#101142 - get it going with a PC at one end that g Responding to: ???'s previous message |
get it going with a PC at one end that gives you a chance to see what is happening. I have no idea if SDCChas a simulator, if so use it.
ES=0; //disable serial port interrupt TI=0; //clears TI resetting to the power up state. If you worry, use IP = 0; I would just delete this confusing infprnmation. TH1=0xFD; //19200 Bds TL1=0xFD; //19200 Bds "19200" Bds Could be, who knows DO note, that when you set SM2, NOTHING will happen unless a 9 bit byte with bit 9 set comes down the pipe. I do not know your derivative (will not use Atmel) bot many derivatives have address match registers, if yours fo, make sure that is set right. Erik |
