B4R Tutorial [Tool]LCD Char maker

Hi,

LCD Char Maker Tool.

1583839289413.png


Functionality
  • Create custom LCD character with 5 pixel horizontal (cols), 8 pixel vertical (rows).
    Each row is represented by a byte with 5 bits.
  • Save / open the character to / from a textfile located in the application folder.
  • Import 8 bytes array string in format 0xNN,0xNN... where NN is HEX value.
  • Create B4R Inline C code (binary string) with copy to clipboard option.
  • Create B4J code (hex string) with copy to clipboard option.
  • Added few example chars in the project objects folder.
Download the B4J source code here.

Notes
  • Tool based on the LCD Char Maker tool I wrote for TinkerForge.
  • Tool supports LCD display connected to Raspberry Pi - using HEX strings (B4J)
  • In below screenshot can also write shorter:
    Dim degreec(8) As Byte = Array As Byte(...)
