Qhov qhib-ceeb toom API muaj peb yam uas tuaj yeem nthuav tawm, qhov chaw ntawm ISS hauv txoj kab nruab nrab thiab txoj kab nruab nrab, dhau qhov kev twv ua ntej raws qhov muab latitude thiab ntev. Thiab thaum kawg pes tsawg tus neeg (Thiab lawv lub npe) nyob hauv qhov chaw.

Peb yuav tau teeb tsa lwm lub tsev qiv ntawv - Lub tsev qiv ntawv ArduinoJson.

github.com/bblanchon/ArduinoJson

Peb kuj xav tau TimeLib.h tab sis kuv tsis paub meej tias kuv tau txais qhov ntawd los ntawm lossis yog tias nws suav nrog hauv IDE (thov txim)….

Yog li vim li cas thiaj kwv yees tias ISS yuav nyob qhov twg - ISS muaj ntau yam khoom siv xov tooj cua nyiam, thiab thaum nws "hla lub taub hau" tus xov tooj cua ham tuaj yeem sib cuag nrog ISS siv qee lub xov tooj cua yooj yim heev (thiab pheej yig). Kuv tseem tau ua nws thaum mobile (tsav tsheb). Koj yeej tsis xav tau ntau los ua txoj haujlwm no. Ib yam uas koj xav tau yog paub tias nws nyob qhov twg. Thiab taw tes tus kav hlau txais xov hauv nws txoj kev qhia dav dav pab.

Kab 57, 58, 59 yog qee qhov hloov pauv zaub - yog tias lawv tau teeb tsa rau 1 koj yuav pom cov zaub, yog tias lawv tau teeb tsa rau 0 (xoom) koj yuav tsis pom cov zaub. (Cov kev hloov pauv no tuaj yeem teeb tsa hauv qhov kos duab, lossis hloov kho los ntawm lub vev xaib uas lub foob pob hluav taws tsim - ntau ntxiv tom qab ntawd).

int locDis = 1; // Zaub Qhov Chaw ntawm ISSint pasDis = 0; // Zaub Pass Predictions int pplDis = 1; // Tso cov neeg hauv Chaw

yog li locDis yuav nthuav qhia qhov chaw ntawm ISS hauv latitude thiab longitude - nws kuj tseem qhia tau pes tsawg mais deb nws yog.

pasDis yuav tau txais qhov kev kwv yees dhau los ntawm open-notify.org thiab tso tawm rau lawv.

thiab thaum kawg, pplDis yuav tso saib cov npe thiab pes tsawg tus neeg nyob hauv qhov chaw - qhov no tuaj yeem tau ntev heev, nws tsis yog

hloov pauv ib yam nkaus. (koj tuaj yeem hloov cov no lossis tso tseg, nws yog qhov kev xaiv tag nrho)

Peb kuj yuav tsum paub peb qhov latitude thiab longitude thiab muab tso rau hauv daim duab.

Qhov no tsis tas yuav yog qhov tseeb lat/ntev, nws tuaj yeem yog qhov chaw nruab nrab ntawm koj lub nroog, lossis tawm me ntsis. Kev taw ntawm ISS yog dav thaum nws hla lub taub hau, thiab ntau pua (lossis ntau txhiab) mais tuaj yeem npog tau, yog li tawm me ntsis ntawm koj qhov lat/ntev yuav tsis yog qhov cuam tshuam cuam tshuam (feem ntau ntawm lub sijhawm), kev sib txuas lus dhau 500 mais yog qhov zoo nkauj heev.

Yog tias koj tsis paub koj qhov latitude thiab longitude lub vev xaib no tuaj yeem pab koj tawm.

www.latlong.net Nyob ze kab 84 ntawm qhov kos duab koj yuav pom qee yam zoo li no:

// Nrhiav koj lub Latitude thiab Longitude ntawm no // https://www.latlong.net/ float mylat = 39.360095; ntab mylon = -84.58558;

Qhov ntawd yuav tsum yog txhua yam uas yuav tsum tau hloov pauv. Muab cov duab kos, thiab txuas rau Firebeetle rau hauv internet - thiab koj yuav tsum pom, qhov chaw ntawm ISS muab rau hauv lat/ntev thiab pes tsawg mais deb nws yog (nco ntsoov qhov no yuav yog kwv yees li deb. ISS txav nrawm heev, thiab los ntawm lub sijhawm cov zaub tiav ISS tau txav deb ntau mais los ntawm qhov nws nyob). Koj yuav tsum pom cov neeg nyob hauv qhov chaw. (Yog tias koj tsis hloov pauv qhov sib txawv saum toj no).

