I just love these micro-readerboards. I started making one in preparation for a soldering project with 3 11 year olds. Now I want to make them for all my friends.
One thing that is interesting is how, if your attention wanders for just a second, you can lose the meaning of what's being displayed. I thought it would be cool to do a little animation to catch people's attention at the beginning. I thought a spinning clock would be cool, so I extended the font. There was already a "/", and by adding "\" "|" and "-" you can do a little spinner.
First add the following to the end of the Font table:
PHP Formatted Code
0x420, //backward slash ('\') character.
0x4008, //Dash('-') character.
0x044
Change or add one of the strings to include the sequence, for example:
PHP Formatted Code
const char StringA[] PROGMEM = "|/-\\|/-\\|/-\\|/-\\|/-\\|/-\\| ";
Then after the lines that read:
PHP Formatted Code
else if (buf[i] == '/')
FontWord = (uint16_t)pgm_read_word(&font_table[27]);
add
PHP Formatted Code
else if (buf[i] == '\\')
FontWord = (uint16_t)pgm_read_word(&font_table[28]);
else if (buf[i] == '-')
FontWord = (uint16_t)pgm_read_word(&font_table[29]);
else if (buf[i] == '|')
FontWord = (uint16_t)pgm_read_word(&font_table[30]);
Minor Font hack (Spinning clock)
