![[Flipper Zero] akugwetsa Raspberry Pi ndikupanga gulu lathu kuyambira poyambira. Kupeza chipangizo cha WiFi choyenera](https://prohoster.info/wp-content/plugins/wp-fastest-cache-premium/pro/images/blank.gif)
- pulojekiti ya thumba la multitool kwa obera mu Tamagotchi form factor, yomwe ndikupanga ndi anzanga. Nkhani yam'mbuyo .
Zambiri zachitika kuyambira pomwe positi yoyamba yokhudzana ndi flipper. Takhala tikugwira ntchito molimbika nthawi yonseyi ndipo ntchitoyi yasintha kwambiri. Nkhani yaikulu ndiyakuti tinaganiza zosiya Raspberry Pi Zero kwathunthu ndikupanga bolodi lathu kuchokera pachiwonetsero kutengera chipangizo cha i.MX6. Izi zimapangitsa chitukuko kukhala chovuta kwambiri ndikusintha lingaliro lonse, koma ndikutsimikiza kuti ndizofunika.
Komanso, sitinapezebe chipangizo cha WiFi cholondola chomwe chimathandizira ntchito zonse zofunika pakuwukira kwa WiFi, pomwe timathandizira gulu la 5Ghz komanso kusakhala ndi zaka 15. Chifukwa chake, ndikupempha aliyense kutenga nawo mbali pazofufuza zathu.
M'nkhaniyi ndikuwuzani chifukwa chomwe tidapangira izi, momwe polojekitiyi ilili, ntchito zomwe zikuchitika, komanso momwe mungatengere nawo gawo.
Chifukwa chiyani Raspberry Pi Zero ndi yoyipa?
Ineyo pandekha ndimakonda Raspberry Pi, koma panthawi yachitukuko zidayamba kuyamwa pazifukwa zambiri. Choyipa kwambiri ndichakuti simungagule. Ngakhale ogulitsa akuluakulu alibe ndalama zokwana ma rpi0 mazana angapo, ndipo masitolo monga Adafruit ndi Sparkfun sagulitsa chidutswa chimodzi pamanja. Inde, pali mafakitale angapo omwe amapanga rpi1 pansi pa chilolezo kuchokera ku Raspberry Pi Foundation, koma sangathenso kutumiza magulu a zidutswa 0-3 zikwi. Zikuwoneka kuti rpi5 ikugulitsidwa pamtengo womwe uli pafupi ndi mtengo ndipo cholinga chake ndi kulengeza nsanja.
Nazi zifukwa zazikulu zosiyira rpi0
- Sizingagulidwe mochuluka. Mafakitole ngati Farnell amapereka kugula Compute Module. Anthu aku China ochokera ku Alibaba amanama za kupezeka kwa mabuku akuluakulu, koma zikafika pagulu lenileni, amaphatikizana. Kwa aliyense amene amalemba kuti sitinafufuze bwino, yesetsani kukambirana ndi munthu kuti mugule zidutswa za 5, kuti akutumizireni invoice yolipira.
- Malo ochezera ochepa.
- Purosesa yakale ya BCM2835, yomwe idagwiritsidwa ntchito mu mtundu woyamba wa rpi. Zotentha komanso zosagwiritsa ntchito mphamvu zambiri.
- Palibe kasamalidwe ka mphamvu, simungathe kugona gululo.
- WiFi yomangidwa kale.
- ndi zifukwa zina zambiri.
Raspberry Pi Foundation yokha ikuwonetsa kugwiritsa ntchito RPi Compute Module pazinthu zotere. Ili ndi bolodi mu SO-DIMM module form factor (monga RAM mu laputopu), yomwe imayikidwa mu boardboard. Njirayi si yoyenera kwa ife, chifukwa imawonjezera kukula kwa chipangizocho.
Raspberry Pi Compute Module - bolodi mu SO-DIMM module form factor kuti muyike pa chipangizo chanu
Kenako tinayamba kuyang'ana ma SoM osiyanasiyana (System on Module), ma modules ozikidwa pa i.MX6 ankawoneka okongola kwambiri. Zosaka zathu zonse zikufotokozedwa mu ulusi pa forum. Koma muyenera kukumbukira kuti si makampani onse adzakhala okonzeka kugwira ntchito ndi inu mu mabuku ngakhale 3-5 zikwi zidutswa pachaka. Mwachitsanzo, a Variscite a ku Israeli anangosiya kutiyankha atapeza mabuku ogula omwe akukonzekera. Mwachiwonekere, alibe chidwi chongogulitsa ma SoM opanda mautumiki owonjezera mwa njira yothandizira ndi kuphatikiza. Ndikufuna makamaka kutchula woyambitsa Russian , zomwe zimapanga zida zosangalatsa kwambiri, monga . Ndizosatheka kwa Google, ndipo sindikadadziwa za kukhalapo kwawo anzanga akadapanda kundiuza.
