• How to flash an ESP32 board (WiPy 2.0)

  in ESP32 • 6 years, 11 months

  

  I put bootloader.bin,partitions_espruino.bin,e­spruino_1v92_esp32.bin in a zip file, you can use these files to flash espruino on your esp32.

  Run fs.readFileSync before fs.statSync will cause ESP32 exception.
  example:
  var fs=require("fs");
  fs.writeFileSync("temp.txt", "hello 123");
  fs.readFileSync("temp.txt");
  fs.statSync("temp.txt");

  espruino version 1v92
  console output:

  fs.statSync("temp.txt")
  Guru Meditation Error of type StoreProhibited occurred on core 0. Exception was unhandled.

  NanoJS is designed by a friend of mine, he is too busy to maintain the board. So we stopped selling the NanoJS. Of course, I want to resell the existing Espruino board. I hope the Chinese community can help you to get more Espruino board users. Maybe we need more connection by skype or QQ.

  Hi Gordon,
  I'm sorry to make you frustrating:(
  I built up the espruino.cn. The original goal of espruino.cn is just a community for Chinese espruino users. I have my own job and I maintain this community in my spare time. By the way I have stopped selling the JS On Board and NanoJS several months ago. So we have no conflict of profit now:)

• program your Espruino from anywhere in the world by web browser

  By the way~
  Zero+ is an IOT controller, behind the HW(SoC for home router), there are customized OpenWRT system, Language Interpreter(customized LISP), Cloud Service and Web IDE. So all of these composite an IOT platform. You can define the execution logic both in Cloud and in HW(Zero+) by writing code in Zero+ Web IDE. By using customized LISP language, you can define your own program syntax.
  It's more convenient to controll your Espruino by using Zero+ from Internet.

  Actually, I refered to the page(http://www.espruino.com/WiFi+Remote+Cons­ole) to create my page(Espruino Web Console via Zero+).
  In my opinion, "WiFi Remote Console" is for LAN(Local Area Network), "Espruino Web Console via Zero+" is for WAN(Wide Area Network).

  Hi there!
  Little interesting~
  I can program my Espruino from anywhere in the world by web browser.
  The key point here is Zero+, it's an IOT controller.
  You can find Zero+ in indiegogo https://www.indiegogo.com/projects/zero-­plus-a-rapid-smart-devices-builder/x/885­7329

  I connect Zero+ and Espruino via UART interface. I will post more detailed information later if you're interested in this topic.
