Just an ESP32-CAM Forum?

Postby RogerInHawaii » Sun Sep 27, 2020 10:01 pm

It seems that there is no forum for just the ESP32-CAM. There's a forum (THIS FORUM) regarding the facial recognition software for the ESP32-CAM, but there's no forum that deals with just the issues related to the ESP32-CAM in general.

I've had some questions regarding the ESP32-CAM which really just relate to operating the camera's basically functionality and really has nothing to do with the facial recognition(or any other) software, but this seems to be the only forum where I (and apparently others) can ask general questions about the camera.

Please, whoever is in charge of these forums, could you add just a general ESP32-CAM forum?

Thank you

The ESP-CAM is not one of our development boards (the ESP-EYE is.) If you have issues with hardware, you can post those in the 'hardware' subforum, but again, support on the ESP-CAM will be best-effort as we do not produce these boards.

Is there an ESP32-CAM forum somewhere else on the web?

i have a problem i write this code:

Code: Select all

#include <BleKeyboard.h>

BleKeyboard bleKeyboard;
int gnd = 15;
int p1 = 13;
int p2 = 14;
int p3 = 4;
unsigned long last_run = 0;

void setup() {
  pinMode(gnd,OUTPUT);
  digitalWrite(gnd,LOW);
  pinMode(p1,INPUT);
  attachInterrupt(digitalPinToInterrupt(p2),a,RISING);
  attachInterrupt(digitalPinToInterrupt(p3),b,HIGH);
  Serial.begin(115200);
  
    bleKeyboard.begin();
  
}

void b(){
  Serial.println("enter");
    bleKeyboard.press(0xE0);
    bleKeyboard.releaseAll();
}
void a(){
  if(millis()-last_run>10){
  if(digitalRead(p1)){
  Serial.println("up");
    bleKeyboard.press(KEY_UP_ARROW);
    bleKeyboard.releaseAll();
  }else{
  Serial.println("down");
    bleKeyboard.press(KEY_DOWN_ARROW);
    bleKeyboard.releaseAll();
  }
    last_run = millis();
  }
}

void loop() {
}
and when i run it some times it crash and rapidly write this

Code: Select all

i want to know why is this happening?
is it something related to the library and not mine?
how can i fix it?
thanks in advance.

It might be because you do a Serial.println() in an ISR; I'm not entirely sure about Arduino but in ESP-IDF, doing a printf is not allowed in an ISR. Try to remove those lines.
