Hi,

 

I'm about to add a LCD display to my project (Netduino Plus 2) and I'm not sure which driver is best suited for my needs.

 

I will buy this LCD:

and this SPI/I2C backpack:

https://www.elextra....le&artno=H32320 (a Adafruit product: http://www.adafruit.com/products/292)

 

It seems like there is drivers from both http://netduinohelpers.codeplex.com/ and http://netmftoolbox.codeplex.com/, but I'm not sure which one is best suited or if I should go for a third option?

 

Anyone care to share their experiences using a LCD with a backpack?

Hi CW2,

 

Thank you for the feedback.

It seems I might be a bit over my head in this

Hi,

 

My small Philips TV broke (DVD drive malfunction), and upon disassembly I found a AUO a085fw01 v7 LCD panel inside.

From the datasheet (  a085fw01 datasheet.pdf   908.1KB   4 downloads), it looks like quite a job to get it to do anything meaningful

 

How would I go about using this with a Netduino, is it even remotely possible for a hobbyist like me?

I believe I would need some sort of controller and a .netMF driver (can these be some kind of generic or does it have to be tailor made for the specific panel)?

 

Lots of novice questions  I just want to know if I should put the LCD in the thrash.

Hi Frode,

I just got the "real" one from @Ferocildo, he was nice enough to send it to me.

Attached to this post is the article and the driver.

• Driver solution:  LoveElectronics.zip   471.4KB   49 downloads
• Article:  Article.zip   1.15MB   40 downloads

(Chris can you make this the answer of the thread?)

Now if you look at the site again you'll see that the original code is also shown. You can copy and paste the code into your Visual Studio project. The missing one will be generated for you. And typically the code also contains indicators as to how the hardware is driven.

Hi Dr Who,

 

The code shown in the article says this:

Add this line of code to the top of this file:

using LoveElectronics.Sensors.Accelerometers;

In the Main() method, remove the code we wrote before, and replace it with this:

ADXL345 accel = new ADXL345();
if (accel.EnsureConnected())
{
Debug.Print("ADXL345 was found!");
}

 

This still leaves me missing the ADXL 345 Library shown here:

 

 

Thank you for trying to help me, but I'm still stuck until I find someone who has a copy of the library/solution for the ADXL 345 accelerometer.

Hello!

As I recall the site concerned itself with the ADXL335, not the ADXL345. Are you quite sure that the original site did concern itself with the ADXL345?

 

The title of the article is "Accelerometers: ADXL345 Library and Netduino Tutorial" (https://web.archive....how-to-use-them).

And the article refers to the "LoveElectronics.Sensors.Accelerometers.csproj" project not "Netduino_Accelerometer" like the zip-file you posted.

Hi Dr Who,

 

Your attachment does not seem to include what I'm looking for. I don't see any I2C setup and it is for the ADXL335, not ADXL345.

But thank you for helping.

 

I did find the original article here:

https://web.archive....how-to-use-them

 

But the download link is still broken, clicking "Download Now" does nothing:

https://web.archive....FyeS1WMS56aXA=#

 

 

So my question remains, does anyone have a copy of the "Love Electronics Accelerometer Library V1"?

They refer to it as "LoveElectronics.Sensors.Accelerometers.csproj" in the article.

Sure, you can download it from here.

 

Great, thank you! 

Hi Frode,

 

Thank you for the quick reply.

 

I have will have a look at the SSD1306 driver, you wouldn't happen to have a source file that isn't garbled?

Hi Frode,

 

Great work on the driver

 

I'm trying to convert your driver for use with my ADXL345 (http://www.adafruit.com/products/1231), and I want to use it with I2C instead of SPI.

From what I can see I need to rewrite all the SPI methods and the ADXL362Accelerometer method, for use with I2C.

 

Would I be so lucky that you have some experience in creating I2C drivers?

Hi,

 

I'm trying to get my ADXL345 accelerometer working with my N+2.

 

I see a lot of people referencing a tutorial found here: https://www.loveelec...how-to-use-them

The driver should be downloaded from here: https://www.loveelec...mFyeS1WMS56aXA=

 

But the site is down , and I was hoping someone could provide me with the/a driver?

I have found this blog post about connecting a 12V LED strip to a Arduino:

http://blog.dcxn.com...ith-an-arduino/

 

It's seems like a TIP120 NPN Darlington transistor will do the job, but is it he best choice?

 

I also finally found a setup using the ADXL345 with I2C, describing the connections:

http://bildr.org/201...dxl345-arduino/

 

Now I just want to be sure the batteries is okay to power the Netduino and the LED strips?

 

Lastly, should this post be moved to the "General Discussion" is it might now be very N+2 specific?

Hi Netduino folks!

 

I'm a hobby programmer who have just ordered a Netduino Plus 2 for my first electronics project in 15-20 years.

So please bear with me if too many of my questions are really basic knowledge, and as a non-native English speaker I'll try my best with the technical terms

 

Here's a quick resume of my project:

• I want to control two LED strip using the Netduino.
• One of the strips will light up differently based on input from a accelerometer (the top one in the image bellow).
• All the components will be powered by batteries.

The whole project is for my cargo bike, having the rear light respond to braking/stopping the bike.

 

That is pretty much it, I have made i crude drawing off the components here:

 

I know the accelerometer can be powered by the 3.3V output from the Netduino, but the connection guide most refer to is at "www.loveelectronics.co.uk" which seem to be closed down.

Further I know that the LED strips need a transistor to be controlled by the Netduinos PWM ports. But again I'm not sure how it should be wired up and which components to use.

 

So to sum it up, I hope for some guidance with the following:

• Is the 8 D cell batteries suitable for my setup, i.e. will they be able to power the LEDs?
• From what I have read the Netduino is able to handle up to 18V on the Vin. Will it cause any issues using 8 x 1.5 batteries as a power supply?
• Should I use a MOSFET, PNP or NPN transistor for the LEDs? And which model would be most suitable?
• How do I wire up the accelerometer to the Netduino? Are any resistors needed?
• Anything else I'm missing?

Please ask away if you have any questions!
