Hi Gordon,

It's interessting to me too. Last time i used assembler is also a long time ago, 68000. Maybe we can use it to write modules? Not to speed up things but for saving memory.

I wonder how we have to access PIN's or UARTs/SPI in assembler.
Or even in C/C++ ?

Sacha

Hi Gordon,

Maybe on the referencepage where you documented "reset()".

I do also have the problem with the IDE Upload. Even with the old IDE. It has something todo with the Chrom/Serial/USB connection. My workaround is the connect and reconnect until i see the ESPRUINO Version information:

Connected
=undefined

=undefined
Connected
=undefined

=undefined
Connected
=undefined

=undefined
Connected
=undefined
echo(0);
<<<<<{"VERSION":"1v59","BUILD_DATE":"Mar 25 2014","BUILD_TIME":"17:17:20","BOARD":"ESPRUINOBOARD","CHIP":"STM32F103RCT6","CHIP_FAMILY":"STM32F1","FLASH":262144,"RAM":49152,"SERIAL":"33FFD705-41573033-27620843","CONSOLE":"USB"}>>>>>

After that procedure uploading works as expected but much slower.

Sacha

Thank you Gordon,

Is VBAT directly routed to USB or Batterie ?

Sacha

Hello There,

What is the max. current i can use on the v3.3 pins ?

Thanks
Sacha

Perfect. Thanks

Sacha

Ok. Thanks.

Workaround with inline function:

setWatch(function(e) { myfunction(B12,e); },B12,{repeat: true, debounce: 20});

Sacha

Hi Gordon,

When the callback function of setWatch is called, an object is passed with the following variables:

"time", "lastTime", "state"

Please include "pin". I would like to use the same callback function multiple times for several pins. So we need to know the pin as well.

Many thanks

Sacha

Hallo Espruinos,

I do not understand how the minify option in the WebIDE works. I enabled it in the options. After codeupload, when i use dump(); i see my code and not a minified version.

Thanks

Sacha

Thanks Gordon for the workaround.

Could it be that when i implement it right know with eval, that this won't work anymore after you fixed it on the "stringify" side ?

Sacha

Hi Alex,

Yes you can connect a espruino to the coordinator or a router/enddevice und communicate using the module without a difference.

Sacha

It should work like this:

http://jsconsole.com/?var%20A15%3D%22ok%22%3B%0A%0Atest%3D%7B%7D%3B%0Atest%5B%27myname%27%5D%3D%27ESP%3A33FFD705-41573033-27620843%27%3B%0Atest%5B%27first%27%5D%3D%7B%22pin%22%3AA15%7D%3B%0A%0Aconsole.log(%27Orig%3A%27)%3B%0Aconsole.log(test)%3B%0A%0Ajson%3DJSON.stringify(test)%3B%0A%0Aconsole.log(%27JSON%3A%27)%3B%0Aconsole.log(json)%3B%0A%0Aconsole.log(%27Back%3A%27)%3B%0Aconsole.log(JSON.parse(json))%3B

Sacha

Hi,

Have some problem with JSON.parse.

test={};
test['myname']='ESP:33FFD705-41573033-27620843';
test['first']={"pin":A15};

console.log('Orig:');
console.log(test);

json=JSON.stringify(test);

console.log('JSON:');
console.log(json);

console.log('Back:');
console.log(JSON.parse(json));

Here is the output:

Orig:
{
  "myname":"ESP:33FFD705-41573033-27620843",
  "first":{"pin":A15}
}
JSON:
{"myname":"ESP:33FFD705-41573033-27620843","first":{"pin":A15}}
Back:
undefined
=undefined

Back is undefined. I expected the same as 'test'.

Thanks
Sacha

Hi Alex,

You need some basic understanding about xBee. The following book may help:
http://shop.oreilly.com/product/9780596807740.do

I try to answer your questions.

You need ONE coordinator, but only ONE!
The rest can be routers or enddevices. Routers as the name says can route to others.
The special of enddevices is, that they can't route but they are able to sleep.

With my module you will be able to communicate with all types (Coordinator/Router/Enddevices)

I think RSSI values or link signal quality can be read out by AT commands. Should be possible with all types of devices.

You need a PC to flash the right firmeware to the xbee's first.
Use the latest xBee firmeware in the API variant.
All the other settings can be done on the PC too or by AT commands from the espruino.

Sacha

Hi Gordon,

Very stable WIFI and/or Ethernet connection with a robust IP stack should be a goal.
Tessel uses the CC3000 too. I'm wonder if they have issues too.

It has also a good part. When there was no problem with WIFI/Ethernet at all, i've never implemented a xBee module ;-).

Sacha

Thank you dirk.

Module is committed.

Oh, did'nt know that. Thanks. Will try it.

Sacha

I left the Espruino over night connected. Just waiting that something happens on the Serial connection (Serial1.onData callback registered). No data received but the timing is way off.

The following statement took 3-4 Seconds only:

console.log("Start-Time: "+getTime()); setTimeout(function() { console.log("After a very long wait.: "+getTime()); }, 10000000);

Start-Time: 49936143.57320594787597
=1
After a very long wait.: 49946147.45812225341796

Hmm. Have some formatting problems.

Gordon:
My second answer (Readme) should be formated as text only.
The modulecode should be completly fromated as code.

Is there another way to submit a module ? EMail ?
Sacha

The module code: Comitted on git-hub

Module for communicate with xBee radios

• KEYWORDS: Module,xBee,API Firmeware, API Mode 1
  
  

Summary

Serial1.setup(38400,{rx:B7,tx:B6,bytesize:8,parity:none,stopbits:1});

functions:

  XBee-API1.AT(command,value,function(re,data) {} )
  XBee-API1.strtobytes(String)
  XBee-API1.TX(addr64,addr16,options,data,function(re,data) {} )
  XBee-API1.RX(function(data) {} )

xBee Frame Types implemented

• 08 => AT Command
  
• 88 => AT Command respond
  
• 10 => Transmit request
  
• 8B => Transmit Status
  
• 90 => RX Packet
  

Hi All,

I just finished my first Espruino module. With this module, you are able to communicate with xBee radios. Use xBee AT firmeware. Connect V3.3, GND and Serial RX/TX to the xBee board.

Sacha

Hi Alex,

Maybe xBee would be an alternative solution for you ? I will contribute a module for it shortly.
