hello
I have actual data I want to send to PC via RS232
to read with Matlab
for example:
/ / Convert the string to bytes is:
byte [] buffer = Encoding.UTF8.GetBytes (counter_string);
but
is that there is a command in C sharp to converte real number to type bytes ?
thanks
Hi Riad1986,
This is a proc i use to send strings:
static void RS232_Write(string _line)
{
if (RS232_On == 1 && RS232_Err == 0)
{
try
{
byte[] _output = new byte[_line.Length + 1];
//loop door alle tekens
for (int Counter = 0; Counter < _line.Length; ++Counter)
{
_output[Counter] = (byte)_line[Counter];
}
//toevoegen end marker
_output[_line.Length] = (byte)RS232_Endbyte;
//and write
RS232.Write(_output, 0, _output.Length);
}
catch
{
Debug.Print("***** RS232 Write Error ");
}
}
}
hello,
and thank you for the help
after the syntax of the program output that are sent are of type Byte.
can I send data de type Real (float)?
I used the following the syntax program:
using System.IO.Ports;
using System.Text;
using System.Threading;
namespace change_this_to_your_namespace
{
public class Program
{
public static void Main()
{
SerialPort UART = new SerialPort(“COM1”, 115200);
int counter = 0;
UART.Open();
while (true)
{
// create a string
string counter_string = “Count: " + counter.ToString() +
”\r\n";
// convert the string to bytes
byte[] buffer = Encoding.UTF8.GetBytes(counter_string);
// send the bytes on the serial port
UART.Write(buffer, 0, buffer.Length);
// increment the counter;
counter++;
//wait…
Thread.Sleep(100);
}
}
}
}

@ riad1986 -
Not math wiz but I would use…
Microsoft sample for you to look at
http://msdn.microsoft.com/en-us/library/c309e6c9(v=vs.110).aspx
Sorry but link is bad…
Microsoft code
public void ConvertDoubleString(double doubleVal) {
string stringVal;
// A conversion from Double to string cannot overflow.
stringVal = System.Convert.ToString(doubleVal);
System.Console.WriteLine("{0} as a string is: {1}",
doubleVal, stringVal);
try {
doubleVal = System.Convert.ToDouble(stringVal);
System.Console.WriteLine("{0} as a double is: {1}",
stringVal, doubleVal);
}
catch (System.OverflowException) {
System.Console.WriteLine(
"Conversion from string-to-double overflowed.");
}
catch (System.FormatException) {
System.Console.WriteLine(
"The string was not formatted as a double.");
}
catch (System.ArgumentException) {
System.Console.WriteLine(
"The string pointed to null.");
}
}
I think you really wanted this?

@ riad1986 - To format code, select the code and then press the 101/010 above the message box.
If you are on the Primium hardware you can use this method:
public static void InsertValueIntoArray(
float f,
byte[] buffer,
int offset
)
