This is test library which translated from code for arduino. Original code, and their product can be found in the link below. http://www.adafruit.com/products/250

ST7565 LCD

!This is the test library.!

I translated arduino code to mbed. You can find the product and datasheet from the following link.

http://www.adafruit.com/products/250

void begin(uint8_t contrast);

  • Initialize data with Adafruit Logo.
  • contrast is needed

void clear_display(void);

  • Clears only display data. RAM data kept remained.

void clear();

  • Clears display data and RAM data.

void display();

  • Update display with RAM data.

void setpixel(uint8_t x, uint8_t y, uint8_t color);

  • Set a dot at (x, y)

void fillcircle(uint8_t x0, uint8_t y0, uint8_t r, uint8_t color);

  • Draw a filled circle with its center coordinate (x0, y0) and radius r.

void fillrect(uint8_t x, uint8_t y, uint8_t w, uint8_t h, uint8_t color);

  • Draw a filled rectangular with its top-left coordinate (x, y) and its width (w) and height (h).

void drawcircle(uint8_t x0, uint8_t y0, uint8_t r, uint8_t color);

  • Draw a circle with its center coordinate (x0, y0) and radius r.

void drawrect(uint8_t x, uint8_t y, uint8_t w, uint8_t h, uint8_t color);

  • Draw a rectangular with its top-left coordinate (x, y) and its width (w) and height (h).

void drawline(uint8_t x0, uint8_t y0, uint8_t x1, uint8_t y1, uint8_t color);

  • Draw a line starts from (x0, y0) to (x1, y1)

void drawchar(uint8_t x, uint8_t line, char c);

  • Set a character

void drawstring(uint8_t x, uint8_t line, char *c);

  • Set string

Example code for main.cpp:

#include "mbed.h"
#include "st7565LCD.h"


ST7565 st7565(p11, p13, p21, p22, p23); // mosi, sclk, cs, rst, a0
int main()
{
//0x18 defines cntrast
    st7565.begin(0x18);
//show initial data (Adafruit logo)
    st7565.display();
    wait(1.0);
//Clear all data
    st7565.clear();
//test code
        st7565.drawstring(1,1,"test");
//update RAM data
        st7565.display();
    while(1) {
    }
}
