4D SYSTEMS µLCD-24PTU
© 2014 4D SYSTEMS Page 4 of 21 www.4dsystems.com.au
1. Description
The μLCD-24PTU module demonstrates class and
finesse in the microLCD range, featuring a 2.4’’
240x320 screen resolution that is the ideal size for
displaying detailed graphics for many interactive
touch applications.
Driving the display and peripherals is the PICASO
processor, a very capable and powerful chip which
enables stand-alone functionality, programmed
using the 4D Systems Workshop 4 IDE Software.
The Workshop IDE enables graphic solutions to be
constructed rapidly and with ease due to its design
being solely for 4D’s graphics processors.
The module has an array of features including PWM
for Sound, Touch Detection, micro-SD memory
storage, Lithium battery support, general purpose
I/O, serial communications, an I2C interface and
multiple millisecond resolution timers, amongst
many more features.
