Saelig, Pittsford, NY, has introduced the uLCD-32PT, a 65K thin film transistor liquid crystal display that has a 3.2", 240 × 320 pixel color panel with an integrated 4-wire resistive touchscreen. A 5-pin connection provides an interface to host devices and supports external SD/μSD memory cards for storing images, video clips, fonts, and data logs. Additionally, the module includes a dedicated PWM audio pin that works with FAT16 audio WAV files, an onboard audio amplifier and speaker, 2 × 30 pin headers for I/O expansion, 4.0V to 5.0V range operation, and support for available Windows characters. Two versions are available: one for standalone applications and another for serial-driven, microprocessor-based devices, allowing the display module to be used as a slave device where the external host sends screen-related functions using a serial protocol. The PICASO-GFX2 chip embedded in the uLCD-32PT (GFX) display allows users to write applications with 4DGL.