Peb tab tom siv tus tub ntxhais thib ob ntawm ESP32 los khiav lub vev xaib, siv lub xaib muab peb tswj hwm yam uas tau tshwm ntawm LED matrix. Nws yuav tsum nkag siab zoo txog qhov nws ua haujlwm li cas, ib ntu qhia qhov qhib rau zaub, lwm ntu muaj "yog" "tsis yog" cov nyees khawm - nyem "yog" txhais tau tias koj xav pom nws, "tsis" txhais tau tias tsis t qhia nws. Koj kuj yuav tsum pom tias ntu ntu hloov pauv raws li cov nyees khawm.

Qhov tsuas yog qhov uas tsis yog txiav thiab qhuav ntawm no yog yuav ua li cas thiaj nrhiav tau tus IP chaw nyob ntawm Firebeetle - hmoov tsis kuv tsis tuaj yeem muaj txoj hauv kev zoo los nrhiav nws - yog li kuv tsuas yog siv cov ntawv txuas ntawm IDE los tso saib nws (9600 baud).

Qhib lub console, thiab koj yuav tsum pom tus IP chaw nyob. (qhib nws ua ntej koj tau txais cov lus txuas) - kuv lwm qhov kev xaiv yog los tso nws ntawm LED Matrix ib zaug thaum pib - Kuv txiav txim siab tawm tsam qhov ntawd vim tias koj yuav tsis saib lub sijhawm thiab koj yuav nco nws. Kuv tau txiav txim siab xa xov sms, lossis qee yam tab sis, thaum kawg kuv tsuas yog ua kom yooj yim. (Kuv kuj tau sim muab tus IP zoo li qub/rooj vag/lwm yam, Kuv tsis tuaj yeem ua nws txoj haujlwm nrog tus thawj tswj hwm wifi - tus lej tseem nyob hauv daim duab, yog li yog ib tus neeg suav nws tawm qhia rau kuv paub)

Cov duab kos tseem yuav siv ua ntej ntawm FreeRTOS tsim rau hauv ESP32 core - Peb muaj lub luag haujlwm uas ua haujlwm txhua 15 feeb lossis yog li, qhov no ua li cas yog hloov kho qhov kev twv ua ntej dhau los, nrog rau cov neeg nyob hauv qhov chaw. Zoo li kuv tau hais ua ntej cov neeg hauv qhov chaw tsis hloov pauv ntau, yog li ntawd tej zaum yuav raug hloov mus rau lwm txoj haujlwm thiab tej zaum tau khiav ib zaug txhua 12 teev (lossis 6 teev) - tab sis qhov no ua haujlwm, thiab nws ua kom yooj yim.

Rau cov uas tsis paub FreeRTOS yog ib txoj hauv kev cia ib leeg tub ntxhais micro-maub los ua haujlwm ntau ntxiv

Feem ntau koj yuav tsum suav nrog qee lub tsev qiv ntawv thiab lwm yam los ua kom nws ua haujlwm - txawm li cas los nws tau tsim rau hauv cov tub ntxhais rau ESP32 - uas ua rau ESP32 muaj zog heev. yog xav paub ntxiv txog FreeRTOS

freertos.org/

Hloov kho: muaj ntau yam uas tuaj yeem txhim kho rau txoj haujlwm no, thiab yuav luag txhua hnub kuv xav txog qee yam uas tuaj yeem ua tau txawv me ntsis, lossis hloov pauv, lossis ntxiv.

Thiab hauv ntau qhov piv txwv cov npe ntawm cov chaw cia khoom koj tuaj yeem pom qee qhov ua ntej/txawv qhov kuv xav txog- qee qhov no tsis ua haujlwm, qee qhov tsuas yog hloov pauv, thiab qee qhov uas suav nrog hauv daim duab tam sim no.

