2 x 19 tus lej pin header (yog tias tsim nyog)

1 x PCB lossis Perfboard

1 x 3.3 V fais fab mov

Kauj Ruam 1: Rhuav Peb Lub Rooj INA

Thawj kauj ruam yog sib sau ua ke peb pawg INA260.

Cov lus qhia zoo heev tuaj yeem nrhiav tau ntawm Adafruit lub vev xaib. Ua raws li Adafruit cov lus qhia sib dhos.

Yuav kom tuaj yeem teeb lawv nyob rau ib sab ntawm ib sab siv tus pin ntev lub taub hau ntau dua li xa cov kab xev!

Kauj Ruam 2: Kho Peb Qhov Chaw Sib Txawv I2C

I2C yog cov txheej txheem sib txuas rau ob-xaim sib txuas los txuas cov cuab yeej siv qis dua qhov nyob deb. Ib tus tuaj yeem txuas mus txog 127 tus qhev. Ntawm ib lub tsheb npav txhua lub cuab yeej xav tau los ntawm tus cim I2C chaw nyob. I2C qhov chaw nyob ntawm lub cuab yeej feem ntau nyuaj siv rau hauv lub nti ntawm lub cuab yeej. Txhawm rau txuas tib lub cuab yeej ntawm ib lub npav, cov chaw tsim khoom feem ntau tawm qhov muaj peev xwm hloov pauv I2C chaw nyob los ntawm kev teeb tsa tus qauv ntawm tus pin ua ke.

Qhov no kuj yog rooj plaub rau peb pawg INA260. Cov cuab yeej muaj ob tus lej chaw nyob, A0 thiab A1 uas tuaj yeem txuas nrog GND, VS, SCL lossis SDA los teeb tsa qhov chaw nyob uas xav tau. Hauv cov ntaub ntawv ntawm INA260 nti los ntawm cov cuab yeej texas, ib tus tuaj yeem pom cov npe ntawm tus pin txuas rau txhua ntawm 16 qhov chaw nyob tau.

Pawg adafruit txwv qhov no rau 4 pawg los ntawm kev nthuav tawm ob daim ntaub uas tuaj yeem siv los rub A0 thiab/lossis A1 rau VS. Qhov chaw nyob tsis raug ntawm INA260 pawg thawj coj yog 0x40.

Koj ua tiav cov theem no los ntawm kev muab chaw nyob sib txawv rau ob lub rooj sib tham:

Los ntawm kev siv A0 ncoo ntawm pawg thawj coj thib ob koj teeb nws qhov chaw nyob rau: 0x41 (lossis 1000001 BIN)

Los ntawm kev siv A1 ncoo ntawm pawg thawj coj thib peb koj muab qhov chaw nyob rau: 0x44 (lossis 1000100 BIN)

Kauj Ruam 3: Txuas Ina Boards rau ESP32

Tam sim no peb tau muab cov chaw sib txawv I2C rau txhua ntawm INA cov laug cam, nws yog lub sijhawm los txuas lawv rau ESP32 pawg thawj coj saib!

Ib daim duab saum toj no, txuas

1) tus pin VCC rau tus pin 3.3V

2) tus pin GND rau tus pin GND

3) SDA tus pin rau GPIO tus pin 21

4) SCL tus pin rau GPIO tus pin 22

Kuv tau siv PCB tsim los ua kev sib txuas vim nws yog ib feem ntawm txoj haujlwm loj dua (WiFi hloov pauv qhov hluav taws xob nrog kev hloov kho tam sim no txwv - vam tias yuav ua tus qhia rau qhov no ib yam nkaus).

Koj tuaj yeem siv lwm txoj hauv kev rau kev sib txuas, qhov no yuav yog daim txiag ntoo uas koj tau siv lawm lossis siv lub khob cij. Ob leeg yuav ua haujlwm zoo ib yam.

Kauj Ruam 4: Nruab ESP32 Board hauv Arduino IDE

Tam sim no peb tau txuas cov laug cam rau ib leeg, nws yog lub sijhawm los tshuaj xyuas qhov txuas.

Peb yuav ua qhov ntawd los ntawm kev sau cov I2C chaw nyob ntawm Ina cov laug cam.

Pawg ESP32 ua haujlwm zoo nrog Arduino IDE.

Yog li cia peb teeb tsa ESP32 pawg thawj coj hauv Arduino siv Tus Thawj Saib Xyuas Haujlwm.

Kauj Ruam 5: Txheeb xyuas Ina rau ESP32 Kev Sib Txuas Siv I2C Scanner

Peb yuav siv qhov yooj yim I2C chaw nyob scanner kom ntseeg tau kev sib txuas ntawm ESP32 thiab Ina260 cov laug cam.

Kauj Ruam 6: Tsim HTML Lub Vev Xaib Lub Vev Xaib

ESP32 muab qhov ua tau rau khiav lub vev xaib. Nws kuj tseem muab lub cim xeeb RAM loj heev los tuav qee lub vev xaib. (Nws automaticlly compresses cov nplooj ntawv webpage).

Arduino IDE muab kev ua haujlwm rau upload cov vev xaib tsim mus rau ESP32's RAM ncaj qha.

