    Hi Gordon

    just tried with putty on Windows 7 with espruino 1.1 v40: this method is certainly more robust than the web app - I can paste multi-line functions without issue. However, if I paste in a full file (into a console that has been first reset() and using code that has been verified to be ok), then something is still amiss as the ">" prompt never turns and stays at ":" as if expecting a closing bracket of some sort, which I don't believe to be the case. This can be verified using the MAX7219 code example I have sent you privately Gordon.

    Thanks

    Neil

    also observed as documented above (just to reinforce that you are not crazy IdeaShaker). I am using Windows 7 with Espruino board v1.1, code v40and the chrome app as posted on the chrome app store

    Also observe that random characters get dropped midline

    eg. SPI2.send (0xf, B6)

    becomes
    SPI2.end(0xf,B6)

    and a subsequent syntax error.
    Line by line copy and paste seems to be the only way in at present

    in 1v41 (october 4th nightbuild), LCD.drawString works fine, but LCD.drawVectorString does not seem to be recognized

    LCD.drawVectorString("hello",50,50,50,0x­8000)
    ERROR: Function not found! Skipping. at line 1 col 5

    The below code (as published on espruino.com) yields:

    ERROR: INTERNAL: Timeout on SPI RX
    

    whenever the touchscreen is drawn upon.
    Have tried different setIntervals ranging from 10 to 100 touchFinc but with no change -any ideas?

    this is observed with Espruino 1v39

    var onInit = function () {
          SPI1.setup({sck:A5,miso:A6,mosi:A7})
          SPI1.send([0x90,0],A4); // just wake the controller up
        };
    
    var touchFunc = function () {
          if (!digitalRead(B6)) { // touch down
            var d = SPI1.send([0x90,0,0xD0,0],A4);   
            var pos = {x:(d[1]*256+d[2])*LCD.WIDTH/0x8000, 
                       y:(d[3]*256+d[4])*LCD.HEIGHT/0x8000};
            touchCallback(pos.x, pos.y);
            lastPos = pos;
          } else lastPos = null;
        };
    
    var touchCallback = function (x,y) {
          if (lastPos!=null) { 
            LCD.drawLine(x,y,lastPos.x,lastPos.y,0xF­FFF);
          }
        };
    
    onInit();setInterval(touchFunc, 50);
