Install FTDI-drivers on Mac OS X 10.10 Yosemite

REMEMBER: This is for OS X 10.10 Yosemite.

If you are going to use the ESP8266 with a FTDI-cable, you first need to install some drivers. Actually this is pretty basic IF you read the manual (link is below), but if you are like me; here are the steps you “need” to follow.

1. First uninstall Apple-provided FTDI VCP driver, from the Terminal.

Type :
cd /Library/Extensions
sudo rm -r FTDIUSBSerialDriver.kext


2. Download VCP-drivers and install, normal .dmg-install. (Even I now how to do this, just follow the wizard).

3. Download D2xx Drivers (1.2.2) copy libftd2xx.1.2.2.dylib (think I used the one in /bin/10.5-10.7) into the dir /usr/local/lib (use Terminal or Finder).

Change dir to /usr/local/lib

Create a symbolic link1 to the library (ln -sf libftd2xx.1.2.2.dylib libftd2xx.dylib)

Done! (Taken from the installation guide @

Next: Test drive your ESP8266 with some basic AT-commands

Bonus (some Terminal stuff). Command ln (linkname) creates links between files. Passing -sf as options:
-s create symbolic link (soft link)
-f (force) overwrite file if it already exist

In the next part we’ll be looking at hooking up the ESP8266 to your computer via the FTDI-cable.

The idiot guide to ESP8266

In the coming days (weeks? months? years?) I’ll be talking about the ESP8266. ESP8266? From

“ESP8266 is a complete and self-contained Wi-Fi network solutions that can carry software applications, or through Another application processor uninstall all Wi-Fi networking capabilities”

I spent some time (more then I’m willing to admit!) reading numerous guides and blogs and so forth about the little fucker!

Pretty new to the world of electronics and microcontrollers (and with a faint mind) the guides never suited my needs so I thought I’ll do a series of guides for myself and other idiots out there!
