Scene Controller

[Rek]

my w5100 shield was giving me trouble when trying to use it with the rf24. check wires error. Will try soft spi today and see if I can get it working.

@Rek

Yep, check out the github issue above. TMRh20 has already created a branch for us to test.

@korttoma , what's yours like??

The picture is a little dark but you get the idea. White box with blue buttons.

nice job thomas!

@korttoma Hey, that looks good! Where did you get the enclosure?

[korttoma]

@Nuubi from a local electronics shop

the producer of the box seems to be Hammond Manufacturing maybe your local supplier have the same box ;)

Thanks Jim, btw I figured out a neet way to dim the backlight using just a resistor and a transistor. On the I2C LCD driver board there is a jumper for the backlight and I just connected the transistor to these 2 pins and the gate via a 10kR to a PWM pin. Works great.

Also I want to thank you Jim again cause I started from your weather station scene controller and ended up with this:

Finally got around wrapping this up. Hope to provide a youtube demo clip in the coming days. But everything is checked in on github.

Used the following touch screen when creating the example.

Hi Hek - Can you advise what the physical size of the LCD pcb is?

I have a really nice bamboo box that my wifes sunglasses came in ( image here) and this might be an ideal case for it!

( imho...the box is nicer than her sunglasses ( which are now broken anyway )

10x6.5 (cm)
Stacked height about 3.2 cm (2650+shield+display)

First post updated with youtube clip and a link to the build page.

@hek thanks Hek

Man you are costing me a fortune... Now there's another project I will need to try.. :-)

Seriously though, very cool!

[lunarok]

Will it be possible to use with 3.5 LCD instead of 3.2 ? Many differences for the code to make ?
Because now we can find 3.5LCD directly connectable on 2560 and total is cheaper too.

@lunarok

It depends on if the display is supported by the UTFT library I used in the example.

Very cool display, well done!

Hi,

Can't use the sketch.
From codebender include on mysensors it just say there was an error compiling it.
When I clone it, directly on codebenders it say there was a communication error.
When try with local IDE, there is a lot of errors about the time library

This type (for each month and day)
libraries/Time/DateStrings.cpp:18:18: error: variable ‘monthStr1’ must be const in order to be put into read-only section by means of ‘attribute((progmem))’
char monthStr1[] PROGMEM = "January";

[lunarok]

@hek : can you update the mysensors lib in codebenders ? On scene controller page you ask to modify SOFTSPI, it's not on codebenders (unless it makes a copy for me) but it is on git

[hek]

Codebender has a bug when library contains large files (UTFT in this case). This has been reported to them and they will fix it eventually. In the meantime I have just re-uploaded the libraries without these binary (pdf files). But I think they need to clear some caches before it actually compiles.

Enabling SOFTSPI in the MySensors lib-config just for the SceneController is harder because we can only keep one version of the MySensors library at the time in our "repository" on codebender.

Regarding the DateStrings compilation error .. I've just pushed an update which works in IDE 1.5.8 now.

@hek
Can't you define the SoftSPI settings in the sketch, before you load the library header file? (And then make some conditional defines in the library)

(I admit, I don't know the arduino toolchain fully, so I could be mistaken here.. But in "normal" c/c++ compilers you can do it)

Or is the libraries at codebender precompiled?
