I have a Fez Cobra II card and I wanted to write a simple app that access the SDCard.
My first port of call was to read the boards documentation page here:
It has a piece of code at the bottom which explains how to mount the SDCard drive:
// Determine if an SD card is inserted…
ps = new PersistentStorage(“SD”);
// …and from here use the SD card as normal
I tried typing this into a new gadgeteer application but it did not recognise the PersistentStorage class. Ok, I thought, I need to add a namespace to my app which defines that class.
I searched the web for ‘PersistentStorage GHI Electronics’ and found this documentation page with the class description:
The only problem is that the page only appears for about 1 second before it’s replaced with a white screen showing nothing.
I then managed to grab a screen dump of the page during the 1 second that it was active and it said that the PersistentStorage exists in the GHIElectronics.NetMF.IO namespace which is in a DLL file of the same name.
I searched for this file on my machine but could not find it.
I seem to have hit 3 problems:
The example on the mainboard page does not work when cut and paste into a new project.
The GHI documentation pages do not display correctly.
There are references to namespaces that are not part of the GHI installation package.
I think the idea of the gadgeteer electronics is a great one but if every time you want to do something new with it you have to jump through hoops to find some example code that works, I think people will get put off using it.
Sorry, just venting my frustrations.
