“EVE”
Embedded
Video Engine
Typical Hardware
Current designs usually require
•
High-end µC typically 32-bit with abundant IO + external
memory
 Higher cost and board area
•
Graphics library and sometimes an Embedded OS required
•
Expensive frame buffer IC required for display memory
•
Touch and audio implementations needed
FT800 Hardware
•
•
•
•
•
•
Low cost MCUs enabled (ATMEGA 328, PIC, 8051, etc)
48 pin QFN for reduced PCB area
SPI/I²C interface options for reduced pins, simple interface
262k colour (RGB – 6,6,6) WQVGA graphics
Touch controller

“EVE”
Key features
and benefits
Key Features and
benefits
The FT800’s object oriented approach renders
images in a line by line fashion with 1/16th of
a pixel resolution
•
No expensive frame buffer (less RAM)
required lowering system cost
• Anti-Aliasing
•
Allows the FT800 to produce sharper,
smoother edges with enhanced image
quality, even on lower resolution
displays.
• Alpha blending and masking algorithms
• Create shadows / 3D / fade effects
•In-built widgets for complex shapes
• Colour Dither
• Allows the FT800 to calculate for 8-bit
colour despite only providing pins for 6-bit
(RGB – 6,6,6)
• Improves half-tone appearance
• 8kbyte RAM stores display list
• Approximately 2000 items
• Programmable Timing
• Allows the FT800 to adjust HSYNC and
VSYNC timing enabling control of many
different displays.
Key Features and
benefits
•
•
•
Mono audio (single pin) output from
PWM
64-voice polyphonic synthesiser
– Play pre-stored sounds
allowing for fast implementation
of sound generation e.g. bells,
chirps, beeps, alarms, clicks,
DTMF tones
Audio wave playback for mono-8-bit
linear PCM, 4-bit ADPCM and µ-Law
coding format at sampling frequency
from 8kHz to 48kHz
•
Designed for resistive touch screens
•
Includes median filtering and touch force
sensing to adjust the screens sensitivity.
•
4 wire control (X+, X-, Y+, Y-)
•
Screen pressure alters
resistance between the +/signals with the value
returned to the FT800.
•
10 bit ADC + processing
enables location to be
determined.
Design Cycle
1.
2.
Select your FT800
hardware
Confirm your
Controller
3.
Utilise the
appropriate compiler
4.
Design your
application
Do you
require Audio?

Development
flow:
7 Stages
Startup & Config
1.
Configure the SPI/I2C interface
•
SPI supports Mode 0 to 30MHz
•
I2C supports up to 3.4Mbit/s
2. Wake up the FT800
•
Fundamentally a dummy read to address 0 and configure the PLL
Startup
3. Configure the TFT display timing parameters
•
Many displays will have different timing for horizontal and vertical sync.
•
FT800 has a set of 10 registers to set the synchronisation
•
FT800 has 3 additional registers to control actual pixel clocking:
FT_DispPCLK – Pixel clock divisor
FT_DispSwizzle – Sync of RGB pixel clocking
FT_DispPCLKPol – Polarity of clock
Startup & Config

4. Configure the TFT display touch parameters
•
Theoretically only required if using the touch function.
•
19 registers to control sensitivity (charge and settle) and monitor feedback
•
Key ones are:
o
Reg_Touch_Mode_Definition
o
Reg_Touch_Charge_Definition
o
Reg_Touch_Settle Definition
o
Values dependant upon display
FT800 Step 2
Create the Code (part 3)
Enable the LCD
•
5. Create the display list
•
Multiple paths for this.
•
Direct to 8kRAM (2000 objects)
Note: An object may be visual, audio or touch.
•
Via j1 co-processor.
6. Complete and swap the display list
7. Compile and load the code into the system

What are
display objects?
FT800 Graphic objects
‘EVE’ displays are created using two
primary types of objects:
•
•
Primitive objects (simple
shapes)
Widget objects
FT800 Graphic
Primitives – Basic Shapes
•
POINTS – anti-aliased points, point
radius is 1-256 pixels
•
LINES – anti-aliased lines, with width
of 1-256 pixels (width is from center
of the line to boundary)
FT800 Graphic
Primitives – Basic Shapes
•
LINE STRIP – anti-aliased lines,
connected head-to-tail
•
EDGE STRIP – Above, Below, Left,
Right – anti aliased edge strips

•
RECTS – round-cornered anti-aliased
rectangles (curvature of the corners
can be adjusted using LINE WIDTH)
•
BITMAPS – rectangular pixel arrays,
in various color formats
