| // print() function can only set text position on pixels from left, | |
| // top. | |

| //- The process of accepting input with the virtual keyboard, saving | |
| // into or reading from EEPROM is delt with here. | |
| // | |
| //- A workflow for stop the music while displaying image. Trouble | |
| // will happen otherwise. | |
