How can I convert this default adafruit font to a format that works with this library? https://github.com/vindar/tgx
Im using vscode with platformio and using teensy 4.1.

This is the format of the font i want:

glcdfont.c
Code: 
// This is the 'classic' fixed-space bitmap font for Adafruit_GFX since 1.0.
// See gfxfont.h for newer custom bitmap font info.

#ifndef FONT5X7_H
#define FONT5X7_H

#ifdef __AVR__
#include <avr/io.h>
#include <avr/pgmspace.h>
#elif defined(ESP8266)
#include <pgmspace.h>
#elif defined(__IMXRT1052__) || defined(__IMXRT1062__)
// PROGMEM is defefind for T4 to place data in specific memory section
#undef PROGMEM
#define PROGMEM
#else
#define PROGMEM
#endif

// Standard ASCII 5x7 font

static const unsigned char font[] PROGMEM = {

Hi,

The TGX library has native support for ILI9341_t3 and Adafruit GFX font format (GFXFont). However, the default 'classic' 6x8 Adafruit font given in glcdfont.h is strangely not in Adafruit GFXFont format for some (probably historical) reasons so it need to be converted. Here it is converted to GFXFont:

classicGFXfont.h
Code: 
#ifndef _CLASSICGFXFONT_H_
#define _CLASSICGFXFONT_H_


#include "tgx.h"


// the 'classic' Adafruit GFX font converted to the new Adafruit font format. 
extern const GFXfont classicGFXfont;

#endif

and classicGFXfont.cpp
Code: 
#include "classicGFXfont.h"
