Kauj Ruam 3: Dot Matrix LED Zaub

Kuv muaj 2 ntawm lawv, 4 ntu txhua, yog li kuv txiav txim siab los ua 8-ntu ib.

Yooj yim muaj 5-tus pin txiv neej lub taub hau ntawm ib sab, thiab sib piv 5 qhov ntawm sab nraud. Khoov tus txiv neej lub taub hau rau hauv cov khoom zoo li] cov duab, Kuv muaj peev xwm txuas ob lub qauv ob qho tib si hluav taws xob thiab tshuab! Tua ob tug noog nrog ib lub pob zeb (lossis ob lub yoov nrog ib lub swat, kom nres ob lub qhov ncauj nrog ib lub ncuav, kom ua ob tug phooj ywg nrog ib qho khoom plig, kom muaj ob txoj hlua rau ib rab hneev, lwm yam lus piv txwv txog qhov teeb meem - koj puas tau xav? Thov txim, Kuv digressed).

Tus txiv neej tus lej sib txawv yuav siv los txuas tus poj niam sib piv lub taub hau los ntawm veroboard nrog ESP32-Cam thiab lwm yam khoom siv.

Ob lub Cheeb Tsam tau txuas nrog tus choj 3d-luam ntawv, uas tseem muaj lub tsev hloov pauv thiab qhib lub zog.3d STL cov ntaub ntawv rau tus choj thiab lwm yam khoom nyob hauv cov ntawv/3d nplaub tshev ntawm GitHub.

Kauj ruam 4: Lub zog

Ntaj tau siv los ntawm 2500 mAh USB lub txhab nyiaj fais fab - qhov tsawg tshaj plaws thiab thim qhov kuv pom tau. Powerbank swb rau hauv 3d-luam ntawv rooj plaub, uas tseem txuas rau dot matrix modules, yog li tuav txhua yam ua ke.

Muaj ob lub hlau nplaum puag ncig rau ntawm lub txhab nyiaj fais fab, thiab yog li cas rab ntaj txuas rau lub qhov rooj (yog li nws tuaj yeem yooj yim cais rau kev saib xyuas).

Kauj ruam 5: Schematic

Cov txheej txheem tiag tiag nyob ntawm GitHub, tab sis daim duab muaj nqis 1000 lo lus (1024 hauv Cov Ntaub Ntawv Technology), yog li ntawm no koj yog:

Qhov no yog qhov ncaj ncaj yog tias koj paub koj txoj hauv kev nrog rab phom phom. NOV NCO NTSOOV: Qhov ntu 3d choj tau tsim los rau qhov tshwj xeeb tshwj xeeb veroboard loj: 30 x 70 hli. Koj yuav tsum txiav txim siab siv qhov sib txawv, koj yuav tsum rov tsim tus choj txuas.

Kauj Ruam 6: 3d Luam Ntawv

Cov roj teeb thiab tus choj txuas ESP32-CAM veroboard mus rau dot-matrix zaub sib dhos tau 3d tsim thiab luam tawm.

Cov roj teeb rooj tuaj nyob hauv 2 ntu, uas yuav tsum tau ua ke ua ke tom qab luam ntawv los tsim "hnab tshos" rau lub roj teeb. Tus choj tsuas yog yuav tsum tau ntxuav ntawm txhua qhov kev txhawb nqa (tsis muaj kev qhia zoo tiag tiag uas txo lawv, hmoov tsis zoo). STL cov ntaub ntawv nyob ntawm GitHub thiab TinkerCad cov hauv paus tseem nyob ntawm no.

Kev tsim 3D ntawm TinkerCad kuj suav nrog cov qauv sib dhos ua piv txwv ntawm yuav ua li cas ntu haum ua ke thiab yuav tsum txuas nrog.

Kauj ruam 7: Programming

Multi-multitasking

Qhov kev tsim no siv FreeRTOS rau kev npaj ua ntau yam ua ntej thiab TaskScheduler lub tsev qiv ntawv rau kev koom tes. Ntaj tus cwj pwm thiab cov lus raug tswj los ntawm Blynk App. Tom qab teeb tsa (pins, lub koob yees duab thiab dot-matrix pib, txuas rau WiFi, thiab lwm yam), ob lub ntsiab RTOS cov haujlwm tau tsim:

• Kev tshaj tawm video RTOS ua haujlwm, txuas rau Daim Ntawv Thov Tub Ntxhais ntawm ESP32 (core 1)
• Cov ntawv nyeem thiab Blynk tswj RTOS txoj haujlwm, txuas rau Lub Hwj Chim ntawm ESP32 (core 0), uas tseem yog lub luag haujlwm rau txhua yam haujlwm ntsig txog WiFi. Cov ntawv thiab Blynk ntsig txog kev ua tiav yog tswj hwm los ntawm TaskScheduler cov haujlwm.

