Lingaliro la kulemba kachidindo popanda kulemba kachidindo (inde, kulemba ndi gawo laposachedwa la liwu loti kulemba, kukhala nalo tsopano) labwera m'maganizo mwa anthu anzeru komanso aulesi kangapo. Loto la mawonekedwe ojambulira momwe mutha kuponyera ena madayisi, jambulani maulalo olumikizana ndikusankha zinthu kuchokera pamndandanda wokongola wotsikira pansi, ndiyeno, pokanikiza batani lamatsenga "Pangani", pezani nambala yogwira ntchito yofanana ndi code. wa wina (osati wanzeru kwambiri, ndithudi) wokonza mapulogalamu pogwiritsa ntchito njira yachikale ya kulemba pamanja nthawi zonse amakhala wosungulumwa m'maganizo a mabwana onse amakampani omwe amalota kuti adziwitse wophunzira aliyense dzulo ku mapulogalamu, amene nzeru zake zinamulola kuti asaphonye chimbudzi, ndipo oyambitsa omwe akufuna kusangalatsa dziko lonse pamtengo wokwanira. Lero tikubweretsa kwa inu:
Ntchito ya Crowdfunding: Ezblock Pi.
Zofunika za polojekitiyi: Malo opangira mapulogalamu a Raspberry Pi motsatana ndi bolodi yokulitsa.
Platform: Woyambitsa.

Kuyesa kupanga mapangidwe apamwamba azithunzi pang'onopang'ono kunazimiririka; ngakhale mabwana apamwamba adazindikira kuti ndondomekoyi inali yovuta kwambiri kuti igwirizane ndi bedi la Procrustean la ma cubes amitundu yambiri. Mwamwayi, padakali ochita masewera ochita masewera omwe atsala, pankhani ya pulojekiti yobweretsera anthu ambiri - okonda Raspberry Pi. Pofuna kuti asalimbikitse mapulogalamu opanda kanthu, olembawo amawonjezera chilengedwe chachitukuko chojambula ndi bolodi yowonjezera, yomwe yapangidwa kuti ithandize njira yolumikizira zipangizo zakunja.
Patsamba la polojekiti, muvidiyo yamutu, tikudziwitsidwa kwa opanga mapulogalamu awiri a robotics, Robert ndi Emily. Robert, monga aliyense wodzilemekeza wovala taye ndi magalasi, amalemba mu Python njira yakale, pogwiritsa ntchito chowunikira ndi kiyibodi. Pankhani ya Amy, manja osamala a wina, akuwuluka m'mphepete mwa chimango, amachotsa kiyibodi, kuyang'anira komanso mbewa, m'malo mwake zonse ndi piritsi loyera loyera. Tabuletiyi, imagwiritsa ntchito pulogalamu yotchedwa Ezblock Studio, yomwe imakupatsani mwayi wolembera IoT yamakono mumayendedwe a Drag-n-Drop-n-be-happy.
Mwachilengedwe, pomwe Robert amalephera kuyesa pambuyo poyesa (mwina chifukwa chogwiritsa ntchito kiyibodi yamasewera), loboti Emily imathirira bwino chomeracho ndi madzi kuchokera pagalasi, mtsikanayo amalandira zidziwitso kuchokera ku loboti mwachindunji pafoni yake ndipo amamuwuza kuti ayankhe. pogwiritsa ntchito kuwongolera mawu.
Popeza mabwalowa akufunikabe kulumikizidwa ndi malingaliro amtundu wina, kumapeto kwa kanema, chithandizo cha zilankhulo zamapulogalamu chimalengezedwa, awa ndi Python ndi Swift (wodziwika bwino pavidiyoyi, piritsi, ali ndi apulo logo). Pokhapokha Amy akuyenera kudina pa kiyibodi yowonekera, popeza palibe amene wamubweza yokhazikika. Ezblock Studio imati imathandizira iOS, Android, Linux, Windows ndi macOS. Aliyense ali wokondwa. Chabwino, mwina kupatula Robert, yemwe adasowa pakati pa kanema; Mwina ankamwa mowa mwauchidakwa kapena anasiya.
