Nws tag nrho pib thaum [Damien Walsh] tau txais qee qhov seem LED boards.Txhua lub vaj huam sib luag muaj 100 lub teeb ci LED ci ntsa iab uas tuaj yeem muab sib cais yog tias xav tau.[Damien] muaj lub tswv yim zoo dua: khaws cia rau hauv 20 × 5 array thiab txhim kho tus tsav tsheb los tswj txhua qhov LED hla WiFi.Nws tau ua tiav (qhov luv luv post-hiatus demo video ntxiv hauv qab no) thiab muab qee cov lus qhia nthuav dav ntawm cov txheej txheem ntawm kev tsim los ntawm kos.
Thawj qhov teeb meem uas nws ntsib yog ib qho uas peb feem coob xav txog.Nws yog ib qho nyuaj rau kev tshawb fawb ib yam dab tsi thaum koj tsis paub cov lus zoo.Hauv [Damien's] cov ntaub ntawv, nws txoj kev tshawb nrhiav coj nws mus rau cornucopia ntawm LED tsav tsheb rau sab hauv teeb pom kev zoo lossis backlighting.Cov khoom siv no ua rau ntau lub LEDs me me ua ib lub teeb ci loj, tab sis nws xav ua haujlwm nrog txhua tus ntawm lawv tus kheej.
Thaum kawg, nws ntog rau ISSI's IS32FL3738 6 × 8 dot-matrix LED tsav IC, uas haum rau daim nqi.Peb ntawm lawv txaus los tsav lub vaj huam sib luag ntawm 100 LEDs;nws muaj I2C tswj thiab tseem muaj peev xwm synchronize LED PWM hla ntau lub chips kom tsis muaj qhov tsis sib xws ntawm cov LEDs ntawm cov tsav tsheb sib txawv.Peb txhua tus muaj peb txoj kev nyiam thaum nws los txog rau microcontrollers thiab WiFi kev sib txuas thiab [Damien] yog tus kiv cua loj ntawm Espressif ESP32 series thiab tab tom ua txoj hauv kev nrog ESP32-WROOM.
Lwm qhov teeb meem yuav tsum paub txog yog kev xaim.Txhua LED zaum ntawm nws tus kheej PCB me me nrog cov ntaub qhwv tau yooj yim, tab sis soldering 100 LEDs yog ib txoj haujlwm uas tuaj yeem mus ntev nrog kev npaj me ntsis.[Damien] xaiv rau ib qho tseem ceeb uas siv cov strips ntawm Kapton insulated tooj liab daim kab xev (ib qho khoom siv tau zoo heev nrog keeb kwm tragic).nws yog smoky ntau tshaj li raug soldered rau ib tug hlau.
Lub 3D luam ntawv baffle uas siv daim ntawv tracing rau diffuse lub teeb ua tiav cov cuab yeej, tsim kom muaj 20 x 5 matrix ntawm tus kheej tswj cov duab plaub uas ci ntsa iab thiab sib npaug.Qhov kawg tshwm sim zoo li zoo heev thiab koj tuaj yeem pom nws ua haujlwm hauv cov yeeb yaj kiab luv luv hauv qab no.
Yog tias koj tab tom ntsib qhov zoo sib xws LED matrix tswj xav tau, nco ntsoov nyeem phau ntawv qhia LED matrix tswj qhov chaw koj yuav pom qee cov lus qhia muaj txiaj ntsig.
"Thaum nws pom IS32FL3738 6 × 8 dot-matrix LED tsav tsheb IC los ntawm ISSI [http://www.issi.com/US/index.shtml] thiab nws haum rau daim nqi," said Donald Papp.
Lub IS32FL3738 yog tiag tiag tsim los ntawm Lumissil, uas yog ib tug ywj siab faib ntawm ISSI [Integrated Silicon Solution Inc]. Lumissil tau muaj npe nyob rau 20-Lub Peb Hlis-2020 [1] thiab yav dhau los hu ua ISSI AMS [AMS> Analog thiab Mixed Signal division]. Lumissil tau muaj npe nyob rau 20-Lub Peb Hlis-2020 [1] thiab yav dhau los hu ua ISSI AMS [AMS> Analog thiab Mixed Signal division].Lumissil tau muaj npe nyob rau lub Peb Hlis 20, 2020.[1] thiab ранее был известен как ISSI AMS [AMS > подразделение аналоговых и смешанных сигналов]. [1] thiab yav tas los hu ua ISSI AMS [AMS> Analog thiab Mixed Signal Division]. Lumissil Lub Ob Hlis 2020 Lub Ob Hlis 3, 2020 日命名[1]，之前称为ISSI AMS [AMS > 模拟和混合信号部门]. Lumissil tau hu ua 于2020年3月20日[1], yav tas los hu ua ISSI AMS [AMS > simulation thiab sib xyaw teeb liab sib faib].Lumissil tau muaj npe [1] Lub Peb Hlis 20, 2020.thiab ранее был известен как ISSI AMS [AMS > Analog thiab Mixed Signal Division]. Nws yog yav tas los hu ua ISSI AMS [AMS > Analog thiab Mixed Signal Division].
