Hi Friends, i have two problems:
1-i try writting a code in C using atmel 89c52 to simulate spi.does anyone has a helpful code for me?
2-in the program declaration,i declare an array: int Read_Va[]=0x0D; when i try to read it during the program: ACC=Read_Va;
ACC equal A to D why? Thanks
No, I'm afraid you are wrong: you cannot rely upon the compiler not to use the accumulator for its own purposes - therefore, you must not use it for your purposes.
You might be lucky (sic?) and happen to get away with it on this occasion - but, if you continue to rely upon it, you will come unstuck!
