Using PIC to write efficient bit shift operations

Writing Efficient Shift Operations with PIC Shift operations are required in many analog serial communications. Taking the read byte of 1-W bus as an example, the original code is: unsigned char read_byte(void) { unsigned char i; unsigned char value = 0; for (i = 0; i 8; i++) { if(read_bit())
