Espruino on your watch!

Latest firmware, kind of watch-like:

var initCmds = new Uint8Array([ 
0xAe,0xD5, 0x80, 0xA8, 31,0xD3,0x0,
0x40,0x8D,0x14,0x20,0x01, 0xA1,
0xC8,0xDA,0x12,0x81,0xCF,
0xD9,0xF1,0xDb,0x40,0xA4,
0xA6,0xAf ]);

var dc = D0;
var cs = D2;

var g = Graphics.createArrayBuffer(63,15,1,{vert­ical_byte : true});

var spi = new SPI();
spi.setup({mosi: 29 /* D1 */, sck:30 /* D0 */});

digitalPulse(D1,0,10);//rst
cs.reset();dc.reset();spi.write(initCmds­);delete initCmds;cs.set();

g.flip = function() { cs.reset();dc.reset();spi.write([0x21,0,­127,0x22,0,7]);for (var i=0;i<4;i++) {spi.write(0xb0+i,0x00,0x12);dc.set();sp­i.write(Uint8Array(this.buffer,64*i,64))­;dc.reset();}cs.set();};

var n=0;

function onSec() {
var d=new Date();g.clear();g.drawString(d.getHours­()+":"+d.getMinutes()+"."+d.getSeconds()­);g.flip();if (n++>10) {spi.write(0xae,cs);clearInterval();}
}

pinMode(D4,"input_pullup");
setWatch("clearInterval();setInterval(on­Sec,1000);n=0;spi.write(0xaf,cs);",D4,{e­dge:"falling",repeat:true});

Turns out 200 variables really isn't very much!
