  • There is a part I want to describe in binary, and when I describe it in an expression such as 0b0101, it does not compile.
    How should I describe it in binary notation?
    • Binary notation is not supported.
      Please prepare the following macros and substitute them.
      Macro definition example:
      #define BIT8 (b7, b6, b5, b4, b3, b2, b1, b0) \\
      ((b7 << 7) | (b6 << 6) | (b5 << 5) | (b4 << 4) | (b3 << 3) | (b2 << 2) | (b1 << 1) | b0)
      #define BIT16 (b15, b14, b13, b12, b11, b10, b9, b8, b7, b6, b5, b4, b3, b2, b1, b0) \\
      ((BIT8 (b15, b14, b13, b12, b11, b10, b9, b8) << 8) | \\
      BIT8 (b7, b6, b5, b4, b3, b2, b1, b0))
      Example of use:
      var8 = BIT8 (0,1,1,1, 0,1,0,1); / * = 0x75 * /
      var16 = BIT16 (0,0,0,0, 0,0,0,1, 0,0,1,0, 0,0,1,1); / * = 0x123 * /
