ESP8266 SPIFFS leer

[TR.0LL (Gast)]

Hallo,

ich habe das Problem, das ich Daten in den SPI von einem ESP8266 (Wemos 
d1 mini) hochlade, die Daten danach nicht im SPIFFS liegen (Getestet mit 
folgendem Sketch: 
https://github.com/adlerweb/ESP8266Webserver-Tutorial/blob/master/8%20-%20WebServer%20-%20SPIFFS/8.cpp). 
Das Programieren des ESPs und der Upload der Daten in den SPIFFS erfolgt 
mit der aktuellsten Version von PlatformIO in VsCode.

Wieviel Speicher hast du denn für das FS reserviert?

Hallo,

hier ist der Inhalt der platformio.ini-Datei:

[env:d1_mini]
platform = espressif8266@2.0.4
board = d1_mini
framework = arduino
monitor_speed = 115200
;build_flags = -fexceptions
;build_unflags = -fno-exceptions


lib_deps = 
  FastLED@~3.3.3

Wo steht der Wert?
Wie gibt man die größe davon in der platformio.ini-Datei an.

D1_Mini => 
%USERPROFILE%\.platformio\platforms\espressif8266\boards\d1_mini.json => 
"ldscript": "eagle.flash.4m1m.ld"

z.B.
build_flags = -Wall -Wl,-Teagle.flash.4m2m.ld

Im Quellcode fehlt IMHO der Upload handler sowie das Upload formular:

  server.on("/upload", HTTP_GET, []() {                 // if the client requests the upload page
    handleFileUploadDialog();
  });

  server.on("/upload", HTTP_POST,                       // if the client posts to the upload page
    [](){ server.send(200); },                          // Send status 200 (OK) to tell the client we are ready to receive
    handleFileUpload                                    // Receive and save the file
  );


void handleFileUploadDialog(){
    String page = FPSTR(HTTP_HEAD);
    page.replace("{v}", "File Upload");
    page += FPSTR(HTTP_STYLE);
    page += FPSTR(HTTP_JS_IMAGE);
    page += FPSTR(HTTP_HEAD_END);
    page += F("<h1>File Upload</h1><br />");
    page += F("<form action=\"/upload\" method=\"POST\" enctype=\"multipart/form-data\">");
    page += F("<input type=\"file\" name=\"data\">");
    page += F("<input type=\"submit\" value=\"Upload\">");
    page += F("</form>");
    
    page += FPSTR(HTTP_END);

    server.send(200, "text/html", page);

}

void handleFileUpload(){ // upload a new file to the SPIFFS
  HTTPUpload& upload = server.upload();
  if(upload.status == UPLOAD_FILE_START){
    String filename = upload.filename;
    if(!filename.startsWith("/")) filename = "/"+filename;
    Serial.print("handleFileUpload Name: "); Serial.println(filename);
    fsUploadFile = SPIFFS.open(filename, "w");            // Open the file for writing in SPIFFS (create if it doesn't exist)
    filename = String();
  } else if(upload.status == UPLOAD_FILE_WRITE){
    if(fsUploadFile)
      fsUploadFile.write(upload.buf, upload.currentSize); // Write the received bytes to the file
  } else if(upload.status == UPLOAD_FILE_END){
    if(fsUploadFile) {                                    // If the file was successfully created
      fsUploadFile.close();                               // Close the file again
      Serial.print("handleFileUpload Size: "); Serial.println(upload.totalSize);
      handleSuccess();
    } else {
      server.send(500, "text/plain", "500: couldn't create file");
    }
  }
}
