While building the SeaTalk <-> NMEA Bridge it became quite clear that i need a display for debugging, data visulatisation etc.
So i took a display i had here and connected it to the controller board and wrote a mini library to access graphics and text . If you need a library for a SED 1330 Display connected to a AVR Atmega controllervoid GLCD_Init (void); /* Initialize Display Controler */ void GLCD_Reset(void); /* Reset Display Controler. */ void GLCD_ClearText(void); /* Clear Text Screen */ void GLCD_Text(unsigned char x, unsigned char y, unsigned char *myText); void GLCD_Char(unsigned char myChar); int GLCD_PrintChar(char myChar); /* for using STDIO in avr-libc */ void GLCD_ClearGraph(void); /* Clear Graphic Screen */ void GLCD_Pixel (int x,int y, drawmode show); void GLCD_Line (int x1, int y1, int x2, int y2, drawmode show); void GLCD_Circle(int x, int y, int radius, drawmode show); void GLCD_Rectangle (int x1,int y1,int x2,int y2,drawmode show); void GLCD_DegreeLine(int x,int y, int degree, int inner_radius, int outer_radius, drawmode show);
