#62170 C# help

Posted by JBkey on 17 April 2015 - 01:39 PM in Visual Studio

Hi.

I'm stuck with variables format. I know this is a stupid question but I'm on it for 2 hours and I'm losing my mind.

I began in this programing stuff maybe 2 months ago, so I'm really new at it.

The problem is:

I have:

command.Data = new ushort[] { xx, yy, zz };

And I need to do:

ushort zz = System.Math.Tan(c1AngleX);

But the output of System.Math.Tan is "double", so I kinda can't have the "ushort" there.

I tried this

ushort zz = (Convert.ToUInt16 (System.Math.Tan(c1AngleX));

But I can't.

There's any way to convert "double" to "ushort"?

Just a quick question.

I'm having a small construction problem that consists on don't having enough space to have the reset button accessible in where I need Netduino to be.

The question is, how does the "/reset" pin works? that one between "IOREF" and "3V3". Can I reset my Netduino through there like the same way I do in the button? Or I have to unsold the button and resold another?

(sorry for the english, for me it makes sense, but I don't know if it is correct)

#61747 3D models for Netduino Plus 2

Hi Eriond.

I can't open your model. Can you make an IGES version?

#61638 Finding bytes in byte array

Posted by JBkey on 17 February 2015 - 09:19 AM in Visual Studio

Hi.

thank you for your answer.

You are right. I need to extract all the occurrences. About the end of block I know it's the 16th byte after the "0x55" occurrence.

I'm going to study your suggestion and I'll let you know what's my decision

PS. : How was the carnival? I hear that Venezian carnival is awesome.

#61614 Finding bytes in byte array

Posted by JBkey on 15 February 2015 - 09:15 AM in Visual Studio

It's like a little venezia,

Before I saw your comment I reached the same solution. And it's working so far.


                int index = Array.IndexOf(readBuffer, "0x55");

                byte[] results = new byte[16];

                Array.Copy(readBuffer, index, results, 0, 16);

But I forgot something...

In the source byte[] (readBuffer), I have more than one "0x55 block" and I need all of them (I didn't know this before, I thought it would be just one block per array).. and array.copy only returns the first one. Any ideas?

#61602 Finding bytes in byte array

Posted by JBkey on 12 February 2015 - 03:32 PM in Visual Studio

Hi!

I need some advice, and I think this is the right place, if it isn't, let me know.

I'm very limited on my programming knowledge, so maybe this is an easy question to answer.

I have an array of bytes that contains values like this:

byte [] values {00, 22, 33, 44,  0x55, 55, 66, 77, 88, 99, 10}

And I need to select a number x of bytes that appear after the 0x55 into another array (I only used hex to differenciate).

byte [x] selec_values { 0x55, 55, 66, 77, 88}

I thought I could search for that byte using "array.find" and I can't. Then I tried to build a list with the array values, and... again, I can't..

Does anyone know how I do that?

#61574 N+2, I2C, write to register

Posted by JBkey on 09 February 2015 - 05:36 PM in Netduino Plus 2 (and Netduino Plus 1)

Hi .

I'm a newbie. And I'm not quite a programmer, I'm starting with Netduino and with some help I managed to blink the Led and with Mario's help it's now communicating using modbus (thanks again Mario).

Now I have a new dilemma, I need to receive some data using I2C and writing it to a register. I've studied the code from
