The files have become so large that they might not fit onto all modules. The “Factory” have in fact stopped producing new firmware. There are many versions and flavours out there. There isn’t really a “Standard” Factory version of firmware.
Your code is the firmware! So you don't need to worry about this. If you intend only uploading your own code to the ESP8266 then you don’t need to restore the factory firmware to the ESP8266. It’s a continuation of the other instructable: Quick Tip: Using Lodash per method packages with Angular (2 and above)Ĭomments are removed for now.This instructable is about updating or reverting the firmware on your ESP8266 to the Factory version.JSConf Budapest 2017 – A personal recap.Push code to board and save espruino -p /dev/tty.wchusbserial14110 -b 115200 -e 'save()' filename.js Push code to board espruino -p /dev/ -b 115200 filename.js Reset the code on your board espruino -p /dev/ -b 115200 -e 'reset() digitalWrite(2, 1) save() Note: Replace /dev/ with your port and the baud rate from 115200 to 921600 when using an ESP32.

Espruino CLI as alternative to using Espruino IDE Tip: See Espruinos Quick Start for writing code Espruino IDE to learn more.
Serial port /dev/cu.wchusbserial1440 tells us which port to use for flashing the ESP and transfering code to it later.
If the driver is correctly installed and activated your Terminal should respond with something like: esptool.py v2.6

You need a command line tool called »esptool« to be able to flash your ESP based development board. Loading the ESP32 driver in the Terminal: sudo kextload /Library/Extensions/SiLabsUSBDriver.kextĪfter loading the driver you have to approve the usage by clicking the ✺llow« button in the »Security & Privacy« system preferences panel. Loading the ESP8266 driver in the Terminal: sudo kextload /Library/Extensions/usbserial.kext
Since macOS High Sierra you have to load and enable the drivers after the installation. Install macOS driversĭownload and install one of the following drivers to be able to successfully connect your development board via USB to your Mac: The main difference (beside the size and the price) is that the ESP32 comes with Bluetooth 4.2 and Bluetooth low energy in addition to the WI-FI capabilities of the ESP32. I recommend using a development board (D1 Mini or NodeMCU) based on the ESP8266 or ESP32 depending on your needs. Fortunately, Espruino can also be used with other, much cheaper boards. Espruino compatible microcontrollersĮspruino sells different own development boards with various hardware features that are specifically designed to work with this firmware.

About Espruinos JavaScript abilitiesĮspruino sports a subset of ES6 features as shown in the language feature list.
This Guide helps you to set things up to explore the possibilities of the Internet of Things using the language of the web.
So it’s possible to run JavaScript natively on the most affordable microcontrollers like the ESP8266. Espruino is a firmware with an integrated JavaScript interpreter for microcontrollers coming with it’s own IDE.
