To convert a character received from serial communication to an array with each bit in a separate slot, you can use bitwise operations.
- **Masking:** The simplest approach is to mask the received data using the bitwise
AND
operator. This will allow you to extract individual bits from the character. - **Mapping to an
enum
:** Alternatively, you can define a customenum
with flags corresponding to each bit position. By casting the received character to thisenum
, you can easily access the individual bits.
byte data = (byte)char.Parse(serial.ReadExisting());
this.lstOntvang.Invoke(new MethodInvoker(delegate() {
lstOntvang.Items.Add(data);
if ((data & 1) != 0) lblV10.ForeColor = Color.Red;
else lblV10.ForeColor = Color.Black;
if ((data & 2) != 0) lblV50.ForeColor = Color.Orange;
else lblV50.ForeColor = Color.Black;
if ((data & 4) != 0) lblV90.ForeColor = Color.Green;
else lblV90.ForeColor = Color.Black;
if ((data & 8) != 0) lblVbak.ForeColor = Color.Green;
else lblVbak.ForeColor = Color.Red;
if ((data & 16) != 0) lblW10.ForeColor = Color.Red;
else lblW10.ForeColor = Color.Black;
if ((data & 32) != 0) lblW50.ForeColor = Color.Orange;
else lblW50.ForeColor = Color.Black;
if ((data & 64) != 0) lblW90.ForeColor = Color.Green;
else lblW90.ForeColor = Color.Black;
if ((data & 128) != 0) lblWbak.ForeColor = Color.Green;
else lblWbak.ForeColor = Color.Red;
}));
Mapping to an
enum
Approach:
Define a custom enum
:
/// <summary>
/// Usage: LabelName setLabels = (LabelName) byteValue.
/// </summary>
[Flags]
enum LabelName : byte
{
lblV10 = 0x01,
lblV50 = 0x02,
lblV90 = 0x04,
lblVBak = 0x08,
lblW10 = 0x10,
lblW50 = 0x20,
lblW90 = 0x40,
lblWbak = 0x80,
}
Then, you can use this enum
to convert the received character:
LabelName flags = (LabelName)serial.ReadExisting();
Additional Enhancements:
- If you want to apply custom styling based on the extracted bits, you can use custom attributes to associate each
enum
value with a background color or other visual properties. - You can also add error handling to ensure that the received character is a valid value and handle any potential exceptions.
- Depending on your specific application, you may need to perform additional processing or filtering on the extracted bits before using them.
