What I can definitely see after investigation playing with stepping motor, there are delays in either changing status on pin or code interpretation

I was able to find delay I see progression, but it's definitely not enough

I am still working on shaman-ning it, I am almost there, If folks around will not find scientific solution, hopefully I would be able to give different delays and conversions

I am working right now with idea to figure out what's the real delay between NGO and SB
I believe if this one solved we almost there

Chris, I see incremental number while moving things further and excremental when going closer, but I can not tune exact number, I didn't yet figured out dependencies experimentally, but the same sonic sensor works great and gives exact calculated numbers with Arduino

Chris 1 question related to SB
I try to play with sonic distance sensor, one of the guys shared the code http://forums.netdui...ic-rangefinder/
I didn't try it with Netduino, but combination of NGO and SB doesn't give correct numbers, is there any specific delays or other could be the reson
PS: I tried the module with Arduino it works

No, was busy with other staff, I think Secret Labs staff help would be very useful, since it's 99.99% lateness issue, not sure if it because NGO connectivity or SB itself or both. But we should be able to get from them numbers to make calculations better

Hi!
TristatePort throw exception while construct via SB
here the code
ShieldBase sb = new ShieldBase((GoBus.GoSocket)1);
TristatePort p1 = new TristatePort(sb.Pins.GPIO_PIN_D2, false, true, Port.ResistorMode.PullUp);
here the exception
A first chance exception of type 'System.Exception' occurred in GoBusSerialTransport.dll
An unhandled exception of type 'System.Exception' occurred in GoBusSerialTransport.dll
Here the trace

Any ideas what's wrong?

Chris I personally first tried to dispose OutputPort with the exception, then I tried to use TristatePort, and get the same kind of unknown exception. I am just trying to play with CharliePlexing

Hi!
Anybody has experience SB with DFRobot L298P using HBridge, no errors motor doesn't rotate
Here the code
using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using NetduinoGo;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.NetduinoGo;
using Toolbox.NETMF.Hardware;

public class Program

public static void Main()
{
// write your code here
Thread.Sleep(5000);
NetduinoGo.ShieldBase sb = new NetduinoGo.ShieldBase((GoBus.GoSocket)4);
HBridge MotorDriver = new HBridge(sb.PWMChannels.PWM_PIN_D6, sb.Pins.GPIO_PIN_D7, sb.PWMChannels.PWM_PIN_D5, sb.Pins.GPIO_PIN_D4);
MotorDriver.SetState(HBridge.Motors.Motor1, -50);
//Thread.Sleep(Timeout.Infinite);

Thanks Stefan, I found the solution from absolutely different angle 
, but without your tip I wouldn't get it, it's somehow different MS, no PWM/PLL switch, and what happened it was different pins I will post later today pic of the shield, but it was shipped by robotshop.com in dfrobot wrappinf with df robot logo on it
Actually is there class to control stepper with it?

Solved by
Thread.Sleep(1000);
NetduinoGo.ShieldBase sb = new NetduinoGo.ShieldBase((GoBus.GoSocket)4);
Something wrong with all SB concept in new FW, I have also delay related problems with stepper and sonar range sensor

Actually, about disposal, what the quickest way to do it in NETMF? I am C++ person and C# and Java behavior make me always puzzled about it
#48661 Shield base pins reassignment

Question What happens if I open some D pin on shield base as output, then in some period of time reassign it as input?
Is it going to work? Does it require specific actions?
Thanks
