It's here mentioned a package of Atmel tutorial codes (AT91SAM7X-EK code samples). Will these work for the second generation of Netduino Boards? The reason I have doubt is because the wiki page haven't been updates since 2011 and there is no mention of the second gen. Netduino boards.
Then are there any code snippets I can use as a basis if I want to write native code for a second gen. Netduino board? Is there any place where I can find board.h, pio.h and such that works with the STM32F4? Im kinda new to this.
Something else I noticed when comparing the Netduino schematic and the STM32F4 datasheet (both found here http://netduino.com/...uino2/specs.htm) is that the stated functionality of each pin is expanded when the .NET firmware is removed (?). For example some of the digital pins has ADC functions and more digital pins has PWM functions than stated (see page 39 and onward in the datasheet and compare the pins to the schematic pinout).
Hi knutolai,
Yes, there are some additional features you can use via native code (ADC pins for instance).
The ST micros share a lot of features between different sets of pins...which can be a bit confusing at first, but lets you use the chip in a ton of different configurations.

Are you aware of any major differences between F2 and F4? There seems to be a lot more tutorials and example code covering the F4 then the F2.
Generally speaking, the F2 and F4 are identical. Except that the F4 has a math coprocessor, more speed, more flash, and more RAM. Managed code should work the same on both (and you can usually run F2 native code on an F4 with no changes).

Does these also work as a general purpose C++ firmwares? I would imagine when STDFU erases the .NET netduino firmware I would need a new firmware in order for the MCU to understand my code. Am I correct on this? I'm fairly new to hardware programming and it seems a little overwhelming to write a full firmware for the MCU as well as the actual program I want the chip to run.
knutolai,
If you use the standard templates...you're basically just create your application on top of it.
There's no threading or garbage collection or awesome .NET class libraries. And you may have to deal with pointers. But native code can be fun if you're going that direction.
BTW, the standard templates should in theory set up the microcontroller for you: clocks, power, etc.

That's great to hear Chris!
I'm currently coding my project in Microsoft Visual C++ 2010 Express and the built in compiler seems to have trouble understanding the core_cm3.h system file. Scrolling to line 737 it seems the code wants to be compiled with either a ARM, GNU, IAR or TASKING compiler.
So I'll be searching for a new compiler to run and troubleshoot my program. Is anyone aware of a favorable compiler/toolchain among these? I'm working in a Windows 7 OS.
Edit: I got a MINGW gcc compiler through the Sourcery CodeBench Lite Edition. Editing the code in Visual Studios and running it through the terminal (typ. 'gcc main.c') stuff seem to work though it has trouble finding some of the include files. Seems the 'standard peripherals library'-packages folder architecture is designed for very specific compilers...
