// 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 #include "mbed.h" #include "TextLCD.h" TextLCD lcd(p10, p11, p12, p15, p16, p29, p30); DigitalOut led(LED1); int main() { lcd.locate(0,0); for(int i=0; i<80; i++) { lcd._rs = 1; lcd.writeByte('0' + i); } }
