Tried to reduce JSVARs by changing the 40,000 value in ...../targets/esp32/main.c (Did not find any other place to do it)

static void espruinoTask(void *data) {
  int heapVars;
  PWMInit();
  RMTInit();
  SPIChannelsInit();
  initADC(1);
  jshInit();     // Initialize the hardware
  heapVars = (esp_get_free_heap_size() - 40000) / 16;  //calculate space for jsVars **** modified 40,000 to 60,000
  heapVars = heapVars - heapVars % 100; //round to 100
  if(heapVars > 20000) heapVars = 20000;  //WROVER boards have much more RAM, so we set a limit
  jsvInit(heapVars);     // Initialize the variables
  // not sure why this delay is needed?
  vTaskDelay(200 / portTICK_PERIOD_MS);
  jsiInit(true); // Initialize the interactive subsystem
  if(ESP32_Get_NVS_Status(ESP_NETWORK_WIFI)) jswrap_wifi_restore();  
[#ifdef](https://forum.espruino.com/search/?q=%23ifdef) BLUETOOTH
  bluetooth_initDeviceName();
[#endif](https://forum.espruino.com/search/?q=%23endif)
  while(1) {
    jsiLoop();   // Perform the primary loop processing
  }
}

With little or not success, JSVARS reduced, but still not working.

My be this is exceeding my knowledge, will wait for @maze1980 version.

Thanks to all, for your efforts.

Thanks for the answers, will try to compile with less jsvars.

Thanks....

Hello everybody,
I tried with different versions of firmware (2.04) and have every time the same issue:

Regards, pinnchus

I will try to clean the code, and trace the call´s order, and come back again tomorrow. But basically the call to start is in the require(ssd1306) callback.

Thanks for your help.

OK, i found it. This SSD1306 module, apparently, need at least 1.5 seconds to stabilize.

if I plug the USB, connect the IDE and execute "g = require("SSD1306").connect(i2c, start, { height : 32 });" from the console the display update all the information. Looking further to understand why...

Looking further, The problem apparently lies in the initialization of SSD1306.

This is the full code

After upload, did you a) run it and then save it? - or b) save it right away?
I have tried both options.

Save will after completion call onInit, can you verify that?
Yes it does, in fact while connected it works very well. The problem happens when I connect it without a console, but in the code I do not have any call to write to the console.

Compacting Flash...
Calculating Size...
Writing..
Compressed 81600 bytes to 19967
Running onInit()...

if force the running mode with load(), works ok...

>load()
=undefined
Loading 20034 bytes from flash...
Running onInit()...

I 'm sure you already worked through the Troubleshooting section...
Yes I did but without success.

Thanks for your help.

I think a my be doing something wrong, when run the code from the IDE, everything runs fine. But, when i try to save the code, wrapping the initialization code in a function and calling it from the onInit function does not run unless I call it manually with load(). When I run manually load() everything runs fine too.

The code is uggly, but it's working when i run it manually.

//All VAR are declared globally
function initializeall() {
  require("Font6x8").add(Graphics);
  require("Font8x16").add(Graphics);
  i2c = new I2C();
  i2c.setup({ scl : B6, sda: B7, bitrate: 1000000  });
  g = require("SSD1306").connect(i2c, start, { height : 32 });
  dht = require("DHT22").connect(B5);
  Start_read();
  pinMode(B15,'input_pullup');
  pinMode(B14,'input_pullup');
  pinMode(B13,'input_pullup');
  setWatch(selection, B15, { repeat: true, edge:'falling', debounce:20});
  setWatch(BtnUP, B14, { repeat: true, edge:'falling', debounce:20});
  setWatch(BtnDown, B13, { repeat: true, edge:'falling', debounce:20});

}

function onInit() {
  USB.setConsole(true);
  setTimeout(function () {
                initializeall();
                }, 
      1000);
}

Does anyone has a hint?

Thanks

Hi, there is any simple way to scroll text in a 32x8 Led Matrix with MAX7219 controller? Any help will be appreciated.

Thanks and regards

@allObjects Thanks!!!!

Have you posted the module somewhere accessible?

Thanks,

I2C or SPI and an expander ? Endless pins... with i2c even read.

I would like to port it to STM32F405, should be an easy task but there is too many place with #define ... will try compiling as a PICO and change only linker file and mem.

Thanks!!!

@Stevie, Would you mind to share your C library?

Thanks,

Sure blowfish is one of the strongest algorithms but it is a heavy resource consuming too and don't know if it is really useful for this kind of use.

May be..., As I see both implementations are very easy to try, I suppose we can do both as a module.

If you like it, you could take a look to this js implementation http://www.movable-type.co.uk/scripts/tea.html

A simple but effective message encryption could be http://en.wikipedia.org/wiki/XTEA it is lightweight and should be fast enough.

Try with this examples http://forum.arduino.cc/index.php?topic=159851.0

Absolutely right, i'm feeling like an idiot.

Thanks
