@smartgirl:
Are you translated mikroC to C#.net?

pic18f452

I have pic18F4525

The code is written in C, for PIC (P18F452)

Nope! it is written in mikroC.

Hi smartgirl,

Your project isn't written in C# or VB.NET. What kind of microcontroller do you use?

It written in mikroC language. The latest is mikroC PRO.

I believe the original idea is about toys (i.e. small scale vehicles), not *real* cars.
Very interesting, though. I hope this kind of projects won't trashed in this period of very bad cars' marketing.

NOTE. "RF" stands for Radio Frequency, so...theoretically *ANY* radiation-based link is RF. However, it commonly stands for frequencies ranging from some kHz to many GHz. Light, heat, and similar are not considered "RF", although they are radiance-based.

Cheers

I see you talking about toys not real cars.So sensor you are looking for HY-SRF05 or later. You can sourcing from China. It is very cheaper and wifi module too.
Mario, don't worry about me.....I'm electronics tech engineering

@stefan.
Very sorry

I was watching a show on learning robots the other night and they had these little robots using NFC to communicate. This way the robots only exchanged information when they came near each other. It was a social experiment to see if the robots would learn to socialize.

I have seen on tv on discovery channel and nasa channel. For v2v, there are using wifi device designed by Australian in 2007. The wifi usually from laptop It is not RF devices. There is special device for sensor ranging up to 1000m. The cheaper sensor are not allowed in automobiles. They are using arm11.

Btw, I'm switching back to old file 4.2.0.2

In the meantime, if you need to update your Shield Base to beta 4, we have a quick workaround:

• Flash your Netduino Go with the 4.2.0.x firmware

Where can i find 4.2.0.0 or 4.2.0.1?
Or Better wait new beta5

Woot! A Netduino Plus 2!

Hi Stefan,
R u using 2x74HC595?

Really? Everything for $2? I'll buy yours!

Serious

I havent seen a dedicated "for sale" area of the forums (if it exists, I apologize for being too clumsy to find it)

But if anyone is interested, I have the following essentially new items on ebay at the moment (or for sale) for significantly below regular price

Nwazet LCD Touch Screen Module (I have 2, Only selling 1)
Netduino Plus (I have a Go! and decided to use that)
Parallax Propeller Board of Education (8-core super dev board in a BOE form factor)

I will also note that I am including random goodies with each thing.

If posts of this kind are frowned upon, or need to be moved elsewhere, please let me know.

-Mike

Yeah! I was considering going to sell mine too. Everything for $2 including Go and Nwazet LCD and ShieldBase and some other accessories too

Hi supra,

thanks for the link to loveelectronics tutorial. I have used used this tutorial before the library they have put together is excellent and I also highly recommended it.

The issue isn't with how to write the code for the i2c device but that the device is not working with NP2! for that matter I can't get any device to communicate via I2C with my new NP2!

have you implemented an I2C devices with the new NP2?

I'm using NGo. But i will get one by xmas
Mlink

I just got my NP2! thanks for making such an awesome update!

I'm not able to get the I2C to work with my ADXL345 connected to the new SC/SD connectors?

I'm running the following code:

Byte[] _data = new byte[1] { 0 };

I2CDevice adxl345 = new I2CDevice(new I2CDevice.Configuration(0x53, 400));
I2CDevice.I2CWriteTransaction write = I2CDevice.CreateWriteTransaction(new Byte[] { 0x00 });
I2CDevice.I2CReadTransaction read = I2CDevice.CreateReadTransaction(_data);
I2CDevice.I2CTransaction[] actions = new I2CDevice.I2CTransaction[] { write, read };
adxl345.Execute(actions, 1000);
Debug.Print(_data[0].ToString());

I'm running the same code on my NP1 connecting to A4/A5 pins and the device is working but not on the NP2.

HELP PLEASE!

I erased 20 times.

Switching back to 4.2.0.2 fine with me.

It my NGO is virus?

Are you sure?, also if you scope the PWM class?

That is, doing this:

  leds[0] = new PWM(Microsoft.SPOT.Hardware.Cpu.PWMChannel.PWM_0, 100, 1, false);

This one is better. W/out using namespace
leds[0] = new PWM(Cpu.PWMChannel.PWM_0, 100, 1, false);

Hi Supra,

it works with 4.2.0.0 and it may work with 4.2.0.2, the issue however is to use the NWAZET screen under 4.2.1.x ;-)

Have you tested it under the new firmware?

Cheers

Andi ;-)

Yes. I have tested 4.2.1.0 to use nwazet LCD

Hi Supra,
What is 4.2.02?

Cheers

Andi

OOp! Sorry. My mistaken. It is 4.2.0.2

Hi Supra,

We need to post an updated reflash app for Shield Base. We're working on it.

In the meantime if you want, you can load the _older_ Netduino Go firmware and reflash your Shield Base...and then upgrade your Netduino Go mainboard to the latest firmware.

Chris

The problem is when i deployed ur sln.is asking for gobus.cs. So i had deleted ur old gobus.dll and added new gobus.dll with same firmware 4.2.01. And had to started all over again and still had throw exception for output[]...... Anyhow, I added new firmware 4.2.02 and that solved my problem.

Hi Chris,

meanwhile we have re-added GoBus.dll and nothing has changed, neither NWAZET screen nor serial comm are working.

Could you please let us know what was changed in the firmware? At least it would be great to see the debugger telling us what goes wrong ;-)

Also it would be cool if you could test all core functionalities before releasing a new firmware (sorry, I dont want to offend or to annoy anybody, as we see that you are doing a great job)

So far, the new firmware release is a phantom for our developers as the code stopped working ;-))

Cheers

Andi ;-)

Did u download new firmware 4.2.02? My nwazet LCD still working

hmm, thats strange.

I also deleted the GoBus.dll reference, and readded. I uninstalled the old SDK before installing the new one.

What version is your GoBus.dll? Mine is 1.0.0.0, created Nov. 7 2012, 02:43 (might be my local time)

I downloaded today same link as above frm Chris

In my debug window...Assembly: GoBus (1.0.0.0).
U don't need installed SDK over and over again. Wait until new firmware as Chris mentioned b4

So far I can deploy many times w/out plug/unplug frm usb.

If someone got the display module from nwazet, could u please do me a favor and test it with this firmware?

My application hangs when initializing the module.

edit: still having trouble deploying to the Netduino Go..

I tested new firmware today. Mine is ok. I deleted old gobus.dll and add new one
