Video: Ntxiv CS Pin rau ST7789 1.3 "IPS LCD: 5 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26
Tsis ntev los no kuv tau hla tus nqi qis 1.3 IPS TFT screen. Nws muaj qhov kev daws teeb meem siab heev ntawm 240x240 pixels thiab siab pixel siab heev vim nws qhov me me. Nws yog IPS vaj huam sib luag, IPS sawv cev rau InPlane Hloov. Cov ntxaij vab tshaus LCD uas muaj lub kaum ntse ntse saib thiab ua kom xim zoo dua li ib txwm TFT+TN/CSTN hom LCD's. Yog vim li cas nws yog ib qho kuv nyiam LCDs.
Nws siv SPI Kev Sib Tham los sib tham nrog lub microcontroller lossis SOC.
Txuj SPI siv 4 xov hlau los sib txuas lus:
1) MOSI -> Master Out Slave In
2) MISO -> Master in Slave Out
3) SCK -> Serial Moos
4) CS/SS -> Chip Select/Slave Select
SPI tso cai rau ntau yam khoom siv hauv tsheb npav thiab cov cuab yeej siv tau raug xaiv los ntawm rub tus nti xaiv kab LOW. Cov zaub no tsis muaj cov kab xaiv kab tawg tawm rau lub taub hau.
Koj yuav nug yog vim li cas thab thab hack CS kab? Zoo uas nyob ntawm daim ntawv thov. Yog tias koj muaj cov khoom siv tsuas yog ntaus ntawv ntawm SPI tsheb npav ces qhov ntawd zoo. Cov zaub tseem yuav ua haujlwm, txawm hais tias yog koj xav siv qee lub cuab yeej ntawm lub npav SPI xws li daim npav SD daim npav ces koj tsis muaj hmoo vim lawv ob leeg xav tau cais kab CS txhawm rau tham nrog tus qhev ntaus ntawv. Tias yog vim li cas peb yuav tau txais kab CS tawm ntawm tus qauv.
Cov qauv no muaj tag nrho ntawm 7 tus pin:
1) BLK = Backlight
2) D/C = Data/Command
3) RES = Pib dua
4) SDA = Serial Data lossis SPI MOSI
5) SCL = Serial Clock lossis SPI SCK
(Tsis txhob poob siab nrog I2C pins SDA thiab SCK, lub vijtsam no tsis yog I2C.)
6) VCC (3.3V)
7) Hauv av
Los ntawm kev txuas BLK tus pin rau VCC peb tuaj yeem ua kom lub teeb pom kev zoo ntawm lub vijtsam tab sis tus pin no tsis muaj txiaj ntsig tshwj tsis yog tias koj xav tswj lub teeb pom kev zoo los ntawm software. Tab sis peb tuaj yeem siv tus lej txuas ntxiv no ua tus pin CS los ntawm kev tshem tawm cov kab ntawm kab ntawm LCD.
Khoom siv
1) Ntse txiav los yog riam.
2) Soldering Hlau
3) Jumper hlau lossis xaim qhwv cov xov hlau (> 28AWG)
4) Kub kua nplaum phom (Tsis teb los tau)
Kauj Ruam 1: cuam tshuam Thawj Zaug
Ua ntej koj tus kheej yog tus txiav ntse. Tom qab ntawv txiav cov kab raws li qhia hauv daim duab. Ua qhov no kom zoo zoo vim tias lub vijtsam tsis tawg thiab tsis txhob cia lub tshuab txiav plam thiab ua rau cov hlua hlua puas. Tom qab cuam tshuam cov kab kom paub tseeb tias tus pin BLK tau txuas nrog los ntawm tus tiv thaiv R2 hauv qab kab ntawv no nrog kev pab los ntawm multimeter hauv hom txuas ntxiv.
Kauj Ruam 2: Ntxiv Cov Puab Tsuag
Ib zaug ntxiv nrog kev pab ntawm tus txiav, ua tib zoo khawb daim npog qhov muag ntawm peb qhov chaw uas qhia hauv daim duab. Ceev faj tsis txhob nthuav tawm cov neeg nyob ib puag ncig, ua li ntawd yuav ua rau cov khoom siv tawv dua tom qab. Khawb nws kom txog thaum koj pom cov tooj liab liab. Nws yuav tsum loj txaus kom xaim cov xov hluav taws xob uas peb yuav muab tom qab.
Tom qab ntawd tin cov paug tooj liab uas tau nthuav tawm no nrog qee qhov tshiab solder.
Kauj Ruam 3: cuam tshuam Qhov Tseeb Thib Ob
Kuv pom zoo siv qhov ntsuas kub tswj hlau rau cov kauj ruam tom ntej. Teem cov hlau kom nyob ib puag ncig 350C kom tsis txhob tawg me me cov ntaub qhwv rau LCD. Kuv yuav siv kuv qhov kev ntseeg TS100 rau qhov no. Pib los ntawm kev ntxiv qee qhov txuas tshiab rau ntawm kab txuas txuas kab laug sab. Thiab pib los ntawm ib sab ib sab maj mam rub daim kab xev sab saud kom tshem cov laug sib koom ua ke ib zaug. Ua siab mos siab muag! Daim kab xev no tsis yooj yim heev. khoov nws ntau dhau yuav ua rau tawg ntawm sab hauv. Tam sim no tom qab tshem daim kab xev, txiav kab ntawv mus los ntawm kab thib 5 los ntawm sab laug. Nov yog peb kab CS, txuas mus tas li rau GND. Txiav raws sab hauv qab ntawm kab los ntawm cov dej nyab hauv av. Tom qab cuam tshuam kom ntseeg tau tias qhov no raug txiav tawm ntawm tus pin GND.
Tom qab nws ua tiav, rov muag cov kab xev rau PCB thiab txheeb xyuas txhua qhov kev sib txuas nrog multimeter.
Kauj Ruam 4: Ntxiv Jumper Wires
Tau txais qee cov xov hlau zoo (cov tub ntxhais pom zoo) thiab muab cov hlua khi tawm. Txuas ib lub xaim los ntawm BLK Header kab mus rau CS kab ntawm kab thiab ib lub xov hlau los ntawm VCC mus rau lub teeb pom kev.
Qhov no yuav khi lub teeb pom kev rov qab rau VCC thiab txuas qhov dawb header rau CS.
Ntxiv qee cov kua nplaum kub ntawm cov xov hlau thiab txuas tom qab kuaj xyuas.
Kauj Ruam 5: Xeem:)
Ntsuas TFT nrog koj nyiam MCU.
