Print 8 characters

[ziomeq21]

Hi I'm new here. I'm writting a code for an Escape Room puzzle. It's about esp-now where one controller is connected to a 3x4 keyboard, and the second one is for controlling the game (it shows what people write from the keyobard). Now, I've got a code that prints every character one by one, and I'd like to have a code that prints every 8 characters together. What should I do? I'm lost.


Here is the code of the keyobard controller, which first part is what I need, cause it's printing only one by one character.
Second part is checking if the code is right with the password.
Third is to reset the code with a " * " character.

Code: Select all

void sendData() {

 char customKey = customKeypad.getKey();
 if (customKey == '*')reset();
 else if (customKey)
 {
  dane[x]= customKey;
  x++;
  Serial.println(customKey);
  uint8_t bs[sizeof(customKey)];
  memcpy(bs, &customKey, sizeof(customKey));
  esp_now_send(mac, bs, sizeof(customKey));
 }
  if ( dane[0]== password[0] &&
      dane[1]== password[1] &&
      dane[2] == password[2] &&
      dane[3] == password[3] &&
      dane[4] == password[4] &&
      dane[5] == password[5] &&
      dane[6] == password[6] &&
      dane[7] == password[7] )
      {
        uint8_t bs[sizeof(work)];
      memcpy(bs, &work, sizeof(work));
      esp_now_send(mac, bs, sizeof(work));
      Serial.println(work.text);;
        
        delay(5000);
        reset();
      }}
void reset() {
  for(int i=0; i<8; i++)
  {
    dane[i]=0;
    x=0;
    uint8_t bs[sizeof(res)];
      memcpy(bs, &res, sizeof(res));
      esp_now_send(mac, bs, sizeof(res));
      
  }Serial.println(res.text);
}

I already made that, if someone would like to know this is how it looks:

Code: Select all

void sendData() {

 char customKey = customKeypad.getKey();
 if (customKey == '*')reset();
 else if (customKey)
 {
  dane[x]= customKey;
  x++;
  if (x==8){
    Serial.println(dane);
    uint8_t bs[sizeof(dane)];
  memcpy(bs, &dane, sizeof(dane));
  esp_now_send(mac, bs, sizeof(dane));
  x=0;
  }
  
  
 }
  if ( dane[0]== password[0] &&
      dane[1]== password[1] &&
      dane[2] == password[2] &&
      dane[3] == password[3] &&
      dane[4] == password[4] &&
      dane[5] == password[5] &&
      dane[6] == password[6] &&
      dane[7] == password[7] )
      {
        uint8_t bs[sizeof(work)];
      memcpy(bs, &work, sizeof(work));
      esp_now_send(mac, bs, sizeof(work));
      Serial.println(work.text);;
        
        delay(5000);
        reset();
      }}
void reset() {
  for(int i=0; i<7; i++)
  {
 
    dane[i]=0;
    x=0;
    uint8_t bs[sizeof(res)];
      memcpy(bs, &res, sizeof(res));
      esp_now_send(mac, bs, sizeof(res));
      
  }Serial.println(res.text);
}
