Detailed Description

This driver is meant for the monochrome LCD display (model no: LS013B4DN04) from Sharp.

The LCD has the following pixel dimensions: width=96pixels, height=96pixels. This is a monochrome display with an inbuilt memory of 1 bit per pixel. If a pixel-bit is set to one, the corresponding pixel will show as black.

The LCD memory is accessible to the micro-controller only through a serial interface; and only for write operations. It is necessary for the application to maintain its own frame-buffer memory in the micro-controller's SRAM (see fb_alloc())---the application is not restricted to a single framebuffer; if SRAM size permits, multiple buffers may be employed. In order to update the LCD, the application first draws (bitmaps or text) into some framebuffer memory, and then flushes the framebuffer to the LCD over the serial interface.

Here's some sample code to drive the LCD display:

DigitalOut led1(LED1); SharpLCD lcd(p9, MBED_SPI0);

uint8_t framebuffer[SharpLCD::SIZEOF_FRAMEBUFFER_FOR_ALLOC];

int main(void) { SharpLCD::FrameBuffer fb(framebuffer);

lcd.enableDisplay(); lcd.clear(); fb.printString(lookupFontFace("DejaVu Serif", 8), 20, 40, BLACK, "Rohit"); lcd.drawFrameBuffer(fb);

led1 = 1; while (true) { wait(0.5); led1 = !led1; } }
