SUBTEAM 1

Video Subsystem

Specifications:

Input: [internal] Input interface (40 pins?) to be used as input by the main control subsystem (micro-controller o processor)

Provide specification for this input interface. 8 bits per RGB color (Red-Green-Blue) plus 12 bit per axis (X-Y)

Input: [internal] Power lines (VDD, Ground) Input: [external] [shared] Hard-reset button Input: [Internal] JTAG to program microprocessor/controller

Output [external]: VGA port (A female DE-15 connector output) Output: [external] [optional] DVI port (A female DVI connector output) Construction and testing: using breadboard

Circuit diagram: using PSpice Early assessment of needed components: microprocessor/controller (pic* type?), and

socket, digital to analog convertor (DAC), clock, memory chips, capacitors (?), resistors (?), transistors (?), DIPs, ....

Considerations: Resolution settings (refresh frequency, horizontal resolution, ...), use another board with a JTAG to program microprocessor/controller
