  hi @MaBe I use Pico this time

• Any good way for analogRead readings calibration?

  in General • 1 year, 5 months

  

  hi, I want to write code for analogReads sampling, in C i use for loop, I want to make let say 50-100 reads before I print them to console or to display, then can make analogRead a bit more precise as the readings floats a bit when use just simple analogRead function and timer Interval,
  I appreciate some advice in this case

• simple explanation how to save code that espruino run on start?

  I still have same error in console, even after sucessful firmware upgrade by ./wiflash

  Uncaught ReferenceError: "Graphics" is not defined
   at line 1 col 20
  k(c);var g=Graphics.createArrayBuffer(128,f[4]+1,­1,{vertical...
                     ^

  var g = require("SSD1306").connect(I2C1);
                                         ^
  =undefined
  

  I've been trying to upload this code

  pinMode(NodeMCU.D3,'input_pullup');
  pinMode(NodeMCU.D4,'input_pullup');
  
  function draw(){
    g.clear();
    g.drawString("Hello World",0,0);
    g.flip();
  }
  I2C1.setup({scl:NodeMCU.D4,sda:NodeMCU.D­3});
  var g = require("SSD1306").connect(I2C1);
  

  I deal with another NodeMcu, before I tried with Lolin board and now with CP2101 chip, but still can't connect OLED

  hi, had anyone some issue with nodeMcu Lolin with CH340G to make it work generally on mac?
  when I plug it into usb port it will restart my mac,
  however on PC it is working eg. with arduinoIDE,
  in Espruino case, when I use PC it flash code for Espruino firmware for ESP8266 but wifi upload not work, not sure what's wrong because when I connect another no nodeMcu Esp8266-12E board it works fine, I can flash Espruino firmaware by usb and upload code by wifi,
  it could be problem whith this board? (this board works with OTA arduino)
