Hloov kho 5 Lub Plaub Hlis 2021: kos duab tshiab thiab hloov kho rau cov khoom siv hluav taws xob. Qhov tshiab kos duab: command_station_wifi_dcc3_LMD18200_v4.ino

Hom DCC tshiab siv WiFi los sib txuas lus qhia 3 cov neeg siv xov tooj ntawm tes/ntsiav tshuaj tuaj yeem siv rau ntawm tus qauv zoo rau ob qho tib si hauv tsev thiab qws qauv kev tsheb ciav hlau

Ib qho yooj yim hluav taws xob hluav taws xob muab DCC teeb liab thiab lub zog rau txoj kev taug, txawm li cas los xij App ua haujlwm tiag tiag! Lub khoos phis tawj ntawm koj lub xov tooj tau siv tag nrho los ntawm kev tsim cov lej uas yuav tsum tau ua los ua txhua pob ntawv ntawm cov lus qhia, yog li ua kom yooj yim txoj haujlwm ntawm tus tswj hwm micro!

App muaj nyob ntawm £ 8.49 ntawm Play Store 'Locomotive DCC 3 WiFi'

- Cov App no yuav tsum tau teeb tsa hauv cov khoom siv nrog Android 7 nce mus.

Qhov yooj yim tshaj puas tau NMRA ua raws DCC Command chaw nres tsheb !! Saib cov npe ntawm cov yam ntxwv hauv qab no

Kauj Ruam 1: Nkag Siab Rau Hauv ESP32 Nta & Siv Nws Nrog Arduino IDE

Ob peb xyoos dhau los, ESP8266 coj lub ntiaj teb IoT los ntawm cua daj cua dub. Tsawg dua $ 3, koj tuaj yeem tau txais lub programmable, WiFi-enabled micro-controller muaj peev xwm saib xyuas thiab tswj hwm txhua yam los ntawm txhua qhov chaw hauv ntiaj teb. Tam sim no Espressif (Lub tuam txhab semiconductor tom qab ESP8266) tau tshaj tawm qhov kev hloov pauv zoo tshaj plaws: ESP32. Ua tus ua tiav rau ESP8266; tsis tsuas yog nws muaj kev txhawb nqa WiFi, tab sis nws tseem muaj Bluetooth 4.0 (BLE/Bluetooth Ntse) - zoo meej rau tsuas yog hais txog ib qhov haujlwm IoT.

ESP32 Sib Koom 802.11b/g/n HT40 Wi-Fi transceiver, yog li nws tuaj yeem tsis tsuas yog txuas rau WiFi network thiab cuam tshuam nrog Is Taws Nem, tab sis nws tseem tuaj yeem teeb tsa lub network ntawm nws tus kheej, tso cai rau lwm yam khoom siv txuas ncaj qha rau nws. ESP32 txhawb WiFi ncaj qha ib yam, uas yog qhov kev xaiv zoo rau cov phooj ywg-rau-phooj ywg kev sib txuas yam tsis xav tau lub nkag nkag. WiFi ncaj qha tau teeb tsa yooj yim dua thiab cov ntaub ntawv xa mus nrawm dua li Bluetooth. Qhov tseem muaj ob lub peev xwm Bluetooth muaj peev xwm, txhais tau tias nws txhawb nqa ob qho Bluetooth 4.0 (BLE/Bluetooth Smart) thiab Bluetooth Classic (BT), ua rau nws ntau dua ntau yam.

Hauv txoj haujlwm no, kuv tsuas yog siv lub peev xwm WiFi los tsim lub server hauv zos rau DCC qhov chaw nres tsheb kom sib txuas lus nrog Android App.

Hauv kev tshawb xav, nws muaj peev xwm tsuas yog siv ESP tus qauv, txawm li cas los xij lub moos tsim cov cai xav tau yog qhov sib txawv kiag li los ntawm AVR moos chaws siv hauv Arduino Pro Mini. Kuv tso txoj haujlwm no rau lwm tus nyeem ntawv nyob ntawd!

Kev sib txuas ntawm ESP32 thiab Arduino yog qhov yooj yim tiag tiag - saib daim duab kos duab. RX, TX los ntawm Pro Mini txuas rau Rx2, Tx2 ntawm ESP ntaus ntawv. Nco tseg kev siv cov tshuaj tiv thaiv kom nqis qis qib teeb liab mus rau ESP32 vim nws tsuas tuaj yeem siv qib 3.3v.

