Nthawi yotsitsimula: Nthawi yotsitsimutsa ndi zotsatira zoyesera, nthawi yeniyeni yotsitsimutsa idzakhala ndi zolakwika, ndipo zotsatira zenizeni zidzakhalapo. Padzakhala chisokonezo panthawi yotsitsimula padziko lonse lapansi, izi ndizochitika zachilendo.

Kugwiritsa ntchito mphamvu: Zomwe zimagwiritsidwa ntchito ndi mphamvu ndizo zotsatira zoyesera. Kugwiritsa ntchito mphamvu kwenikweni kudzakhala ndi vuto linalake chifukwa cha kukhalapo kwa bolodi la dalaivala komanso momwe mungagwiritsire ntchito. Zotsatira zenizeni zidzapambana.

SPI Communication Time

Popeza chophimba cha inki chimangofunika kuwonetsedwa, chingwe cha data (MISO) chotumizidwa kuchokera kumakina ndikulandiridwa ndi wolandirayo chimabisika apa.

CS: Kapolo chip sankhani, CS ikakhala yotsika, chip chimayatsidwa
DC: pini yolamulira deta/lamulo, lembani lamulo pamene DC=0; lembani deta pamene DC=1

SCLK: Wotchi yolumikizirana ya SPI
SDIN: Mbuye wolankhulana wa SPI amatumiza, kapolo amalandira
Nthawi: CPHL=0, CPOL=0 (SPI0)

[Ndemanga] Kuti mudziwe zambiri za SPI, mutha kusaka zambiri pa intaneti.

Ntchito Protocol
Chogulitsachi ndi chipangizo cha E-pepala chomwe chimagwiritsa ntchito ukadaulo wowonetsera zithunzi wa Microencapsulated Electrophoretic Display, MED. Njira yoyamba ndiyo kupanga timizere ting'onoting'ono, momwe ma pigment amtundu wakuda amayimitsidwa mumafuta owonekera ndipo amatha kusuntha kutengera mtengo wamagetsi. Chojambula cha E-paper chikuwonetsa mawonekedwe powunikira kuwala kozungulira, kotero sichifunikira kuwala koyambira. (Dziwani kuti pepala la e-Paper silingathandizire kusinthidwa mwachindunji padzuwa).

Momwe mungatanthauzire ma pixel
Mu chithunzi cha monochrome timatanthauzira ma pixel, 0 ndi wakuda ndi 1 ndi woyera.

Choyera: □: Pang'ono 1
Black: ■: Pang'ono 0

Dontho lomwe lili pachithunzichi limatchedwa pixel. Monga tikudziwira, 1 ndi 0 amagwiritsidwa ntchito kutanthauzira mtundu, chifukwa chake titha kugwiritsa ntchito pang'ono kutanthauzira mtundu wa pixel imodzi, ndi 1 byte = 8pixels Kwa ex.ample, Ngati tiyika ma pixel oyambilira kukhala akuda ndi ma pixel omaliza 8 kukhala oyera, tikuwonetsa ndi ma code, adzakhala 8-bit monga pansipa:

Kusamalitsa

Pazithunzi za E-paper zomwe zimathandizira kutsitsimula pang'ono, chonde dziwani kuti simungathe kuwatsitsimutsa ndi mawonekedwe otsitsimula pang'ono nthawi zonse. Mukatsitsimula pang'ono kangapo, muyenera kutsitsimutsanso EPD kamodzi. Apo ayi, zotsatira zowonetsera zidzakhala zachilendo, zomwe sizingakonzedwe!

Ndizochitika zachilendo kuti EPD yamitundu itatu idzakhala ndi kusiyana kwamitundu m'magulu osiyanasiyana. Chifukwa chake, Ndikoyenera kugwiritsa ntchito pulogalamuyi kuchotsa zithunzi zonse pa EPD ndikuyisunga ikuyang'ana m'mwamba. Chonde yeretsani chinsalu kangapo musanayatse.
Dziwani kuti chophimba sichikhoza kuyatsidwa kwa nthawi yayitali. Chinsalucho chikapanda kutsitsimutsidwa, chonde ikani chinsalucho kuti chigone kapena muzimitsa. Apo ayi, chinsalucho chidzakhalabe chokwera kwambiritage state kwa nthawi yayitali, zomwe zingawononge e-Paper ndipo sizingakonzedwe!

Mukamagwiritsa ntchito chiwonetsero cha e-Paper, tikulimbikitsidwa kuti nthawi yotsitsimula ikhale yosachepera 180s, ndikutsitsimutsani kamodzi pa maola 24 aliwonse. Ngati e-Paper sagwiritsidwa ntchito kwa nthawi yayitali, muyenera kugwiritsa ntchito pulogalamuyo kuti muchotse chinsalu musanachisunge. (Onani tsatanetsatane wa zofunikira za malo osungira.)
Chinsalucho chikalowa m'malo ogona, deta yotumizidwa idzanyalanyazidwa, ndipo ikhoza kutsitsimutsidwa kawirikawiri pokhapokha mutayambiranso.