Zotsatira zake, titatha kufananiza zosankha zonse ndikuyerekeza zachuma, tidapanga chisankho chovuta kupanga SoM yathu kuyambira pachiyambi makamaka kwa Flipper yotengera chip. . Ndi imodzi-core Cortex-A7 yomwe ikuyenda pa 900 MHz yomwe imakhala yofanana ndi rpi0, komabe imakhala yozizira kwambiri, pamene rpi0 ndiyotentha ngati chitofu.
Popanga bolodi lathu kuyambira pachiyambi, timakhala ndi ufulu wathunthu pamakonzedwe a zinthu pa bolodi, chifukwa chake tikuyembekeza kupeza chipangizo chophatikizika. i.MX6 ULZ ndi mtundu wovumbulutsidwa wa i.MX6 ULL wopanda mawonekedwe ena ndi chigawo cha kanema, kotero kuti chitukuko tigwiritse ntchito MCIMX6ULL-EVK devboard ndi chip i.MX6 ULL, popanda kugwiritsa ntchito zina. Board iyi, mwa njira, imathandizidwa ndi kernel yayikulu ya Linux, kotero Kali Linux yokhala ndi mapaketi a kernel imakwezedwa pamenepo.
Izi ndi zomwe flipper imawoneka popanda zovala pakadali pano:
WiFi yolondola
Kubera kwa WiFi ndi chimodzi mwazinthu zazikulu za Flipper, chifukwa chake ndikofunikira kwambiri kusankha chipangizo choyenera cha WiFi chomwe chimathandizira ntchito zonse zofunika: jakisoni wa paketi ndikuwunika. Nthawi yomweyo, mutha kugwiritsa ntchito mtundu wa 5GHz ndi miyezo yamakono ngati 802.11ac. Tsoka ilo, tchipisi zotere sizinapezeke nthawi yomweyo
Chinese SiP module (dongosolo mu phukusi) Apmak AP6255 zochokera BCM43456
Pakali pano tikuganiza za ofuna kusankhidwa angapo, koma onse amafuna kumaliza ndipo sizikudziwika kuti ndi ndani amene ali bwino kusankha. Chifukwa chake, ndikupempha aliyense amene amamvetsetsa poker ya WiFi kuti alowe nawo pakusaka kwathu pano:
Ofuna kutsata:
- Broadcom/Cypress BCM43455 kapena BCM4345 yokhala ndi zigamba.
- Mediatek MT7668 - sinayesedwe, koma m'malingaliro ikhoza kukhala yoyenera.
Chonde, musanayambe kulangiza chilichonse, werengani mosamala zofunikira pa forum, kuphatikizapo mawonekedwe ogwirizanitsa. Kumbukirani kuti ndakhala ndikuwerenga nkhaniyi mosamalitsa kwa miyezi ingapo ndipo ndafufuza kale zonse zomwe zingapezeke.
Zomwe zakonzeka
Gawo lonse lomwe STM32 imayang'anira likugwira ntchito kale: 433Mhz, iButton, kuwerenga-emulation 125kHz.
Gawo lamakina, mabatani, kesi, zolumikizira, masanjidwewo pakali pano akukula mwachangu, mu kanema ndi zithunzi zomwe zili pansipa pakanthawi kochepa, m'mitundu yatsopano yosangalatsa idzakhala yayikulu.
Kanemayo akuwonetsa chiwonetsero chosavuta chotsegula chotchinga pogwiritsa ntchito kubwereza kwa chizindikiro chakutali.
FAQ
Kodi mungagule bwanji?
Mwina, tidzayambitsa kampeni yopezera anthu ambiri pa Kickstarter mu Epulo-Meyi chaka chino. Tikuyembekeza kutumiza zida zomalizidwa miyezi isanu ndi umodzi pambuyo pomaliza kusonkhanitsa. Ngati mumakonda chipangizochi, ndikukupemphani kuti musiye imelo yanu pansipa , tidzatumiza zopereka kwa olembetsa pamene ma prototypes ndi zitsanzo zoyambirira zakonzeka kugulitsidwa.
Ndizovomerezeka?
Ichi ndi chida chofufuzira. Zigawo zake zonse zitha kugulidwa padera m'sitolo. Ngati mupanga adaputala ya WiFi ndi 433MHz transmitter mu kanyumba kakang'ono ndikuwonjezera chophimba pamenepo, sizikhalanso zoletsedwa. Chipangizocho sichimagwera pansi pa tanthauzo lapadera. njira kapena chipangizo chopezera zambiri mwachinsinsi. Ndi zoletsedwa kuzigwiritsa ntchito ndicholinga chowononga kapena kuchita zinthu zosemphana ndi malamulo. Mwa kuyankhula kwina, ndikhoza kupanga mipeni ya mawonekedwe aliwonse komanso kuchokera kuchitsulo chilichonse, udindo wogwiritsa ntchito mipeni yanga uli ndi inu.
Kodi mungapereke bwanji?
Pakadali pano mutha kundithandiza ndekha ndi zopereka zazing'ono za chakudya kudzera . Zopereka zokhazikika za $ 1 ndizabwinoko kuposa kuchuluka kwakukulu panthawi imodzi chifukwa zimakulolani kulosera zam'tsogolo.
Ndimasindikiza zolemba zonse za polojekitiyi mu njira yanga ya Telegraph .
