hi this I want to send this hex vales but i am getting error.. I am send byte values ,** my error.. constant vales cannot be converted to byte.**
class constant(){
public const byte MESSAGE_START = 0x1020; // command hex
}
public override IEnumerable<byte> ToBytes()
{
yield return constant.MESSAGE_START ;
}
HI, there is another twist i am facing, though with your help I passed the hex value, I should decimal equivalent when i pass through the below method, but value I get is 16.
protected override void TransmitCommand(Device device, Command command) { int count = 0;
foreach (var b in command.ToBytes())
transmitBuffer[count++] = b; // values i get is 16 but not decimal values 4128
}
As I said in the comment, the value MESSAGE_START is a short not a byte. Try this
class constant() {
public const short MESSAGE_START = 0x1020; // command hex
}
public override IEnumerable<byte> ToBytes()
{
yield return (byte) (constant.MESSAGE_START >> 8);
yield return (byte) (constant.MESSAGE_START & 0xff);
}
The above code assumes that the byte representation of the value is in network byte order (most significant byte first). For LSB do
public override IEnumerable<byte> ToBytes()
{
yield return (byte) (constant.MESSAGE_START & 0xFF);
yield return (byte) (constant.MESSAGE_START >> 8);
}
