v7
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. EasyPIC Fusion
™
v7 features TFT
color 320x240 pixel display. It is a 2.83" display with
LED back-light, featuring HX8347D controller.
Each pixel is capable of showing 262.144 dierent
colors. It is connected to microcontroller 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 range from 0 to 100%.
TFT display
320x240 pixels
TFT display is enabled using SW11.1–SW11.2
DIP switches. Back-light can be enabled in two
dierent ways:
1. It can be turned on with full brightness
using SW11.1 switch.
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 SW11.1 and SW11.2 switches
are in ON position.
