serial write buffer
There is an internal 64 byte serial transmit buffer that is filled by Serial.write(). That buffer is empted by sending the data a byte at a time using ...,Serial.write() writes binary data to the serial port. This data is sent as a byte or series of bytes for example: Serial.write(buf, len) where: ,The problem comes in that I thought Serial.write would return almost instantly as long as the buffer had enough room for what was being sent. ,In my project, I need to regularly write to my computer's serial port from the arduino, and I need to do that at a constant frequency. However ... ,The manual says. Serial.write(buf, len) buf: an array to send as a series of bytes len: the length of the buffer. Anyone care to enlighten me , As of Arduino IDE 1.0, serial transmission is asynchronous. If there is enough empty space in the transmit buffer, Serial.write() will return before ..., So your receive buffer could well end up being the end of one set of data and then the start of the next e.g. 3,4,1,2. If all you are sending is the ...,Is it possible to write the data to the serial port like this? Since there is no delay, will this overflow the buffer? Because, sometimes I get the data ... ,write(). Description. Writes binary data to the serial port. This data is sent as a ... len: the length of the buffer ...
