Xav txog cov ntaub ntawv tseem ceeb uas yuav tsum muaj los nthuav tawm ntawm cov kev cai LCD thiab kev ua ke ntawm alphanumeric thiab kev cai icons tsim nyog los kho lub LCD.
2. To taub qhov chaw uas lub LCD xav tau kev ua haujlwm. Kev khiav hauj lwm muaj qhov kub thiab txias tuaj yeem cuam tshuam txog qhov zoo ntawm LCD thiab txo qis cov hom ntawm LCD uas yuav siv tau.
3. Pom seb muaj pes tsawg ntawm cov ntawv tsim nyog kom ua tau raws li qhov xav tau ntawm LCD, thiab xaiv qhov tsim nyog LCDPIC microcontroller nrog rau PIC microcontroller LCD.
4. Tsim kos duab / kos duab kos duab thiab sau cov lus qhia rau cov kev cai LCDs thiab to taub qhov pinout ntawm lub LCD.
(Vim tias tsis muaj kev txwv tias qhov thaiv ntawm qhov hluav taws xob ntawm cov electrode thiab qhov thaiv ntawm lub tshooj electrode tsis nyob rau hauv ib lub dav hlau, nws yog qhov zoo los ua tus muab nkag rau tus kheej los ntawm cov chaw tsim khoom.)
5. Xa cov ntawv teev cov lus qhia hauv LCD thiab cov lus qhia rau yam tsawg 3 cov khoom siv rau kev sau cov ntaub ntawv los txiav txim siab txog them nqi, sijhawm, thiab zoo. Coj hauv cov nyiaj tag nrho NRE, nqe tus nqi, thiab nqi tes. Pub tsawg kawg yog ob lub lis piam kom tiav cov duab kos duab thiab tus pin assignments, nrog rau cov duab kos.
6. Tus xub thawj prototype LCD tiv tauj kom raug xa kom tsim nyog LCD tsim thiab kev ua haujlwm zoo hauv daim phiaj xwm thov.
Feem ntau muab 4-6 lub lis piam tso tseg. Rau kev tso cai kawg ntawm kev kos duab thiab tus pin assignments. Tus thawj LCD tsab ntawv xa tuaj tom qab pom zoo.
7. Thaum koj tau txais daim ntawv prototype, koj yuav tsum paub meej tias nws txoj haujlwm ua ntej koj tuaj yeem ua tiav kev pom zoo thiab pib ua LCD.
Lus Cim: Khaws ib daim qauv ntawm tag nrho cov khoom sib pauv ntawm ob tog (xws li daim duab thaij duab, cov duab kos, thiab cov qauv tawm tswv yim) los xyuas kom tau cov ntaub ntawv khaws tseg.
