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

[Vitalij1967]

The library is super!

[anothermist]

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

[Vitalij1967]

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.

I found this code, but I can't figure out how to use it in my code.

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)