Chabwino, ndikuganiza kuti ndizolemba zokwanira. Popanda chinyengo chilichonse, tiyeni tiwone zomwe opanga amatipatsa $35.
Pulojekiti ya Ezblock Pi pamasinthidwe ake ochepa imakhala ndi magawo atatu:
- bolodi la Ezblock Pi lokha, lomwe limagwiritsidwa ntchito ngati bolodi la Raspberry Pi;
- seti yofunikira ya ma module a 15 (palinso ma module a IoT, ogulitsidwa mumtengo wokwera mtengo wa $ 74, zambiri pansipa);
- kupeza Ezblock Studio, yomwe imakulolani kuti mulembe mapulogalamu a Raspberry Pi pogwiritsa ntchito zojambulajambula za Drag-n-Drop;
- pulasitiki yosonkhanitsa Raspberry Pi + Ezblock Pi;
- malangizo.
Ndi mlandu ndi malangizo, ndikuganiza kuti zonse zimveka bwino, tiyeni tione mwatsatanetsatane mfundo zitatu zoyambirira.
Zida za bolodi la Ezblock Pi zitha kuweruzidwa pongotchula "zothandizidwa ndi wolamulira wa STM32" komanso ndi chithunzi chosawoneka bwino cha prototype yoyamba. Zikuwoneka kuti bolodi ili ndi STM32 microcontroller mu phukusi la TQFP32. Microcontroller yotsika mtengo kwambiri mu phukusili, STM32L010K4T6 (ARM Cortex-M0+), imawononga β¬ 0,737 mu kuchuluka kwa zidutswa 100; okwera mtengo kwambiri, STM32F334K8T6 (ARM Cortex-M4) - β¬2.79 (mitengo ya Mouser). Mphamvu imaperekedwa ndi 3.3 V linear stabilizer mu phukusi la SOT-223, ndipo Bluetooth imaperekedwa ndi gawo lokonzekera, kuweruza ndi maonekedwe ake, monga ESP12E. Zolumikizira ziwiri za 20-pini ndi gawo la boardboard pakatikati pa bolodi ndizoyenera kulumikizana ndi dziko lakunja.
Kupangidwa kwa magawo oyambira a ma module a 15, kunena zoona, kunakhalabe chinsinsi kwa ine, ngakhale nditasanthula mwatsatanetsatane mafanizo a polojekitiyi. Ngati ma module athunthu a IoT ajambulidwa moona mtima ndikutchulidwa, ndiye kuti zoyambira zomwe zidaphatikizidwa mu phukusi loyambirira ndizobisika kuposa kapangidwe ka galimoto yatsopano chisanachitike chiwonetsero chachikulu chagalimoto. Zoyambira zimakulolani "kupanga ma projekiti 15 osiyanasiyana," koma m'mafanizo pali makatoni 10 omwe amawoneka kuti ali ndi zida zamagetsi mkati, koma zonse zomwe zidakhazikitsidwa sizimamveka.
Ponena za Studio ya Ezblock, ndidagawana kale kukayikira kwanga koyambirira kwa nkhani. M'malingaliro mwanga, dongosolo lomwe lingathe kuchita bwino zonse zomwe zatchulidwa (ndiloleni ndikukumbutseni: (block programming + Python + Swift) * (iOS + macOS + Android + Linux + Windows)) ikhoza kupangidwa bwino, koma ndikadapanga bajeti. pakupanga mapulogalamu otere pafupifupi ngati zaka 5 za munthu kapena chaka chimodzi cha ntchito kwa gulu la anthu asanu (mungapereke zingati?), Ngakhale mutagwiritsa ntchito mtundu wina wa multitool, monga Electron. Poganizira kuti omangawo adangotenga madola 10000 okha (ntchitoyi ikuwoneka yokondwa kwambiri, kotero tsopano 400% ya ndalamayi yasonkhanitsidwa kale), sizikudziwikiratu kuti gululi lidzadya chiyani panthawi yonse ya chitukuko. Ku mbiri ya olemba, tiyenera kuwonjezera kuti mtundu woyamba wa Ezblock Studio ulipo kale pa Google Play.
