FUNCTION DESCRIPTION

System Interface

• Iyi chip ine marudzi maviri emhando dzekubatanidza neMPU: 4-bit bhazi uye 8-bit bhazi. 4-bit bhazi uye 8-bit bhazi anosarudzwa neDL bit murejista yekuraira.

Mureza Wakabatikana (BF)

• Kana BF = "Yakakwirira", inoratidza kuti kushanda kwemukati kuri kugadziriswa. Saka panguva ino, murayiridzo unotevera haugoni kugamuchirwa.
• BF inogona kuverengwa, kana RS = Yakaderera uye R/W = Yakakwirira (Verenga Instruction Operation), kuburikidza neDB7 port. Usati waita rairo inotevera, iva nechokwadi chekuti BF haina kukwirira.

Kero Kaunda (AC)

• Kero Counter (AC) inochengetedza DDRAM/CGRAM kero, inotamiswa kubva kuIR. Mushure mekunyora mu (kuverenga kubva) DDRAM/CGRAM, AC inowedzerwa otomatiki (yakadzikira) ne1.
• Apo RS = "Low" uye R / W = "High", AC inogona kuverengwa kuburikidza neDB0 - DB6 ports.

Ratidza Data RAM (DDRAM)

• Zvitoro zveDDRAM zvinoratidzira data inodarika 80 x 8 bits (mavara makumi masere). DDRAM kero yakaiswa pakaunda yekero (AC) senhamba yehexadecimal.

CGROM (Character Generator ROM)

• CGROM ine 5 x 8 dots 204 mavara pateni uye 5 x 10 dots 32 mavara pateni. CGROM ine 204 mavara mapatani e5 x 8 dots.

CGRAM (Character Generator RAM)

• CGRAM ine kusvika ku5 × 8 madotsi, 8 mavara. Nekunyora font data kuCGRAM, mavara-anotsanangurwa mushandisi anogona kushandiswa.

Hukama pakati peCGRAM Kero, Character Codes (DDRAM), uye Character mapatani (CGRAM Data)

Notes:

1. Character code bits 0 kusvika 2 inoenderana neCGRAM kero bits 3 kusvika 5 (3 bits: 8 marudzi).
2. CGRAM inodhinda mabhiti 0 kusvika 2 uye inosarudza chimiro chemaitiro mutsara chinzvimbo. Mutsara wechisere ndiyo nzvimbo yecursor uye kuratidzwa kwayo kunoumbwa neine musoro OR ine chituri. Chengetedza iyo 8th mutsara data, inoenderana nenzvimbo yekuratidzira cursor, pa8 sechiratidziro checursor. Kana iyo 0th mutsara data iri 8, 1 bit inovhenekera mutsara wechisere zvisinei nekuvepo kwecursor.
3. Hunhu patani mitsara zvinzvimbo zvinoenderana neCGRAM data bits 0 kusvika 4 (bit 4 iri kuruboshwe).
4. Sezvinoratidzwa muTable, CGRAM maitiro emhando anosarudzwa kana kodhi yemhando bits 4 kusvika 7 ese ari 0. Zvisinei, sezvo character code bit 3 isina chayakaita, R display ex.ampLe pamusoro inogona kusarudzwa nekodhi yemhando 00H kana 08H.
5. 1 yeCGRAM data inoenderana nekuratidzira kusarudzwa uye 0 yekusasarudzwa Inoratidza hapana mhedzisiro.

Cursor/Blink Control Circuit

Iyo inodzora cursor / blink ON / OFF panzvimbo yecursor.

Tsanangudzo Yemirayiridzo

Outline

• Kuti ukunde mutsauko wekumhanya pakati pewachi yemukati yeS6A0069 neMPU wachi, S6A0069 inoita mashandiro emukati nekuchengetedza kutonga mumafomati kuIR kana DR.
• Iko kushanda kwemukati kunotemerwa zvinoenderana nechiratidzo kubva kuMPU, inoumbwa nekuverenga / kunyora uye data bhasi (Tarisa kune Tafura 7).

Mirayiridzo inogona kukamurwa zvakanyanya mumapoka mana:

1. S6A0069 basa seti mirairo (seta nzira dzekuratidzira, seta data kureba, nezvimwewo)
2. Kero set mirairo kune yemukati RAM
3. Mirayiridzo yekufambisa data ine RAM yemukati
4. Vamwe

• Kero yemukati RAM inowedzerwa kana kuderedzwa ne1.
• Cherechedza: panguva yekushanda kwemukati, mureza wakabatikana (DB7) unoverengwa "Pamusoro".
• Kutarisa mureza kwakabatikana kunofanirwa kutangirwa nerairo rinotevera.

Kungwarira pakushandisa LCD/LCM

• LCD/LCM inounganidzwa uye inogadziriswa nehupamhi hwepamusoro.
• Usaedza kuita chero shanduko kana kugadzirisa.
• Zvinotevera zvinofanira kucherechedzwa.

