Binary number

How can a Binary number be used in a program?

  • he's got the same "... = 85" but this time it's B8(01010101), which is correct.

    Hmmm. I always thought 01010101 was 0x55. :-)

  • "Looks like Mr. Torfs has a typo."

    I should have added that the typo is only in his commentary. As far as I know, the macros themselves are fine to use as-is (as-are?).

  • "I always thought 01010101 was 0x55."

    You're closer than I was. Taking 01010101 by itself, I came up with 266305.

  • if You absolutotally HAVE to do it

    #define bin00000001 0x01
    ...
    define bin11111111 0xff

    I do some 'binary' definitions this way

    in my .h file

    sfr S0_TMR2CN           = 0xc8;    // TIMER 2 CONTROL                              */
    sfr S1_TMR3CN           = 0xc8;    // TIMER 3 CONTROL
    sfr S2_TMR4CN           = 0xc8;    // TIMER 4 CONTROL
      sbit SB0_TMR2CN_TF      = 0xcf;
      sbit SB1_TMR3CN_TF      = 0xcf;
      sbit SB1_TMR3CN_TR      = 0xca;
      #define SM_TMRxCN_TF      0x80  // oflo/int
      #define SM_TMRxCN_EXF     0x40  // ext activate
      #define SM_TMRxCN_EXEN    0x08  // ext stimuli
      #define SM_TMRxCN_TR      0x04  // run control
      #define SM_TMRxCN_C_T     0x02  // 1 = counter 0=timer
      #define SM_TMRxCN_CP_RL   0x01  // 0 = reload, 1 = capture
    


    then in the .c file

    //S0_TMR2CN = 0 + SM_TMRxCN_TF + SM_TMRxCN_EXF + SM_TMRxCN_EXEN + SM_TMRxCN_TR + SM_TMRxCN_C_T + SM_TMRxCN_CP_RL;
      S2_TMR4CN = 0                                                 + SM_TMRxCN_TR                 + SM_TMRxCN_CP_RL;
