Konke kwaqala ngenkathi [uDamien Walsh] ethola amabhodi e-LED ayisipele.Iphaneli ngayinye iqukethe amabhodi esekethe e-LED akhanyayo angama-100 angahlukaniswa uma kudingeka.[UDamien] ube nombono ongcono: uwagcine ohlwini lwama-20×5 futhi uthuthukise umshayeli ukuze alawule i-LED ngayinye nge-WiFi.Uphumelele (ividiyo yedemo emfushane ye-post-hiatus yengezwe ngezansi) futhi wanikeza izeluleko ezithakazelisayo ngenqubo yokwakha kusukela ekuqaleni.
Ingqinamba yokuqala abhekana nayo ingelinye iningi lethu elingacabanga ngalo.Kunzima ukucwaninga okuthile uma ungawazi amagama afanele.Esimeni [sikaDamien], ukusesha kwakhe kumholele endaweni eyi-cornucopia yama-LED driver ukuze akhanyiselwe ngaphakathi noma akhanyiselwe emuva.Lawa madivayisi enza ama-LED amaningi amancane asebenze njengomthombo owodwa omkhulu wokukhanya, kodwa ufuna ukwazi ukusebenza nawo ngamunye ngamunye.
Ekugcineni, wazithela ku-ISSI's IS32FL3738 6x8 dot-matrix LED driver IC, elingana nomthethosivivinywa.Ezintathu zazo zanele ukushayela iphaneli ye-100 LEDs;inikeza ukulawula kwe-I2C futhi ikwazi ngisho nokuvumelanisa i-LED PWM kuwo wonke ama-chips amaningi ukuze kungabikho ukucwayiza okungahambisani phakathi kwama-LED kumashayeli ahlukene.Sonke sinezintandokazi zethu uma kuziwa kuma-microcontroller kanye noxhumo lwe-WiFi futhi [uDamien] ungumlandeli omkhulu wochungechunge lwe-Espressif ESP32 futhi uhamba phambili nge-ESP32-WROOM.
Enye inkinga okufanele uyiqaphele i-wiring.I-LED ngayinye ihlala ku-PCB yayo encane enamaphedi atholakala kalula, kodwa ukuhlanganisa ama-LED angu-100 kuwumsebenzi ongahamba ibanga elide ngokuhlela okuncane.[UDamien] ukhethe isistimu yoqobo esebenzisa imicu ye-Kapton insulated copper tape (into ewusizo kakhulu enomlando odabukisayo).ishunqa kakhulu kunokudayiswa ocingweni.
I-baffle ephrintiwe ye-3D esebenzisa iphepha lokulandelela ukusabalalisa ukukhanya iqeda idivayisi, idala i-matrix engu-20 x 5 yonxande abalawulwa ngabanye abakhanya ngokushelela nangokulinganayo.Umphumela ubukeka umuhle futhi ungawubona usebenza kuvidiyo emfushane engezansi.
Uma ubhekene nesidingo esifanayo sokulawula imatrix ye-LED, qiniseka ukuthi ufunda lo mhlahlandlela wokulawula matrix we-LED lapho uzothola khona amathiphu awusizo.
"Ekugcineni wathola i-IS32FL3738 6×8 dot-matrix LED driver IC evela ku-ISSI [http://www.issi.com/US/index.shtml] futhi yayilingana nomthethosivivinywa," kusho uDonald Papp.
I-IS32FL3738 empeleni yakhiwe ngabakwaLumissil, okuyingxenye ezimele ye-ISSI [Integrated Silicon Solution Inc]. I-Lumissil yaqanjwa ngo-20-March-2020 [1] futhi ngaphambili yaziwa ngokuthi yi-ISSI AMS [AMS > Analog and Mixed Signal division]. I-Lumissil yaqanjwa ngo-20-March-2020 [1] futhi ngaphambili yaziwa ngokuthi yi-ISSI AMS [AMS > Analog and Mixed Signal division].I-Lumissil yaqanjwa ngoMashi 20, 2020.[1] futhi ранее был известен как ISSI AMS [AMS > подразделение аналоговых и смешанных сигналов]. [1] futhi phambilini bekwaziwa ngokuthi yi-ISSI AMS [AMS > I-Analog ne-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]. I-Lumissil yaqanjwa ngokuthi 于2020年3月20日[1], ngaphambili eyaziwa ngokuthi i-ISSI AMS [AMS > ukulingisa nokuhlukaniswa kwesignali exubile].I-Lumissil yaqanjwa [1] ngoMashi 20, 2020.и ранее был известен как ISSI AMS [AMS > I-Analogi Nesiginali Ehlanganisiwe]. Ngaphambilini yayaziwa ngokuthi yi-ISSI AMS [AMS > I-Analog kanye ne-Mixed Signal Division].
Kuleli khasi, uma uchofoza umcibisholo wokulanda we-IS32FL3738, uzothola ukulanda okuthathu: 1. IS32FL3738 ishidi ledatha, 2. IS32FL3738 ishidi ledatha yebhodi lokuhlola, kanye nezibonelo 3. zekhodi ye-Arduino.Uma uchofoza inkinobho yokukhipha ethi “Khetha Konke” efasiteleni le-pop-up, uzothola ingobo yomlando ye-IS32FL3738.zip [1418 KB] equkethe amafayela amathathu:
Ingobo yomlando ye-IS32FL3738_AR.zip iqukethe ifayela elilodwa: IS3xFL3738 EVB Arduino Code V01B.txt, elizikhulumelayo.
