TFT display

320x240 pixels
One of the most powerful ways of presenting
data and interacting with users is through
color displays and touch panel inputs. This is
a crucial element of any multimedia device.
EasyMx v7a features EasyTFT board carrying
320x240 pixel 2.83" color TFT display with
LED back-light and HX8347D controller.
In order to use PWM back-light both SW11.3
and SW11.4 switches must be enabled at the
same time.

TFT display is enabled using SW11.3 and SW11.4 DIP
switches. Back-light can be enabled in two different
VCC-5V
ways:
PE9
1. It can be turned on with full brightness using SW11.3
switch.
SW13
2. Brightness level can be determined with PWM signal
from the microcontroller, allowing you to write custom
back-light controlling software. This back-light mode
is enabled when both SW11.3 and SW11.4 switches
are in ON position.
Each pixel is capable of showing 262.144
different colors. TFT display is connected
to microcontroller PORTE using standard
8080 parallel 8-bit interface, with additional
control lines. Board features back-light
driver which besides standard mode can
also be driven with PWM signal in order to
regulate brightness in 0 to 100% range.
