Detailed Description

ID: lol
Name: Lots of LEDs (LoL) Array Rev A
Category: display
Manufacturer: adafruit
Connection: gpio

This module defines the LoL API and implementation for a simple framebuffer.

int
main(int argc, char** argv)
{
    upm::LoL sensor;
    signal(SIGINT, sig_handler);
    // buffer = sensor.getFramebuffer();
    int x = 0, y = 0;
    while (!is_running) {
        sensor.setPixel(x, y, !(sensor.getPixel(x, y)));
        if (++x == 13) {
            x = 0;
            y++;
        }
        if (y == 9)
            y = 0;
        upm_delay_us(10000);
    }
    std::cout << "exiting application" << std::endl;
    return 0;
}

unsigned char * getFramebuffer ( )

Gets a framebuffer pointer

Returns: 0 if successful

bool getPixel	(	int	x,

	)

Gets a pixel at specified coordinates

Parameters

x	Coordinate x
y	Coordinate y

Returns: true if the pixel is on, false if off

Exceptions
