Arduino Application
If using or prototyping this EVE2 TFT Module with the low-cost, widely popular Arduino platform we highly recommend
using our Arduino shield, the NHD-FT81x-SHIELD. Not only does the NHD-FT81x-SHIELD provide seamless connectivity
and direct software compatibility for the user, but it also comes with the following useful features on-board:
•logic level shifters to allow the 5V Arduino to communicate with the 3.3V FT81x
•regulators to allow the Arduino to output more current to the EVE2 TFT Module
•audio filter/amplifier circuit to utilize the EVE2 TFT Module’s audio output signal
•microSD card slot, which allows expandable storage for data such as images, video, and audio to be stored.
Please visit the NHD-FT81x-SHIELD product webpage for more info.

Backlight Driver Configuration
The Backlight Driver Enable signal is connected to the FT81x backlight control pin. This signal is controlled by two
registers: REG_PWM_HZ and REG_PWM_DUTY. REG_PWM_HZ specifies the PWM output frequency –the range
available on the FT81x is 250 to 10KHz and the on-board backlight driver’s PWM frequency is 800 to 100KHz. Therefore,
for proper use of the PWM function available on this module, the PWM frequency should not go below 800 or exceed
10KHz.
REG_PWM_DUTY specifies the duty cycle –the range is 0 to 128. A value of 0 turns the backlight completely off, while a
value of 128 provides maximum backlight brightness.
For the above register definitions, please refer to pages 80-81 of the official FT81x Series Programmers Guide:
http://www.ftdichip.com/Support/Documents/ProgramGuides/FT81X_Series_Programmer_Guide.pdf

FT81x Block Diagram
FT81x with EVE (Embedded Video Engine) technology simplifies the system architecture for advanced Human Machine
Interfaces (HMIs) by providing support for display, touch, and audio as well as an object oriented architecture approach
that extends from display creation to the rendering of the graphics.
Serial Host Interface
By default the SPI slave operates in the SINGLE channel mode with MOSI as input from the master and MISO as output
to the master. DUAL and QUAD channel modes can be configured through the SPI slave itself. To change the channel
modes, write to register REG_SPI_WIDTH. Please refer to the table below:

Graphics Engine
The graphics engine executes the display list once for every horizontal line. It executes the primitive objects in the
display list and constructs the display line buffer. The horizontal pixel content in the line buffer is updated if the object is
visible at the horizontal line.
Main features of the graphics engine are:
•The primitive objects supported by the graphics processor are: lines, points, rectangles, bitmaps (comprehensive
set of formats), text display, plotting bar graph, edge strips, and line strips, etc.
•Operations such as stencil test, alpha blending and masking are useful for creating a rich set of effects such as
shadows, transitions, reveals, fades and wipes.
•Anti-aliasing of the primitive objects (except bitmaps) gives a smoothing effect to the viewer.
•Bitmap transformations enable operations such as translate, scale and rotate.
•Display pixels are plotted with 1/16th pixel precision.
•Four levels of graphics states
•Tag buffer detection
The graphics engine also supports customized built-in widgets and functionalities such as jpeg decode, screen saver,
calibration etc. The graphics engine interprets commands from the MPU host via a 4 Kbyte FIFO in the FT81x memory at
RAM_CMD. The MPU/MCU writes commands into the FIFO, and the graphics engine reads and executes the commands.
The MPU/MCU updates the register REG_CMD_WRITE to indicate that there are new commands in the FIFO, and the
graphics engine updates REG_CMD_READ after commands have been executed.
Main features supported are:
•Drawing of widgets such as buttons, clock, keys, gauges, text displays, progress bars, sliders, toggle switches,
dials, gradients, etc.
•JPEG and motion-JPEG decode
•Inflate functionality (zlib inflate is supported)
•Timed interrupt (generate an interrupt to the host processor after a specified number of milliseconds)
•In-built animated functionalities such as displaying logo, calibration, spinner, screen saver and sketch
•Snapshot feature to capture the current graphics display
For a complete list of graphics engine display commands and widgets, please refer to Chapter 4 of the official
FT81x Series Programmers Guide:
http://www.ftdichip.com/Support/Documents/ProgramGuides/FT81X_Series_Programmer_Guide.pdf

Touch-Screen Engine
The Capacitive Touch Screen Engine (CTSE) of the FT813 communicates with the external Capacitive Touch Panel Module
(CTPM) through an I2C interface. The CTPM will assert its interrupt line when there is a touch detected. Upon detecting
CTP_INT_N line active, the FT813 will read the touch data through I2C. Up to 5 touches can be reported and stored in
FT813 registers.
For more details on the FT813 Touch-Screen Engine, please refer to pages 32-35 of the official FT81x Datasheet:
https://support.newhavendisplay.com/hc/en-us/articles/6963170802839-FT81x
Audio Engine
The FT81x provides mono audio output through a PWM output pin, AUDIO_L. It outputs two audio sources, the sound
synthesizer and audio file playback.
This pin is designed to be passed into a simple filter circuit and then passed to an amplifier for best results. Please refer
to the example schematic in the Audio Filter and Amplifier Reference Circuit section on the next page.
Sound Synthesizer
A sound processor, AUDIO ENGINE, generates the sound effects from a small ROM library of waves table. To play a
sound effect listed in Table 4.3, load the REG_SOUND register with a code value and write 1 to the REG_PLAY register.
The REG_PLAY register reads 1 while the effect is playing and returns a ‘0’ when the effect ends. Some sound effects
play continuously until interrupted or instructed to play the next sound effect. To interrupt an effect, write a new value
to REG_SOUND and REG_PLAY registers; e.g. write 0 (Silence) to REG_SOUND and 1 to PEG_PLAY to stop the sound
effect.
The sound volume is controlled by register REG_VOL_SOUND. The 16-bit REG_SOUND register takes an 8-bit sound in
the low byte. For some sounds, marked "pitch adjust" in the table below, the high 8 bits contain a MIDI note value. For
these sounds, a note value of zero indicates middle C. For other sounds the high byte of REG_SOUND is ignored.
Audio Playback
The FT81x can play back recorded sound through its audio output. To do this, load the original sound data into the
FT81x’s RAM, and set registers to start the playback. The registers controlling audio playback are:
REG_PLAYBACK_START:
The start address of the audio data.
REG_PLAYBACK_LENGTH:
The length of the audio data, in bytes.
REG_PLAYBACK_FREQ:
The playback sampling frequency, in Hz.
REG_PLAYBACK_FORMAT:
The playback format, one of LINEAR SAMPLES, uLAW SAMPLES, or
ADPCM SAMPLES.
REG_PLAYBACK_LOOP:
If ‘0’, the sample is played once. If ‘1’, the sample is repeated indefinitely.
REG_PLAYBACK_PLAY:
A write to this location triggers the start of audio playback, regardless of
writing ‘0’ or ‘1’. Read back ‘1’ when playback is ongoing, and ‘0’ when
playback finishes.
REG_VOL_PB:
Playback volume, 0-255.
The mono audio formats supported are 8-bits PCM, 8-bits uLAW and 4-bits IMA-ADPCM. For ADPCM_SAMPLES, each
sample is 4 bits, so two samples are packed per byte, the first sample is in bits 0-3 and the second is in bits 4-7.
The current audio playback read pointer can be queried by reading the REG_PLAYBACK_READPTR. Using a large sample
buffer, looping, and this read pointer, the host MPU/MCU can supply a continuous stream of audio.
For more details on the FT81x Audio Engine, please refer to pages 30-32 of the official FT81x Datasheet:
