The code compiles without error, but nothing happens. Is there some obvious step that I am missing?

Hi,

use RoBoIO.rcservo_SetServo(0, RoBoIO.RCSERVO_SERVO_DEFAULT_NOFB) instead of RoBoIO.rcservo_SetServo(RoBoIO.RCSERVO_USECHANNEL0, RoBoIO.RCSERVO_SERVO_DEFAULT_NOFB);

also, rcservo_Close() will close PWM ouput, and so, after calling rcservo_SendPWMPulses(), you need to delay some time (or call rcservo_IsPWMCompleted(0)) to wait until all PWM pulses have been sent.

RoBoIO C# Dependency Errors

Sorry for the late response, I've been busy the past week.

The advice you gave me works great, I don't get any dependency errors anymore. Thank you.

However, I have a new problem. I am attempting rotate a servo using the rcservo library. The servo is a Futaba S3302. My servo control code is as follows

Code:: RoBoIO.rcservo_SetServo(RoBoIO.RCSERVO_USECHANNEL0, RoBoIO.RCSERVO_SERVO_DEFAULT_NOFB); RoBoIO.rcservo_Initialize(RoBoIO.RCSERVO_USECHANNEL0); RoBoIO.rcservo_EnterPWMMode(); RoBoIO.rcservo_SendPWMPulses(0,10000,1500,100); RoBoIO.rcservo_Close();

HI

1.Ensure that you have installed .NET Framework 2.0 & above on RoBoard.

2.You could try to download and install MS VC2008 runtime redistribution with correct version(non/SP1) on RoBoard.

Download MS VC2008 runtime redistribution:
http://www.microsoft.com/downloads/details.aspx?familyid=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF&displaylang=en

Download MS VC2008 SP1 runtime redistribution:

RoBoIO C# Dependency Errors

2010-03-27T22:52:25+01:00

I am attempting to use the C#.Net libraries recently released for the Roboard, and I cannot call RoBoIO commands. When I reference the RoBoIO function rcservo_Initialize I get an error message

"Unable to load DLL 'RoBoIO.dll': This application has failed to start because the application configuration is correct. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1)"

In my experience this error results because of an improper dependency in one of the DLLs. Perhaps I am wrong though. Is there something obvious I should be doing to resolve this issue. I have included RoBoIO_DotNet.dll, RoBoIO.dll, and WinIo.dll in the Debug directory of my program. Any advice anyone can give me is greatly appreciated.
