Qhov tsis nkag siab no qhia yuav siv ESP8266/ESP32 thiab LCD li cas kom tsim cov ntab zoo li cov duab ntawm Acrylic duab sawv ntsug.

Kauj ruam 1: Kev npaj

Acrylic Photo Stand

Txhua qhov sawv ntsug acrylic uas loj dua me ntsis ntawm LCD yuav tsum yog. Lub sijhawm no kuv tab tom siv daim duab 3R.

Zaub Zaub

Ib qho Arduino_GFX txhawb LCD zoo, koj tuaj yeem pom tam sim no txhawb cov zaub ntawm GitHub nyeem:

Lub sijhawm no kuv siv YT400S0006 4 ST7796 LCD.

FPC rau DIP PCB hloov pauv pawg thawj coj saib

Qhov no yog nyob ntawm yeem, nyob ntawm koj xaiv LCD, FPC rau DIP PCB hloov pauv pawg thawj coj tuaj yeem pab koj ua kom yooj yim dua. YT400S0006 muaj 40 tus pin 0.5 hli suab FPC. Nws tsis yog ib qho yooj yim soldering ncaj ntawm 0.5 mm suab, yog li kuv siv lub hloov pauv los pab kuv.

ESP8266/ESP32 Dev Board

Txhawm rau ua kom cov zaub ntab zoo li, nws zoo dua siv lub wireless dev board thiab tseem nyiam txhawb nqa Lipo lub zog. Lub sijhawm no kuv tab tom siv TTGO T-base ESP8266 dev board.

Roj teeb lipo

Qhov no yog nyob ntawm yeem, nyob ntawm seb koj yuav siv cov zaub no tsis txuas. Qhov roj teeb loj no txiav txim siab los ntawm 2 yam:

  • cov sijhawm ua haujlwm: piv txwv li yog tias koj xav tau nws tuaj yeem ua haujlwm 2 teev nws yuav tsum yog qee lub sijhawm xws li ~ 250 mA x 2 teev ~ = 500 mAH
  • qhov chaw seem: rau zais tag nrho cov khoom siv tom qab LCD, lub roj teeb loj yuav tsum yog LCD me me rho tawm cov hloov pauv hloov pauv thiab pawg dev

Cov kauj ruam no yog nyob ntawm yeem, nyob ntawm qhov pom lub kaum ntse ntse.

Tsis muaj ze li qhov pom kev txhawj xeeb rau IPS/OLED zaub. Tab sis nws nyuaj rau pom qhov loj me me SPI IPS/OLED zaub hauv kev nyiam ua lag luam.

Rau qhov "dav-lub" zaub zoo li YT400S0006 Kuv tab tom siv, ua tib zoo nyeem cov ntawv ua ntej ua ke. YT400S0006 tus saib lub kaum ntse ntse yog 12 teev, uas txhais tau tias koj yuav tsum tso FPC ntawm sab saud kom pom lub kaum ntse ntse zoo tshaj.

Yog tias koj tseem muaj 12 teev sawv ntxov, nws yuav tsum tau laum thiab kho qhov ntev nyob ntawm sab nraub qaum sab nraub qaum ntawm daim duab kom cia FPC tawm. Koj yuav tsis ua qhov no yog tias koj muaj 3, 6 lossis 9 teev sawv ntxov.

Kauj ruam 3: Kho

Txhim kho lub LCD, hloov pauv lub rooj tsavxwm thiab dev lub rooj nrog qee qhov siv ob npaug. Nco ntsoov daim kab xev yuav tsum tsis txhob npog ib qho DIP pins.

Txuas koj lub LCD rau dev dev.

Nov yog cov piv txwv piv txwv sib txuas:

ESP8266 -> LCD

Vcc -> Vcc, resistor -> LED+

GND -> GND, LED- GPIO 15 -> CS GPIO 5 -> DC (yog tias muaj) RST -> RST GPIO 14 -> SCK GPIO 12 -> MISO (xaiv tau) GPIO 13 -> MOSI / SDA

ESP32 -> LCD

Vcc -> Vcc, resistor -> LED+

GND -> GND, LED- GPIO 5 -> CS GPIO 16 -> DC (yog tias muaj) GPIO 17 -> RST GPIO 18 -> SCK GPIO 19 -> MISO (xaiv tau) GPIO 23 -> MOSI / SDA

Nyeem LCD cov ntaub ntawv rau kev txuas ntxiv, piv txwv. YT400S006 xav tau tus pin 38, 39 thiab 40 txuas rau Vcc rau teeb tsa rau SPI hom.

Koj yuav tsum ntxiv tus tiv thaiv, feem ntau ob peb Ohms rau ob peb puas Ohms, nruab nrab ntawm Vcc thiab LED+ txhawm rau kho qhov ci ci.

Kauj Ruam 5: Plug Lipo (Tsis teb los tau)

Yog tias koj xav siv lub wirelessly no, ntsaws lub roj teeb Lipo thiab kho nws nrog daim kab xev ob npaug.

Koj muaj qhov tsim nyog ntab tso rau tam sim no, nws yog lub sijhawm los sim ntawm ntau pua ntawm IoT cov phiaj xwm.
