<p>Hello,</p><p>I am a new use to TTGO board with a display and also to MicroPython. I was trying to use custom font and used the online tool mentioned in the forum:</p><p>https://loboris.eu/forum/showthread.php?tid=826<br></p><p><br></p><p>I have generated the .c file and used the tft.compileFont() function to generate the .fon file. As I have used "debug=True", I could see the error as:&nbsp;</p><p><br></p><p>Error opening source file '/_#!#_spiffs/&lt;file_name&gt;.c'</p><p><br></p><p>Is it because I have kept the .c file at the wrong location? Where should I keep it?</p><p><br></p><p><br></p><p><br></p><p><br></p>
