SoftwareSerial Library - Arduino
The SoftwareSerial library allows serial communication on other digital pins of an Arduino board, using software to replicate the functionality (hence the name "SoftwareSerial"). It is possible to have multiple software serial ports with speeds up to 115200 bps. A parameter enables inverted signaling for devices which require that protocol.
serial - How can I stop SoftwareSerial from receiving data and re ...
2014年10月9日 · I am using Software Serial to read the RFID device data. After I scan something, the Arduino tries to send the value that was read to the web service. This obviously causes a delay and the program only continues execution (i.e. next iteration of the loop() function) after the data has been sent.
