Taw qhia

ESP32 yog tus nqi qis dual processor, nrog txhawb rau WiFi, Bluetooth Classic thiab BLE (Bluetooth Tsawg Zog). Txawm hais tias lub nti tau tawm rau ntau xyoo, kev txhawb nqa code rau Arduino tseem tsis tiav (raws li thaum lub Plaub Hlis 2018), tab sis cov lus qhia no thiab tus lej tsim hluav taws xob ua tiav hauv BLE uas ploj lawm thiab cov haujlwm sib piv sau.

Tswv yim: ESP32 tsis muaj 'standard Arduino' analogWrite muaj nuj nqi. Txawm li cas los xij tus lej tsim hluav taws xob no, tsim cov cai uas sim nws rau koj

Tswv yim: ESP code teeb tsa tsis suav nrog BLE kev txhawb nqa. Kev teeb tsa piav qhia ntawm no suav nrog kev txhawb nqa BLE

Nplooj ntawv web no yuav npog kev teeb tsa Arduino IDE los teeb tsa ESP32 rau BLE, Bluetooth lossis WiFi txuas. PfodDesigner tsim cov cai rau txhua qhov ntawm cov kev sib txuas no thiab tseem tsim cov cai los sim qhov ua tsis tau zoo analogWrite.

ESP32 yog tus nqi qis dual processor, nrog txhawb rau WiFi, Bluetooth Classic thiab BLE (Bluetooth Tsawg Zog). Txawm hais tias lub nti tau tawm rau ntau xyoo, kev txhawb nqa rau Arduino tseem tsis tiav (raws li thaum lub Plaub Hlis 2018), tab sis qhov kev qhia no thiab tus lej tsim hluav taws xob ua tiav hauv BLE uas ploj lawm thiab analogWrite ua haujlwm. Arduino IDE los teeb tsa ESP32 rau BLE, Bluetooth lossis WiFi txuas. PfodDesigner tsim cov cai rau txhua qhov ntawm cov kev sib txuas no thiab tseem tsim cov cai los sim qhov ua tsis tau zoo analogWrite.

Arduino ntxiv-ntxiv txhawb qee 31 ESP32 cov laug cam. Thaum siv pfodDesigner, koj yuav xav xaiv tus pin txuas uas phim cov uas muaj nyob ntawm koj lub rooj tshwj xeeb. Sparkfun ESP32 Yam (lossis Adafruit HUZZAH32 Feather) tau siv ntawm no ua piv txwv ESP32 pawg thawj coj, tab sis koj tuaj yeem siv tus lej rau ib qho ntawm 31 pawg ESP32 txhawb nqa.

Dawb pfodDesignerV3 Android app yog siv los tsim cov ntawv qhia zaub mov tswj (WYSIWYG) thiab tom qab ntawd tsim cov cai rau ESP32, rau BLE, WiFi lossis Bluetooth txuas. Thaum tau teeb tsa koj li ESP32 pawg thawj coj saib koj tuaj yeem siv pfodApp Android app (them nyiaj) los txuas rau koj ESP32 (ntawm BLE lossis WiFi lossis Bluetooth) thiab tso saib koj cov ntawv qhia zaub mov thiab tswj koj li ESP32. Yog tias koj tsis xav siv pfodApp, koj tseem tuaj yeem siv cov cim tsim los ua lub hauv paus rau koj tus kheej WiFi, BLE (Nordic UART) lossis Bluetooth sib txuas raws li nws muab kwj (luam/nyeem) interface rau txhua hom kev sib txuas no.

Kauj Ruam 1: Ntsis: Txhim Kho Kev Txhawb Arduino rau ESP32 Nrog Kev Txhawb BLE

Raws li thaum lub Plaub Hlis 2018, kev txhim kho Arduino ESP32 kev txhawb nqa yog kev koom tes ntau dua rau feem ntau lwm cov laug cam thiab cov tsev qiv ntawv cov cai nkag mus tsis tiav. Koj tsis tuaj yeem siv Arduino Board tus thawj coj los teeb tsa ESP32 kev txhawb nqa. Ua raws cov theem no txhawm rau teeb tsa Arduino rau ESP32 lub cajmeem. Qhov no yuav teeb tsa ESP32 thiab tseem txhawb nqa BLE.

