Zonse zidayamba pomwe [Damien Walsh] adapeza ma board a LED.Gulu lililonse lili ndi timatabwa tating'onoting'ono 100 ta LED tomwe titha kugawa ngati pakufunika.[Damien] anali ndi lingaliro labwinoko: zisungeni mugulu la 20 × 5 ndikupanga dalaivala kuti aziwongolera LED iliyonse pa WiFi.Anachita bwino (kanema wachidule wa post-hiatus adawonjezeredwa pansipa) ndipo adapereka upangiri wosangalatsa panjira yomanga kuyambira poyambira.
Vuto loyamba limene anakumana nalo ndi limene ambirife tingalingalire.Ndizovuta kufufuza chinachake pamene simukudziwa mawu olondola.Pankhani ya [Damien], kufufuza kwake kunamufikitsa kumalo osungiramo madalaivala a LED kuti aziwunikira mkati kapena kumbuyo.Zida zimenezi zimapanga ma LED ang'onoang'ono ambiri kukhala ngati gwero limodzi lalikulu la kuwala, koma amafuna kuti azigwira ntchito ndi aliyense payekha.
Pamapeto pake, adapunthwa pa ISSI's IS32FL3738 6 × 8 dot-matrix LED driver IC, yomwe ikugwirizana ndi biluyo.Atatu mwa iwo ndi okwanira kuyendetsa gulu la ma LED 100;imapereka chiwongolero cha I2C ndipo imatha kulunzanitsa PWM ya LED kudutsa tchipisi tambirimbiri kuti pasakhale kusuntha kosagwirizana pakati pa ma LED pa madalaivala osiyanasiyana.Tonse timakhala ndi zokonda zathu zikafika pa ma microcontrollers ndi kulumikizana kwa WiFi ndipo [Damien] ndiwokonda kwambiri mndandanda wa Espressif ESP32 ndipo akutsogolera ndi ESP32-WROOM.
Nkhani ina yofunika kuidziwa ndi waya.LED iliyonse imakhala pa PCB yake yaying'ono yokhala ndi mapepala owonekera, koma kugulitsa ma LED a 100 ndi ntchito yomwe ingapite kutali ndikukonzekera pang'ono.[Damien] anasankha makina oyambilira pogwiritsa ntchito mizere ya Kapton insulated copper tepi (chinthu chothandiza kwambiri chokhala ndi mbiri yomvetsa chisoni).ndi wosuta kwambiri kuposa kugulitsidwa ku waya.
Chophimba chosindikizidwa cha 3D chomwe chimagwiritsa ntchito pepala lolondera kuwunikira kuwala chimamaliza chipangizocho, ndikupanga matrix 20 x 5 a rectangles zoyendetsedwa payekhapayekha zomwe zimawala bwino komanso mofanana.Zotsatira zomaliza zikuwoneka zabwino kwambiri ndipo mutha kuziwona zikugwira ntchito muvidiyo yayifupi pansipa.
Ngati mukukumana ndi zofunikira zowongolera matrix a LED, onetsetsani kuti mwawerenga kalozera wowongolera matrix a LED komwe mungapeze malangizo othandiza.
"Pamapeto pake adapeza IS32FL3738 6x8 dot-matrix LED driver IC kuchokera ku ISSI [http://www.issi.com/US/index.shtml] ndipo ikugwirizana ndi biluyo," akutero Donald Papp.
IS32FL3738 imapangidwa ndi Lumissil, yomwe ndi gawo lodziyimira pawokha la ISSI [Integrated Silicon Solution Inc]. Lumissil adatchulidwa pa 20-March-2020 [1] ndipo poyamba ankadziwika kuti ISSI AMS [AMS> Analog and Mixed Signal division]. Lumissil adatchulidwa pa 20-March-2020 [1] ndipo poyamba ankadziwika kuti ISSI AMS [AMS> Analog and Mixed Signal division].Lumissil adatchulidwa pa Marichi 20, 2020.[1] ndi ранее был известен как ISSI AMS [AMS > подразделение аналоговых ndi смешанных сигналов]. [1] ndipo poyamba ankadziwika kuti ISSI AMS [AMS> Analogi ndi Mixed Signal Division]. Lumissil 于2020 年3 月20 日命名[1]，之前称為ISSI AMS [AMS > 模拟和混合信号部门]. Lumissil adatchedwa 于2020年3月20日[1], yemwe kale ankadziwika kuti ISSI AMS [AMS> kayeseleledwe ndi magawo osakanikirana azizindikiro].Lumissil adatchedwa [1] Marichi 20, 2020.ndi ранее был известен как ISSI AMS [AMS > Gawo la Analogi ndi Mixed Signal Division]. Poyamba ankadziwika kuti ISSI AMS [AMS> Analogi ndi Mixed Signal Division].
Patsambali, mukadina muvi wotsitsa wa IS32FL3738, mupeza zotsitsa zitatu: 1. IS32FL3738 data sheet, 2. IS32FL3738 evaluation board data sheet, ndi 3. Arduino code zitsanzo.Mukadina batani lotsitsa la "Sankhani Zonse" pawindo lowonekera, mudzalandira IS32FL3738.zip [1418 KB] yomwe ili ndi mafayilo atatu:
Malo osungira a IS32FL3738_AR.zip ali ndi fayilo imodzi: IS3xFL3738 EVB Arduino Code V01B.txt, yomwe imadzilankhula yokha.
