Closer to home, the 8051 offers JBC instruction, which is exactly what you would have used if you were coding in assembly language. The question now is, are there any tricks you can play with your C compiler to make it generate JBC when you need it? If you're using the Keil compiler, it looks like the answer is yes. Wow, I did not know about the testbit function! Thanks ...! -a |
