How do you know that the lcd is HD44780? I followed the instructions at: fab.cba.mit.edu/.../44780.pdf page 40 In the code i'v changed the following(Which need to display "H"): dataTransmit = "\x30\x0E\x06\x248"; size = 4; but still get no answer and the screen of the lcd is turned off and when i set the stop bit it turns on maybe i need some delay between characters?
