UART1

Hi Everybody,

I am using the two UARTs in my aplication. I manage to operate UART0 and partly of UART1, I can send data from UART0 to UART1 but I can't send from UART1 to UART0. I am using timer2 for the baud rate(for both of them). I think that UART1 interrupt service routine is not working when I send data(It works with polling).

My UART1 configuration is:

PCON = 0x3C;

SCON1 =0x50;

P1SFS0 |= 0x0C;

P1SFS1 &= 0xF3;

IPA |= 0x10;

IEA |= 0x10;

Do I miss something? If anyone have good Init of UART1 I will be glad to receive it.

Thanks

KH

That is because you forget to enable UART0 receive. You neeed to add the statement

SCON0 = 0x50; to your program.
