Loading a ttf font to the M5paper from the sdcard causes error "but zero-sized" #14

Closed dov closed 7 months ago

dov commented 3 years ago

What I did:

  1. Mounted a 16GB sd card to my desktop
  2. Created the directory /ttf in the root directory
  3. Copied over the font DejaVuSans.ttf to the sdcard to the directory /ttf
  4. Wrote an arduino sketch with the following code snippet in setup()
esp_err_t ret = cnv.loadFont("/ttf/DejaVuSans.ttf", SD);
  1. Compiled uploaded, opened serial monitor.
  2. Result: Get the following message in the serial monitor:
FT_Stream_Open: opened `/ttf/DejaVuSerif.ttf' but zero-sized

m5EPD version: 0.1.0

Same error

dov commented 10 months ago

It really doesn't seem like anyone cares/is listening...

eggfly commented 10 months ago

@dov But don't worry maybe I've found why this error appeared. Which file system did you use in tf card?

dov commented 10 months ago

@eggfly I probably used FAT32, but it's been a couple of years. What did you find out?

icyqwq commented 7 months ago

This appears to be a file system error. It may be due to a malfunctioning SD card or an incorrect file path, among other potential causes.

@icyqwq How was this completed? What was done?

icyqwq commented 7 months ago

Try moving the file to the root directory and renaming it to f.ttf. Since the maximum file name length for FS under default settings is 8 bytes, which might be the reason the font file can't be loaded. Additionally, please provide your font file for me to test.

Please reopen this issue if needed.
