zvinonakidza, senge SK-iMX6ULL-NANO. Zvinenge zvisingaite kuGoogle, uye ndingadai ndisina kuziva nezvekuvapo kwavo dai shamwari dzangu dzisina kundiudza.

Nekuda kweizvozvo, mushure mekuenzanisa sarudzo dzese uye kufungidzira hupfumi, takaita danho rakaoma rekuita SoM yedu kubva kutanga yakanangana neFlipper zvichibva pane chip. i.MX6 ULZ. Iyo imwechete-musimboti Cortex-A7 inomhanya pa900 MHz ine ingangoita yakafanana neiyo rpi0, zvakadaro kunenge kutonhora pasi pemutoro, nepo rpi0 ichipisa sechitofu.
Nekugadzira bhodhi redu kubva kutanga, isu tine rusununguko rwakakwana mukurongeka kwezvinhu pabhodhi, ndosaka tichitarisira kuwana imwe compact mudziyo. i.MX6 ULZ ishanduro yakabviswa yei.MX6 ULL isina mamwe mainterfaces uye nheyo yevhidhiyo, saka pakuvandudza tinoshandisa MCIMX6ULL-EVK devboard ne i.MX6 ULL chip, pasina kushandisa mamwe maitiro. Iri bhodhi, nenzira, inotsigirwa neiyo mainline Linux kernel, saka Kali Linux ine kernel mapakeji inoiswa pairi.

Izvi ndizvo zvinoita flipper isina zvipfeko panguva ino:

WiFi chaiyo

WiFi yekubira ndechimwe chezvinhu zvikuru zveFlipper, saka zvakanyanya kukosha kusarudza iyo chaiyo WiFi chipset iyo inotsigira ese anodiwa mabasa: jekiseni repaketi uye yekutarisa maitiro. Panguva imwecheteyo, kwanisa kushandisa 5GHz renji uye zviyero zvemazuva ano se802.11ac. Zvinosuruvarisa, machipisi akadaro haana kuwanikwa pakarepo

Chinese SiP module (system in package) Apmak AP6255 yakavakirwa paBCM43456

Parizvino tiri kutarisa vanhu vakati wandei, asi vese vanoda kupedza uye hazvisati zvazivikanwa kuti ndeipi iri nani yekusarudza. Naizvozvo, ndinokumbira nemutsa wese munhu anonzwisisa WiFi poker kuti abatanidze kutsvaga kwedu pano: Wi-Fi chip ine SPI/SDIO interface inotsigira yekutarisa uye jekiseni repaketi

Vanonyanya kukwikwidza:

• Broadcom/Cypress BCM43455 kana BCM4345 ine zvigamba firmware. Hurukuro mu nexmon repository.
• Mediatek MT7668 - isati yaedzwa, asi muchirevo inogona kunge yakakodzera.

Ndapota, usati warayira chero chinhu, nyatsoverenga zvinodiwa paforamu, kusanganisira iyo yekubatanidza interface. Yeuka kuti ndanga ndichinyatsodzidza nyaya iyi kwemwedzi inoverengeka uye ndatochera zvose zvinogona kuwanikwa.

Chii chagadzirira

Iyo yese chikamu icho STM32 ine chekuita nayo chiri kutoshanda: 433Mhz, iButton, kuverenga-emulation 125kHz.
Iyo mechanic chikamu, mabhatani, kesi, zvibatanidza, dhizaini parizvino iri pasi pekusimudzira, muvhidhiyo uye mapikicha pazasi pekesi yechinyakare, mushanduro nyowani iyo joystick ichave yakakura.

Vhidhiyo inoratidza ratidziro yakapusa yekuvhura chipingamupinyi uchishandisa replay yeremote control chiratidzo.

FAQ

How to buy?

Sezvingabvira, tichaparura mushandirapamwe wekupa vanhu mari paKickstarter muna Kubvumbi-Chivabvu wegore rino. Isu tinotarisira kutumira zvishandiso zvakapedzwa mwedzi mitanhatu mushure mekupedzwa kwekuunganidza. Kana iwe uchifarira mudziyo, ndinokumbira kuti usiye email yako pazasi saiti, isu tichatumira zvinopihwa kune vanyoreri kana ma prototypes uye ekutanga samples agadzirira kutengeswa.

Zviri pamutemo here?

Ichi chishandiso chekutsvaga. Zvose zvayo zvinogona kutengwa zvakasiyana muchitoro. Kana iwe ukavaka adapta yeWiFi uye 433MHz transmitter mune diki kesi uye wowedzera skrini ipapo, haizove isiri pamutemo. Chigadzirwa chacho hachiwi pasi petsanangudzo yezvinokosha. nzira kana mudziyo wekuunganidza ruzivo muchivande. ZVIMWE chete hazvisi pamutemo kuishandisa nechinangwa chekukuvadza kana kuita zvisiri pamutemo. Mune mamwe mazwi, ndinogona kugadzira mapanga emhando ipi neipi uye kubva kune chero simbi, mutoro wekushandisa mapanga angu uri kwauri.

Kupa sei?

Parizvino unogona kunditsigira pachangu nezvipo zvidiki zvekudya kuburikidza Patreon. Mipiro yenguva dzose ye $ 1 iri nani kudarika yakawanda panguva nokuti inokubvumira kufanotaura mberi.

Ini ndinoburitsa zvese zvinyorwa papurojekiti mune yangu Telegraph chiteshi @zhovner_hub.