Yang'anirani 0x3C kapena 0x50 (onani zidziwitso kuti mudziwe zambiri) kuti musinthe mtundu wamalire. Muchiwonetsero, mutha kusintha kaundula wa Border Waveform Control kapena VCOM NDI DATA INTERVAL SETTING kuti muyike malire.
Ngati muwona kuti chithunzi chomwe chinapangidwa chikuwonetsedwa molakwika pazenera, tikulimbikitsidwa kuti muwone ngati mawonekedwe a kukula kwa chithunzi ndi olondola, sinthani mawonekedwe a m'lifupi ndi kutalika kwa chithunzicho ndikuyesanso.

VoltagMawonekedwe a e-Paper ndi 3.3V. Ngati mugula gulu laiwisi ndipo muyenera kuwonjezera gawo losinthira kuti ligwirizane ndi 5V voltage. Mtundu watsopano wa dalaivala bolodi (V2.1 ndi matembenuzidwe wotsatira) wawonjezera gawo lowongolera, lomwe limatha kuthandizira onse 3.3V ndi 5V. Mtundu wakale umangothandizira malo ogwirira ntchito a 3.3V. Mukhoza kutsimikizira Baibulo musanagwiritse ntchito. (Yemwe ali ndi 20-pin chip pa PCB nthawi zambiri ndiye mtundu watsopano.)
Chingwe cha FPC cha chinsalucho ndi chosalimba, tcherani khutu kupindika chingwecho molunjika pazenera mukachigwiritsa ntchito, ndipo musamapindire chingwecho molunjika pazenera.

Chophimba cha e-Paper ndichosalimba, chonde yesetsani kupewa kugwa, kugunda, ndikukankha mwamphamvu.
Timalimbikitsa makasitomala kugwiritsa ntchito sample pulogalamu yoperekedwa ndi ife kuyesa ndi gulu lolingana lachitukuko.

RPi Pico

Kulumikizana kwa Hardware
Chonde samalani mayendedwe polumikiza Pico. Chizindikiro cha doko la USB chimasindikizidwa kuti chiwonetse chikwatu, mutha kuwonanso mapini. Ngati mukufuna kulumikiza bolodi ndi chingwe cha pini 8, mutha kulozera ku tebulo ili m'munsimu:

e-Paper	Pico	Kufotokozera
Chithunzi cha VCC	Zithunzi za VSYS	Kulowetsa mphamvu

Zindikirani, Muyenera kukhazikitsanso hardware kapena kugwiritsa ntchito kuyambitsa kudzutsa e-Paper kuchokera ku kugona xxx ndi mtundu wa e-Paper, kale.ample, ngati mugwiritsa ntchito 2.13inch e-Paper D, iyenera kukhala EPD_2IN13D_Sleep().

Application Programming Interface
Timapereka ntchito zoyambira za GUI zoyesa, monga chojambula, mzere, chingwe, ndi zina zotero. Ntchito ya GUI ingapezeke m'ndandanda: RaspberryPi_JetsonNano\c\lib\GUI\GUI_Paint.c(.h).

Mafonti omwe amagwiritsidwa ntchito angapezeke m'ndandanda: RaspberryPi_JetsonNano\c\lib\Fonts.

Pangani chithunzi chatsopano, mutha kuyika dzina lachithunzicho, m'lifupi, kutalika, kuzungulira ngodya, ndi mtundu.

Sankhani bafa ya zithunzi: Mutha kupanga zosungira zithunzi zingapo nthawi imodzi ndikusankha ina ndikujambula ndi ntchitoyi.

Sinthani chithunzi: Muyenera kukhazikitsa mawonekedwe ozungulira a chithunzi, ntchitoyi iyenera kugwiritsidwa ntchito pambuyo pa Paint_SelectImage(). Ngodya ikhoza kukhala 0, 90, 180, kapena 270.

【Zindikirani】 Pambuyo pozungulira, malo a pixel yoyamba ndi osiyana, timatenga pepala la e-inch 1.54 ngati ex.ample.

galasi lachithunzi: Ntchitoyi imagwiritsidwa ntchito kukhazikitsa galasi lachithunzi.

Khazikitsani malo ndi mtundu wa ma pixel: Iyi ndiye ntchito yayikulu ya GUI, imagwiritsidwa ntchito kuyika malo ndi mtundu wa pixel mu buffer.

Kuwonetseratu: Kuyika mtundu wa chithunzi, ntchitoyi imagwiritsidwa ntchito nthawi zonse kuchotsa chiwonetsero.

Mtundu wa mawindo: Ntchitoyi imagwiritsidwa ntchito kuyika mtundu wa mawindo, nthawi zonse imagwiritsidwa ntchito pokonzanso madera monga kuwonetsa wotchi.

Jambulani mfundo: Jambulani mfundo pamalo (X point, Y point) ya buffer ya chithunzi, mutha kusintha mtundu, kukula, ndi masitayilo.

Jambulani mzere: Jambulani mzere kuchokera ku (Xstart, Ystart) kupita ku (Xend, Yend) mu buffer yazithunzi, mutha kukonza mtundu, m'lifupi, ndi kalembedwe.

Jambulani rectangle: Jambulani kakona kuchokera ku (Xstart, Ystart) kupita ku (Xend, Yend), mutha kusintha mtundu, m'lifupi, ndi masitayilo.

Jambulani bwalo: Jambulani bwalo muzotchinga zazithunzi, gwiritsani ntchito (X_Center Y_Center) ngati pakati ndi Radius ngati utali wozungulira. Mutha kusintha mtundu, m'lifupi mwa mzere, ndi kalembedwe ka bwalo.
