1. Description

The uLCD-32PTU module demonstrates class and finesse in the microLCD range, featuring a 3.2” 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.
