Is it required download Port for programming microcontrollers(eg.ESP32)on Mac?
Or if it so then how to do that?
Try to program ESP32, but stuck while selecting the port no.

I'm coding C/C++ on an Arduino to communicate with a Node.js server over the serial port using the serialport Node.js package. I have written this code on a Mac. In my Node.js code I need to reference the USB port, for reference mine is:
/dev/tty.wchusbserialfa14
On a Mac, to get a list of ports in a format that will work in my Node.js code I use the terminal and this command:
ls /dev/{tty,cu}.*
I can not find the equivalent for a Windows computer. Could someone please tell me what the command is to list the ports on a Windows machine, in a format that I can use in my Node.js.
Thanks!
Edit: Added more context about use of ports
You are searching not USB ports, but serial ports. Because you are using USB to serial converter that build in Arduino, and looking about serial ports. How to get list of serial ports in windows you can find here or in google.
Excuse me, can't comment yet.
Thanks for your help! The following command gave me a list of ports in a format that will work in my Node.js code:

I'm new to programming Arduino boards. I have an Arduino Leonardo with Headers and I'm trying to upload a program to it. I've been getting this error:
avrdude: error: programmer did not respond to command: exit bootloader
Here's my Build Options:
I'm assuming my Port or Programmer isn't configured correctly. What should the Port and Programmer be? Do I need to install a driver?
Port
You should select port of serial communication with your board. It should look like this (I have connected Arduino UNO):
Programmer
In regular case programmer selection is irelevant. Arduino IDE uses programmer only if you want it. So if you want to upload your code with usb cable, you do not need to care about it.
Drivers
If you are sure, that your cable is working and Arduino port is not in the list of ports in Arduino IDE, you should install FTDI drivers. To install
Head over to the FTDI Chip drivers page
Scroll down a little to find the table of download links. Find your computer operating system in the list and select the appropriate download link
Download the driver to your computer
Open the installer DMG file
Open the FTDIUSBSerial.pkg file. This will open an installer dialog box. Click continue through the main windows, and agree to terms of software license agreement to install
Enter your admin password. Click Install Software. Wait while install processes. Installation should be successful.
Thanks to Jan Černý for the detailed response.
The actual solution to my problem however was getting the right cable. I was using a micro usb cable that must have been charge only.
Anyway, I bought one of these and the correct Port showed up.
I'm trying to read temperatures into NodeJS (or command-line program) app on Windows with DS18B20 thermometers connected to serial port.
There are some apps, but I can't use them (Digitemp - no support for Windows, Logtemp - it doesn't communicate with NodeJS.
Is there any possible way to read temperatures directly in NodeJS from serial port or from command-line program?
There are lots of tutorials and libraries for Arduino, but nothing for this issue.
Thanks
I am trying to open USB port in Python (using pySerial). I ran port listing tool, but it only shows COM ports. I'd like to open USB port instead (trying to communicate with tablet, but that's not relevant, I suppose). I know it is possible (and quite easy) on Linux, but I am on Windows 8, so there's nothing like "/dev/tty...".
I'd like to show you some of my code, but I can't, because I have none yet (I need to know how to open USB port to be able to start coding, I am just testing yet).
Maybe I will have to install some other module, but I'd rather just stay with pySerial, if it's possible.
Can anyone help me with opening USB port?
I've got an Atmel AVR A90USBxxxx device that I have configured to "talk USB" via CDC. It's designed to take input from a Host computer, running Windows, Linux, or OS X.
I'm under the impression that Linux and OS X will immediately recognize this CDC device, and with a simple .inf a Windows machine can be told my VID/PID should be opened as a CDC device using usbser.sys.
My question is once the OS has opened this USB device as a serial device, how can I programmatically read and write to that port (for each of the 3 OS's listed but most detail is needed for Windows as I'm completely unfamiliar there)
Thanks
The answer really depends on what programming language you intend to use. Without knowing what language you intend to use, I can't tell you exactly how to do it, but I can point you in the right direction.
For prototyping, I recommend using Python with the PySerial module. It's very easy to set up and quickly write a functional prototype. Python will run on Windows, Linux, and OS X. That way you only need to write the serial communication code once and you can test on all of your platforms.
The PySerial documentation contains some examples for how to read and write to the port.
If Python doesn't work for you in production, I would still recommend sticking with a programming language that has a cross-platform serial port library if possible.
Here's a question that was asked already about a cross-platform serial port library for C: C: cross-platform RS-232 serial library?
