Sorry I did not write for a while.
No, it did not help.
I tried another methods to send data to LCD, more delays,
trying to send a single letter, “B” which is 0x42, or 01000010, port on the card is on the right data, also port on the lcd is on the right data, but still the display show “C”.
maybe LCD is defective?
