You can use the Arduino Software (IDE) serial monitor to view the sent data, or it can be read by Processing (see code below), Flash, PD, Max/MSP (see example below), etc. The examples below split the incoming string on the commas and convert the string into numbers again. 可以使用...

Phase encoding has a constant bit length, PULSE_DISTANCE with constant pulse width and PULSE_WIDTH have no constant bit length!A well known example for PULSE_DISTANCE with non constant pulse width encoding is the RS232 serial encoding. Here the non constant pulse width is used to enable a ...
