  Does Espruino support scheduler or simple task manager?

  What is your display brand/model number? Some of those SSD1306 displays have different connections internally and need different initialisation codes :(

  SSD1306 oled display from china has a number at back side: GM009606A , i used it with my C library in keil. It worked nice. How can i repair it? Where i can find source file to fix it?

  Next time i tried to connect CC3000 wlan module (TI CC3000 booster pack), but compiler says than cc3000 and http modules not found and i have a log :

  ERROR: Timeout in CC3000 driver (16384)

  SPI1.setup({ sck : 27, miso : 26, mosi : 25, baud:1000000, mode:1});
  var wlan = require("CC3000").connect(SPI1, 24 /* CS */, 23 /* EN */, 22 /* IRQ */);
  wlan.connect( "Amigo_WiFI", "*******", function (s) { 
    if (s=="dhcp") {
      require("http").get("http://www.pur3.co.­uk/hello.txt", function(res) {
        res.on('data', function(data) {
          console.log(">" + data);
        });
      });
    }
  });
  

  Is CC3000 supported? I use nrf52DK

  yes. Understood)
  Now i defined ble service:

  //Start BLE service
  NRF.setServices({
    0xABCD : {
      0xDCBA : {
        value    : 0x01,
        //maxLen   : 1,
        writable : true,
        readable : true,
        onWrite  : function(evt) {
          digitalWrite([LED3,LED2,LED1], evt.data[0]);
        }
      }
    }
  });

  I rebuild code with soft i2c, ssd1306 works, but it skips every other line. And symbols seems are broken. What a problem may be?

  And one else question. Are i2c pins already defined by default?
  if yes, what are their pin numbers?
  I try to use SSD1306 but it doesn't works

  Hi everyone! I use nrf52-DK with Espruino ide.
  I want to start soft i2c. I tried to use hardware and software examples as http://www.espruino.com/I2C.
  I wrote a code:

  // set up SPI
  var i2c = new I2C();
  i2c.setup({ scl : 30, sda: 31 });
  // Write a single byte (0) to address 0x52
  i2c.writeTo(0x52, 0);
  
  

  but everytime i have an error message like:

  *

  Uncaught Error: Function "setup" not found!
  at line 1 col 5
  i2c.setup({ scl : 30, sda: 31 });
  Uncaught Error: Function "writeTo" not found!
  at line 1 col 5
  i2c.writeTo(0x52, 0);
  *

  Could anyone help me?
