#53443 Shield Base Firmware (beta 7)

Posted by eplaksienko on 21 October 2013 - 07:25 PM in Netduino Go

Chris Tristate is great, will try to test it today.

1 more issue related to mis-synchronization NGO and SB, you need to put a thread.sleep before NGO initialized then it can initialize SB



#45927 Shield Base Firmware (beta 6)

Posted by eplaksienko on 20 February 2013 - 11:35 PM in Netduino Go

Folks, help please :(



#53440 Shield Base Firmware (beta 6)

Posted by eplaksienko on 21 October 2013 - 07:11 PM in Netduino Go

Is it possible to program SB with computer directly?



#45931 Shield Base Firmware (beta 6)

Posted by eplaksienko on 21 February 2013 - 02:53 AM in Netduino Go

Ok, it worked from bus #4

 

Chris, is there some reason?



#45930 Shield Base Firmware (beta 6)

Posted by eplaksienko on 21 February 2013 - 02:47 AM in Netduino Go

Chris thx, this worked, but then I got exception here in STM32Bootloader.cs

 

 

bool GetAck()
        {
            if (_isDisposed)
                throw new ObjectDisposedException();
 
            byte[] readBuffer = new byte[1];
            int bytesRead = 0;
 
            bytesRead = _serialPort.Read(readBuffer, 0, readBuffer.Length);
 
            if (bytesRead == 0)
                throw new Exception(); // timeout exception
 
            if (readBuffer[0] == 0x79)
                return true;
            else if (readBuffer[0] == 0x1F)
                return false;
            else
                throw new Exception(); // invalid byte
        }
 
The message
An unhandled exception of type 'System.Exception' occurred in STM32ReflashApp.exe . looks like similar to

#47384 Shield Base Firmware (beta 6)

Posted by eplaksienko on 19 March 2013 - 03:32 PM in Netduino Go

NGO with SB doesn't work independently on it's own power supply, Each time to start the app I have to connect to computer and load program from VS C#



#52870 Shield Base Firmware (beta 6)

Posted by eplaksienko on 23 September 2013 - 02:24 PM in Netduino Go

Chris, technically, how different SB and Netduino+?



#53441 Shield Base Firmware (beta 6)

Posted by eplaksienko on 21 October 2013 - 07:12 PM in Netduino Go

And also I think I burnt NGO, I used on SB DF Robot Motoroshield and when I used external batteries on motorshield (6V) it went craze with both NGO and SB. Any idea why?



#45896 Shield Base Firmware (beta 6)

#47306 SB with NGO much slower then Arduino

Posted by eplaksienko on 17 March 2013 - 09:32 PM in Netduino Go

Chris, in additional is there any hacks to send some more native way?



#47286 SB with NGO much slower then Arduino

Posted by eplaksienko on 17 March 2013 - 03:25 AM in Netduino Go

Hi!

 

may be I misunderstand something, but it seems me processing NGO with SB much slower then with Arduino, I am playing with step motor and I can see difference, I made everything easy, but still I can not get rotate it quicker, and signal lamps are just visible much slower then with arduino, may be there is any hack or anything I am doing wrong, the same code with arduino just fly. Any advise really appreciated

 

PS: I use Stepper Motor+ Driver Board ULN2003 5V 4-phase 5 line

 

 public class Program
    {

#47305 SB with NGO much slower then Arduino

Posted by eplaksienko on 17 March 2013 - 09:31 PM in Netduino Go

Chris, do you mean to send all 4 channels the same time, use 255 bit pwm to split, then I win x4?



#49195 OutputExpander - How to Make a Netduino GO! Module

Posted by eplaksienko on 07 May 2013 - 08:04 PM in Netduino Go

Mark, it would be nice to have it built similar to Arduino Mega, to accept ready to use Arduino modules



#45969 NGO to Gadgeteer module

Posted by eplaksienko on 21 February 2013 - 02:55 PM in Netduino Go

Hi Chris

 

Any news about NGO to Gadgeteer module?

 

Do you have already libs and examples for one you presented me on makers fare?

 

Thanks a lot

 

Eugene

Chris thx for update, I always feel discomfort with disabled toys :D

Alfred, they didn't announce anything yet



#48071 NEW MODULE: DigIO

Posted by eplaksienko on 05 April 2013 - 03:04 PM in Netduino Go

PS: What about interrupts?



#48083 NEW MODULE: DigIO

Posted by eplaksienko on 05 April 2013 - 06:06 PM in Netduino Go

Hi! Thanks 1st and 3rd I already realized what to do

About interrupts it would be great to have it since Shield Base doesn't solve problems with sensors like sonic range finder. If you get it working I would buy several of then :D

 

I think you would be able to do it somehow if you can control internal ones

Arron, are you going to publish for sell your modules?

 

Thanks
