Lcd12864 Suav cov lus qhia (12864 pin piav qhia thiab kev ua haujlwm _ cov yam ntxwv tsis muaj thiab tsav tsheb sib koom)

● Chij Npaws: Tus chij BFBF muab kev khiav haujlwm rau kev khiav haujlwm. BF = 1 qhia tau hais tias tus module yog ua haujlwm sab hauv. Lub sij hawm no, tus qauv tsis txais cov lus qhia sab nraud thiab cov ntaub ntawv. Thaum BF = 0, tus qauv npaj siab txais cov lus qhia sab nraud thiab cov ntaub ntawv txhua lub sijhawm. Nrog STATUSRD kev qhia, BF tuaj yeem nyeem rau lub npav DB7 kom paub tseeb tias tus txheejtxheem kev khiav haujlwm.

● Font cim ROM (CGROM) Font cim ROM (CGROM) qhia 8192 Qhov no txhais tau siv los tswj qhov kev tshuaj ntsuam ntawm qhov module. DFF = 1 TSIS MUAJ HNUB NYOOG, DDRAM cov ntsiab lus muaj nyob rau ntawm qhov screen, DFF = 0 DISPLAY OFF. Tus txheej xwm ntawm DFF yog tswj los ntawm cov lus txib DISPLAYON / OFF thiab RST cov cim qhia.

● Cov ntaub ntawv qhia txog RAM (DDRAM) module nrog cov lus qhia hauv RAM muab 64 x 2 bytes ntawm qhov chaw, mus txog 4 kab ntawm 16 lo lus (64 lo lus) nyob rau hauv Suav font zaub, thaum sau ntawv rau cov ntaub ntawv RAM, Tso saib cov npe ntawm CGROM thiab CGRAM feem ntau; no module yuav tso peb hom fonts, uas yog ib nrab-dav alphanumeric (16 * 8), CGRAM font, thiab Suav font ntawm CGROM. Kev xaiv ntawm peb cov ntawv sau raws li DDRAM. Nyob rau ntawm qhov kev xaiv hom ntawv sau ua lus Suav, qhov kev cai font ntawm CGRAM yuav raug xaiv nyob rau hauv qhov encoding ntawm 0000H-0006H (cov lis dej num ntawd yog 0000, 0002, 0004, thiab 0006), thiab ib nrab-dav alphanumeric cim yuav xaiv tau nyob rau hauv 02H-7FH encoding. Lub font, ntawm txoj cai nyob saum A1 yuav raug txiav nrog lub byte tom ntej, thiab qhov encoding ntawm ob bytes ua tus Suav ua cim code BIG5 (A140-D75F), GB (A1A0-F7FFH).

● Font cim RAM (CGRAM) font generation RAM muab duab txhais (lo lus tsev) muaj nuj nqi, uas yuav muab plaub pab pawg ntawm 16 × 16 cov ntsiab lus ntawm cov duab tshwj xeeb. Cov neeg siv yuav muab cov duab cim tsis yog los ntawm cov ntawv sau sab nraud. Hom yog self-defined rau CGRAM thiab tuaj yeem tshwm rau ntawm qhov screen los ntawm DDRAM raws li sau hauv CGROM.

● Qhov chaw nyob tiv thaiv AC qhov chaw nyob yog siv los khaws qhov chaw nyob ntawm ib qho ntawm DDRAM / CGRAM. Nws tuaj yeem hloov tau los ntawm lub chaw teev npe qhia ntawv. Tom qab, yog tias tus nqi DDRAM / CGRAM nyeem lossis sau ntawv, qhov nqi ntawm qhov chaw nyob yuav ntxiv rau ib qho. Thaum RS yog "0" thiab R / W yog "1", tus nqi ntawm qhov chaw nyob hauv ntawv yog nyeem rau DB6 - DB0.

Cursor / flicker tswj kev sib cog lus

Qhov module no muab ib tus cursor kho vajtse thiab lub nrig txog kev tswj ntawm qhov muag uas qhia txog tus cursor los yog ntsais ntawm lub DDRAM los ntawm tus nqi ntawm qhov chaw nyob.

LCd12864 cov lus qhia

Lcd12864 Suav cov ntaub ntawv ntsiab lus (12864 pin piav qhia thiab kev ua haujlwm _features tsis thiab tsav tsheb sib koom)

Lus Cim: Ua ntej IC1 txais cov kev qhia, tus microprocessor yuav tsum paub tseeb tias lub tsev yog nyob rau hauv ib qho mob tsis heev. Thaum nyeem ntawv BF chij, BF yuav tsum xoom los txais cov lus qhia tshiab; yog tias tsis muaj kev ntsuam xyuas ua ntej xa ntawv qhia Cov khauj khaum BF yuav tsum tau muab ncua ntev ntev ntawm qhov kev qhia dhau los thiab kev qhia, uas yog, tos txog kev qhia dhau los yuav tsum tau ua tiav.

Lcd12864 daim ntawv thov piv txwv

1. Kev npaj ua ntej siv: Siv qhov kev ua haujlwm ua haujlwm rau lub module ua ntej, thiab mam li kho qhov sib txawv ntawm lub LCD raws li txoj kev txuas hauv daim duab hauv qab no kom pom tias dub qab duab. Txoj kev no tseem tuaj yeem kuaj xyuas seb qhov chaw seem hauv LCD puas ploj lawm.

