Parameter	Description
value	byte that should be sent

The value paramter is a single byte which should be transmitted.

Parameter	Description
source	bytes that should be sent
offs	offset to the first data byte
count	number of the data byte

The source parameter is a byte array which should be transferred. The number of data bytes must be specified by the count parameter. The offs paramter specifies the offset to the first byte in the source byte array.

Parameter	Description
source	String that should be sent

The source parameter is a string which should be transmitted.

• The bytes passed by write method are stored temporarily in a TX buffer.
• A TX buffer overflow occurs only when a previously stored and not transmitted byte has been overwritten.
• The methods in this class count the overridden bytes and return the count value in case of a TX buffer overflow.
• The bytes are taken from the TX buffer in case of an data transfer.
• A data transfer is initiated after the byte array is written into the TX buffer.

Example

   uart.write("text message");

The code above writes one whole text message over the UART port.
