I am working on a project that makes acquisition of signal from a GPS via serial port.I am trying to debug my code following the example of the pdf Getting Stared: MODE COM1 4800,0,8,1 ASSIGN COM1 <S0IN >S0OUT I get the following error: error 30: undefined name of virtual register I cannot understand the reason of the error.Can someone help me, please?
Hi there Amilcar, Not sure I can't understand the specific problem you're having, but I take it that the gyst of what you're getting at is you have a GPS system, and you want to read in its serial output into your microprocessors serial input. If you're trying to get a feel for what comes out of the GPS system (and want to check that you have the serial settings correct) then why not use something like hyperterm on the PC (I know that there are those on this list who don't like it, but it will get you going - personally I've never found it troublesome!). You can then also use hyperterm to send signals to you microprocessor to help commission whatever code you have to read in text over the RS232 setup - note thought that this has been done many times before - you don't necessarily have to reinvent this wheel. Is this of any use? Yours, Richard.
Hi, the registers are sin and sout. mode com1 9600, 0, 8, 1 assign com1 <sin> sout
