AsciiFont

This is a library to draw the ASCII font characters.

Example

#include "mbed.h"
#include "AsciiFont.h"

#define WIDTH           (12)
#define HEIGHT          (16)
#define BYTE_PER_PIXEL  (1u)
#define STRIDE          (((WIDTH * BYTE_PER_PIXEL) + 7u) & ~7u) //multiple of 8

uint8_t text_field[STRIDE * HEIGHT];

//for debug
void print_text_field() {
    int idx = 0;

    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < STRIDE; j++) {
            printf("%02x", text_field[idx++]);
        }
        printf("\r\n");
    }
    printf("\r\n");
}

int main() {
    AsciiFont ascii_font(text_field, WIDTH, HEIGHT, STRIDE, BYTE_PER_PIXEL);

    ascii_font.Erase(0xcc);
    ascii_font.DrawStr("AB", 0, 0, 0x11, 1);
    ascii_font.DrawChar('C', AsciiFont::CHAR_PIX_WIDTH,
                        AsciiFont::CHAR_PIX_HEIGHT, 0x22, 1);
    print_text_field(); //debug print

    ascii_font.Erase();
    ascii_font.DrawStr("D", 0, 0, 0xef, 2);
    print_text_field(); //debug print

    ascii_font.Erase(0x11, 6, 0, 6, 8);
    print_text_field(); //debug print
}
