Listing devices on Linux


  • ls – list files in the file system
  • lsblk – list the block devices (i.e. drives)
    • mount| grep /dev/sd – lists mounted partitions
  • lspci – list the pci devices
    • lspci -vv
    • lspci -vvv
  • lsusb – list the USB devices
  • lsdev – list all the devices

List serial ports


Linux uses ttySx for a serial port device name. For example, COM1 (DOS/Windows name) is ttyS0, COM2 is ttyS1 and so on.

  • dmesg |grep tty
  • setserial -g /dev/ttyS[0123]

Using an ESP8266 microchip based Wi-fi module with Arduino



“The ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer Espressif Systems

Arduino core for ESP8266 WiFi chip

brings support for ESP8266 chip to the Arduino environment. It lets you write sketches using familiar Arduino functions and libraries, and run them directly on ESP8266, no external microcontroller required.

ESP8266 Arduino core comes with libraries to communicate over WiFi using TCP and UDP, set up HTTP, mDNS, SSDP, and DNS servers, do OTA updates, use a file system in flash memory, work with SD cards, servos, SPI and I2C peripherals.”

Installing with Boards Manager

Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit).

  • Install the current upstream Arduino IDE at the 1.8 level or later. The current version is at the Arduino website.
  • Start Arduino and open Preferences window.
  • Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
  • Open Boards Manager from Tools > Board menu and install esp8266 platform (and don’t forget to select your ESP8266 board from Tools > Board menu after installation).
