Hi,

I'm trainning unsucessfully to set up the uart1 at 19200 bps using timer1 / 40MHz clk. I've changed all stuff on the mcu getting just a high level output on P1_3. What would be missing in set-up code ??

uPSD looks like running well for I/O port's working routines.

P1SFS0 = 0x0C;

SCON = 0x70;

SCON1 = 0x70;

T2CON = 0xC0;

TMOD = 0x22;

PCON = 0x40;

IE = 0x00;

IEA = 0x12;

IP = 0x00;

IPA = 0x00;

TI1 = 1;

ET1 = 1;

PT1 = 1;

TH1 = 0xF5;

TCON = 0x40;

any help would be appreciate,

thanks in advance,

ic

sorry friends, it just works and nice !! the problem was in a secundary file invoking by the compiler changing WDKEY value.
