PWM and WDT resets

Hi, can anyone give the current state of play with PWM functions with espruin­o_1v84.tve_master_d8dec28_esp826­6?
Intro states it's not yet implemented, but see code in github
https://github.com/espruino/Espruino/blo­b/master/targets/esp8266/jshardware.c
jshPinAnalogOutput

So I've been playing - trying getting it working. Im getting WDT timeouts when ever I call 'analogWrite' in any of its forms

analogWrite(D4, 0.5);
=undefined

Working with Web IDE so the following message gets sent to the UART

 ets Jan  8 2013,rst cause:4, boot mode:(3,3)

wdt reset

load 0x40100000, len 1396, room 16

tail 8

chksum 0xc0

csum 0xc0

2nd boot version : 1.4(b1)

  SPI Speed      : 40MHz

  SPI Mode       : DIO

  SPI Flash Size & Map: 32Mbit(512KB+512KB)

jump to run user1 @ 1000

Tried a number of combinations:
Tried pin D14 too

D4.mode('af_output');

analogWrite(D4, 0.5,{freq:10});

D4.mode('output');

analogWrite(D4, 0.5,{freq:10});

analogWrite(D4, 0.5,{freq:100, soft:true});

analogWrite(D4, 0.5);

PS
Great project and fun to play with..

Hardware PWM doesn't work. The person who added the code didn't get it to work and I haven't looked at it, so I can't really tell you why it's not working. Have you tried the software PWM?

Hi, I can't get the software PWM to work either. I get a WDT reset if any call is made to analogWrite(..)

D4.mode('output');
=undefined
analogWrite(D4, 0.1, {soft:true});
=undefined

Disconnected

Looking at it, there is no software PWM at the moment. It just needs a few lines copying over from the STM32 port - it could probably just do soft PWM for everything (whether requested or not)

@tve check this out - should be pretty easy to apply to ESP8266?
