I have a display without a touchscreen, what should I change to make the display work?

Thanks! I will do continue upgrading this repository.

It works fine but if you use a dynamic font (for example, a voltmeter, no refresh)
Can fix in functions
Static Void LCD_Char (int16_t x, int16_t y, const gfxglyph * glyph, const gfxfont * font, uint8_t size, uint32_t color24)
thanks

Try
LCD_Font(5, 100, "01.23", _64_Segment_7_Num, 1,TFT9341_WHITE);
HAL_Delay(1000);
LCD_Font(5, 100, "65.32", _64_Segment_7_Num, 1,TFT9341_WHITE);
HAL_Delay(1000);

In _64_Segment_7_Num, there is no point(".")
Can you add?
Which font generator are you using?

Static text, excellent. Dynamic does not work.
You try this code.

LCD_Font(5, 100, "01.23", _64_Segment_7_Num, 1,WHITE);
HAL_Delay(1000);
LCD_Font(5, 100, "65.32", _64_Segment_7_Num, 1,WHITE);
HAL_Delay(1000);

Sorry, but I don't understand, what you mean "dynamic text". If you want just overwrite old text to new, you must save in variable old value and print this in background colour before printing updated text. Example here https://github.com/anothermist/STATION_SSD1963_F103C8T6/tree/main/00_STATION
If you use ONLY(!) monospaced fonts, you can overwrite every symbol with empty space.

In this code you don’t have any command to clear old text before writing new.

// BLACK – is background color, ORANGE – is text color. Printing float example with overwrite old text

In your code you can just override old text with background colour

print Connected:
LCD_Font(50, 20, "Disconnected", _12_Serif_Bold_Italic, 1, BACKCOLOR);
LCD_Font(50, 20, "Connected", _12_Serif_Bold_Italic, 1, GREEN);

print Disconnected:
LCD_Font(50, 20, "Connected", _12_Serif_Bold_Italic, 1, BACKCOLOR);
LCD_Font(50, 20, "Disconnected", _12_Serif_Bold_Italic, 1, GREEN);

OR create array and use sprintf (a lot examples here https://github.com/anothermist/STATION_SSD1963_F103C8T6/blob/main/00_STATION/Src/main.c)
