Variable or field 'writeFile' declared void ESP32 CAM

Projects Programming

Hi there,

I'm building an ESP32 Cam PIR Telegram using a mixture of Rui Santos's and Brian Lough's code.

I have added extra features as I discover more like Telegram app buttons to request temp, humidity, battery voltage etc. This is all working fine and I have impressed my self with getting this far!

I would like to now add data logging of the battery voltage using the onboard SD card slot on the ESP32 Cam module. I have trimmed Rui Santos's ESP32 (not cam) SD card example code down and managed to get it compiled and working on the my ESP32 Cam writing an int to the SD card. Code here.....


#include "FS.h"
#include "SD_MMC.h"

unsigned long aNumberIncreasingByOne = 100;

String dataMessage;

int readingID = 0;


void setup() {
  Serial.begin(115200);
  Serial.println("SDcard Testing....");

  if (!SD_MMC.begin()) {
    Serial.println("Card Mount Failed");
    return;
  }
  uint8_t cardType = SD_MMC.cardType();

  if (cardType == CARD_NONE) {
    Serial.println("No SD_MMC card attached");
    return;
  }

  Serial.print("SD_MMC Card Type: ");
  if (cardType == CARD_MMC) {
    Serial.println("MMC");
  } else if (cardType == CARD_SD) {
    Serial.println("SDSC");
  } else if (cardType == CARD_SDHC) {
    Serial.println("SDHC");
  } else {
    Serial.println("UNKNOWN");
  }

  uint64_t cardSize = SD_MMC.cardSize() / (1024 * 1024);
  Serial.printf("SD_MMC Card Size: %lluMB\n", cardSize);


  writeFile(SD_MMC, "/data.txt", "Hello ");

}



void loop() {

  dataMessage = String(readingID) + " )  " + String(aNumberIncreasingByOne) + "\r\n";
  Serial.print("Save data: ");
  Serial.println(dataMessage);
  appendFile(SD_MMC, "/data.txt", dataMessage.c_str());

  delay(1000);

  readingID++;
  Serial.println(readingID);

  aNumberIncreasingByOne++;

}



//Write a file in SD card
void writeFile(fs::FS &fs, const char * path, const char * message) {
  Serial.printf("Writing file: %s\n", path);

  File file = fs.open(path, FILE_WRITE);
  if (!file) {
    Serial.println("Failed to open file for writing");
    return;
  }


  //fwrite(fb->buf, 1, fb->len, file);
  if (file.print(message)) {
    Serial.println("File written");
  } else {
    Serial.println("Write failed");
  }
}



//Append to the end of file in SD card
void appendFile(fs::FS &fs, const char * path, const char * message) {
  Serial.printf("Appending to file: %s\n", path);

  File file = fs.open(path, FILE_APPEND);
  if (!file) {
    Serial.println("Failed to open file for appending");
    return;
  }
  if (file.print(message)) {
    Serial.println("Message appended");
  } else {
    Serial.println("Append failed");
  }
}

I am now trying to incorporate this code into my ESP32 Cam PIR Telegram code an am getting the compiling error "variable or field 'writeFile' declared void"

In the loop I will be calling a read of the battery voltage every 3 second then a writeFile to the on board SD card on the ESP32 Cam. Currently it is set up to just write readingID and aNumberIncreasingByOne. The relevant handlers are just below the loop FYi. Code here.......

I have made substantial conquests in my learning but this one has got stumpt. I have trawled the forums on this and there is quite a bit on it. Unfortunately I am struggling to understand what the problem is and what the solution is. I'm hoping it is something basic that I have missed/skipped/not got. In fact I'm pretty sure it me me skipping some basic rule!

I hope I have formatted this post correctly.

Any help greatly appreciated!

Kind regards

Could you copy the full compiler error. There is extra information there

Thank you.

Added full compiler error.

Understood. I am not as experienced as you. It will not happen again.

#include "FS.h" is included in my code

#include "SD.h" is not but #include "SD_MMC.h" is. I have tried each and both no go

#include "SPI.h" was not included in my code. I have added but no go.

Slightly different compiler error now with them all added......

This report would have more information with

post the full code. It smells like you are missing a { somewhere and that the function definition might be stuck within another function or something like that

Indenting the code would help see that

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project :wink: See About the Installation & Troubleshooting category.

Understood, where should have I put it.

12

So I have learnt now from this that you need to get all #includes at the very beginning no if, buts, or hair cuts! This has probaly been the root of the problem. Testing that now!

13

Thanks a million. Will test shortly.

14

For me, the most sensible place is the Programming Questions section as the error message indicated a programming error. So that is where it was moved to.

Why did you change #include <Adafruit_ADS1015.h> to #include <Adafruit_ADS1X15.h> ?

Does not compile for me unless I use #include <Adafruit_ADS1015.h> and Adafruit_ADS1115 ads(0x48);

I remember vaguely there was an issue with #include <Adafruit_ADS1X15.h> and using #include <Adafruit_ADS1015.h> was the work around.

Also why did you add void renameFile and void deleteFile? My working example of basic ESP32 Cam SD card write only uses void writeFile and void appendFile which is all I need.

For me I used the writeFile(SD_MMC, "/data.txt", "Hello "); to create the folder end of setup then use void appendFile to append that folder with the next reading.

This code says its writing in the serial monitor to the SD card but no directory/files are written. It is also boot looping the ESP32 Cam board and not engaging the code past the setup i.e........

String welcome = "Welcome to BARN PiR CAM 1.\n";
welcome += "/options : Gives you some buttons\n";

bot.sendMessage(chatId, welcome, "Markdown");

....is not going out to telegram at start up. Forgive me if that did not need mentioning.

Your code that now compiles with mentioned #include revert.......

#include "FS.h"
#include "SD.h"
#include "SPI.h"

option enabled in File -> Preferences.

I know my libraries are a bit of a mess.

Thanks for all your help so far definitely. Much appreciated!

Actually, I see that I'm unable to help you. Just delete the code I said that works and go back to your old code. Perhaps someone else can solve your issue. Good luck and sorry to have bothered you.

18

Ahh-man! Ok.

Thank you for having a go mate!
