Arduino 1.8.9, Windows 10, updatet, Driver for ESP8266 - CH340 - no ports Having used the Arduino IDE for many years, but apparently today, when I wanted to start a new project, I can't get the Arduino IDE to show the COM ports. I have tried uninstalling my CH340 Driver and reinstalled it. It went fine, but there are still no com ports available. Have tried on another Windows 10 PC which I. Installing NodeMCU driver on MAC. The NodeMCU is using USB 2 Serial Communication called CH340, you can download the driver at the link below, you have to install the driver package as you used the NodeMCU on Mac. After you install the CH340 driver you need to test the serial communication by filtering using a bash command see it below. The objective of this short post is to explain how to get the MAC address of the ESP8266. Explaining in detail what is a MAC address is outside of the scope of this post. But, just as a quick explanation, the MAC address is a unique value associated with a network adapter 1.

1. Install Heltec ESP(ESP32 and ESP8266) development framework:
- GitHub repository: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series
Please refer to the README.md document to clone and install. This project must in ” *:DocumentsArduinohardware ” path.
2. Install Arduino library
- Install Heltec ESP32 Arduino library: https://github.com/HelTecAutomation/Heltec_ESP32
- Install Heltec ESP8266 Arduino library: https://github.com/HelTecAutomation/Heltec_ESP8266
Please refer to the README.md document to clone and install. Arduino library must in ” *:DocumentsArduinolibraries ” path.
A few days ago a package arrived from SeeedStudio: the new NodeMCU board V1.0 (see picture)| The NodeMCU V1.0 (picture from here) |
On paper it has some nice advantages compared to the old V0.9 version or also to other ESP8266 dev boards: you can directly connect it to your computer for programming and you won’t need an additional USB-to-Serial programmer or an external power supply. The USB connector does the job. The only problem: they must have changed something on the interface. Flashing doesn’t work out of the box anymore:

I’m programming on a Mac, so all the fancy Windows based flashing tools won’t work for me directly. I usually use the adapted Arduino IDE or the esptool.py to upload new images to the device. This posts describes how you can flash the new hardware despite the problems with the esptool. Basically it shows how you can use the original Windows tool from Espressif from your Mac OS X system, even if it is made for Windows.
- Download and install driver for the CP2102 from here: https://www.silabs.com/Support%20Documents/Software/Mac_OSX_VCP_Driver.zip
- If you don’t already have it install homebrew: http://brew.sh/
- Install wine:
I had to work around some issues with brew and wine. Write a comment if you want to know how I resolved them…
- Download the latest Flashing tool from Espressif:
http://bbs.espressif.com/viewtopic.php?f=5&t=433 - Install unrar (if you don’t already have it):
- Unpack the flash tool:
- Install unrar (if you don’t already have it):
- Enter the directory and start the Flashing Tool:
- Now that the wine directory has created enter the dosdevices folder and create a symlink to your NodeMCUs tty device:
- Select your image and adjust the settings according to this screenshot:
ESP Flash Tool started from wine: adjust the settings accordingly - Now connect the NodeMCU module using USB and press the RST button while you keep pressing the FLASH button. This will put the module into the right state for flashing
- Now click START in the flasher tool and wait until it is finished. Click RST again and have fun.
I hope that the esptool gets fixed quickly to work with the new hardware. I’m also not sure whether the problems comes from the USB-to-Serial converter or rather from the ESP-12E module. I suspect it is the later, but I couldn’t find anyone complaining about problems with the ESP-12E in general.
