I have updated my system to the latest esp32 version, and LovyanGFX version. I'm running a esp32s3 with a makersfab 7" lcd. For a while ago included program was working fine, but I think from version 2.017 ESP32 and 1.1.9 LovyanGFX the program is not running any more.
Got the message

with my program:

/*
 * LOVYANGFX 1.1.9
 * ESP32 2.0.17
 * 13-01-2025
 */


#include <SD_MMC.h>
#include "FS.h"
#include <LovyanGFX.hpp>
#include "Matouch7.h"


static LGFX lcd;  

// microSD card
#define PIN_SD_CMD  11
#define PIN_SD_CLK  12
#define PIN_SD_D0   13


void setup() {
  Serial.begin(115200);
  SD_MMC.setPins(PIN_SD_CLK, PIN_SD_CMD, PIN_SD_D0);
  if (!SD_MMC.begin("/sdcard", true, true)) {
    while (1)  {
            Serial.println("Card Mount Failed");
            delay(1000);}
    }
  
  lcd.init();
  lcd.drawPngFile("SD_MMC","/staticmap.png", 100, 40);
}

void loop() {
}

The rest is working perfect. Any idee to get these thing running.
Thanks for any help.
Cheers

hi,

this seems to be the issue:

   lcd.drawPngFile("SD_MMC","/staticmap.png", 100, 40);

try this instead:

  lcd.drawPngFile(SD_MMC,"/staticmap.png", 100, 40);

Hello Have you tried using the SD.h SD card library instead. I have used this with latest LovyGFX library without any issues so far.

Thanks,
Have tried it but the same error(s). When go back to the older version, than it is working. Do I upgrade lovyanGfx with one position it fails to compile. Some kind of wrapper error. I test it with lcd.drawPngFile(SD_MMC,......

let's try something else:

File pngFile = SD_MMC.open("/staticmap.png");
if( pngFile ) {
   lcd.drawPng(&pngFile, 100, 40);
}

No suggestio for those errors:

no known conversion for argument 1 from 'fs::File*' to 'const uint8_t*' {aka 'const unsigned char*'}

no known conversion for argument 1 from 'fs::File*' to 'lgfx::v1::DataWrapper*'

Found the solution; the error disappeared changing this:

....
#include <LovyanGFX.hpp>
#include "FS.h"
#include "SD.h"
#include "SPI.h"
....

so:

....
#include "FS.h"
#include "SD.h"
#include "SPI.h"
#include <LovyanGFX.hpp>
....
