Not Telling
I'm not aware of any SPI examples in VB. However, have you tried taking one of the C# examples and using one of the online convertors to translate the C# to VB? I believe Telerik have a free online service.

#65304 Netduino Plus 2 Firmware v4.3.1

In my experience, upgrading the firmware on the board tends to be the same for each board family and does not change between firmware versions.

#65192 ND3 cannot seem to create an interrupt handler
Posted by
on 14 June 2016 - 06:15 AM
I think you need you application to look something like this:
public static InterruptPort button = new InterruptPort(Pins.GPIO_PIN_D0, false, Port.ResistorMode.PullDown, Port.InterruptMode.InterruptEdgeLevelHigh);
public static void Main()
{
button.OnInterrupt += Button_OnInterrupt;
}
private static void Button_OnInterrupt(uint data1, uint data2, DateTime time)
{
throw new NotImplementedException();
}
The IDE generated the code for the interrupt and the attachment when I pressed the tab key following the +=.

After sleeping on this overnight I remembered that the Mono work is old and probably applies to the Atmel processors in the original Netduino boards and not the latest STM32 boards.

#64676 Forum was away from home for a while-- what happened?

As far as source code for Netduino, the code is here: http://www.netduino.com/downloads/But yeah it would be cool if there was a github project that we could contribute to. Maybe there is one, but I did a quick search and did not find it.
Some of the code is available on GitHubbut I don't think (I'm not 100% sure) that all of the code for all platforms is is there.

#64531 I2C strange behavior
Posted by

If the data sheet says the peripheral address is 0x40 then shouldn't you be using this in the .NET code:
0x40 << 1
The top 7 bits are used to hold the address of the peripheral, the bottom bit indicates if it is a read or write transaction.

Usual question with I2C - have you installed pull-up resistors if the board you are using does not already have them installed.

#64476 Minimum Vin Power
Posted by

I think you can power with 5V.
The barrel jack input is a minimum of 7.5V but the 5V header pin can take 5V. You just need to make sure you get the regulation right.

I am programming in vb.net. Is it possible to use your driver without converting it?
I know you can do this with standard C# and VB. I'd normally do something like:
- Create a new project in your VB solution with the C# code in it and compile the code to a DLL.
- Next make sure the C# code is CLS compliant. I think there is an attribute for this. Yes there is - add [assembly:CLSCompliant(true)] under your using statements. You will get errors if the code is not compliant.
- Reference the DLL in your VB project.
BTW - if you really need to convert the code then Telerik have a free online converter.

#64171 Interrupts
Posted by
on 21 September 2015 - 05:25 PM
It would be less processor intensive to use a timer to do this along with an interrupt which triggers on either a rising or falling edge.
So set up a timer which triggers every 100ms. This would just toggle the LED.
In your interrupt handler for J1pin4 you would check the edge of the interrupt. If it was a falling edge then you would enable the timer and return from the interrupt handler. If the interrupt was generated on a rising edge then you would turn the timer off.
Hope that makes sense,
Mark

Not really.
To be honest if I wanted a single pulse I'd probably look at a simple timer like the NE555 and see if I could trigger the start event from the Netduino.
Not sure if you could but that would be a starting point for me.

Nothing automated, just have to plough through the algorithm by hand.
