Hoʻomaka ia i ka wā i loaʻa ai iā [Damien Walsh] kekahi mau papa LED kaʻawale. Loaʻa i kēlā me kēia papa he 100 mau papa kaapuni LED liʻiliʻi hiki ke wehe ʻia inā pono. He manaʻo maikaʻi aʻe ʻo [Damien]: e mālama iā lākou i loko o kahi ʻāpana 20 × 5 a hoʻomohala i kahi mea hoʻokele e hoʻokele i kēlā me kēia LED ma luna o WiFi. Ua kūleʻa ʻo ia (kahi wikiō demo post-hiatus pōkole i hoʻohui ʻia ma lalo) a hāʻawi i kekahi mau ʻōlelo aʻoaʻo hoihoi e pili ana i ke kaʻina hana mai ka ʻōpala.
ʻO ka pilikia mua i hiki iā ia ke noʻonoʻo i ka hapa nui o mākou. He mea paʻakikī ke noiʻi i kekahi mea inā ʻaʻole ʻoe ʻike i ka huaʻōlelo kūpono. Ma ka hihia o [Damien], ua alakaʻi ʻo ia iā ia i kahi cornucopia o nā mea hoʻokele LED no ka kukui o loko a i ʻole ke kukui hope. Ke hana nei kēia mau mea hana i nā LED liʻiliʻi he nui hoʻokahi kumu kukui nui, akā makemake ʻo ia e hiki ke hana pū me kēlā me kēia o lākou.
I ka hopena, ua hāʻule ʻo ia i ka ISSI IS32FL3738 6 × 8 dot-matrix LED driver IC, i kūpono i ka bila. ʻEkolu o lākou i lawa e hoʻokele i kahi panel o 100 LEDs; Hāʻawi ia i ka mana I2C a hiki iā ia ke hoʻohui pū i ka LED PWM ma waena o nā pahu he nui i ʻole ʻaʻohe flicker inconsistent ma waena o nā LED ma nā mea hoʻokele like ʻole. Loaʻa iā mākou nā mea punahele a pau i ka wā e pili ana i nā microcontrollers a me ka hoʻohui ʻana o WiFi a ʻo [Damien] kahi punahele nui o ka moʻo ESP32 ESP32 a ke alakaʻi nei i ke ala me ka ESP32-WROOM.
ʻO kahi pilikia ʻē aʻe e ʻike ʻia ʻo ia ka wiring. Noho kēlā me kēia LED ma kāna PCB liʻiliʻi me nā pads i hōʻike ʻia, akā ʻo ke kūʻai ʻana i nā LED 100 he hana hiki ke hele lōʻihi me kahi hoʻolālā liʻiliʻi. Ua koho ʻo [Damien] i kahi ʻōnaehana kumu me ka hoʻohana ʻana i nā ʻāpana o Kapton insulated copper tape (kahi mea hana lima me ka mōʻaukala pōʻino). ua ʻoi aku ka uahi ma mua o ke kūʻai ʻia ʻana i kahi uea.
Hoʻopiha ʻia ka mea hana ma kahi pahu paʻi paʻi 3D e hoʻohana ana i ka pepa ʻimi e hoʻopuehu i ka mālamalama, e hana ana i kahi matrix 20 x 5 o nā ʻāpana ʻāpana hoʻomalu pākahi e ʻālohilohi a me ka like. ʻIke maikaʻi ka hopena hopena a hiki iā ʻoe ke ʻike i ka hana ma ke wikiō pōkole ma lalo.
Inā ke alo nei ʻoe i kahi mana mana matrix LED like, e ʻoluʻolu e heluhelu i kēia alakaʻi alakaʻi alakaʻi LED matrix kahi e loaʻa ai iā ʻoe kekahi mau ʻōlelo kōkua.
"I ka hopena ua loaʻa iā ia kahi IS32FL3738 6×8 dot-matrix LED driver IC mai ISSI [http://www.issi.com/US/index.shtml] a kūpono ia i ka bila," wahi a Donald Papp.
Ua hana maoli ʻia ka IS32FL3738 e Lumissil, he māhele kūʻokoʻa o ISSI [Integrated Silicon Solution Inc]. Ua kapa ʻia ʻo Lumissil ma 20-Malaki-2020 [1] a ua ʻike mua ʻia ʻo ISSI AMS [AMS> Analog and Mixed Signal division].

Ma kēia ʻaoʻao, inā ʻoe e kaomi i ka pua download no IS32FL3738, e loaʻa iā ʻoe ʻekolu mau hoʻoiho: 1. IS32FL3738 pepa ʻikepili, 2. IS32FL3738 pepa loiloi papa helu helu, a me 3. Arduino code examples. Inā ʻoe e kaomi i ke pihi hoʻoiho "Select All" ma ka pukaaniani pop-up, e loaʻa iā ʻoe kahi waihona IS32FL3738.zip [1418 KB] me ʻekolu faila:
Aia ka waihona IS32FL3738_AR.zip i hoʻokahi faila: IS3xFL3738 EVB Arduino Code V01B.txt, e ʻōlelo ana nona iho.
Ma ka hoʻohana ʻana i kā mākou pūnaewele a me nā lawelawe, ua ʻae ʻoe i ka waiho ʻana o kā mākou hana, hana a me nā kuki hoʻolaha.
