The ESP8266 is so limited that it's definitly not possible. ESP32 can do after deactivate of BLE or if you use a board with PSRAM

Cool - To speed things up you can add "compiled"; to your random value generator function like explained here JavaScript Compilation

There is no module for this ic available.

Check this page for existing modules:

http://www.espruino.com/Modules

There are also some gpio extender available which you could use as a good starting point to build a SX1509 module.

first test with the NRF52LL module

var ll = require("NRF52LL");

var saadc = ll.saadc({
  channels : [ { // channel 0
    pin:D4,
    gain:1/4,
    tacq:40,
    refvdd:true,
  } ]
});

setInterval(()=>{print(saadc.sample());}­,1E3);

Is the result a 16 bit signed integer and presenting a -32767 to +32767 digital value ?

Does switching of NRF improve reads?

Should NRF.sleep() be called if accurate analogRead() are required?

You can also configure the nRF52 hardware to just take readings automatically which is probably the fastest

Ok, have to look into that module

Is analogRead(pin) the quickest way and how accurate is this?

Does switching of NRF improve reads?

There is info in the make file for a 1MB ESP8266 board

https://github.com/espruino/Espruino/blo­b/2e0502cbb721c72fcae6807ac85edd9900b60a­40/make/targets/ESP8266.make#L32

Hmm, my guess it that you overload the ESP8266. The ESP32 has much more memory and should handle it. Well fs is very memory hungry.

nice, can you please upload the openscad file too.

I only use Storage. Can you add a sample to reproduce the crash, or just add infos to https://github.com/espruino/Espruino/iss­ues/1777

👍🏻

make sure to set WebIDE baud rate to 115200

Waveform, just checked the list (https://github.com/espruino/Espruino/iss­ues/1777) of open ESP32 issues. If it's broken please share some info to be added to the list of issues.

Well, tinyMQTT can not handle messages larger than 127 bytes.

In the beginning I tried to bookmark posts that are important to my work, next was to use Search which is ok.

What about extending this forum if possible .....

• switch to https, let's encrypt is free
  
• allow to add flags for conversation and post
  
• extend search for flags
  
  

Anything else?

I guess it can be an empty repository named Forum just for discussion

👍🏻

use scl not SCL

https://www.espruino.com/MicroBit#pinout­

check the pinout and try I2C1

serial attached

http://www.espruino.com/ESP8266

or spi

I use nrf52 and a WIZ850io clone with custom build firmware

Ok, look's like you still think your board is not the issue.

Please try this snippet and if it doesn't work you might be better with a different board.

var Wifi = require('Wifi');
var ssid = '<replace with your ssids name>';
var password = '<replace with your password>';
  
Wifi.stopAP();
Wifi.setConfig({phy : '11n', powersave : 'none'});

 Wifi.connect(ssid, {password:password}, function(err) {
      if (err) {
        console.log('Wifi.connect(err):', err);
      } else {
       console.log('connected');
       Wifi.save();
      }
    });

@stumin Thanks fo sharing, make works. Let's mode this to a new conversation.

@stumin Thanks for sharing your test results. Is it possible to share how you managed to compile with the SDK? Would like to run some device tests and then we could think about switching to this SDK.

Ok, there is maybe a explanation for the different results: Espruino is using SDK ESP8266_NONOS_SDK-2.2.1.tar.gz and arduino using a newer one.
