I timata katoa i te wa i whiwhi ai a [Damien Walsh] etahi papa LED e manawapa ana.He 100 nga papa taiawhio arai arai LED ka taea te wehe mena ka hiahiatia.He pai ake te whakaaro a [Damien]: penapenahia ki roto i te raupapa 20×5 ka hangaia he taraiwa hei whakahaere i ia LED ma runga WiFi.I angitu ia (he ataata whakaata poto i muri i te hiatus kua taapirihia ki raro) me etahi tohutohu pai mo te mahi hanga whare mai i te wahanga.
Ko te raru tuatahi i pa ki a ia ko tetahi e taea e te nuinga o tatou te whakaaro.He uaua ki te rangahau i tetahi mea kaore koe e mohio ki nga kupu tika.I roto i te keehi a [Damien], na tana rapunga i arahi ia ki te tini o nga kaitaraiwa LED mo te rama o roto, mo te rama whakamuri ranei.Ko enei taputapu he maha nga rama iti e mahi ana hei puna marama nui, engari e hiahia ana ia kia kaha ki te mahi takitahi.
I te mutunga, i tutuki ia ki te ISSI IS32FL3738 6×8 dot-matrix LED driver IC, e pai ana ki te pire.E toru o ratou e ranea ana ki te taraiwa i te roopu o te 100 LED;ka tukuna e ia te mana I2C me te kaha ki te tukutahi i te PWM LED puta noa i nga maramara maha kia kore ai he korikori koretake i waenga i nga LED i runga i nga taraiwa rereke.Kei a tatou katoa a tatou mea tino pai ina tae mai ki nga microcontrollers me te hononga WiFi me [Damien] he tino powhiriwhiri mo te raupapa Esppressif ESP32 me te arahi i te huarahi me te ESP32-WROOM.
Ko tetahi atu take me maarama ko te waea.Ka noho ia LED ki runga i tana ake PCB iti me nga papa e kitea ana, engari ko te whakapiri i nga rama rama 100 he mahi ka taea te haere me te iti o te whakamahere.I whiriwhiria e [Damien] tetahi punaha taketake ma te whakamahi i nga riipene parahi kua whakamataohia e Kapton (he rauemi tino pai me te hitori kino).he auahi ake i te hoko ki te waea.
Ko te putunga 3D kua taia e whakamahi ana i te pepa tarai ki te whakamaarama i te rama ka oti te taputapu, ka hangaia he matrix 20 x 5 o nga tapawha e whakahaerea takitahi ana e whiti ana me te riterite.He rawe te hua mutunga ka kite koe i te mahi i roto i te ataata poto i raro nei.
Mena kei te anga koe ki tetahi hiahia mana whakahaere matrix LED, kia mohio koe ki te panui i tenei aratohu mana matrix LED ka kitea e koe etahi tohutohu awhina.
"I te mutunga ka kitea e ia he IS32FL3738 6×8 dot-matrix LED taraiwa IC mai i ISSI [http://www.issi.com/US/index.shtml] a he pai ki te pire," e kii ana a Donald Papp.
Ko te IS32FL3738 he mea hangaia e Lumissil, he wehenga motuhake o ISSI [Integrated Silicon Solution Inc]. I whakaingoatia a Lumissil i te 20-Maehe-2020 [1] a i mohiotia i mua ko ISSI AMS [AMS > Analog and Mixed Signal division].
