microVGA – VGA GRAPHICS ENGINE 4D SYSTEMS µVGA-III 4. Hardware Interface - Pins The μVGA-III provides both a hardware and software interface. This section describes in detail the hardware interface pins of the device. 4.1. Serial Ports - COM0, COM1 UARTS The μVGA-III has two dedicated hardware Asynchronous Serial UART ports that can communicate with external serial devices. These are referred to as the COM0 and the COM1 serial ports.
microVGA – VGA GRAPHICS ENGINE 4D SYSTEMS µVGA-III IO5/BUS_WR pin (GPIO IO5 or BUS_WR pin): General Purpose IO5 pin. Also used for BUS_WR signal to write and latch the data to the parallel GPIO BUS0..BUS7. BUS0-BUS7 pins (GPIO 8-Bit Bus): 8-bit parallel General purpose I/O Bus. 4.4. VGA Output Header and Pads The μVGA-III features a remote VGA connector, which is able to be disconnected from the PCB. The remote VGA connector enables flexible mounting and connection options when using the μVGA-III.

Audio Audio playback support in the PICASO Processor enables the μVGA-III module to play WAV audio at Line Levels to a pin on the expansion header. A simple instruction enables the user to play/pause/stop audio files while continuing the execution of the users code, such as display updates, touch recognition, communications, etc. The audio system also allows real time pitch change of audio samples.
