Iinkcukacha

Imiyalelo yokusetyenziswa kwemveliso

Ukuseta i-IDE yeArduino

1. Ndwendwela igosa leArduino webindawo (https://www.arduino.cc/en/Main/Software) ukukhuphela umqulu wofakelo wendlela yakho yokusebenza.
2. Vula i-Arduino IDE kwaye ukhangele ukuya `File`->` Ezikhethwayo`->` Useto`
3. Khuphela lo ulandelayo M5Stack Boards Manager URL 'kuMphathi weeBhodi ezoNgezelelweyo URLs:` https://raw.githubusercontent.com/espressif/arduino-esp32/ghpages/package_esp32_dev_index.json
4. Layisha uye ku `Izixhobo`->` Ibhodi:`->`Umphathi weebhodi...`
5. Khangela i `ESP32` kwifestile ezivelelayo, fumana kwaye ucofe `Fakela`
6. Khetha `Izixhobo`-> `Ibhodi:`-> `ESP32-Arduino-ESP32 DEV Imodyuli`
7. Faka umqhubi we-FTDI ngaphambi kokusetyenziswa: https://docs.m5stack.com/en/download

Uthotho lweBluetooth

1. Vula i-Arduino IDE kwaye uvule i-example nkqubo `File`->`Eksamples`->` Uthotho lweBluetooth`->` Uthotho lwe BT`.
2. Xhuma isixhobo kwikhompyuter kwaye ukhethe i-port ehambelanayo ukutshisa.
3. Emva kokugqiba, isixhobo siya kusebenzisa iBluetooth ngokuzenzekelayo, kwaye igama lesixhobo lithi `ESP32test`.
4. Sebenzisa isixhobo sokuthumela isisiriyali seBluetooth kwiPC ukuqonda ukuhanjiswa okusekuhleni kwedatha yeBluetooth.
5. Nantsi i-example khowudi snippet:

#include BluetoothSerial.h
#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED) #error Bluetooth is not enabled! Please run `make menuconfig` to and en able it #endif
BluetoothSerial SerialBT;
void setup() { Serial.begin(115200);
SerialBT.begin("ESP32test"); //Bluetooth device name
Serial.println("The device started, now you can pair it with bluetooth!"); }
void loop() { if (Serial.available()) { SerialBT.write(Serial.read()); } if (SerialBT.available()) { Serial.write(SerialBT.read()); } delay(20); }

Ukuskena kweWifi

1. Vula i-Arduino IDE kwaye uvule i-example nkqubo `File`->`Eksamples`->`WIFI`->` Iskena seWIFI`.
2. Xhuma isixhobo kwikhompyuter kwaye ukhethe i-port ehambelanayo ukutshisa.
3. Emva kokugqitywa, isixhobo siya kuqhuba ngokuzenzekelayo ukuskena kwe-WIFI, kwaye isiphumo se-WIFI yangoku sinokufumaneka nge-serial port monitor esiza kunye neArduino.
4. Nantsi i-example khowudi snippet:

#include WiFi.h
void setup() {
Serial.begin(115200);
// Set WiFi to station mode and disconnect from an AP if it was previously connected
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
Serial.println("Setup done");
}
void loop() {
Serial.println("scan start");
// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println("scan done");
if (n == 0) {
Serial.println("no networks found");
} else {
for (int i = 0; i < n; ++i) {
// Print SSID and RSSI for each network found
Serial.print(i + 1);
Serial.print(": ");
Serial.print(WiFi.SSID(i));
Serial.print(" (");
Serial.print(WiFi.RSSI(i));
Serial.print(")");
Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN)?" ":"*");
delay(10);
}
}
Serial.println("");
// Wait a bit before scanning again
delay(5000);
}
