there is no CS1, CS2 and DC pin on BT 81X , there only have SCK, MISO, MOSI ,CS pin etc . how to do?

Is there any example on how to load the custom font using this library ?

Hello blazer82,

I've built my own FT81x driver board, following your excellent design, and have got the display up and running with some of the examples from your library.

However, in starting to draw my own screens, I find that the rectangles are not displaying at all.

For example:
ft81x.drawCircle(20,20,4,FT81x_COLOR_RGB(255, 0, 0)); will draw successfully, but
ft81x.drawRect(20,20,4,4,0,FT81x_COLOR_RGB(255, 0, 0)); will not display anything.

Is there a known error in the rectangle drawing routine? It appears to correctly follow the FT81x programming guide. Could this be a fault with the driver chip or hardware fault?

Hi,
Great Library.
Btw, why are those red and blue color data lines exchanged in the schematic?

Hello Raphael.
Would you please tell me how did you get array of image data in const uint8_t jpegData[] PROGMEM = {...};
Is there any program for convert jpeg/png images to array?

Best regards,
Sergey

When I open the .brd file in KiCad 5.0.2, all the filled zones on the board are gone (GND on F.Cu, +3V0 and +5V on B.Cu). The filled zones are present in the Gerbers, maybe our versions of KiCad are incompatible?

Hello! I would like to manufacture the board for myself, but some components are unavailable both in DigiKey and Mouser where I checked. I managed to select components based on the BOM exported from the KiCad project. To stay with what is available, I had to swap some components, in particular the crystal and power ICs. I'm also unsure if there are any passives' characteristics that I need to consider (e.g. I selected everything for 16V max).

Would you be so kind to take a look at my component list and comment on the choices? Here's the link to the details, I also include a screenshot below: https://www.mouser.ca/ProjectManager/ProjectDetail.aspx?AccessID=994f0071b4