1 Nrhiav txoj hauv kev ntawm koj li Arduino Sketchbook qhov chaw nyob Cov npe. Qhib Arduino IDE thiab saib hauv File-> Preferences thiab nyob rau sab saum toj ntawm lub vijtsam koj yuav pom Sketchbook qhov chaw.

2 Rub tawm ESP32_hardware.zip cov ntaub ntawv no thiab unzip nws mus rau Sketchbook qhov chaw. Nws tsim kho cov npe khoom kho vajtse nyob ntawd. Hauv qhov xwm txheej tsis zoo uas koj twb muaj cov npe khoom kho vajtse hauv koj qhov Sketchbook qhov chaw, sib koom nws cov ntsiab lus nrog qhov no.

3 Nruab Xtensa thiab ESP32 Cov Cuab Yeej. Nco tseg: Qhov rub tawm no thiab teeb tsa yuav siv qee lub sijhawm los ua haujlwm ~ 0.5Gig ntawm cov ntaub ntawv. Mus rau kho vajtse / espressif / esp32 / cov cuab yeej teev tom qab ntawd Rau Windows cov tshuab khiav cov ntawv get.exe. Rau Mac thiab Linux cov neeg siv, khiav cov ntawv get.py nab hab sej los rub tawm cov cuab yeej. Siv lub davhlau ya nyob twg, txav mus rau kho vajtse/espressif/esp32/cov ntawv tais ceev tseg. Tom qab ntawv ntaus: nab nab get.py Cov ntawv “get.py” nab hab sej yuav rub tawm Xtensa GNU cov cuab yeej thiab ESP32 software txhim kho cov khoom siv (SDK), thiab unzip lawv mus rau qhov chaw raug.

Koj yuav tsum pom ob peb daim ntawv tshiab hauv "cov cuab yeej" cov npe, suav nrog "sdk" thiab "xtensa-esp32-elf" thaum nws ua tiav.

Thaum qhov no ua tiav, kaw thiab rov qhib koj Arduino IDE thiab tam sim no koj yuav tsum muaj daim ntawv teev npe ntev ntawm ESP32 cov laug cam los xaiv los ntawm hauv Tool-> Boards menu. Xaiv "SparkFun ESP32 Yam" (lossis "Adafruit ESP32 Feather")

Tom qab ntawv koj tuaj yeem qhib Cov Ntaub Ntawv Piv Txwv kom pom tus lej ESP32 piv txwv cov ntaub ntawv

Cov txheej txheem saum toj no teeb tsa lub snapshot ntawm tus lej github rau ESP32 thiab BLE kev txhawb nqa uas tau koom ua ke rau hauv ib daim ntawv zip. PfodDesigner tsim cov cai thiab cov piv txwv hauv qab no siv cov ntawv no ntawm cov tsev qiv ntawv no. Yog tias koj xav tau qhov hloov tshiab kawg, nrog rau qhov muaj peev xwm sib txawv ntawm cov yam ntxwv thiab kab, tom qab ntawd rub lub zip ntawm qhov hloov tshiab kawg ntawm https://github.com/espressif/arduino-esp32 thiab unzip nws rau hardware/espressif thiab hloov npe nplaub tshev esp32 thiab tom qab ntawd rau BLE txhawb nqa rub tawm zip ntawm qhov hloov tshiab kawg ntawm https://github.com/espressif/arduino-esp32 thiab unzip nws mus rau esp32/cov tsev qiv ntawv thiab hloov nws ESP32_BLE_Arduino (yog tias tsim nyog).