* Ntawm ib kis kuv tau sim ntxiv neopixel rau cov zaub yog li nws yuav zoo li me ntsis zoo li kuv txoj haujlwm yav dhau los - Kuv yeej tsis tau txais nws ua haujlwm tau zoo (Kuv pom nws yog qhov teeb meem lub zog uas kuv tsis tau txiav txim siab) Kuv yog ua haujlwm ntawm txoj hauv kev los txhim kho lub tswv yim no *

Thaum sau cov theem no, kuv xav tias, tej zaum kuv tuaj yeem ntxiv txoj hauv kev hloov kho koj qhov latitude thiab longitude mus rau lub vev xaib - txoj kev kos duab yuav tsis tas yuav hloov kho - Kuv yuav xav txog qhov no me ntsis ntxiv thiab.

Ib txoj hauv kev txhim kho kom tau txais IP chaw nyob yog lwm yam kuv xav ua (tseem xav txog qhov ntawd ib yam nkaus)

Cia peb txav mus rau peb qhov haujlwm tom ntej ….

Kauj Ruam 7: Txoj Haujlwm 3: Yooj Yim Tsiv Mus Sau Npe Siv MQTT

"chaw thau khoom =" tub nkeeg "" chaw thau khoom = "tub nkeeg"

Yog li nws hloov tawm, tias lub tsev qiv ntawv tuaj yeem tso saib cov duab - koj rau qee qhov laj thawj uas ua haujlwm zoo li "ntiag tug" - zoo, rau cov duab kos tom ntej no kuv hloov lub tsev qiv ntawv ib zaug ntxiv thiab ua kos duab duab ua haujlwm rau pej xeem.

Lub sijhawm no, Kuv muab cov tsev qiv ntawv hloov pauv hauv cov kab kos duab, yog li koj tsis tas yuav rov nruab lub tsev qiv ntawv, kos duab saib ntawm nws tus kheej ua ntej, tom qab ntawd nws yuav saib hauv phau ntawv teev npe, yog li peb zoo!

*** Kuv tab tom npaj yuav xa qhov kev hloov pauv no mus rau DFRobot, vim nws yog qhov txias heev, thiab ua kom zoo kom muaj peev xwm ua tau cov duab zoo li no ***

LED Matrix Cov duab kos, ntawm no kuv tau xub sim los xyuas seb lub tsev qiv ntawv xav tau dab tsi, thiab dab tsi yuav thiab yuav tsis ua haujlwm - nrog kev sib txawv ntawm kev ua tiav. Kuv pom tias 8x8 cov duab ua haujlwm zoo tshaj plaws, tab sis koj tuaj yeem tau txais lwm tus los ua haujlwm ib yam. Kuv pom ob peb online coj tus kws kho qhov muag hauv online ib yam, qee qhov ua haujlwm zoo dua li lwm tus.

xantorohara.github.io/led-matrix-editor/-zoo li ua haujlwm tau zoo, ua 8x8 cov duab, thiab koj xav kom lawv ua byte arrays.

www.riyas.org/2013/12/online-led-matrix-fo… qhov no ua haujlwm tau zoo, thiab muaj peev xwm ua kom loj dua 8x8 cov lus qhia, cov zaub zoo li tig rau nws ib sab nrog cov zaub no txawm li cas los Byte arrays zoo li ua haujlwm zoo tshaj plaws ntawm no. Kuv siv nws los ua "qhov chaw nkag" pom hauv cov vis dis aus saum toj no.

Yog li qhov no ua haujlwm li cas, drawImage (const byte * img, uint8_t width_t, uint8_t height_t, int8_t x, int8_t y, int img_offset);

duab byte array sib txawv, qhov dav ntawm daim duab (8), qhov siab ntawm daim duab (8), txoj haujlwm pib ntawm qhov screen x (0), y (0) feem ntau, thiab tus lej offset, uas kuv tsis yog 100% paub tseeb tias nws ua dab tsi, yog li feem ntau kuv tso nws ntawm xoom.

Hauv qhov kos duab LED Matrix Cov Duab - muaj 8 qhov sib txawv byte arrays - nrog peb txoj kev sib txawv ib yam nkaus.

