OLEDs / How to use variables
« Last post by BumpSplat on June 20, 2018, 03:42:15 PM »
Part Number: NHD-0216MW-SB3

I'm clearly missing something here.  I can't seem to successfully write a variable to my display.  I can successfully write an explicitly defined character but can't seem to get a variable to work...

update_display.bottom_row[7] = '1';

Doesn't work:

    char        character  =4;
    uint8_t    var           =5;

update_display.bottom_row[7] = character;
update_display.bottom_row[7] = var;

what am I missing? :)

Thanks in advance!

TFTs / Windows CE 7.0 Touch Driver for NHD-7.0-HDMI-N-RSXV-CTU
« Last post by eudoxos on June 19, 2018, 01:28:46 AM »

has anybody experience with touch drivers (NHD-7.0-HDMI-N-RSXV-CTU) for Windows Compact Embedded 7.0? The operating system cannot identify the touch controller IC (PIC18LF2550).
Are there any drivers/libraries for download?
The touch controller works well with Win 10 / Win 7, that means the hardware is ok.

Thanks a lot in advance.

Hi Steve,

It's good to hear you have found the answer.
The latest version of our product catalog referenced in your post can also be found on our website here:

The NHDev board supported display listing is on the same page 3-1.

Thanks and Best Regards,

I have answered my own question. 

On page 3-1 of this doc  it indicates that the NHD-1.8-128160EF-CTXI#-F is indeed suported by the NHDev board.

I have not yet purchased the development board.

My query stems from looking at the online datasheet for the NHDev:

On page 2 it lists the supported displays. The only 1.8" one listed there is the NHD-1.8-128160TF-CTXL#

Can you tell me when you purchased the NHDev Development board?

It seems that you have an older version of the software. the NHD-1.2-128160TF was an older model we used to sell and has been replaced by the NHD-1.8-128160EF series.

Thanks for posting the drivers for the Rasberry Pi!  They will be very useful for many users. 
We look forward to seeing more of your postings in the future.

So after the FPGA drivers I went for something easier, and connected the TFTs to the Raspberry Pi's GPIOs.

Repo for the NHD-1.8-128160EF TFTs:

Repo for the NHD-2.4-240320CF TFTs:

Both drivers are native C, they map the main display's internal framebuffer (/dev/fb0) to memory, read the pixels' RGB values and bit bang them to TFT via the GPIOs.

The frame rates are ok, about 20 fps on the 2.4" and 34 fps on the 1.8" display.

I would like to use the NHDev module to evaluate a NHD-1.8-128160EF-CTXI#-FT display.

However, in the list of displays that the NHDev supports, it lists only NHD-1.8-128160TF-CTXL#, which appears to be a bogus number, ie it shows no results if we search for it on the Newhaven site.

Can anyone confirm if the NHD-1.8-128160EF-CTXI#-FT will work with the NHDev module?

Alright, the MADCTL issue is resolved - I connected the other 1.8" TFT I have here (a NHD-1.8-128160EF-CSXN#) and MADCTL is working as it should, so I removed the workarounds from my code.