Kauj Ruam 2: Txhim Kho PfodParser Libraries rau ESP32

a) Tom qab ntawd rub tawm pfodParser.zip lub tsev qiv ntawv V3.23+, pfodDwgControls.zip thiab, rau ESP32 WiFi, pfodESP32BufferedClient.zip, zip cov ntaub ntawv rau koj lub khoos phis tawj, txav lawv mus rau koj lub desktop lossis qee lwm daim nplaub tshev uas koj tuaj yeem nrhiav tau yooj yim.

b) Tom qab ntawd siv Arduino 1.8.2 IDE ntawv qhia zaub mov xaiv Sketch → Import Library → Ntxiv Library los nruab lawv. (Yog tias Arduino tsis tso cai rau koj teeb tsa nws vim tias lub tsev qiv ntawv twb muaj lawm ces nrhiav thiab rho tawm cov pfodParser qub, pfodCmdParser lossis pfodCHAP thiab lwm yam ntawv thiab tom qab ntawv import cov no)

c) Nres thiab rov pib dua Arduino IDE thiab hauv File-> Piv txwv tam sim no koj yuav tsum pom pfodParser, pfodDwgControls thiab pfodESP32BufferedClient cov tsev qiv ntawv thiab ntau tus piv txwv.

Kauj Ruam 3: Siv PfodDesignerV3 rau ESP32

Pub dawb pfodDesignerV3 (V3291+) app txhawb kev tsim cov cai rau ESP32 nti los txuas ntawm BLE, WiFi lossis Bluetooth Classic rau pfodApp (them nyiaj).

Muaj ntau qhov kev qhia uas twb muaj lawm yuav ua li cas los tsim kev tswj hwm rau koj lub xov tooj ntawm tes hauv Android kom tswj tau ntau yam ntawm cov laug cam siv pfodDesignerV3. Nrog pfodDesignerV3 koj tuaj yeem tsim kev tswj hwm uas tso tawm/tso tawm lossis ua haujlwm rau lawv, tswj cov txiaj ntsig ntawm PWM, tso saib lub xeev ntawm cov tswv yim lossis tus nqi sib piv, cav thiab cov phiaj xwm cov ntaub ntawv thiab cov ntawv qhia zaub mov thiab ntau ntxiv.

Tswv yim: ESP32 Arduino kev txhawb nqa suav nrog kev txhawb nqa rau qee 31 pawg ESP32 sib txawv. PfodDesignerV3 muab rau koj nkag mus rau txhua tus ESP32 I/O pins tab sis tsis yog txhua lub rooj sib txuas txuas txhua yam ntawm ESP32 pins rau board pins. Txheeb xyuas koj lub rooj tsav xwm cov ntaub ntawv uas cov pins tau tsim muaj thiab saib pins_arduino.h cov ntaub ntawv hauv qab koj pawg thawj coj saib xyuas kho vajtse / espressif / esp32 / variants directory.

pfodDesignerV3 tus lej npe suav nrog cov lus hais txog kev muaj thiab siv tshwj xeeb pins rau Sparkfun ESP32 Yam thiab Adafruit HUZZAH32 - ESP32 Feather Boards.

Cov piv txwv no siv Sparkfun ESP32 Thing board thiab tsim cov slider los tswj qhov ci ntawm lub onboard LED txuas nrog tus pin 5 los ntawm koj lub xov tooj ntawm tes. Yog tias koj tab tom siv Adafruit HUZZAH32 - ESP32 Feather board hloov chaw ces lub onboard Led txuas nrog tus pin 13. ESP32 Arduino kev txhawb nqa, teeb tsa saum toj no, tsis txhawb Arduino's analogWrite ncaj qha. Hloov chaw ESP32 muaj 16 PWM raws koj tuaj yeem tswj hwm thiab txuas rau ib qho ntawm cov txiaj ntsig. PfodDesignerV3 tsim txhua txoj cai tsim nyog los faib cov channel thiab txuas nws rau qhov koj xaiv tso tawm. Nruab qhov dawb pfodDesignerV3 (V3291+) los ntawm google ua si.
