Official Thread: Alpha Board Development

Hello Everyone,

Please follow along here to watch the development of the alpha kit for the OSBH project.

Thanks,
Aaron

Is the board operatable by battery only? With the Wifi I don't think so.

One issue with the code was that it was to big for the flash in the spark Core.
We solved that issue for now by switching the firmware to the new feature/hal branch from Spark Core dev team, which is going to be the future code base for the photon as well. Configuring the code for this branch is in that way also future compatible.

To free up more flash space we deactivated the Spark Cloud support.
Steps to do that:

1. build up a local build environment. See https://github.com/spark/firmware/tree/feature/hal22
2. clone the feature/hal branch instead of master: git clone -b feature/hal https://github.com/spark/firmware3
3. compile the OSBH code with make APP=OSBH SPARK_CLOUD=n

I needed to add following lines to the OneWire.cpp file:

#include "OneWire.h"
#include "gpio_hal.h"
#include "pinmap_impl.h"

#ifndef FALSE
#define FALSE (0)
#endif
#ifndef TRUE
#define TRUE (!FALSE)
#endif

Filesize is now about 70kb, which means we have 40kb for more Code!
We still need to do some tests with the new firmware as there seem to be some bugs around, but looks promising.

What is the status of the kit? I noticed the code on github changed.
Is it already possible to build your own sensor? Before there was a wiring scheme and component list on github, but these have been removed.

Hey @mattias--if you go back to the public Repo on GitHub it should all still be in there

Can someone say two, tree words about power consumption / battery operation. There are a hand full commercial products out that run with some batteries a year (load, temperature). Will this be possible with the Particle (former Sparc Core).

Hey-sorry for the delay on answering this.

@AaronM can you fill @Clemens in on the above question? Cheers

Check out the latest prototype of our sensor PCB.

@ron--would you care to post a quick update on this thrread?

Cheers!

Is work still happening on this? I'm considering trying one in a hive next year and figured I'd put it together over the winter. Would love an update. Thank you.
