Then, you can write a Python program that does the exact thing you’ve already tested.
Figure out what settings (baud rate etc) you need, what exactly you have to send, and what exactly you can expect to get back. What I like to do when I’m writing a program to communicate with a serial device is to first of all talk to the device by hand with a terminal program (I used to use something called TeraTerm on Windows, that always worked well). Learn how to connect your boards together, setup software, and write code. device transfer learning, and others, check out our example projects. Raspberry Pi Arduino Serial communication - with complete Python code example. Maybe the device is responding, but it isn’t ending its response with a line feed. Python API or use the TensorFlow Lite C++ API.(I notice you’re not sending any sort of new line character) Maybe the device does not respond when you send just the byte b'S'.Maybe you’re not sending the byte b'S' correctly, or using the wrong serial port settings. and then initialising the com ports by including the following code: ser serial.Serial(COM3,9600) - Note the com port and baud rate will be setup to match.Now let’s think about what’s going wrong. (Though it looks like your indentation got messed up during copy and pasting somewhere for the last two lines!) In principle, it looks like the writing should work, though you could just write ser.write(b'S')