Txhawm rau ua qhov no, koj yuav tsum tsim daim nplaub tshev 'cov ntaub ntawv' hauv qab Arduino qhov project daim nplaub tshev. Hauv kuv qhov no yog / Arduino / esp32_Power_supply_v1_implemented / data.

Nws yog ib qho tseem ceeb rau npe cov ntaub ntawv raws nraim 'cov ntaub ntawv' raws li nws yog lub npe nplaub tshev Arduino yuav saib thaum rub cov vev xaib nplooj ntawv mus rau ESP.

Kauj Ruam 7: Tsim Lub Hwj Chim Saib Xyuas Lub Vev Xaib

HMTL yog hom lus uas tso cai nthuav tawm cov ntawv rau hauv webbrowser. Cov ntaub ntawv HTML raug khaws tseg hauv qab txuas ntxiv htm (l). Kev tsim cov vev xaib feem ntau muab tso rau hauv cov ntawv cais (piv txwv li. Css file). Qhov haujlwm ua haujlwm uas lub vev xaib xav tau muab yog ib txwm muab tso rau hauv lwm cov ntawv (piv txwv li. Js file, rau javascript).

Hauv kuv cov ntawv HTML Kuv suav nrog cov ntawv, kev tsim thiab Javascript rau hauv ib daim ntawv. Yog li ntawd nws tsis yog ib qho piv txwv zoo ntawm yuav ua li cas rau lub vev xaib tab sis nws ua haujlwm lub hom phiaj. Kuv lub npe HTML daim ntawv 'Index.htm'.

Ib daim ntawv thib ob suav nrog hauv kuv cov ntaub ntawv khaws cia, piv txwv li. PicoGraph.js Lub tsev qiv ntawv PicoGraph tau muab los ntawm Vishnu Shankar B los ntawm RainingComputers thiab tso cai rau kev yooj yim heev, tseem muaj txiaj ntsig thiab hloov tau txoj hauv kev los nthuav qhia cov duab rau hauv lub vev xaib. Kuv hloov kho me ntsis cov cai kom pab tau kuv lub hom phiaj zoo dua.

Koj yuav pom tias HTML lub vev xaib tseem suav nrog cov cai tswj hwm cov khoom siv hluav taws xob ntawm kuv lub rooj tsav xwm PCB. Txoj cai muab hluav taws xob tswj hwm qhov ntsuas hluav taws xob ntawm 5 I/O pins. Koj tuaj yeem hloov txoj cai kom tshem tawm qhov no lossis koj tuaj yeem tso nws tawm yog tias tsis muaj kev cuam tshuam.

Cov cai html tau txuas rau cov kauj ruam no raws li txt cov ntaub ntawv (raws li cov lus qhia tsis tso cai rub tawm cov cai htm).

Txhawm rau siv tus lej HTML koj theej thiab muab nws tso rau hauv cov ntawv hloov kho (Kuv siv Notepad ++) thiab khaws nws li 'Index.htm' hauv qab 'Cov ntaub ntawv' nplaub tshev. Koj ua tib yam rau daim ntawv picograph.txt tab sis hloov nws mus rau picograph.js

Hais txog cov ntaub ntawv HTML:

Lub luag haujlwm SndUpdate yog siv los xa xov rov qab thiab xa mus los ntawm ESP mus rau lub vev xaib.

Cov lus xa los ntawm ESP tau ua haujlwm pabcuam lub zog thiab tsis muaj peev xwm ua tau rau cov lus qhia no. cov lus rau ESP tau ua haujlwm rau Ina260 pawg tswj hwm ntsuas.

var Msg = JSON.parse (xh.responseText); PG1_yrand0 = Msg. PG1_yrand0; PG2_yrand0 = Msg. PG2_yrand0; PG3_yrand0 = Msg. PG3_yrand0; PG4_yrand0 = Msg. PG4_yrand0; PG5_yrand0 = Msg. PG5_yrand0; PG6_yrand0 = Msg. PG6_yrand0;

Cov cai saum toj no nyeem 6 tus lej los ntawm ESP32 pawg thawj coj, piv txwv li. ntsuas qhov ntsuas hluav taws xob, ntsuas tam sim no los ntawm thawj pawg thawj coj, ua raws ob qhov ntsuas los ntawm qhov thib ob thiab lwm yam.

Cov kab ntawv tau kos rau hauv lub npe hu ua flex-ntim, uas tso cai rau hloov pauv qhov loj me ntawm lub vev xaib.

.flex-container {display: flex; xim tom qab: cadetblue; flex-qhwv: qhwv; }.flex-container> div {keeb kwm yav dhau xim: #f1f1f1; paj: 10px; duav: 20px; font-loj: 20px; font-family: "Xya Ntu"; font-ceeb thawj: siab tawv; }

Cov ntsiab lus ntawm txhua lub thawv hloov pauv tau ua raws li hauv qab no, suav nrog cov duab kos.

(nco ntsoov tias qhov twg raug tshem tawm)

div daim ntawv lo rau = "PG1_scale" Nplai:/daim ntawv lo lub npe = "PG1_scale" tus nqi = "10" brbr!-Canvas rau thr graph-canvas style = "height: 100px; ciam teb: 2px solid #000000; background-color: #fafafa; "Peb /ntaub