2. Ximxoo zaub: 128X64-0402B nrog Suav lub tsev qiv ntawv tuaj yeem tso saib 4 kab thiab 8 kab ntawm 32 cim nrog 16 16 dot matrix ib qho screen. Txhua cov duab RAM tau tso saib 1 Suav ua cim los yog 2 16 × 8 lattice tag nrho heights. ASCII cim, uas tuaj yeem tso siab txog 32 Cov Neeg Suav los sis 64 ASCII cim rau ib qho screen. Lub 128X64-0402B nrog Chaav ntawv qiv ntawv ntxiv hauv qab no muab ib 128 x 2 byte cim zaub RAM tsis (DDRAM). Cov cim zaub yog tiav los ntawm kev sau cov cim cim leb rau hauv cov cim ua cim RAM. Nyob ntawm cov ntsiab lus ntawm kev sau ntawv, tus txheem ntawm CGROM (Suav ntawv qiv ntawv), HCGROM (ASCII font font), thiab CGRAM (kev cai font) tuaj yeem tshwm rau LCD npo. Peb txawv cim / xim xaiv code ntau: 0000 ~ 0006H (qhov chaws yog 0000,0002,0004,0006 tag nrho ntawm 4) tso saib kev cai font, 02H ~ 7FH zaub ib nrab-ASCII code cim, A1A0H ~ F7FFH qhia 8192 GB2312 font fonts. Lub cim qhia tau hais tias qhov chaw nyob 80H mus rau 9FH ntawm RAM hauv cov kua siv lead ua kua. Qhov chaw nyob ntawm RAM pom los ntawm cov ua cim tau muaj ib-rau-ib tsab ntawv nrog 32-cim zaub thaj tsam. Cov ntawv xov xwm muaj qhia nyob hauv qab rooj.

3, daim duab nraaj

Thawj kauj vertical qhov chaw nyob thiab tom qab teeb tsa qhov chaw nyob kab lus (sau ob tug bytes ntawm cov ntaub ntawv los ua kom tiav cov laj kab ntsig thiab kab sib chaws)

Vertical chaw ntau yam AC5. .06

Kab rov tav chaw nyob AC3 ... AC0

Qhov chaw txee (AC) ntawm daim duab RAM yuav tsuas yog nce qhov chaw nyob ntawm kab (X-axis). Thaum qhov chaw nyob ntawm kab lus = 0FH, nws yuav pib dua rau 00H, tiam sis nws yuav tsis cia qhov nce qhov chaw nyob ntawm ib qho. Yog li, thaum sau qhov chaw nyob tsis tu ncua, Thaum muaj ntaub ntawv ntau ntau, qhov kev zov me nyuam yuav tsum txiav txim siab seb qhov chaw nyob ntsiag to yuav tsum pib dua. GDRAM coordinate chaw nyob thiab ntaub ntawv cov lus qhia raws li qhia nram qab no:

4, kev piav qhia cov npe

Thaum siv lub 128X64 zaub module nrog lub Chaw Qiv Ntawv Nkauj, nco qab cov lus nram qab no:

1 Thaum koj xav pom cov cim suav nyob rau hauv ib txoj hauj lwm, koj yuav tsum xub teeb tsa cov yeeb yaj duab cim, uas yog, teev cov ntaub ntawv chaw nyob ua ntej, thiab tom qab ntawd sau cov cim Suav.

2 Tus txheej txheem ntawm kev nthuav qhia ASCII ntawv yog tib yam li txheej txheem ntawm kev nthuav qhia cov cim Suav. Txawm li cas los xij, thaum tso cov cim nruam, koj tsuas yog xav muab qhov chaw nyob ib zaug. Module ntxiv ntxiv 1 mus rau tus cim tom ntej. Txwv tsis pub, tus tso tawm tus cim yuav muaj ib qho ASCII cim chaw.

3 Thaum cov cim code 2 bytes, cov qaum npej ntawm yuav tsum tau sau ua ntej, raws li cov qis tshaj.

4 Ua ntej lub module tau txais kev qhia, tus processor yuav tsum paub tseeb tias qhov module yog nyob rau hauv lub xeev tsis muaj kev txwv. Ntawd yog, thaum BF chij nyeem, BF yuav tsum "0" los txais cov kev qhia tshiab. Yog tias BF chij tsis tau kuaj ua ntej xa ntawv qhia, nws yuav tsum tau ncua ntev ntev ntawm qhov kev qhia dhau los thiab kev qhia, uas yog, tos txog kev qhia dhau los los txiav txim tias qhov kev ua tiav tiav. Rau lub sijhawm kawm tiav, saib cov lus qhia tiav lub sijhawm ua haujlwm hauv cov lus qhia. 5 "RE" yog qhov kev txiav txim siab tswj me ntsis rau cov kev qhia yooj yim thiab cov kev qhia ntxiv. Thaum "RE" hloov lawm, cov kev qhia tom ntej yuav nyob hauv lub xeem dhau tshwj tsis yog tias "RE" hloov dua tshiab. Thaum siv tib qho kev qhia, nws tsis tas yuav pib dua qhov "RE" txhua zaus.