General Precautions:

1. LCD panel yakagadzirwa negirazi. Dzivisa kunyanya kuvhundutsa kwemuchina kana kuisa kumanikidza kwakasimba pamusoro penzvimbo yekuratidzira.
2. Iyo polarizer inoshandiswa pachiratidziro chepamusoro inokweshwa uye kukuvadzwa zviri nyore. Kunyanya kuchenjerera kunofanira kutorwa pakubata. Kuchenesa huruva kana tsvina kubva pachiratidziro, pukuta zvinyoro nyoro nedonje, kana zvimwe zvinhu zvakapfava zvakanyikwa neisopropyl doro, ethyl alcohol, kana trichloro tri florothane, usashandise mvura, ketone, kana aromatics, uye usambokwesha zvakasimba.
3. Usadaro tamper nenzira ipi neipi nematabo pamapuranga esimbi.
4. Usaite chero shanduko paPCB usina kubvunza XIAMEM OCULAR
5. Paunenge uchiisa LCM, ita shuwa kuti PCB haisi pasi pekunetsekana sekukotama kana kumonyoroka. Elastomer anobatika akatetepa uye akashaikwa mapixels anogona kuguma kubva kudiki kudikitira chero chinhu.
6. Dzivisa kudzvanya pabezel yesimbi, zvikasadaro iyo elastomer yekubatanidza inogona kukanganisa uye kurasikirwa nekubata, zvichikonzera kushaikwa pixels uye zvakare kukonzera murarabungu pachiratidziro.
7. Chenjera kuti usabata kana kumedza makristasi emvura anogona kubuda kubva musero rakakanganisika. Kana chero mvura yekristaro ikapararira paganda kana zvipfeko, igeze nekukurumidza nesipo nemvura.

Static Electricity Precautions:

1. CMOS-LSI inoshandiswa kune module dunhu; saka vashandisi vanofanirwa kudzika pasi pese paanosangana nemodule.
2. Usabate chero yezvikamu zvinoitisa senge LSI pads; iyo mhangura inotungamira paPCB uye iyo interface terminals ine chero nhengo dzemuviri wemunhu.
3. Usabate materminal ekubatanidza echiratidziro nemaoko asina; zvinokonzeresa kubviswa kana kukanganisa kuvharwa kwematerminals.
4.  Iwo ma modules anofanirwa kuchengetwa mumabhegi e-anti-static kana zvimwe midziyo inopokana neiyo static yekuchengetedza.
5. Masimbi akaiswa pasi zvakanaka chete ndiwo anofanira kushandiswa.
6. Kana electric screwdriver ikashandiswa, inofanira kuiswa pasi uye kudzivirirwa kudzivirira mazhenje.
7. Izvo zvakajairika static kudzivirira matanho anofanirwa kucherechedzwa kune zvipfeko zvebasa uye kushanda mabhenji.
8. Sezvo mhepo yakaoma ichikurudzira kune static, humwe hunyoro hwe50-60% hunokurudzirwa.

Soldering Precautions:

1. Soldering inofanira kuitwa chete paI / O zviteshi.
2. Shandisa ironing irons ine grounding chaiyo uye isina kuvuza.
3. Soldering tembiricha: 280°C+10°C
4.  Soldering nguva: 3 kusvika 4 masekondi.
5. Shandisa eutectic solder ine resin flux kuzadza.
6. Kana iyo flux ikashandiswa, iyo LCD nzvimbo inofanirwa kuchengetedzwa kuti isaparadze flux.
7. Flux yakasara inofanira kubviswa.

Operation Precautions:

1. The viewing angle inogona kugadziriswa nekusiyanisa LCD yekutyaira voltage Vo.
2. Kubva pakashandiswa DC voltage inokonzeresa maitiro emagetsi, ayo anokanganisa chiratidziro, iyo inoshandiswa pulse waveform inofanirwa kunge iine symmetric zvekuti hapana DC chikamu chinosara. Iva nechokwadi chekushandisa yakataurwa voltage.
3. Kutyaira voltage inofanira kuchengetwa mukati mechikamu chakatarwa; kuwandisa voltage achapfupisa kuratidza hupenyu.
4. Nguva yekupindura inowedzera nekuderera kwekushisa.
5. Ratidza ruvara rinogona kukanganiswa patembiricha iri pamusoro pemashandisirwo ayo.
6. Chengetedza tembiricha mukati mechikamu chakatarwa chekushandisa uye kuchengetedza. Kunyanya tembiricha uye hunyoro zvinogona kukonzera kuparara kwepolarization, kupeperetswa kwepolarizer kana kugadzira mabhuru.
7. Kuti uchengetedze kwenguva yakareba kupfuura 40 ° C inodiwa, hunyoro hunofanira kuchengetwa pasi pe60%, uye kudzivisa zuva rakananga.
