    Spent 2 days trying to get the silicon labs CP210x driver working in High Sierra, finally decided Id upgrade from High Sierra to Catalina, and still no go. Have tried everything. I give up! Its going in the trash bin! UPDATE: I had another device fail to work, even on a windows machine. After digging thru my entire cable box, I had tried 4 different USB cables. Turns out all of them were POWER ONLY except one. When I found one that was a REAL usb cable, I was able to connect and upload to the device on both my mac and windows box. One thing I found for Catalina: If you get port in use errors, go to /System/Library/Extensions and sudo kextunload /Library/Extensions/SiLabsUSBDriver.kext/ or any other USB driver you have in there. Catalina includes the driver so youll want to uninstall any other CH340 driver if you have problems connecting to the port.

Description:
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained networking solution, allowing it to either host the application or to offload from another application processor.

 Instruction & Steps of How to use:
1. Download the Arduino IDE, the latest version.
2. Install the IDE
3. Set up your Arduino IDE as: Go to File->Preferences and copy the URL below to get the ESP board manager extensions: arduino.esp8266.com/stable/package_esp8266com_index.json
4. Go to Tools > Board > Board Manager> Type "esp8266" and download the Community esp8266 and install.
5. Set up your chip as: Tools -> Board -> NodeMCU 1.0 (ESP-12E Module) Tools -> Flash Size -> 4M (3M SPIFFS) Tools -> CPU Frequency -> 80 Mhz Tools -> Upload Speed -> 921600 Tools-->Port--> (whatever it is)
6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github) github.com/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release
7. In Arduino IDE, look for the old fashioned Blink program. Load, compile and upload. 8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking.
