G400HDR & G400-D Pins

NETMF & Gadgeteer
1

I was going crazy flipping back and forth looking through G400HDR_Breakout_SCH.pdf and G400_Module_Brochure.pdf trying to map to CPU Pins…

Well I bit my tongue and made a list… I’ll share if you need/want it.

I do not know of a way to post a text file in here so I will try Format as Code. I believe you can just copy and paste the text when you view this post.

Let me know if you find any errors…!!!

@ willgeorge - I just commented on another post that they could use the code for the G400HDR Mainboard to get the mapping. BUT, this is 1000x better, thank you for sharing!

It might be worth including a comment on socket 6 indicating that it uses SPI module 2, the pin designation can mislead one to think it is SPImodule 1

@ Aron, this list might be nice to include on th developer page for the G400HDR.

@ taylorza - Thanks for your code!

I do have a question about using it with a Distance US3 … Maybe you know the answer.

Sorry if this is not the proper place to ask…

I cannot attach a Distance US3 to my G400HDR/G400-D

In Program.generated.cs - Main(), InitializeModules() I receive:

Invalid address 22706930 and range 4 Ram Start 20000000, Ram end 20100000

private Gadgeteer.Modules.GHIElectronics.Distance_US3 distance_US3;

Error here > this.distance_US3 = new GTM.GHIElectronics.Distance_US3(6);

I have tried Sockets 6 through 9 and I receive the null error on each socket.

I know the Distance US3 is OK because it works on my Spider.

Any suggestions?

@ willgeorge - I believe you might have found a bug in the port? It seems that when configuring an IO pin’s pull-down resistor this exception is generated.

Try the following in a straight .NETMF application for the G400.

This works:


var port = new InputPort((Cpu.Pin)26, false, Port.ResistorMode.PullUp);

This fails with the same exception you are seeing


var port = new InputPort((Cpu.Pin)26, false, Port.ResistorMode.PullDown);

GHI will need to confirm, but looking at the data sheet the MCU supports pull down configuration on PIOA so I do not see why it should not work other than it being a bug.

BTW. pin 26 is PA26 -> Pin 3 on Socket 7. Pin 3 is used in the distance module driver capture the echo.

@ taylorza -

Thanks for the quick reply…

I will try tomorrow… Off to babysit my granddaughters in a bit…

Now that you mention it, I had the problem before and made a note to myself…
I forgot all about it

//Exception when using Port.ResistorMode.PullDown
Socket9Button = new InterruptPort((Cpu.Pin)G400.Pin.PB18, false, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeBoth);

Babysitting called off. Parents changed plans…

I was looking at the Distance_US3_42.cs driver file and I see…



/// <summary>Constructor</summary>
/// <param name="socketNumber">The socket that this module is plugged in to.</param>
public Distance_US3(int socketNumber)
{
    Socket socket = Socket.GetSocket(socketNumber, true, this, null);
    socket.EnsureTypeIsSupported(new char[] { 'X', 'Y' }, this);

    Echo = new GTI.DigitalInput(socket, Socket.Pin.Three, GTI.GlitchFilterMode.Off,
                                             GTI.ResistorMode.PullDown, this); 

    Trigger = new GTI.DigitalOutput(socket, Socket.Pin.Four, false, this);
}

I think I’ll play around and see if I can modify Echo
by changing the GTI.ResistorMode.PullDown and get it to work.
(Not change the official driver) Just use the code (modified) locally in my application…

Sounds like fun!
