Dear all, I want to access some continus bit,let me can modify the value,such as, for(i = 0 ; i < 10 ; i++) { bit[i] = ?; } but you know,the bit var cann't build as a array in keil c51,but build some boolean var with byte will speed down the MCU and more code,Who can give me a good advice and a way,Thanks in advance.