- foob pob hluav taws yog thawj pawg, ua siab ncaj Kuv tsis paub tseeb tias qhov no ua haujlwm li cas - tab sis nws ua haujlwm.

tom ntej no muaj lub qhov ncauj - qhov no tsis ua haujlwm zoo tiag tiag, lub qhov ncauj tso qhov tsis raug rau ib tus, thiab sim ua qhov hloov pauv tsuas yog ua rau nws tsis zoo. (kawm paub dab tsi ua haujlwm thiab dab tsi tsis yog ib nrab ntawm kev lom zem)

Ua raws los ntawm thawj marioImg - qhov no loj dhau rau cov zaub, thiab kuv xav tias qhov no yog qhov chaw teeb tawm los ua si - Kuv tau siv nws ntawm no, thiab koj tuaj yeem pom pem hauv ntej ntawm mario, yog tias koj hloov qhov offset rau 1 koj ' yuav pom nws nraub qaum. (koj kuv tsis tuaj yeem qhia koj yog vim li cas lossis qhov offset ua dab tsi. Nws zoo li hloov cov duab tab sis vim li cas 2 hloov nws kom koj tuaj yeem pom ntawm nws xub ntiag thiab yog vim li cas 1 hloov lwm txoj kev kuv tsis tuaj yeem qhia koj)

IMAGES - byte array yog @ kos npe uas kuv tau ua - nws zoo li kuv tau siv lub cuab yeej ntawm

pic1 byte array kuj zoo li qhov kuv tau sim ua, tsuas yog nws me dua qhov kuv tau sim - nws yog dab tsi kuv tsis tuaj yeem hais, tab sis kuv tuaj yeem hais feem ntau nws zoo li kuv tau ua dab tsi hauv tus editor.

mario2Img - qhov no yog kuv tus kheej qhov loj ntawm Mario ua rau 8x8 npo loj - thiab koj muaj ib lossis ob lub pixels tawm ntawm qhov chaw (kuv ua txhaum, tsis yog cov lus qhia) nws zoo li me me Mario (sorta).

invader1 thiab invader2 - ob qho tib si kuv lub tswv yim rau qhov chaw invader. lawv tau ua tiav zoo nkauj, thiab los ntawm kev tso cov duab nyob rau sab saum toj ntawm txhua lwm yam, Kuv tuaj yeem tsim cov nyhuv ntawm taw txav.

Muaj ob daim duab kos duab foob pob hluav taws hauv cov npe, txhua qhov sib txawv me ntsis, thiab tsim nyog sim.

Ib qho muaj lub foob pob hluav taws txav hla lub vijtsam, yog li me ntsis ntxiv/txawv cov duab … lwm qhov muaj ob lub foob pob hluav taws tso tawm tib lub sijhawm

Kuj tseem muaj peb daim duab "ntxeem tau", txhua tus sib txawv me ntsis, ib tus muaj tus neeg txav mus hla lub vijtsam, thiab koj tuaj yeem saib seb kuv tau ua li cas - (muaj tej zaum yuav zoo dua ua nws, Kuv tsis paub)

Txawm Ntau: Muaj qee qhov kev kos duab hauv cov ntawv xeem ntawm lub chaw cia khoom - feem ntau ntawm cov no tsis ua haujlwm zoo li kuv xav, lossis yog cov tswv yim uas kuv xav ua, tab sis tsis ua haujlwm raws li kuv xav tau. Kuv tau tso lawv tseg vim tias qee tus neeg kuv tau txais qee lub tswv yim *(Kuv tau ua "daim thaiv" me me nrog WS2812 pixel rau nws siv nrog ISS zaub, tab sis kuv txuas nws mus rau 3v kab, thiab tsuas yog tsis muaj txaus lub zog nrog LED Matrix ua haujlwm ib yam, pixel ua haujlwm tau zoo, tsis muaj LED Matrix koj, yog li tseem muaj qee yam uas kuv yuav ua nrog nws)*

Kuj tseem muaj cov npe hu ua "Piv Txwv Ntxiv" - cov no yog kev hloov pauv ntawm qee qhov kev kos duab ntawm qhov haujlwm, txawm yog kuv tau ntxiv lossis tshem tawm, lossis hloov qee yam. Rau cov no, lawv ua haujlwm - lawv tsuas yog tsis yog qhov haujlwm kawg. Yog li kuv tso lawv tseg dua ib tus neeg yuav tau txais qee yam muaj txiaj ntsig zoo rau lawv. (Tej zaum)

Kuv vam tias koj nyiam qhov kev qhia no ntau npaum li kuv nyiam ua cov haujlwm no:-)

Kauj ruam 11: LInks…
