Posted on May 17, 2011 at 11:51Dear all, I am Drip.
Now i write code for upsd3434e's IrDA like follow:
first set JP12 4�6 and 3�5, make UART1 work in IrDA
TH2=0xFF;
TL2=0x7E;
RCAP2H=0xFF; // set baud rate 9600bps
RCAP2L=0x7E;
C_T2=0;
TR2=1;
PCON=0x3C;
SCON1=0x50;
P1SFS0|=0x0C;
P1SFS1&=0xF3;
IEA|=0x10;
IPA|=0x10;
IRDACON|=0x40; //IRDAEN=1, enable IRDA
But why IrDA can not work well, i can receive byte send by PDA, but the content is wrong, but the num of receive byte is right. who can tell me why?
I think maybe the baud rate is not the same, IrDA's is 9615, but PDA's is 9600, but i do not sure other is ok.
who can help me ,thank you very much!
:D :D :D
