PySerial API - pySerial's documentation, With no timeout it will block until the requested number of bytes is read. Note, for some USB serial adapters, this may only flush the buffer of the OS and not all​ Return type: bytes Read size bytes from the serial port. If a timeout is set it may return less characters as requested. I'm trying to 'ping pong' info back and forth between some python code and arduino code.I want to send two setpoints to the arduino code periodically (for instance on the minute), read them on ard.

Jan-18-2018, 12:05 PM Hello, I'm new in python. I use an Arduino to sensing, and I wrote a small python program to read the data from usb. I use Python 3.5. The program is this: When I execute it, I get only the first sentence repeatedly of what Arduino sends, not the rest of of the calculations. So I suppose I should flush the Serial buffer. When I flush the serial with the command flushInput() as I read from here: http://pyserial.readthedocs.io/en/latest...l_api.html I get: flushInput() NameError: name 'flushInput' is not defined Jan-18-2018, 12:48 PM Hello and welcome to Python and our forums! There seems to be a little change in API, see if this will fix your error: http://pyserial.readthedocs.io/en/latest...put_buffer Jan-18-2018, 02:21 PM (This post was last modified: Jan-18-2018, 02:21 PM by python_beginner.) Thank you, I changed the command, but I still get: I cannot understand! I import serial and time. What is wrong? Jan-18-2018, 03:15 PM You need to do reset_input_buffer() is a method of Serial class.

If you want to read more lines, do the reading inside the while loop. Jan-19-2018, 11:13 AM Thank you both your help. It works now. But it prints Escape characters with the data. Is there a way to avoid that? |
