Hi,
I have just downloaded and had a look but I cannot see how you decide what display option to use.
For example in bigfont you have LCD_USE_TFT_280_240_320 which I am guessing is 2.8" 240 x 320 but what controller. Also if you have 8/16 bit as well?
I have a HX8352B display as well, is this covered or is it possible for me to add.

Regards,
Bob

Hi,
Also noticed it is only for PIC18, if I comment out that line what are the chances of it running on PIC24 ?

The library only works on pic18

Supported Interfaces - I2C, SPI, 8080 8-bit

Hi,
How do you select the interface. I have some displays that are similar but one uses spi and the other 8 bit. How do you select the controller type?

All examples are in the file - example.inc

I will be very busy now, so ask the forum members to help you.

Need some help please. Using Windows 11 OS.

Positron 4.0.6.3.

Using this UGL library, I am creating fonts using the GLCD Font Creator. At first I had problems saving the .lcd, and after a Google search I ran it in Windows XP compatibility mode and it saved the file.

Now, when I do an include, i.e. Arial_16x16.inc, the include is being recognised by the compiler, but it is not being recognised by the LCD_SetFont(Arial_16x16).

What can I do to solve the issue please?

Also, I have an ST7789, 1.5", 240x240.

Am I correct to use the LCD_Select(LCD_TFT_130_240_240)? Seems that printing lines is ok at from position 0 to 240, but I discovered that I do not need to use any negative numbers for text / line position.

How can I select transparent background for text, and how to set full background colour to LCD?
