4. Kushanda kweDisplay Module
Kana yabatanidzwa uye yagadziriswa, chiratidziro cheE-Ink chinoshanda nekugamuchira data kuburikidza neSPI interface kuti chigadzirise zviri mukati macho. Chiratidziro ichi chinotsigira mavara matsvuku, matema, uye machena.
4.1 Kuratidzwa Kwekudzoreredza Nguva
Zviratidziro zveE-Ink zvine kutenderera kwakasiyana kwekudzoreredza. Kune module ye 4.2-inch, kudzoreredza kwakazara kunowanzo tora masekondi angangoita gumi nemashanu. Munguva iyi, chiratidziro chinogona kupenya kana kuratidza mapatani ari pakati sezvo pigments dzichigadziriswa kuti dzigadzire mufananidzo mutsva. Mushure mekudzoreredza, mufananidzo unoramba wakasimba usingashandise simba.
4.2 Kuratidzwa Kwezviri Mukati
Unogona kuratidza mhando dzakasiyana dzezviri mukati, kusanganisira zvinyorwa, mifananidzo, nemifananidzo. Software yakapihwa exampIzvi zvinoratidza maitiro ekugadzirira nekutumira data remufananidzo ku display buffer kuti rionekwe.
Mufananidzo 4: Module yeE-Ink Display Module (B) ine 4.2-inch inoratidza mufananidzo wepanda iri kurara, ichiratidza kugona kwayo kuburitsa mufananidzo.
5. Kuchengeta
Module yekuratidza yeE-Ink inoda kugadziriswa kushoma nekuda kwekugadzirwa kwayo kwakasimba uye simba rayo shoma.
- Kuchenesa: Shandisa jira rakapfava, rakaoma, risingachinji kuti uchenese zvinyoro nyoro nzvimbo yekuratidzwa. Dzivisa kushandisa zvinhu zvinochenesa mvura kana zvinhu zvinokwesha.
- Environmental Conditions: Shandisa uye chengeta module mukati memazinga ayo ekupisa nehunyoro hwakatarwa kuti uve nechokwadi chekuti inoshanda zvakanaka uye inogara kwenguva refu. Dzivisa kuratidzwa nezuva zvakananga kwenguva yakareba, sezvo izvi zvinogona kukanganisa hupenyu hwechiratidziro.
