Thank you Saurabh, we will think about developing our own electronics so to have full control.

Evaluation Tools / Re: Re-programming the Firmware on the Eval board
« on: June 09, 2016, 05:13:15 AM »
This board's typical use is for quick and easy evaluation of our displays, however if you wish to program it, you will need a compiler (we use Keil ÁVision4 IDE) and a JTAG programmer (we use the ULINK2).  You will also need to download the files from our website (http://www.newhavendisplay.com/nhdev/NHDev_Downloads.php) and load them onto the board using a program like ÁVision.


Hello Michael,

I need a few clarifications about the toolchain of the NHDev board.
We are looking for an evaluation board to start playing and making some experiments with one of yours TFT+touch displays, but so far I still don't know if the NHDev board is suitable for us.

1) Can the MDK-Lite tool by ARM be used to code, program and debug the STM32F103RE through the JTAG available on the board? As far as I know MDK-Lite is free but limited to 32KBytes code size, but the STM32F103RE has up to 512KBytes Flash.

2) Is the source code of your examples freely available to be used as reference for our experiments? I saw something here http://www.newhavendisplay.com/nhdev/NHDev_Initialization_Code.php but I'm not sure they are full examples.

Our goal is to buy an evaluation system with reference examples that we can play with and modify to show a customized "home" page with some icons that can be navigated through by touching them and opening new pages.
I would say a kind of "hello world" application for touch displays  :)


Thank you very much!

TFTs / Re: NHD-4.3-480272EF (TFT + touch) evaluation kit

Thank you Saurabh, the scenario now is clearer: the NHDev board can easily interface the TFT part of the NHD-4.3-480272EF, while the touch panel must be managed with an I2C port.

I have two questions in my mind:

- does the NHDev board have an I2C port available? Or do we need to connect the touch panel cable to our processor?

- in the last case, how can we communicate between our processor, that will retrieve the touch coordinates, and the NHDev board that sends the data to TFT display? Of course I'm thinking about the best way to get a full demo showing the TFT+touch interaction.


Thank you!

TFTs / NHD-4.3-480272EF (TFT + touch) evaluation kit
« on: June 07, 2016, 07:45:46 AM »
This is my first post, so hello to everybody here in the forum!  :)

We are looking at a TFT PCAP 4.3" display, in particular the family NHD-4.3-480272EF that seems very good for us (so far, no matter about brightness and viewing angle). This would be our first project with a TFT display.
From its datasheet, I understood it has two cables, one 40-pin for the TFT control and one 6-pin for the touch panel control, and this sounds ok to me.

What I would like to understand and do is to build, or to buy if available, an "evaluation kit" made of this NHD-4.3-480272EF touch display and some already-made electronics with some already-made example code to run and test both the touch and TFT performances.
Then we could start playing with this example to make our own piece of code, before starting designing our own board.

The big question is what should we buy to do this?

I saw there are some "controller boards" (NHD-4.3-480272MF-20 or -34) and a also "development board" (NHDev v2.0) with some downloadable examples, but from the datasheets I wasn't able to tell that the NHD-4.3-480272EF is supported (I saw only NHD-4.3-480272MF, but it has no touch panel), and actually I didn't see any mention to the touch management.

Could anyone give me some hints?


Thank you in advance!
Claudio
