Saelig Company, Inc. announced that its uLCD-32PT, a 3.2" QVGA LCD display, now features an integrated 4-wire resistive touch-panel touch screen and graphics processor. With a resolution of 240 x 320 pixel, the 65k color TFT  panel features a 5-pin connection to interface to the host device. It also supports external SD/µSD memory cards for storing images, video clips, fonts and general purpose data logging. Additionally, the module includes a dedicated PWM audio pin that supports FAT16 audio WAV files and sound generation, an on-board audio amplifier and speaker, 2 x 30 pin headers for I/O expansion, 4.0V to 5.0V range operation and support for all available Windows fonts and characters.

Two versions of uLCD-32PT are available: uLCD-32PT(GFX) for standalone applications, and uLCD-32PT(SGC) for serial-driven, microprocessor-based devices, allowing the display module. The PICASO-GFX2 chip embedded in the uLCD-32PT(GFX) display allows users to write applications using 4DGL, the high level 4D Graphics Language, which has syntax similar to BASIC, C and Pascal. The (GFX) includes 15K bytes of flash memory for user code storage and 14K bytes of SRAM for user variables, 13 GPIO pins as well as a master I2C interface and 8 x 16 bit timers with 1 millisecond resolution.
