The VGA interface for any application
The uVGA-III is a compact and cost-effective VGA Graphics Engine packed with features. It is ready to become the GUI for your target application and can also serve as an interface controller for several other applications.
The PICASO processor is embedded at the heart of the design, driven by a highly optimised virtual core engine called EVE (Extensible Virtual Engine). The design integrates an extensive range of hardware and software peripherals, allowing users to adapt the module to suit almost any application.
The module combines a display driver capable of 320×240 (QVGA), 640×480 (VGA), and 800×480 (WVGA) resolution output to a standard VGA display, a micro-SD card connector, along with a group of general-purpose input/output pins (GPIOs), including I2C and serial UART communications.
This module is a perfect solution for connecting to an external VGA monitor for an application requiring animation, slideshows, images, or sound. This PICASO-driven Intelligent Display Module perfectly exemplifies where art meets technology.
Audio support on the display module is supplied by the PICASO processor, which outputs a line-level audio signal ready to drive an external amplifier of choice. Simple instructions enable the user to play audio files while continuing the execution of the user application code, such as display updates, communications, and much more.
The micro-SD card slot provides the user with expandable memory space for retrieving multimedia files, including images, animations, movie clips, and data-logging applications.
The module can be programmed as a master or slave device using the Workshop 4 IDE Software. It can also be configured as a serial slave with your favourite Host Controller. With the intelligent uVGA-III VGA Graphics Engine module, freedom is at your fingertips.