Kuv pom tias 4K ntawm pawg chaw txaus rau RTOS cov haujlwm, tab sis muaj peev xwm khiav tawm ntawm pawg, yog li yog tias koj xav tau, ua rau nws 8K - muaj RAM ntau ntawm ESP32.

Txhua qhov vis dis aus ntes thiab tshaj tawm tau tshwm sim ntawm Core 1. Txhua yam ntxiv - ntawm Core 0.

ESP32 muaj lub zog txaus los daws txhua qhov ntawd nrog tsoo me ntsis hws (pawg thawj coj tau kub thaum tshaj tawm cov vis dis aus).

Qhov no yog lub hom phiaj tseem ceeb ntawm txoj haujlwm: muaj kev thaj yeeb nyab xeeb thiab muaj txiaj ntsig ntawm kev npaj ua ntej thiab koom tes ua haujlwm ntau yam!

Kauj Ruam 8: Dot Matrix Control

Kuv tab tom siv muaj zog heev MD_Parola thiab MD_MAX72xx cov tsev qiv ntawv kuj muaj nyob hauv Arduino IDE tus thawj tswj tsev qiv ntawv.

Txhua qhov tshwj xeeb cov ntawv tau ua tiav ntawm cov tsev qiv ntawv ntawd. Nws siv zog me ntsis los txiav txim siab qhov tseeb MAX72XX hom kho vajtse (MD_MAX72XX:: ICSTATION_HW hauv kuv qhov xwm txheej, koj li yuav txawv), tom qab ntawd, tswj cov ntawv yog cua.

Ntaj tso cai rau kev tswj hwm hauv qab no:

• Ci ntsa iab
• Tsaus muag
• Nyem
• Scroll ceev thiab kev taw qhia (nce/nqis, sab laug/sab xis, khov kho)
• Koj tseem tuaj yeem hloov nws mus rau hauv Lub Sijhawm Phab Ntsa

Kauj Ruam 9: Tshaj Tawm Video

Blynk App muaj cov cuab yeej me me los tso video, tab sis koj tuaj yeem nkag mus rau hauv qhov browser, VLC player, lossis txhua yam uas txhawb MJPEG tus qauv.

Txog li 10 tus neeg siv sib txuas tau txais kev txhawb nqa.

Koj yuav tsum nrhiav tus IP chaw nyob ntawm koj li ESP32-CAM kom tuaj yeem txuas rau nws. Koj tuaj yeem saib nws ntawm koj lub router, lossis suav qhov kos duab no nrog _DEBUG_ kev xaiv ua ntej, thiab nyeem tus IP chaw nyob ntawm lub davhlau ya nyob twg thaum nws txuas rau koj lub network.

TSEEM CEEB: Nws raug nquahu kom muab tus IP chaw nyob ruaj khov rau, lossis tsim DHCP qhov tshwj tseg rau, ESP32-CAM module yog li nws qhov chaw nyob tsis hloov pauv thaum daim ntawv cog lus tas sijhawm. Koj kuj tseem tuaj yeem hloov kho Blynk App txhawm rau hloov kho tus IP chaw nyob hauv kwj URL - qhov haujlwm ua haujlwm zoo yog tias koj ua tiav.

Cov duab kos tam sim no siv QVGA daws teeb meem: 320x240 pixels, uas ua rau nws nrawm heev. Koj muaj kev ywj pheej thiab txhawb kom ua si nrog lwm qhov kev txiav txim siab thiab txiav txim siab ua haujlwm dab tsi rau koj.

RAM yuav tsum tsis muaj teeb meem raws li cov duab kos ua kom zoo dua ntawm PSRAM.

Kauj ruam 10: Kev teeb tsa

Cov duab kos siv qhov zoo ntawm kuv phau ntawv txhais lus thiab EspBootstrap cov tsev qiv ntawv los thauj cov teeb tsa tsis los ntawm kev teeb tsa server thaum khau raj.

Kuv khiav kuv tus kheej teeb tsa server, uas koj tuaj yeem ua tau ib yam (nws yog Apache2 web server yooj yim tiag tiag tsuas yog ua haujlwm rau JSON cov ntaub ntawv).

