Hi everyone,

Device: AT89s8252, Compiler: Keil uVision

CODE:

<pre> #include <reg52.h>
<pre> #include <stdio.h>

<pre> void main (void)
<pre> {
<pre> /*
<pre> SCON = 0x50;
<pre> TMOD |= 0x22;
<pre> TH1 = 0xf5;
<pre> TR1 = 1;
<pre> TI = 1;
<pre> */
<pre>
<pre> SCON = 0x50;
<pre> T2CON= 0x34;
<pre> TH2=0xFe;
<pre> TL2=0xa5;
<pre> RCAP2H=0xfe;
<pre> RCAP2L=0xa5;
<pre> TR2 = 1;

<pre> while(1) putchar("A");
<pre> }

So, using timer1 as baud rate generator forks fine, but when i switch to timer2 (settings are from Atmel example code, seem to be OK) nothing appears on Tx pin?

Thanks!
