i have a 51 code about timer & interrupts
that i would like to ask you .
now i have found a way to solution it.
this is my problem :
TMOD=0X21;
TH0=OXDC;
TL0=0X59;
EA=1;
ET0=1;
TR0=1;
i am try to read 51 mcu book . i understand a little
i would like to write it in CCS C, but i dont know Register that i must use.
How i define it ?
Could you help me ?
ps. In CCS C i use Pic16F877A with 20 MHZ clock.
Thank you very much. |

These are interupts for serial communication. I think..

ET0=1;
TR0=1; |
So you want Pic16F877A with 20 MHZ clock.
What baud do you want serial communication at? ... 9600,N,8,1 |

The 8051 processor is very different from the PIC processor.
You have to choose, PIC or 8051. You can not use a book for one and a compiler for the other. |

With CCS C, you simply write
| Code: | | #use rs232(uart1, baud=9600) |
and use the getc() and putc() or printf() functions. All necessary register settings are provided by built-in function library. |
