CW2's ContentThere have been 148 items by CW2 (Search limited from 29-April 23) #56736 Netduino Plus 2 Firmware v4.3.1
I guess you have not set the proper cpu architecture - I think without it the compiler generates some ARM code, which is not supported on Cortex-M cores and TinyCLR is stuck in an fault handler. You'd need to add <DEVICE_TYPE>cortex-m3</DEVICE_TYPE> to Netduino2.settings; and also Microsoft.Spot.system.MDK.Targets might need some additional changes. #59249 Beta: Visual Studio 2013 support
I think the most recent is comment by Sal Ramirez on the official .NET Micro Framework blog (posted on 7/11/2014):
#58907 Windows on Devices? When?

#59997 Windows on Devices? When?
Not from my own experience, as I don't use RTOS on any Arduino, but quick check reveals that ChibiOS, BeRTOS, FreeRTOS support AVR (and there is about 40 more in the Wikipedia list that mentions AVR). #59469 Windows on Devices? When?
#58446 Netduino Fritzing part
#56883 I2C Bus Problem - Debugging
For Netduino 2 you need to modify only files in Targets\Native\Netduino_STM32. The STM32 folder contains the original Oberon's implementation, which is not used - Netduino_STM32 is basically STM32 + Secret Labs' modifications.
In fact, you could delete all subdirectories in Targets\Native and Solutions that do not have Netduino,Template or Windows in their name - I usually do that to reduce code search result noise... #56879 Netduino 2 Firmware v4.3.1 with GCC support
Those are libraries and stubs for tools and Windows2 solution, which do not need to be rebuilt when you make changes to a particular solution (your firmware).
There are a few 'clean' targets, you can display them for example by launching msbuild Solutions\Netduino2\dotnetmf.proj /t:Help For a 'complete clean' build, delete the build output directory rmdir /s /q BuildOutput #56874 Netduino 2 Firmware v4.3.1 with GCC support
According to .NET Micro Framework Porting Kit 4.3 ReleaseNotes.txt "Either Visual Studio 2012 (Express edition or greater) or both .NET Framework 3.5 and Windows SDK for Windows" is required. #56866 Netduino 2 Firmware v4.3.1 with GCC support

Edit 2014-03-18 19:30 UTC: Added Visual Studio to prerequisite list #56884 Netduino 2 Firmware v4.3.1 with GCC support
Well, assuming that you don't have JTAG/SWD in-circuit debugger, the options are... ...challenging
#56876 Netduino 2 Firmware v4.3.1 with GCC support
No, you can safely ignore this warning. IIRC it is caused by incorrect ToolsVersion attribute value in a few project files, which causes MSBuild 3.5 to be run, instead of 4.0. I have already fixed such issues, but in separate 'cleanup' branch, which will be integrated into a future release... #57323 Netduino 2 Firmware v4.3.1 with GCC support
Well, you don't have to use that (if you mean the firmware source). Adding GCC support allows you to use free GCC-based toolchains to compile the firmware - otherwise, you have to pay several thousand dollars for commercial ARM toolchains (such as Keil MDK). #57195 Netduino 2 Firmware v4.3.1 with GCC support
Yes, the GCC-related modifications have been made for Netduino 2 firmware only. But the most-important ones were made in the core .NET Micro Framework source code and are shared by Netduino Plus 2 firmware too - basically, adding a proper scatterfile and fixing possible GCC compiler errors in the additional libraries the Plus 2 firmware uses (network etc.) should be all that is needed to make GCC built firmware for the Plus 2.
Well, the modifications are available under Apache 2.0 license, so both Microsoft .NET Framework and Secret Labs teams can easily integrate them into their respective code #59621 High Resolution Quad Encoder Problem
If you are referring to quadrature encoder inputs then no, it is not a secret. It is described in the STM32 datasheet, in fact many [modern] microcontrollers have such interface. For STM32F4 there is firmware with QuadratureEncoder class by NicolasG (for FEZ Cerberus, but it should not require too much work to port it over to Netduino gen 2). #59616 High Resolution Quad Encoder Problem
They cant, but some of them (gen 2) have [hardware] timers with quadrature encoder inputs #57050 Adafruit Ultimate GPS with N+2. Any experiences?
#57039 Adafruit Ultimate GPS with N+2. Any experiences?
Was Netduino running during that time?
How far is Netduino from the GPS module? Have you tried adding some shielding to Netduino? If not, try placing a grounded metal sheet between Netduino and the GPS module, or carefully wrap Netduino in aluminium foil and connect it to ground - but make sure it does not short out the pins on the bottom, better to place some paper or tape there. #58049 how to set external REF voltage for ADC & REF voltage min and max values
The LQFP64 package does not have VREF pins exposed, you'd need a bigger package (e.g. LQFP100). #59916 Convert Arduino Library To Netduino
Unfortunately, I don't have any MAX7219, but it seems to be fairly easy to operate the cascade:
[Netduino] MOSI -> DIN [ Max#1(16 bits)] DOUT -> DIN [Max#2(16 bits)] DOUT -> ...
CS ------------- LOAD/!CS ------------------- LOAD/!CS
Note: The clock (SPI CLK) signal is omitted for sake of brevity, it must be connected together. var maxChain = new SPI(new SPI.Configuration(...)); var numberOfDevices = 2; var data = new byte[numberOfDevices*2]; // Important note: The following order is most likely wrong, // too lazy to think about it... data[0] = 0x01; // Max#2 Data data[1] = 0x0F; // Max#2 Address data[2] = 0x00; // Max#1 Data data[3] = 0x00; // Max#1 Address maxChain.Write(data); #59914 Convert Arduino Library To Netduino
Well, how should I put this... the whole LedControl code is basically one SPI.Write() method call to transfer 16 bit data (spiTransfer() function) to the MAX and a few methods that set the data to perform the desired command.
...
public static void Main()
{
var max = new SPI(new SPI.Configuration(...));
var data = new byte[2]; // 16 bits (address + 8 bit data)
// Display test mode
data[0] = 0x0F; // Address
data[1] = 0x01; // Test mode on
max.Write(data);
Thread.Sleep(Timeout.Infinite);
}
Once you get the code working (written from head, so probably does not even compile, data buffer can be ordered the other way round etc.), you can add command constants and wrapper methods, then you will be able to use the Arduino code because you'll see what it does and where it fits. #59870 Convert Arduino Library To Netduino
You have left empty function declarations in your C# class - this is valid in C/C++, where you can have empty function declaration (in .h) and then implement in at different place (.cpp), but not allowed in C#. Delete all empty functions at the beginning of the C# file, where you have the class declaration from C++ header. #59902 Convert Arduino Library To Netduino
C# does not support binary literals - you'd have to either define those Bxxx constants like
const byte B01111110 = 0x7E; const byte B00110000 = 0x30; ...
or use the hex literals directly, i.e. instead of B01111110 write 0x7E. #59907 Convert Arduino Library To Netduino
Well, those are Arduino library function calls and some constants - the good news is you don't need to convert that, just implement spiTransfer() function to call .NET Micro Framework SPI.Write() method and delete all pinMode(), digitalWrite() etc. calls, which are not needed (because SPI class does that internally; including the ChipSelect pin if you set it in the configuration). | ||||||||||||||
