Cov kua siv lead ua kua (LCD) tau siv dav hauv ntau yam khoom siv hluav taws xob, thiab nws cov txheej txheem coding yog ib kauj ruam tseem ceeb kom paub txog kev ua haujlwm. Ua ntej, koj yuav tsum nkag siab txog cov qauv yooj yim thiab kev ua haujlwm ntawm LCD. Cov kua siv lead ua kua molecules hloov lawv cov kev npaj nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, yog li cuam tshuam rau txoj kev ntawm lub teeb, thiab cov yam ntxwv no yog siv los tso saib dluab.
Thawj kauj ruam nyob rau hauv cov txheej txheem coding yog pib cov zaub. Koj yuav tsum tau teeb tsa cov ntawv teev npe ntawm lub moos hluav taws xob cov khoom siv, suav nrog hom zaub, lub sijhawm tsis ua haujlwm, thiab lwm yam. Feem ntau, cov cai pib yog muab los ntawm cov chaw tsim khoom thiab tuaj yeem hloov kho kom haum raws li cov qauv tshwj xeeb.
Tom ntej no yog kev xa cov ntaub ntawv duab. Cov duab feem ntau yog khaws cia rau hauv lub cim xeeb hauv daim ntawv ntawm cov thav ntawv thiab tom qab ntawd hloov mus rau cov xim hluav taws xob moos cov kab los ntawm kab. Txhawm rau kom muaj kev ruaj ntseg ntawm cov ntaub ntawv xa mus, lub sijhawm yuav tsum tau ua raws li nruj me ntsis, suav nrog cov cim ntawm kab synchronization cov cim thiab thav duab synchronization teeb liab.
Thaum lub sij hawm coding txheej txheem, nws yog ib qho tseem ceeb los xaiv ib lub tsev qiv ntawv tsav tsheb tsim nyog. Cov tsev qiv ntawv feem ntau siv xws li Adafruit GFX, u8g2, thiab lwm yam. Cov tsev qiv ntawv no muab cov API nplua nuj, ua haujlwm xws li duab kos duab thiab cov ntawv nyeem yooj yim. Nyob rau tib lub sijhawm, cov zaub tsis yuav tsum tau teeb tsa kom tsim nyog los txhim kho kev ua haujlwm zoo.
Thaum kawg, debugging yog ib feem tseem ceeb ntawm coding. Siv lub logic analyzer lossis oscilloscope los saib xyuas lub teeb liab waveform tuaj yeem pab nrhiav thiab daws teeb meem lub sijhawm. Tsis tas li ntawd, siv cov ntsiab lus tawg thiab cov txheej txheem luam ntawv tuaj yeem pab nrhiav thiab kho qhov yuam kev hauv cov cai.
Los ntawm kev tshawb fawb coding thiab debugging, cov zaub ua tau zoo ntawm Multi-function xim hluav taws xob moos tuaj yeem siv tau los coj cov neeg siv kev paub pom zoo.
