SMART GPU 2 3.5” TOUCH Command Set Smart GPU 2: Intelligent Embedded Graphics, Audio and Touchscreen Processor. Description: The Smart GPU 2 is a powerful easy to use, intellectual property, embedded graphics, audio and touchscreen processor in a state-ofthe-art ARM Cortex-M3 chip; this is mounted on a board with a touchscreen color LCD. It's aimed to help developers to create advanced Graphical User Interfaces (GUIs) in a very easy way.

SMART GPU 2 3.5” TOUCH Command Set The next image clearly explains the roles played by the user host main processor and the Smart GPU 2 processor: Instead of loading all the Geometry, Images, audio, video, SD FAT memory access, etc. processing to the main host processor, the Smart GPU 2 does the entire job and stuff in parallel with the user microcontroller/microprocessor by receiving simple orders or commands.

SMART GPU 2 3.5” TOUCH Command Set 1.-Host Interface The Smart GPU 2 is a slave peripheral device and it provides a bidirectional serial interface to a host controller via its USART(Universal Serial Asynchronous Receiver - Transmitter). Any microcontroller or processor (AVR, PIC, BASICstamp, XXDUINO, raspberry PI, 8051, MBED, FPGA, ARM, STmicro, etc) or PC(by serial interface RS232) as host, can communicate to the device over this serial interface from 9600bps up to 2000000bps.
PAGE 12
SMART GPU 2 3.5” TOUCH Command Set 1.2 Serial Set-up The Smart GPU 2 is configured to be always initialized at a standard baud rate of 9600 bps. So the first command that the host sends to the Smart GPU 2 must be at that speed. Always after any power-up or reset, the Smart GPU 2 must be initialized by sending the uppercase ascii character ‘U’ (55hex) at 9600bps. This will initialize all the processor, and when done it will respond with an ACK byte (4Fhex, ‘O’ascii).
PAGE 13
SMART GPU 2 3.5” TOUCH Command Set 1.4 Splash Screen on Power Up The Smart GPU 2 will wait up to 3 seconds with its screen in black, for the host to transmit the Initial command (‘U’, 55hex). If the host has not transmitted this initial command the module will display its splash screen. If the host has transmitted only the initial command and has received a valid ACK, the screen will remain in black.

SMART GPU 2 3.5” TOUCH Command Set 2. SMART GPU 2 Command Set - Software Interface Specification 2. Command Set As mentioned before the command interface between the Smart GPU 2 and the host processor is via the serial interface USART/UART. A list of very easy to learn commands provide complete access to all the available functions. Commands and responses can be a single byte or a byte package. All commands always return a response, either a single ACK, or data followed by an ACK.
