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

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


ST7565 st7565(p11, p13, p21, p22, p23); // mosi, sclk, cs, rst, a0

//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();
