Text Output Functions

Text Output Functions

     All the text output functions have two forms, one where
     you directly specifying the video memory address, and another
     one where you specify x/y coordinates (in character unit).
     The second form is a bit slower but more user-friendly.

put_digit

void put_digit(char digit, int vaddr);
void put_digit(char digit, char x, char y);
Output a digit character '0'-'9' given its numeric value. Hexa digits ('A'-'F') are also supported, a value of 10 will output 'A', a value of 11 will output 'B', and so on.

put_char

void put_char(char c, int vaddr);
void put_char(char c, char x, char y);
Output an ASCII character.

put_raw

void put_raw(int bat_val, int vaddr);
void put_raw(int bat_val, char x, char y);
Output a raw bat-value.

put_number

void put_number(int number, char width, int vaddr);
void put_number(int number, char width, char x, char y);
Output a signed number. The 'width' argument is used to format the number. As much as 'width' digit(s) will be displayed. If the number has less than 'width' digit(s), blank spaces will be added at its left. If the number is negative, a '-' sign is added.

put_hex

void put_hex(int number, char width, int vaddr);
void put_hex(int number, char width, char x, char y);
Output an hexadecimal number.

put_string

void put_string(char *string, int vaddr);
void put_string(char *string, char x, char y);
Output a null terminated ASCII string.
