Hi, Just finished by 18f USB board with RS-232 and a 44780 LCD, the board has a 20MHZ osc, but using the internal PLL to get a target clock of 48 MHz. During debugging of the board to get the LCD to work, I noticed that the enable pulse is out of spec, looking in the lcd_hd44780_4 file, I saw there is just one NOP
asm nop -- delay (> 400 ns) In the end there was another problem with the board, so when I reverted back to the original lcd_hd44780_4 file it did work, but probably it is better to replace it with a delay_1us(), so it will work by design and not by accident.
