#38269 Shift-Register Problem - Turn led's on

Posted by supra on 31 October 2012 - 02:52 AM in Visual Basic Support

I'm using NGo. There is no need to add resistors. The TTls can handle up to 20mA. There is something wrong with code.. I can only do short code in order to reduce file size.

#37842 Read / Write Port by byte via Tris

Posted by supra on 23 October 2012 - 12:53 PM in General Discussion

How can I read and write the Tris ports via a byte. Common functionality on most micro controllers however I can not figure it out on the Netduino.

Arduino example:
DDRB = 0xFF; // Set PortB to outputs.

In Netduino:

static OutputPort[] DDRB_8 = new OutputPort[8];

DDRB_8[0] = new OutputPort(Pins.GPIO_PIN_D0,True);
:
:
:
DDRB_8[7] = new OutputPort(Pins.GPIO_PIN_D7,True)

In PORTB = 0x00; // Set all pins to low(clear all PORTB). U don't needed to do this

Hope that help!

#37468 Having a problem with my adafruit ST7735 LCD

Posted by supra on 20 October 2012 - 01:33 PM in General Discussion

Hi Rico/Supra,
I am not able to get anything when I map rest, D/C and TFT_CS to the above pins. Can I use these alternate GPIO pins. Please help!

Sorry for late reply. Btw, I'm using NGo.
There is no way to make thing work if u used alternate GPIO pins.
Double check ur wiring(some not getting signal) probably.

#37298 LCD for beginners

Posted by supra on 17 October 2012 - 12:45 AM in Netduino 2 (and Netduino 1)

Hello guys. Could you suggest me cheap LCD to work with Netduino. Without soldering. Just plug to Netduino or breadboard and play with it. There are a lot of this stuff on eBay. I don't know which one is fully supported.

Here is link fom ebay:

#37276 A first chance exception of type 'System.Exception'

      serial.Open();

Never mind. I solved problem

#37246 A first chance exception of type 'System.Exception'

Posted by supra on 15 October 2012 - 07:55 PM in Netduino Go

@chris
If you scroll up to see my previously posted

w/out using system.io.port;

I got error while deployed NGo
And the breakpoint : static ShieldBase sb = new ShieldBase(GoSockets.Socket5);
The error:
A first chance exception of type 'System.Exception' occurred in GoBusSerialTransport.dll
An unhandled exception of type 'System.Exception' occurred in GoBusSerialTransport.dll

Now, I followed ransomhail. And adding using system.io.port;
The problem is i got 2 red underlines: Serial.Open(); <== but why is capital letter "S" instead of "s"?

Thank

#37243 A first chance exception of type 'System.Exception'

Posted by supra on 15 October 2012 - 07:35 PM in Netduino Go

Could you explain me what you mean with "pb"? Or type whole words? That would help us help you.
I -think- I figured out frm is "from".

Sorry about that.
pb = problem
frm form
abt = about
AfAIK= as far as i know
brb = be right back
That was dating back in 1984 when the internet came out.

Posted by supra on 15 October 2012 - 03:31 PM in Netduino Go

Have you upgraded your Shieldbase firmware to beta 4 and remembered to remove the old NetduinoGo.Shieldbase.dll and added the newer version?

YEP!

how do i write button on NGo board to reset it? inputport button = new InputPort(Pins.ONBOARD_SW1, false, Port.ResistorMode.Disabled); Btw could be? var button = new InputPort(Pins.Button, false,Port.ResistorMode.Disabled);

#36900 The GoBus Upgrade

Posted by supra on 09 October 2012 - 07:34 PM in Netduino Go

Hi supra,

There are some Gadgeteer modules that have led matrixes. You can connect a few together. Please make sure to check the power consumption of them first; some of them may require an additional power supply.

Chris

Yeah! I know abt it.
Thank.

#36893 Nwazet Go Pro Kit

Posted by supra on 09 October 2012 - 06:43 PM in Netduino Go

Why would you destry it with dymo tape? the laser etching Fabien writes about should be enough.

the thing is i don't like board layout. It looks bad to me. I like apple designed board layout for Fabien.

#36892 The GoBus Upgrade

Posted by supra on 09 October 2012 - 06:37 PM in Netduino Go

(like an module with only one 8x8 matrix, that would be extremely expensive if one would like to drive more than one matrix.. )

Yeah!

. I haven't gotten answer frm chris Posted Image

. That the way i don't like to add an extra module. I was going to 15 - 20 servo motor to build robot.
the board is too big for robot.

#36888 All Nwazet assemblies in one archive

Posted by supra on 09 October 2012 - 06:21 PM in Netduino Go

But not so many of the popular ones are Open Source, and made by the guys who made Winamp.

Quite impressive, and proof that Open Source can be the answer.

- Ulrik

After yr 2000, some r discontinued and Open Source code came around in 1997, but i cannot recalled Posted Image

#36886 Nwazet Go Pro Kit

Posted by supra on 09 October 2012 - 06:12 PM in Netduino Go

Supra, and ruin the nice shiny black acrylic plates?! I guess if you wanted to you could add your own Dymo labels after the fact. To each his own I guess

Steve

HHHMMMnnn

That cost me around US$250 + $$$$(Dymo labels) total around $US300 Posted Image
