How to install (or upgrade to) .NET Micro Framework v4.2 SDK
To upgrade a project (for Netduinos flashed with .NET MF 4.2)
Click on the Project menu, then click on "<ProjectName> Properties" in the menu.
Select the "Application" tab
Select the desired "Target Framework" in the pull-down (either v4.1 or v4.2)
If you try to deploy a .NET MF 4.1 project to a .NET MF 4.2 board (or vice-versa), Visual Studio will tell you that the assembly libraries' versions do not match.
Compatibility with .NET MF 4.1 projects and boards
The new SDKs will work with Netduinos flashed with .NET MF v4.1.
New AnalogInput and PWM classes -- backwards-compatibility notes
.NET MF 4.2 adds new AnalogInput and PWM classes. To use the earlier SecretLabs' AnalogInput and PWM classes, add the respective assembly as a reference in your project and use the full "namespace + class name" of the classes.
For instance, to use SecretLabs.NETMF.Hardware.PWM (instead of the new Microsoft.SPOT.Hardware.PWM class):
// add SecretLabs.NETMF.Hardware.PWM.dll as a reference to your project.
// PWM pwm = new PWM(Pins.GPIO_PIN_D5);
// becomes...
SecretLabs.NETMF.Hardware.PWM pwm = new SecretLabs.NETMF.Hardware.PWM(Pins.GPIO_PIN_D5);
Odd question about the .NET Micro Framework 4.2.. You say to uninstall v4.1 (QFE1) framework.. but I have them both installed. Why is uninstallation necessary? (It's been working fine like this since I tried out 4.2RC5..) Just wondering if anything would break.

The .NET MF 4.2 SDK includes the files for the 4.1 SDK as well. You may be able to install both, but it could mess with the installer's reference counting.
We make the recommendation in part to help you avoid potential installer glitches in the future.
The Netduino SDK will auto-upgrade the older version, so technically if you try to install both the older and newer Netduino SDK...the newer one will uninstall the old one automatically.

Got it, good to hear. Haven't had any trouble yet - if I do, uninstalling v4.1 will be the first thing to go. (I use it for another development platform, so the longer I can keep it around, the better!)

Hi,
Can use
using SLPWM = SecretLabs.NETMF.Hardware.PWM;
...
SLPWM pwm = new SLPWM(Pins.GPIO_PIN_D5);
Chris,
I get an error when trying to install the 64-bit Netduino SDK v4.2: "Error reading setup initialization file."
I'm running Windows 8 (64-bit); I did not have this problem with the v4.1 SDK.
I first tried uninstalling v4.1 and installing v4.2, then installing v4.1 and installing v4.2 (to "upgrade"), but got the above error both times once I got to the v4.2 install.
Regards,
RWL (Jerry)
I just tried this on my Windows 8 "Release Preview" laptop and it installed. Hmm...
Can you try saving the SDK installer on your desktop and then running it?
Also...are you running Windows 8 beta or the brand new RTM release?
Chris
I did try installing from the desktop. It might be the Win8 version - I'm still running the consumer preview. I'll upgrade to the RTM and try again, thanks!

No problem. If that still doesn't work for you, then we can get you an MSI version of the installer and run it in diagnostics mode on your PC. That will generate a log file to help us understand the situation better.
Hi Chris,
I need to buy some minis for my classroom. Where can I get them from with 4.2 already installed? I think I bought some from you guys directly but I can't recall.
Thanks,

Finally got my system upgraded and everything reinstalled. (Well, enough reinstalled that I can program my N+ again.)
Got MF updated to 4.2, and the firmware on the device is now 4.2.0.0. Config change and an additional .dll referenced (I use the SecretLabs' Analog objects), and I'm back up and running!

Can I upgrade/install v4.2 on a Mini?
I am trying to decide between 4.1.1 beta 1 for the StorageDevice support and v4.2. I'm also assuming that v4.2 has the StorageDevice support.

Yes, you can install .NET MF 4.2 on a Netduino Mini. Just FYI...we're working on an update for the RS232 version of the Mini firmware, which should be ready later this week.
v4.2 should have StorageDevice support. If you run into any troubles, just let us know.

Sounds good Chris, thanks for the quick update! I use TTL so this should be okay for me. I think I just screwed things up though. I went ahead and installed 4.1.1 beta 1 and now neither MFDeploy or Visual Studio can talk to the device. Putty is fine though so I know something is working. I might have to erase and reflash.
Sorry to hijack the subject, but can I use a mk II ISP to reprogram these guys? I use AVR Studio, will that work? I'm assuming just hook up MOSI, MISO, SCLK, etc.. from the programmer and I should be good to go.

That programmer is designed to work with AVRs; you'll need to use SAM-BA to flash the bootloader on these Atmel ARM microcontrollers.
Chris,
I'm trying to use the new AnalogInput classes, but how do I define an AnalogChannel that corresponds with Cpu.Pins.GPIO_PIN_A0?
I'm not seeing a link between the two.
Thanks