Kauj Ruam 2: Daim duab Circuit Court thiab PCB

Arduino Circuit yog tib yam uas tau siv hauv Bluetooth version. Kuv tau ntxiv cov qhov (socket) los teeb tsa ESP32 qhov chaw ntawm BT module. Tam sim no PCB tau muag rau ntawm eBay ntawm no. Qhov Arduino yuav tsum yog Pro Mini ATmega 328 16MHz 5v version

ESP32 ua raws li WiFi server, tau txais cov ntaub ntawv los ntawm WiFi_DCC App thiab xa qhov no mus rau Arduino ntawm TX2 tus pin. Txhua cov ntaub ntawv rov qab mus rau App yuav raug xa los ntawm tus pin RX2.

Qhov kev txiav txim siab tam sim no 0.1 ohm pom ntau tshaj thiab cov xwm txheej luv luv uas tom qab ntawd teeb tsa lub kaw lus kom txog thaum tau txais lub teeb liab pib dua.

LMD18200T h-choj hloov DCC pob ntawv rau hauv AC waveform uas muab cov khoom khiav nrog lub zog thiab cov ntaub ntawv.

Nco tseg: 5 tus tswj hluav taws xob hauv pob TO-220 tau kub thaum ua kom lub zog ESP32 (txog 200 mA) yog li ntawd yuav tsum siv lub rhaub dej kub.

Kho tshiab 17/7/2020 - thov siv daim duab tshiab txuas nrog 'DCC_WiFi_v2.ino'

Qhov kev kos duab no teeb tsa koj cov neeg rau zaub mov hauv zos thiab tau txais kev hloov tshiab los ntawm App ntawm koj lub cuab yeej hauv xov tooj.

Mus rau GitHub txuas kom tau txais cov ntaub ntawv xav tau ntawm no.

ESP32S yuav tsum tau programmed ntawm Arduino IDE. Mus rau Cov Cuab Yeej, Pawg Thawj Coj, thiab xaiv Node32S lossis NodeMCU-32S los ntawm cov npe.

Mus rau Cov Cuab Yeej, Chaw nres nkoj thiab xaiv /dev/cu. SLAB_USBtoUART

Qhov ntawd yog qhov kev xaiv ntawm kuv Apple MacBook Air - qee yam zoo sib xws hauv PC Kuv xav.

Arduino kos duab 'DCC_WiFi_v1.ino' xav tau cov ntaub ntawv hauv tsev qiv ntawv no:

// rau App 'LocoMotive WiFi Controller'

// tsim kom muaj WiFi nkag mus thiab muab lub web server rau nws

#suav nrog "WiFi.h" #suav nrog "WiFiClient.h" #suav nrog "WiFiAP.h"

const char *ssid = "DCC_WiFi"; // yuav tsum tau sib phim hauv Android cov cuab yeej teeb tsaconst char *password = "123456789"; // yuav tsum tau nkag mus thaum xaiv ssid saum toj no

WiFiServer server (80);

Hloov kho 24/3/2021 - thov siv daim duab tshiab txuas nrog 'command_station_wifi_dcc3_LMD18200_v3.ino'

Txhawm rau thauj cov duab kos rau Arduino Pro Mini koj xav tau USB- TTL adapter xws li CH340 muaj nyob ntawm eBay lossis ntawm no ntawm Hobby Components website:

Kauj Ruam 5: WiFi_DCC App

Lub App muaj nyob hauv Google Play Store ntawm no 'LocoMotive DCC 3 WiFi'.

Lub App muaj nyob hauv Google Play Store ntawm no 'LocoMotive DCC 2 WiFi'.

Lub App yuav raug thauj mus rau ntau dua ib lub cuab yeej Android txhawm rau muab ntau DCC lub qhov ncauj.

Nco tseg: App ua haujlwm tau zoo ntawm Android 7, txawm li cas los xij ntawm Android 9 nce koj yuav tsum hloov OFF 'mobile data' hauv xov tooj

Koj kuj tseem yuav tau hloov ON GPS hauv Qhov Chaw Teeb ntawm koj lub cuab yeej.

Tsis tas li, koj yuav tsum nyem qhov Tau Txais WiFi khawm ob peb zaug kom txuas tau zoo.