Zolemba zawonetserozi zili ndi typos zodziwika bwino kwa opanga aku China; pamenepa, injini yonjenjemera yomwe ili m'gulu la ma module a IoT imatchedwa "Vabration Module" m'malo mwa "Vibration Module". Komabe, nthawi ino opanga enieni sakuganiziranso za kubisala; Chonde, nazi chithunzi cha gulu cha okhala mtawuni ya Wilmington, Delaware:
Osandilakwitsa, sindikupepesa ngakhale pang'ono chifukwa cha malingaliro oyipa kwa opanga kuchokera ku PRC. Izi, mwachidziwikire, ndizogwirizana - choyamba, opanga mapulogalamu aku China adatenga gawo lalikulu la Google Play ndi Apple App Store masitolo, ndipo tsopano akupambana malo awo padzuwa mothandizidwa ndi nsanja za anthu ambiri. Crowdfunding ndi yabwino chifukwa imalola pafupifupi munthu aliyense wokhala ndi intaneti ndi khadi la banki kuti auze dziko lonse za chitukuko chake ndipo nthawi zina amapanga ndalama zabwino. Kusagwirizana kungayambitsidwe ndi kusinthasintha kwakukulu kwa kutsindika kuchokera ku luso la polojekiti kupita ku malonda a utawaleza, pamene zolakwika [zomwe zingatheke] zapangidwe zimatonthola, ndipo mbali yamaganizo ndi yachisangalalo imakokomeza kwambiri. Nachi chithunzi china kuchokera ku chiwonetsero cha Ezblock Pi:
Monga wolemba mavidiyo Evgeniy Bazhenov aka BadComedian akuti, "kusintha kwa wolemba" kwasungidwa. Kodi muli ndi malingaliro aliwonse amomwe, kukhala m'malingaliro abwino komanso kukumbukira bwino, kugwiritsa ntchito Raspberry Pi ndi "Vibration Module" kuti mupange IZI? Kapena kodi uku kukadali kuyitanira kwa gulu lathu losadziwa: "Tawonani momwe zimakhalira bwino, gulani mwachangu!"?
Kutenga kapena kusatenga? Choyamba, ndiloleni ndikukumbutseni kuti anthu a 509 apereka kale $ 41000 (ndi $ 10000 yofunsidwa), ndipo patsala pafupifupi masabata atatu kuti ntchitoyi ithe. Anthu amakonda. Mwina, ngati ndinu wokonda Raspberry Pi, mudzawonanso zabwino pamapangidwewo, kupitilira kusafuna kusiya ndi kuchuluka kwa $ 3 mpaka $ 35. Mwina nanunso, monga Robert wochokera muvidiyo yotsatsira, mwatopa ndi "kulemba mizere yobwerezabwereza." Kapena mwinamwake mumangoganiza kuti anyamata akuyenda m'njira yoyenera ndipo mukufuna kuwathandiza ndi jekeseni wanu wachuma. Ingokumbukirani kuti Rasipiberi Pi yokhayo imagulitsidwa pamtengo wofanana ndi $ 179 (sinditchula bwino mtengo wa Rasipiberi Pi Zero ndi Rasipiberi Pi Zero W pano), yomwe gulu la mainjiniya limayenera kulimbikira kuti lipange, ndipo yomwe imayendetsedwa ndi ARM Cortex-A35 yokhala ndi liwiro la wotchi ya 53 GHz, 1,4 Mbit Ethernet, Wi-Fi 1000n ndi Bluetooth 802.11.
Ndikuyendetsa yaing'ono , momwe ndinatengera nkhaniyi. Ngati muli ndi polojekiti yosangalatsa yopezera ndalama m'munda wa DIY kapena Open source hardware, gawani ulalowu ndipo tikambirananso. Kampeni za anthu ambiri ndizosakhalitsa ndipo zimalumikizidwa kwambiri ndi chithandizo cha anthu ammudzi, ndipo mwina kwa okonda m'modzi, ngakhale madongosolo ochepa ochokera kwa Habr athandizira kuti kampeniyi ithe.
