Espruino 2v05

This is a truly massive one - it has been a while coming! Some massive additions though...

It's worth noting that Bangle.js KickStarter units (and Puck.js v2 when released) shipped with a 2v05 release, which is kindof a pre-release. I couldn't release all other boards at the same
time because of issues with increased firmwware size on some boards.

• Storage.list() can now take a RegEx/string to filter returned results
  
• Storage.readJSON now has optional 2nd arg that stops it from creating exceptions on bad JSON
  
• Add euro symbol to 6x8 and 4x6 fonts as char code 128 (ISO10646-1)
  
• ESP32: add environment variable COMPORT to be used with make flash

Hi Gordon,

I have a question:

With the previous version the following code ran correctly, but now I get an error:

Uncaught InternalError: Timeout on SPI RX

                             ^

my code:

A2.write(0); // GND
A3.write(0); // light off
A4.write(1); // VCC
SPI1.setup({ baud: 1000000, sck:A5, mosi:A7 });

var g;

var MONTHS = [
  "Jan","Feb","Mar","Apr","May","Jun",
  "Jul","Aug","Sep","Oct","Nov","Dec"
  ];

function draw() {
  g.clear();
  var t = new Date();
  var date = t.getDate()+" "+MONTHS[t.getMonth()]+" "+t.getFullYear();
  var time = t.getHours()+":" +
       ("0"+t.getMinutes()).substr(-2);
  var secs = ("0"+t.getSeconds()).substr(-2);
  // top left date
  g.setFontBitmap();
  g.drawString(date,0,0);
  // middle time
  g.setFontVector(20);
  var timeWidth = g.stringWidth(time);
  g.drawString(time,(g.getWidth()-timeWidt­h-12)/2,10);
  // seconds over to the right
  g.setFontBitmap();
  g.drawString(secs,(g.getWidth()+timeWidt­h-8)/2,26);
  // send to LCD
  g.flip();
}

function onInit() {
  clearInterval();
  // Setup SPI
  var spi = new SPI();
  // Initialise the LCD
  g = require("PCD8544").connect(SPI1,A6,B0,B1­, function() {
    // When it's initialised, set up an animation at 20fps (50ms per frame)
    setInterval(draw, 1000);
  });
}

var next_state = 1;
function swap() {
  A3.write(next_state);
  next_state = !next_state;
}

function swap_on_down() {
  if (digitalRead(BTN1) == 1) swap();
}

setWatch(swap_on_down, BTN1, true);

onInit();

Do I need to adjust the code for this?

rgds,

Reinoud

That's a very odd one. Please could you post this in a new thread and let me know which board you're using?

If you delete SPI1.setup({ baud: 1000000, sck:A5, mosi:A7 }); and then use this code:

 // Setup SPI
  var spi = new SPI();
  spi.setup({ baud: 1000000, sck:A5, mosi:A7 });
  // Initialise the LCD
  g = require("PCD8544").connect(spi,A6,B0,B1,­ function() {

In your onInit function I imagine it'll fix it though.

maybe stupid question, but how do I start a new thread? :-)

I get another error now:

The board I'm using is an Espruino Rev. 1.3b

@Reinoud Have a look at post #2, section "Removal". Probably the vector fonts had to be removed due to space restrictions for your board.

Good point, I didn't notice that...

I tried to flash with all features (I selected the second option here):

But I still get the same error...

Ok, I tried the following:

1. Downloaded espruino_2v04_espruino_1r3.bin and flashed, everything is ok!
   
2. Downloaded espruino_2v05_espruino_1r3.bin and flashed, same error is back...
   
   

I Guess none of the 2v05 versions have the vector font...

I'l stick to 2v04 for a while then! :-)

thanks and kind regards,

Reinoud

Hi - yes, sorry, that was a mistake in the docs by the look of it - the vector font had to be taken out of those builds.

I guess I could do a third build option with no networking, but the other features?

That would be nice! Another question; the clock seems to go a bit quicker than it should. I read somewhere that I can add a crystal which would fix that. I have a crystal lying around, is it possible to test if the crystal works correctly?

I've just started a new forum post at http://forum.espruino.com/conversations/­347042/ with links to info on adding crystals.

If you've got other questions, please can you start a new post? Just go to the forum for your type of board (http://forum.espruino.com/microcosms/108­3/ for the original Espruino) then click "Post a Conversation" in the top right.

That way other people who are searching for similar problems can find it.

Got it! Thanks! :-)

Do you want me to start a new thread for this too or are you already working on it?

No, that's already done - so the next release will have a separate build in it. In fact the 'cutting edge' builds from http://www.espruino.com/binaries/travis/­master/ now no longer have networking but do have vector fonts, so they'd work for you.

Just a note that hardware SPI write is now fixed on the cutting edge builds too. The fix will be in the 2v06 release

very good! thanks!

Is that this one: espruino_2v05.47_espruino_1r3.bin

Seems to work:
