#52734 Toolbox.NETMF.Hardware.core help?
Posted by philvr on 13 September 2013 - 07:43 AM in Netduino Plus 2 (and Netduino Plus 1)
Please can someone explain the purpose of these interfaces? I don’t quite understand how they are intended to be used as there are no direct assignments to the netduinos i/o ports. Is there a tutorial anywhere that demonstrates usage? As an example IParallelOut.cs is reproduced below. I apologise in advance if there is an obvious answer, it is taking me some time to get to grips with c#, I am not a programmer by nature and my brain is having difficulty adapting The write must take as an argument some port that has been created elsewhere but how is it created? namespace Toolbox.NETMF.Hardware { /// Generic Purpose Output Array interface public interface IParallelOut : IDisposable { /// Amount of bits in the array uint Size { get; } /// Writes a block of data to the array /// The block of data to write void Write(uint Value); /// Returns the last written block of data /// The last written block of data ] uint Read(); } }

Just a follow up to state that now I have no issues when deploying onto the Netduino Plus MK2 (with the latest production firmware). The software builds and deploys almost immediately every time.

#53894 Netduino Plus I2C just stops working ?!

FYI: The i2c issue seems resolved using the latest 4.2 firmware (and I haven't needed to order a Raspberry Pi)
#53895 Toolbox.NETMF.Hardware.core help?
Posted by philvr on 08 November 2013 - 10:30 AM in Netduino Plus 2 (and Netduino Plus 1)
Agreed that reading all the examples, etc in the forums really does help to learn and indeed I have learned a great deal from other peoples work. I offer a BIG THANK YOU! to all that have contributed code to the forums.
But - I never did not find a direct answer to my question...
#53896 Code optimisation? Shift left/right instead of divide by 2?
Posted by philvr on 08 November 2013 - 10:40 AM in General Discussion
Is it worth testing the optimisation abilities of the Microsoft Development Environment (Visual Studio) in greater depth? If the Development Environment was originally designed for producing desktop and server based applications could it be that optimisations produced for embedded system code are not what they could be ? What if the environment had been aimed at producing embedded code right from the beginning? We are not talking about producing optimised machine code (are we?) but an intermediate language understood by the CLI. That also raises the question of how the JIT element fits in.... (please correct me if I am wrong)

Thanks for clarifying - Admittedly I don't fully understand the process involved - I'll do some background reading tonight, promise!

#54150 i2c bus speed? Is there a limit beyond 400kHz?

#54170 i2c bus speed? Is there a limit beyond 400kHz?
Posted by philvr on 19 November 2013 - 11:04 AM in Netduino Plus 2 (and Netduino Plus 1)
Thanks. I should have read the data sheet...
Another question is just how reliable is the netduino I2C firmware? Has anyone stress tested the i2c implementation? As I am moving toward a commercial product it would be interesting to develop an idea of how robust it is.
