Hi vz10, I'm pretty sure that the library can work on 4.1 too. For this, create a new 4.1 project and import the cs files shared by Paolo.

Hope that you will succeed.

Cool.

Did you switch to 4.3.1 ?

I have found that in 4.2.2 when building firmwares with yagarto gcc then the double.ToString function is not working properly due to some missing floating libraries in this compiler. I have planned to switch to 4.3.1 now, which use another gcc that have this support.

I also found that Graphics.featureproj was missing from my TinyCLR.proj file.

I like the video with the neopixels.

Any chance to share your code and hardware design with us ?

Hi All

 

I have  been able to build the Netduino Plus 2 firmware revision 4.2.2 with GCC yagarto tool using the wiki instructions, and I have discovered that the double.ToString API is not behaving as expected with this build. You can use the DFU file called myfirmware-forsanitycheck.dfu contained in the package provided in the wiki page in order to reproduce the issue I'm facing, as both the one provided and the one I have generated, behaves the same.

 

The following code snippet illustrate it :

            double dValue = 10.20;

            Debug.Print("-- value : " + dValue.ToString("F1"));

 

The expected result should be :

-- value : 10.2

but you get :

-- value : -545128520.00000000000000010

 

The strange thing is that the official 4.2.2 firmware (http://forums.netdui...2-firmware-v422) provided for the Netduino Plus 2 is behaving correctly.

 

So is anybody could give me some inputs to track down that issue and work on a fix ?

Is that could be related to : http://netmf.codeple...m/workitem/1385 ?

 

Thanks All

Hi All

I have  been able to build the Netduino Plus 2 firmware revision 4.2.2 with GCC yagarto tool using the wiki instructions (http://wiki.netduino...to-GCC-4-6.ashx), and I have discovered that the double.ToString API is not behaving as expected with this build (see below code snippet).

The DFU firmware file called myfirmware-forsanitycheck.dfu contained in the package provided in the wiki page behave the same and is a god starting point to test the folowing code snippet.

Hi DK

My guess was true, I have built a custom NetduinoPlus2 v4.2.2 firmware with the SPOT_Graphics in it and now I can display them to my panel.

I have enclosed the modified file in order to disable stub libraries and enable the real libs.

Note : it should also work on 4.3.1, but did not test it for now.

Enjoy!

Hi,

I'm on the point to start the build of the 4.3.1 firmware of my N2P, and therefore, would like to know the progress of your work.

Any chance to get an updated tutorial ?

Hi Guys,

I would like to keep tracking of the modifications that I applied on the netduino firmware under source control software like GIT. As the BSP is not clearly split from the Microsoft Porting Kit source code, I would like to know how you are bring in up your repository in order to easily migrate to the comming release of the .Net Micro Framework ?

Any ideas is greatly appreciate.

Regards

Hi DK

I'm trying to achieve that goal too, I need Bitmap class in order to easily draw Text onto my TFT panel. I had a quick look tonight on the content of the Porting Kit in revisoin 4.3.1, and identified the files that list the features to be included. My guess is that you might have to modify the following file :

netduinofirmware_source_4.3.1.0\MicroFrameworkPK_v4_3\Solutions\NetduinoPlus2\TinyCLR\TinyCLR.proj

From Line 114 to 117 it is specified that the Graphics name space is linked to a stub version :

This is a suggestion, I haven't been able to launch the build yet. So if you have time, please try it and let me know.
