delay(1000); } arduino方面,前三个数据将在0-255之间。接下来的4个数据将是浮点数,最后一个数据将是整数。这是来自传感器的数据,我敢肯定。 在python方面,它是这样的: import serial com = serial.Serial('/dev/ttyUSB0', 9600, timeout=1) com.reset_input_buffer() while True : sensorData = com....
When using two software serial ports, you have to switch ports by listen()ing on each one in turn. Pick a logical time to switch ports, like the end of an expected transmission, or when the buffer is empty. This example switches ports when there is nothing ...
So every 104.16us, a bit is sent from the buffer until it is empty. Similarly, the receiver looks for data bits separated in time by 104.16us.Arduino Serial Begin: Why 9600Baud?The serial hardware module in the Arduino (or USART - Universal Synchronous Asynchronous Receiver Transmitter) was ...
