I think interface to hardware we should select low level language (assembly). Not necessarily. A decent 'C' compiler that has been specifically designed for the 8051 will allow you to access hardware perfectly adequately in most cases. The problem in this particular case is that the OP is trying to mimic assembler instructions in 'C', rather than thinking about what is actually required. As Jan has pointed out, the task of receiving bits (from I2C in this case) into a byte requires shifting, not rotating - and the standard 'C' language provides a perfectly good shift operator to do this! http://www.8052.com/forum/read.phtml?id=123729 |
