Theoretically, these Ascii characters ''AbcdEFGHIJKLMnopqrStUvWXYZ1234567890'' can be displayed, but some characters need to be identified according to the following table:






3 Special Function Characters:
#:Reset(And Clear Screen)
*:Insert Decimal Point
%:Bit Clear

How to use:
Connect the DC 5V power supply to the VCC GND port, and connect the RXD port to the TXD port of the MCU or USB to TTL Board

UART communication parameters: Baud rate 9600, 8, 1, N

Add the # reset command in front of the character, you can enter 1-5 characters (1-4 characters and 1 decimal point) at a time, more than 5 characters will cover the previous characters, except for #*% and the characters to be displayed, There must be no other characters (space/enter), otherwise an exception will be displayed.
 
Example:
Display 1234 Input: #1234
Display 123.4 Input: #123*4
Display 88.88 Input: #88*88
Display 123 Input : #123% Do not display the lowest digit
Display 234 Input : #%234 does not display the highest bit

Notice:
If it shows abnormality, please check if the string has ''space/enter'' or other special characters at the beginning or end of the string
