![]() I removed the kext and pkg files for the FTDI drivers and deleted them completely, still when I open the System Report I still see the FTDI USB Serial Driver entry. Downloading and installing Arduino on a Mac Step 1: Get all the needed equipment in place. Now even after doing all this when I connect my Arduino Uno to my Mac via the USB it does not get detected. So I removed the FTDI drivers from my Mac so it will use Apple's drivers. He suggested we remove the FTDI drivers and rely on Apple's drivers. Then I came across this post: where the user is having this same problem with MacOS Sierra. I followed this link : where it tells us to download and install the FTDI drivers separately. I updated my OS to Sierra 10.12.5 and now suddenly the usb serial option has disappeared. Guilherme Rambo writes about his coding and reverse engineering adventures.Few weeks ago my Arduino Uno (IDE version 1.8.2) detected the USB port and I was able to do some small IOT projects. If you happen to know of a better solution, feel free to reach out on Twitter. I don’t feel particularly good about this, it seems that I should instead be replacing whatever is setting to point to my own version of Python instead, but I don’t have enough knowledge about how the environment works in the Arduino IDE, and being able to flash my projects to the board was more important than learning that. Restart the Arduino IDE and everything should work fine now. ![]() To do that, open ~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.7.4/platform.txt in a text editor, then replace all occurrences of with the path to your own Python install, in the case of HomeBrew on M1, it would be /opt/homebrew/bin. ![]() But since I have installed Python 3 using HomeBrew, I can tweak the package to use that version instead. Upload error: Error: 2 UNKNOWN: uploading error: uploading error: exit status 1įor some reason, the upload tool included with the ESP8266 package seems to include its own version of Python, which for some other reason doesn’t really work in my particular environment. Make sure you have added the ESP8266 URL to “additional boards manager URLs” in the Arduino IDE settings (this works for both the Arduino Pro IDE as well as the regular one): Īfter installing the ESP8266 boards, if you try to upload your sketch to a board, you’re likely going to run into an error: pyserial or esptool directories not found next to this upload.py tool. Genuine Arduino boards use a CDC/ACM interface, and all modern operating systems have those drivers built in. If you have a cheap Chinese clone then you probably want the CG340G drivers (and good luck with those). There hasnt been an FTDI on an Arduino for many years. Use pip3 from the new python3 that’s just been installed to install the pyserial library: pip3 install pyserial If you have a genuine Arduino you dont want the FTDI drivers. Then, use HomeBrew to install Python 3, which is required by the scripts in the ESP support for the Arduino IDE: brew install python3 HomeBrew has recently been updated with support for M1 Macs. The first step is to install HomeBrew, if you don’t have it yet. ![]() I’m just laying out the steps that worked for me, but I am by no means an expert on the subject, so if this doesn’t work for you, it’s very unlikely that I’ll be able to help you out any further. Obligatory disclaimer: this is not a tutorial. It wasn’t hard to figure out a workaround, so I decided to write it here both as a future reference for myself as well as a helpful resource for others. That’s where I hit a problem, because I’ve been using the new M1 MacBook Air as my work computer for a while, but unfortunately the ESP support for the Arduino IDE doesn’t work out of the box. To make things easier for me, I decided to program my boards with the Arduino Pro IDE, which I’m already familiar with, so I had to install the libraries for the ESP8266. I started out with an Arduino board to test things out, but then people reminded me of the ESP32 and ESP8266 microcontrollers, which integrate BLE and WiFi and can run the HomeKit Accessory Protocol (HAP) natively. Recently, I decided it would be a fun side project to turn a cheap air humidifier into a HomeKit accessory. Programming microcontrollers is something I’ve always liked to do, there’s something very satisfying about writing code that controls things in “real life”, instead of just pixels on a screen. (This code took about 14 seconds to compile and load on a slow 2019 Windows machine, 8 seconds on a slow 2014 Macbook Air, 7 seconds on an M1 Mac under.
