Update this code for the latest Espruino firmware

Hello,

I'm new in the Espruino universe, but I'm learning very quickly ;) and I would like to update the code of this project so that it can work with the latest Espruino firmware.

Currently, after performing several tests, the code of this project only works with the 1v95 version, which will admit it to you and the oldest firmware and I would like to enjoy all the improvements that have been brought since.

• Project Page and Instructions
• Github Page of the project

Thanks a lot

And this is the code :

The config file :

fs = require("fs");

var config = {
  firmwareVersion: 'PhotoPizza v5',
  wifiSsid: 'PhotoPizza',
  wifiPassword: '9994501234',
  wsPort: 8000,
  state: 'waiting',//started
  framesLeft: 36,
  frame: 36,
  allSteps: 109000,
  pause: 100,
  delay: 300,
  speed: 3000,
  acceleration: 100,
  shootingMode: 'inter',
  direction: 1
};

function saveConfig() {
  fs.writeFileSync('config.txt', JSON.stringify(config));
  console.log('Save config');
}

E.flashFatFS({ format: true });
saveConfig();

var riadTimer = setTimeout(function () {
  var readConfig = JSON.parse(fs.readFileSync("config.txt"));
  console.log(readConfig);
}, 1000);

And the code of project :

var config = {};
var run = function () {

  function saveConfig() {
    if (JSON.stringify(config) != fs.readFileSync("config.txt") && !setupMode) {
      fs.writeFileSync('config.txt', JSON.stringify(config));
      console.log('Save config');
    }
  }

  var photoPizzaIp = 'disconnected';
  var wifi = require('Wifi');
  var wsocket;
  var server;

  function wifiConnect() {

    wifi.connect(config.wifiSsid, {password: config.wifiPassword}, function() {
    
      console.log(`Web server running at http://${wifi.getIP().ip}:${config.wsPort}`);
      photoPizzaIp = wifi.getIP().ip;
      StartDisplay();
    });
    
    server = require('ws').createServer();
    server.listen(config.wsPort);
    server.on("websocket", function(ws) {
      wsocket = ws;
      ws.send(JSON.stringify(config));
      ws.on('message',function(msg) {
        var configIn = JSON.parse(msg);
        config = configIn;
        //console.log(config);
        NumControl();
        if (configIn.state === 'start' && config.state != 'started') {
          BtnStart();
          config.state = 'started';
          ws.send(JSON.stringify(config));
        }

        if (configIn.state === 'infinity' && config.state != 'started') {
          infiniteRotation();
          ws.send(JSON.stringify(config));
        }
  
        if (configIn.state === 'stop') {
          BtnStop();
        }
      });
      ws.on('close', function() {
        wsocket = false;
      });
    });
    wifi.on('disconnected', function() {
      console.log('Lost WIFI! Disconnected.');
      photoPizzaIp = 'disconnected';
      StartDisplay();
    });

  }

What's wrong with the old code? Does it just 'not work', or are there errors?

Hi @gfwilliams,

With the last firmware version, this is the screenshots result for the config file, and for the project code (2nd file).

I don't actually see any real errors there. I wonder whether the warnings come from Bluetooth being enabled? I'm not sure though.

Does it just 'not work' on 2v09 then? Or what isn't working that should be?

@gfwilliams, When I download the configuration file (1st file), "flash mode" without problem but this error is displayed:

• WARNING: scan stop failed
• WARNING: set rssi scan not implemented yet
  ...

Then after the reset, the config is present. But when I try to upload in RAM the second file, the sending stops before the end and impossible to save it!

• Prompt not detected -upload failed - Trying to recover ...

WARNING: scan stop failed
WARNING: set rssi scan not implemented yet

ESP32 firmware still has some debug infos output as warnings which can be ignored

Prompt not detected -upload failed - Trying to recover ...

This can happen when the upload has code that are not in function because they are executed immediately.

I think the issue is that both files should be uploaded to RAM. By uploading the fist to flash you're making it erase the 'FlashFS' literally every time the device boots, which causes the hang.

Manually enter reset(1) on the left-hand side, then upload both files to RAM, and you may well be fine
