    Ok... i just realized that i can't require on the left side of the espruino IDE... that was the problem...
    but i still get an error sometimes and sometimes not on trying to make this rfid work:

    ERROR: jshI2CRead:, slave doesn't ACK the transfer.
    NFC error undefined

    So now i'm using 1mb and formatted it... but what i get now is that doesn't find any library from modules folder in project directory and even other libraries that should be present already in the firmware... the error i get is:

    var nfc = require("PN532").connect(I2C1);
    WARNING: Module "PN532" not found
    Uncaught Error: Unable to mount media : NO_FILESYSTEM
     at line 1 col 26
    var nfc = require("PN532").connect(I2C1);
    

    then i format with:

    E.flashFatFS({format:true});
    

    and what i get is:

    WARNING: Module "PN532" not found
    Uncaught Error: Could not open file : NO_PATH
     at line 1 col 30
    var mqtt = require("PN532").create(server, {
    

    what is it happening??

    Hi,
    i got this problem with microsd card reader ... when putting this simple code:

    SPI1.setup({mosi:D23, miso:D19, sck:D18});  
    E.connectSDCard(SPI1, D5); 
    console.log(require("fs").readdirSync())­;
    

    i get:

    Uncaught Error: Unimplemented on Linux
     at line 1 col 25
    E.connectSDCard(SPI1, D5);
                            ^
    Uncaught Error: Unable to mount media : NO_FILESYSTEM
     at line 1 col 39
    console.log(require("fs").readdirSync())­;
                                          
    =undefined
    

    i followed this schema:
    https://farm4.staticflickr.com/3954/3367­5026246_a5bb2ce4c6_o.jpg

    then i followed this schema:
    http://www.espruino.com/File+IO

    i tried with fat32 filesystem, i tried with ext3

    Has anyone implemented a library for A6 chip?

    Can someone help me understand how to implement SIM800L on NodeMCU 1.0?!
    I connected:

    • pin rx from sim800 to tx of NodeMCU,
    • pin tx from sim800 to rx of NodeMCU,
    • vcc from sim800 to 3.3v of NodeMCU,
    • gnd from sim800 to gnd of NodeMCU,
    • rst from sim800 to D5 of NodeMCU

    Then i got this code:

    var wifi = require('Wifi');
    var esp = require('ESP8266');
    var sim = require('SIM900');
    
    wifi.connect("...........", {password:'...............'}, function(err) {
          if (err) throw err;
          console.log("Connected to wifi");
          console.log(wifi.getIP().ip);
    });
    
    var gprs = sim.connect(Serial1, D5, function(err) {
      if (err) throw err;
      gprs.connect('mobile.vodafone.it', '', '', function(err) {
        if (err) throw err;
        gprs.getIP(function(err, ip) {
          if (err) throw err;
          console.log('IP:' + ip);
          require("http").get("http://www.pur3.co.­uk/hello.txt", function(res) {
            console.log("Response: ",res);
            res.on('data', function(d) {
              console.log("--->"+d);
            });
          });
        });
      });
    });
    

    I got console stopping to work.
    I even thought that as NodeMCU is connected to usb and maybe tx and rx of NodeMCU somehow conflict with usb then i changed on code "serial1" to serial2 or serial3 but nothing.
    Then as i thought about the conflict i connected and saved wifi so that i can connect to NodeMCU through wifi for IDE and then send serial connect on next reboot but nothing.
    Well ... can someone tell me how it works please?
    Thanks
