Re: [DUG] Access Violation

[Jeremy Coulter]

One thought, maybe do something like:

    If length(sRaw) >0 then

       for i:=1 to length(sRaw) do
          try iData[i]:= byte(sRaw[i])
          except
       end;        

This will only do the for loop if sRaw is not empty. Just a thought. 

I do agree with Paul, Async Pro is very good. I have used it for YEARS and
its very reliable.

If you want to try it out, its on sourceforge now. We actually bought them
before they went open source L

Not sure where to go with this.

 

I'm sending 3 bytes of data  at 38400 baud every 500 ms. If I speed up the
rate to every 250 ms I get   

 

Access Violation at address 004934CA in Mmodule Dyno.exe' Write address
000000F2 

 

Code   

 

    if SerialPortNG.NextClusterSize >= 0 then begin
       sRaw:=SerialPortNG.ReadNextClusterAsString;
       for i:=1 to length(sRaw) do
          try iData[i]:= byte(sRaw[i])
          except
       end;        

 

I don't know what I'm looking for. 

 

Thanks Wallace
