Izvo zvese zvakatanga apo [Damien Walsh] akawana mamwe mabhodhi e LED akasara.Imwe neimwe pani ine 100 diki inopenya LED edunhu mabhodhi ayo anogona kuparadzaniswa kana zvichidikanwa.[Damien] aive nezano riri nani: zvichengete mu 20 × 5 array uye gadzira mutyairi wekudzora LED yega yega pamusoro peWiFi.Akabudirira (pfupi post-hiatus demo vhidhiyo yakawedzerwa pazasi) uye akapa mamwe mazano anofadza pamaitiro ekuvaka kubva pakutanga.
Chipingamupinyi chaakatanga kusangana nacho ndicho icho vazhinji vedu tinogona kufunga nezvacho.Zvakaoma kutsvagisa chimwe chinhu kana iwe usingazive izwi chairo.Muchiitiko cha[Damien], kutsvaga kwake kwakamuendesa kune cornucopia yemadhiraivha eLED yekuvhenekesa mukati kana kuvheneka.Midziyo iyi inoita kuti ma LED madiki akawanda aite sechinhu chimwe chikuru chechiedza, asi anoda kukwanisa kushanda nemumwe nemumwe wavo.
Pakupedzisira, akagumburwa neISSI's IS32FL3738 6 × 8 dot-matrix LED mutyairi IC, iyo inokodzera bhiri.Vatatu vavo vakakwana kutyaira pani ye100 LEDs;inopa I2C kutonga uye inotokwanisa kuyananisa LED PWM kune akawanda machipi kuitira kuti pasave nekupenyereka kusingaenderane pakati pemaLED pane akasiyana madhiraivha.Tese tine zvatinoda kana zvasvika kune microcontrollers uye WiFi yekubatanidza uye [Damien] ishamwari huru yeEspressif ESP32 series uye ari kutungamira nzira neESP32-WROOM.
Imwe nyaya inofanirwa kuziva ndeye wiring.Imwe neimwe LED inogara payo yayo diki PCB ine ruoko yakavhurika pads, asi kushambadzira 100 LEDs ibasa rinogona kuenda kure nekuronga kushoma.[Damien] akasarudza yekutanga sisitimu achishandisa mitsetse yeKapton insulated mhangura tepi (chinhu chinoshanda kwazvo chine nhoroondo inosuwisa).inopfungaira kupfuura kutengeswa pawaya.
A 3D akadhindwa baffle anoshandisa bepa rekutsvaga kuparadzira mwenje anopedzisa mudziyo, kugadzira 20 x 5 matrix yemarectangles anodzorwa ega anopenya zvakanaka uye zvakaenzana.Mhedzisiro yacho inotaridzika zvakanaka uye unogona kuiona ichiita muvhidhiyo pfupi pazasi.
Kana iwe wakatarisana neinofanana LED matrix control inodiwa, ive shuwa yekuverenga iyi LED matrix control guide kwaunowana mamwe anobatsira matipi.
"Pakupedzisira akawana IS32FL3738 6 × 8 dot-matrix LED driver IC kubva kuISSI [http://www.issi.com/US/index.shtml] uye inokodzera bhiri," anodaro Donald Papp.
Iyo IS32FL3738 inogadzirwa chaizvo neLumissil, inova chikamu chakazvimirira cheISSI [Integrated Silicon Solution Inc].
