// Write to all HD44780 TextLCD RAM locations, sford
//
// A quick hack to write to all the display RAM locations
// in an HD44780 display, to identify which location maps
// to which character.
//
// Instructions:
// - Change TextLCD pinout as appropriate so it works
// - Run, and it should fill the screen with characters
// - Identify what characters are at the start of each row
//
// To determine what address each line starts at, you subtract the
// ascii code for '0'(48) from the character at the start of each line
// - see http://www.asciitable.com/
//
// e.g.
// +----------------+
// |0123456789:;<=>?| first char = '0' (48)
// |XYZ.... | first char = 'X' (88)
// +----------------+
//
// So in this case, the RAM offsets are 0 and 40
