I'm trying to send numbers over the serial port as bytes, not strings.
What I mean is if I want to send a 255, that should be 1 byte, not a 2
followed by a 5 and a 5. I'm trying to convert a borland c++ app.
This is what the c++ app does
int8B = 255;
WriteFile(serialPort,&int8B,1,&bytesWritten,NULL);
int8 = gainSlider->Position;
WriteFile(serialPort,&int8,1,&bytesWritten,NULL);
int8 = offsetSlider->Position;
WriteFile(serialPort,&int8,1,&bytesWritten,NULL);
int8 = exposureSlider->Position;
WriteFile(serialPort,&int8,1,&bytesWritten,NULL);
Here is what I'm doing that does not work
int x = 255;
sp.WriteLine(String.Format("{0}", x));
sp.WriteLine(String.Format("{0}", trackBar_Gain.Value));
sp.WriteLine(String.Format("{0}", trackBar_Offset.Value));
sp.WriteLine(String.Format("{0}", trackBar_Exposure.Value));
How do I send the 255? I can't do sp.WriteLine(255) since it wants a
string.
any help will be greatly appreciated.
