You typically use the sbit data type for P2_0 to define a bit within a special function register (SFR). From C51: READING FROM AN INPUT PORT (modified) sfr P2 = 0xA0; sbit P2_0 = P2^0; ... P2_0 = 1; /* set port for input */ var = P2_0; /* read P2_0 into var */ It is important to note that sbit variables may not be declared inside a function.

SBIT( P0_1 , 0x81 ) /* GPIO - Port 0, Input 1 */ SBIT( P0_0 , 0x80 ) /* GPIO - Port 0, Input 0 */ Can anybody help a learner, C++ seems to have so many different dialects. Replies. Post Information ... I got my books out (again) and realised that the #define just replaces SBIT with the new definition, using the parameters it is passed.
CHECKBIT (PORTX, 4)) {} else {} // result is true if bit4 of portx is 0, false if it is 1 WRITEBIT (PORTX, 0, PORTY, 2); // copy the bit0 of portx to bit2 of porty P.S. the above was an example for AVR where PORTX is the output of the post, depending on the mcu used you will change it to use the proper name of the output.

Hi Andy, Thanks for your quick reply. I actually want that two bits place in the upper nibble (MSB) of a byte. thanks for your good suggestion. regards
#define out P2 sbit pos=P0^0; sbit neg=P0^1;P0这个是单片机里面用的需要用对应的IDE同时引用和你芯片对应的头文件比如c51.h什么的
