I don't get it.

Sooo ? Should it work or not ?

Hello. I'm trying to set the MAC of the ETH interface the same as the WiFi interface using the following code: ETH.begin(); uint8_t mac[] = {}; esp_wifi_get_mac(WIFI_IF_STA, &mac[0]); esp_eth_set_mac(&mac[0]); Serial.print("ETH MAC: "); Serial.println(ETH.macAddress()); This prints the right MAC, wh...

I have an ESP32 and a laptop connected to a switch, making a local network with no internet access. I have set the ESP in STA Mode, with an Ethernet connection: ETH.config(local_IP_STA, gateway_STA, subnet_STA, primaryDNS); The gateway is the same as the switch address. The subnet is 255.255.255.0 A...

Hello @GeorgeFlorian1 have a look at the specs of your board: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/esp32/get-started-devkitc.html#power-supply-options BTW: I don't think there is a VIN pin. Thanks Felix I've looked for that page for years and I couldn't find it. ...

What are the 5V and VIN pins used for on a DevKitV4 with ESP32 Wrover-B ?
Can I power the ESP using one of those pins ?

If not, then I am supposed to get a 3V3 power supply and use the 3V3 pin ?

pinMode(GPIO, OUTPUT); digitalWrite(GPIO, STATE); --- pinMode(GPIO, INPUT); or INPUT_PULLUP INPUT_PULLDOWN xxx=digitalRead(GPIO); --- If the pin is configured as an INPUT, digitalWrite() will enable (HIGH) or disable (LOW) the internal pullup on the input pin. It is recommended to set the pinMode()...

Hello. I need an ESP32 variant being able to drive a LED display that uses the following pins: #define R1_PIN GPIO_NUM_12 #define G1_PIN GPIO_NUM_14 #define B1_PIN GPIO_NUM_33 #define R2_PIN GPIO_NUM_25 #define G2_PIN GPIO_NUM_9 #define B2_PIN GPIO_NUM_18 #define A_PIN GPIO_NUM_19 #define B_PIN GPIO...

Input only pins GPIOs 34 to 39 are GPIs – input only pins. These pins don’t have internal pull-ups or pull-down resistors. They can’t be used as outputs, so use these pins only as inputs: GPIO 34 GPIO 35 GPIO 36 GPIO 39 https://randomnerdtutorials.com/esp32-pinout-reference-gpios/ use external pull...

Hello. I am trying to shutdown a PC that runs Linux using an ESP32. The ESP32 should be in softAP() mode and the PC should be connected to it. I've thought of using https://github.com/ewpa/LibSSH-ESP32 to establish a SSH Connection and send a command, but I am unable to figure out how to use that li...
