LED Matrix (Parallel) component
LED Matrix component designed to work using multiple data pins and a single clock pin. Each LED on the display can be controlled in a chain by setting the data appropriatley and then generating the appropriate amount of clock pulses.

Detailed description
No detailed description exists yet for this component
Examples
Parallel LED matrix example schematic showing 16 LEDs connected using two octal buffer ICs. Data connections to the microcontroller are Data0-Data7, LED_EN, Reset and Clock.
Each clock pulse transfers the output state to the next LED so Data0 goes to LED R0D0 and LED R0D0 goes to LED R1D0 etc.
Example Program
ledmatrixp
Note. to allow the simulation to run smoothly ensure that the simulation speed is set to normal and you may also want to enable hardware acceleration using the Global Options.
