ft81x_arduino_driver's Introduction

FT81x Arduino Driver

High quality display module for many Arduino project ideas!

Hardware

Schematics, KiCad files and Gerber files can be found inside the hardware folder in this repository.

The board is compatible with this display.

The complete hardware is available for sale on Tindie.

Highlights

4 inch 480x480 pixel TFT display
up to 24 bit color support
19 built-in fonts
built-in widgets (e.g. buttons, gauges, clock)
hardware support for JPEG and PNG
built-in sound effects (audio circuitry required)
bitmap support with 1 MByte graphics RAM
open source Arduino library with many example sketches
compatible with 3.3V and 5V logic levels

Supported Boards

The hardware and software has been tested with the following boards:

✔️ Arduino Uno (ATmega328P)
✔️ Arduino Nano (ATmega328)
✔️ Arduino Nano Every (ATMega4809)
✔️ Arduino Due (AT91SAM3X8E)
✔️ NodeMCU-32S (ESP32)
✔️ Teensy 4.0 (ARM Cortex M7)

If your board is missing and has full Arduino support chances are that it's fully supported by this library, too.

If you have tested additional boards (successfully or unsuccessfully) feel free to contact me or open an issue.

Usage

#include "FT81x.h"

FT81x ft81x = FT81x(10, 9, 8);

void setup() {
    SPI.begin();
    ft81x.begin();

    ft81x.beginDisplayList();
    ft81x.clear(FT81x_COLOR_RGB(0, 0, 0));
    ft81x.drawText(240, 200, 31, FT81x_COLOR_RGB(255, 255, 255), FT81x_OPT_CENTER, "Hello World\0");
    ft81x.swapScreen();
}

For more information see the numerous example sketches as well as the API Documentation.

Loading custom font

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

Image.ino

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

Unable to draw rectangle

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?

No CS1, CS2 and DC pin

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

Just Curious About RGB wiring of FT813 and ST7701S

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

Wrong constant define: FT81x_BITMAP_LAYOUT_ARGB1555 should be 0x00, not 0x01.

Line 156 of FT81x_Arduino_Driver/src /FT81x.h is:

#define FT81x_BITMAP_LAYOUT_ARGB1555 0x1  ///< Bitmap pixel format ARGB1555

but it should be (from FT81x programming manual):

#define FT81x_BITMAP_LAYOUT_ARGB1555 0x0

With this definition is possible to copy-paste-modify the drawBitmap function and obtain a routine with the 1-bit alpha display (quick and dirty way, but works), changing the bitmap layout command replacing FT81x_BITMAP_LAYOUT_RGB565 with FT81x_BITMAP_LAYOUT_ARGB1555:
like this:

 intermediateCmd(BITMAP_LAYOUT(FT81x_BITMAP_LAYOUT_ARGB1555, (uint32_t)width * 2, (uint32_t)height));  // only supporting one format for now

Best regards,
Dino.

No filled zones on driver board

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?

Replacements for missing components

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
