Kusanzwisisa 1: Kuchengetedza mari
Kukanganisa kwakajairwa 1: Ndeupi ruvara runofanira kuvhenekerwa nechiratidzo pane pani? Ini pachangu ndinofarira bhuruu, saka sarudza iyo.
Positive solution: Kune mwenje wechiratidzo pamusika, tsvuku, girini, yero, orenji, nezvimwewo, zvisinei nehukuru (pasi pe5MM) uye kurongedza, vanga vakakura kwemakumi emakore, saka mutengo unowanzo kusingasviki makumi mashanu masendi. Chiedza cheblue chiratidzo chakagadzirwa mumakore matatu kana mana apfuura. Kukura kwehunyanzvi uye kugadzikana kwekupa kune hurombo, saka mutengo unodhura zvakapetwa kana kana kashanu. Kana iwe ukagadzira iyo panel stack chiratidzo chemavara pasina zvakakosha, usasarudza bhuruu. Parizvino, mwenje weblue chiratidzo chinowanzo shandiswa muzviitiko zvisingagone kutsiviwa nemamwe mavara, sekuratidza masaini evhidhiyo.
Kukanganisa kwakajairwa 2: Aya ekudhonza-pasi/kudhonza-kumusoro anopikisa anoita kunge asina basa zvakanyanya nemaitiro avo ekuramba. Ingosarudza nhamba 5K.
Positive solution: Muchokwadi, hapana kukosha kwekupokana kwe5K pamusika. Iyo yepedyo ndeye 4.99K (yakarurama 1%), inoteverwa ne5.1K (yakarurama 5%). Mutengo wemutengo wakapetwa ka4 pane we4.7K ine 20% chokwadi. 2 nguva. Iko kupikisa kukosha kwe20% kunyatsopikisa kunongova ne1, 1.5, 2.2, 3.3, 4.7, 6.8 marudzi (kusanganisira nhamba yakawanda ye10); zvimwechetezvo, iyo 20% chaiyo capacitor zvakare ine chete pamusoro akati wandei capacitance kukosha. Kune vanopikisa uye capacitors, kana ukasarudza kukosha kunze kwemhando idzi, unofanira kushandisa kururamisa kwepamusoro, uye mari yacho yakapetwa kaviri. Kana izvo zvinodiwa nekururama zvisina kukura, iyi inodhura marara. Mukuwedzera, kunaka kwe resistors kwakakoshawo. Dzimwe nguva batch yevakaderera resistors inokwana kuparadza purojekiti. Zvinokurudzirwa kuti uzvitenge muzvitoro zvinozviitira wega seLichuang Mall.
Kukanganisa kwakajairika 3: 74XX gedhi redunhu rinogona kushandiswa kune iyi logic, asi yakanyanya kusvibiswa, saka shandisa CPLD, inoita seyakanyanya kukwirira.
Positive solution: 74XX gedhi redunhu rinongova masendi mashomanana, uye CPLD inenge yakawanda yemadhora (GAL / PAL inongova madhora mashomanana, asi haina kukurudzirwa), mari yakawedzera kakawanda, tisingatauri, ndiyo. akadzokera kukugadzira, zvinyorwa, nezvimwe. Wedzera kakawanda basa racho. Pasi pechikonzero chekusakanganisa kushanda, zviri pachena kuti zvakakodzera kushandisa 74XX nepamusoro pekuita mari.
Kukanganisa kwakajairwa 4: Iyo PCB dhizaini inodiwa yebhodhi iyi haina kukwirira, ingoshandisa waya yakatetepa uye wozvironga otomatiki.
Positive mhinduro: Otomatiki wiring ichaita zvisingadzivisiki kutora yakakura PCB nharaunda, uye panguva imwe chete iyo inoburitsa kakawanda vias kupfuura bhuku wiring. In hombe batch zvigadzirwa, PCB vagadziri vane zvinokosha kufunga maererano mutsetse upamhi uye nhamba vias maererano Pricing. , Iwo anokanganisa goho rePCB uye nhamba yezviboorero zvinodyiwa. Mukuwedzera, iyo nzvimbo yePCB board inokanganisawo mutengo. Naizvozvo, otomatiki wiring inosungirwa kuwedzera mutengo wekugadzira wedunhu bhodhi.
Kukanganisa kwakajairwa 5: Yedu sisitimu zvinodiwa zvakakwira zvakanyanya, kusanganisira MEM, CPU, FPGA uye ese machipisi anofanira kusarudza anokurumidza.
Mhinduro yakanaka: Haisi yese chikamu che-high-speed system inoshanda nekumhanya kukuru, uye pese apo kukurumidza kwechigadzirwa kunowedzera nenhanho imwe, mutengo unowedzera zvakapetwa kaviri, uye inewo kukanganisa kukuru pamatambudziko ekutendeseka kwechiratidzo. Nokudaro, pakusarudza chip, zvakakosha kufunga nezvehuwandu hwekushandiswa kwezvikamu zvakasiyana zvechigadziro, pane kushandisa kukurumidza.
Kukanganisa kwakajairwa 6: Chero bedzi chirongwa chakasimba, kodhi refu uye kushanda kwakaderera hazvikoshi.
Positive solution: CPU kumhanya uye memory space zvese zvinotengwa nemari. Kana iwe ukapedza mamwe mazuva mashoma kuti uvandudze mashandiro echirongwa kana uchinyora kodhi, saka mari yekuchengetedza kubva mukudzikisa iyo CPU frequency uye kuderedza ndangariro simba zvechokwadi kwakakosha. Iyo CPLD/FPGA dhizaini yakafanana.
