Is there an update on when we will see OneWire baked into 4.2?

Hi Andy,

I was just chatting with CW2 about this today. He's working on a wrapper for the OneWire class so that you can use the existing CW2-based 1-wire class (much like we've done with AnalogInput and PWM).

He's also working on a few bugfixes to the .NET MF OneWire class. Once those are ready, we should be able to provide a build. It'll match up with 4.2.0.1, where we're making a few other small updates to the firmware.

I'm hoping sometime in the next 2 weeks or so...

Chris



Can't be long now ;)

Just thought I'd give this thread a bump, any exciting news on 4.2 + 1-wire or the 1-wire wrappers? :D

Qucik update: we are now testing the NETMF 4.2 OneWire feature with Netduino Plus. It takes up a bit of flash, and it needs to be deployed as part of the firmware...so we'll create a firmware release for Netduino Plus which shifts the firmware/code-storage boundary a few KB to sneak it in there.

It looks like it has been a long time to add one wire support to the code. Will it be anytime soon?

Thats great news Chris! Will it also be available for standard netduinos? Also are there any plans to implement this on the shield base for the Go! ? Thanks, Andy

I'm anxiously awaiting this update! Let us know when it is available, or if you have a beta version that you'd like some additional testing on.

Yes, we will build a special build of NETMF with OneWire for the classic Netduino as well.

And yes, we will be bringing OneWire support to the Shield Base soon. :)

Hello, is there also a chance for firmware with higher clock resolution? I need it for proper DHT22 sensor handling in my Netduino Plus. Regards

Hi GrZeCh,

Hello,

Regards

What clock resolution do you need?

We're transitioning to the integrated OneWire class from the NETMF 4.2 object model. If it doesn't offer the resolution you need we may be able to patch it to do so...or integrate a new feature into a future version of NETMF.

I think GrZeCh means increased timer resolution mod - he asked me about the 1-Wire implementation in .NET MF 4.2 and possibility to include that timer change some time ago. I did not forget, unfortunately I was busy with other things and now after Netduino firmware 4.2 with the official 1-Wire implementation and 4.3 beta was announced, I am waiting for the source code...

Makes sense. You have mail :)

Hello,

Yes this is exactly what I was requesting. Thank you for remembering :)

Netduino Plus 2 includes support for the native NETMF OneWire classes. If CW2 wants to make a wrapper to provide code compatibility with his excellent OneWire classes, you'd be able to deploy that with your application on the fly.

I would ping CW2 and maybe send him cookies :)

The source code is included in zip archive for "Netduino" (Netduino_v4.1.1_beta1_CW.NETMF.OneWire-1.0.5.0.zip).

Hi, Just wondered if the 4.2 1-wire is available for standard netduino or GO! Shield base now and if so where would I find it? Many thanks, Andy

OneWire is included in the 4.2.1+ firmware for Netduino Plus 2. We'll also be adding support for OneWire to GoBus and Shield Base after the holidays...that's been our #1 request for Shield Base :)

.NET MF 4.2 grew the Netduino Plus firmware quite a bit so there's no room to include CW2's OneWire code without making the deployment sector smaller. We're going to make a single update with OneWire next month...but it may take up a bit of the code deployment sector.

Has OneWire on 4.2 been skiped as a result of the comming of NetduiinoPlus 2???

I still have a bunch of old NetduinoPlus waiting for 4.2 upgrade with OneWire.

What is the status?
