PoECAM - Building Examples

  • N

    Just a heads up for anyone trying to build the PoeCAM examples or the Ethernet examples.

    Ensure the board is set to M5Stack-Timer-CAM not PoE CAM.

    Additionally the Ethernet-Stream example needs the network.h header lines 16-17 altered as below else it will not compile

    static ip4_addr_t ip_addr; // For platform = espressif32@ ^3.5.0
//static esp_ip4_addr_t ip_addr; // For platform = espressif32@ ^5.1.0

    Ardunio Studio v2 (linux)

    boards package
    esp32 v1.06 boards

    libs
    PoECam lib v0.0.2
    PoECAM ethernet lib v3

    Ext_PIN_1 is at GPIO 33 a simple example of polling a PIR sensor is below :

    #include <Arduino.h>

void setup() {
   
   pinMode(33, INPUT_PULLUP);
   Serial.begin(115200);
}
  
void loop() {

   Serial.println(digitalRead(33));
   delay(1000);
}

    not a 100% sure about the pull-up resistor but I have a vague feeling I read it somewhere, and well it works.

    If anyone knows any other helpful tips, links to examples etc please reply to this thread I am by no means an expert !

    maybe we can get it stickyed or add to the documentation
