Binary number

If this is true...

whatever = B8(10101010);

and will translate as:

whatever = 85;

I'm not sure I want to use this code.

10101010 in Binary = 0xAA in Hexadecimal.

Looks like Mr. Torfs has a typo. Further down just above the second of his two(!) signatures in "Sample usage:", 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;