Koj tseem tuaj yeem siv ib qho ntawm cov kev pabcuam online muaj rau txoj haujlwm: (OTADrive, Microsoft Azure, AWS IoT, thiab lwm yam). Hauv qhov xwm txheej no thov hloov Txoj Cai makeConfig (Txoj hlua txoj hauv kev) kom tsim nyog tsim URL taw tes rau koj qhov chaw teeb tsa. Xwb, koj tuaj yeem txuag cov ntaub ntawv teeb tsa mus rau hauv SPIFFS cov ntaub ntawv system ntawm ESP32-CAM thiab nyeem nws los ntawm qhov ntawd, lossis tsuas yog hardcode txhua qhov nkag. Thov saib README ntawm EspBootstrap lub tsev qiv ntawv rau koj cov kev xaiv.

Ib qho piv txwv ntawm cov ntaub ntawv teeb tsa tau muab rau ntawm GitHub.

Yog tias koj xav tau hardcode tsis, piv txwv yog hauv qab no:

pd ("Title", "DND Ntaj Teeb");

pd ("ssid", "koj li wifi ssid"); pd ("password", "koj tus password wifi"); pd ("msg", "Nyob zoo!"); pd ("khoom siv", "8"); pd ("blynk_auth", "koj blynk AUTH UUID"); // yog tias koj khiav koj tus kheej lub server nkaus xwb: pd ("blynk_host", "koj blynk server IP"); pd ("blynk_port", "koj qhov chaw nres nkoj server");

Kauj Ruam 11: Hloov Kho Firmware OTA

Cov duab kos tseem yog OTA (Dhau The Air) firmware hloov tshiab tau qhib thiab tab tom tshawb xyuas cov firmware tshiab ntawm txhua lub khau raj.

Ib zaug ntxiv, Kuv tau khiav kuv tus kheej OTA hloov tshiab server, uas koj tuaj yeem ua tau ib yam (nws yog qhov yooj yim Apache2 webserver nrog me ntsis ntawm PHP scripting ua haujlwm cov ntaub ntawv binary).

Koj tseem tuaj yeem siv ib qho ntawm IoT cov kev pabcuam online muaj rau txoj haujlwm: (OTADrive, Microsoft Azure, AWS IoT, thiab lwm yam). Hauv qhov no thov hloov pauv qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm teeb liab teeb liab teeb liab teeb liab teeb pom kev teeb tsa qhov teeb meem URL taw rau koj cov ntaub ntawv binary.

Qhov no yog nyob ntawm yeem - koj tuaj yeem xaiv tsuas yog upload binaries ntawm kev txuas txuas.

Kauj ruam 12: MJPEG Server

Cov ncauj lus no tau piav qhia ntxaws ntawm no.

Kauj ruam 13: Blynk App

Blynk yog huab-based IoT platform uas tso cai rau App txhim kho sai. Nws yog pub dawb rau siv tus kheej thiab txawm tias muaj kev xaiv khiav koj tus kheej Blynk server.

Kuv (raws li koj yuav tau kwv yees lawm) kuv tab tom khiav kuv tus kheej Blynk server, tab sis nws yuav yooj yim dua rau koj siv huab huab. Nruab Blynk iOS lossis Android App, thiab ua raws cov duab hauv qab no txhawm rau txhim kho App ntawm koj lub xov tooj.

Koj yuav tsum tau muab koj tus kheej Blynk Auth UUID rau daim ntawv thov ua haujlwm nrog koj App. Qhov no yog vim li cas kuv siv cov ntaub ntawv teeb tsa. Txawm li cas los xij, rau ib qhov haujlwm ib zaug, tus lej nyuaj yuav ua haujlwm zoo ib yam.

TSEEM CEEB: Thov nco ntsoov tias koj li Blynk Project tau teeb tsa los ceeb toom Cov Khoom Siv Thaum Txuas App.

LUS CEEB TOOM ntawm cov vis dis aus tso tawm suab: qee zaum cov vis dis aus tsis pib. Nws tsis zoo li muaj teeb meem nrog ESP32, theej nrog cov vis dis aus widget ntawm Blynk daim ntawv thov. Sim kaw thiab rov qhib App lossis nres/pib qhov haujlwm dua. Thaum kawg, nws pib. Qhov teeb meem no tsis zoo li muaj nyob hauv qhov browser lossis VLC player (piv txwv).

Kauj ruam 14: Txaus siab rau

Nws yog qhov lom zem heev tsim lub tsev no thiab ua pov thawj tias cov cuab yeej siv cim npe zoo li ESP32 tuaj yeem ua ntau ntau dua li tsuas yog kwj video. Ntau lub tswv yim los ntawm txoj haujlwm no tuaj yeem rov siv dua hauv lwm daim ntawv thov.
