Hi Arungokul,
i guess i can understand your question. but let me confirm, you are trying to display Hex value of '0x5A' in the LCD dispaly [through ASCII Character]?
If yes, well the following steps might help you [we will take example 0x5A to be displayed in LCD]
- seperate '5' and 'A' from the HEX as 0x05 and 0x0A,
- add 0x30 to 0x05, to result 0x35 [ASCII value of '5'] and send it to LCD
- add 0x37 ot 0x0A, to result 0x41 [ASCII value of 'A'] and send it to LCD.
Well you have to implement this logic in the Assembly or C.
Hope this helped you, Better luck
