Character LCDs / NHD-0220D3Z-NSW-BBW-V3 using I2C dropping characters
« Last post by bwendin on Today at 12:22:59 AM »
We need to control our NHD-0220D3Z-NSW-BBW-V3 with I2C and running at 100kHz (which it says is supported in the datasheet), I see it drop characters.  It seems to drop about one character out of 3 or 4 every time if I send all 20 or 40 with one I2C command.  I looked at the waveforms on a logic analyzer and an oscilloscope and everything looks healthy.  By the way, I'm an I2C expert so I know what healthy looks like.  We are a real company planning to use this display in a production product shipping in Q4 2018.   We just had to switch from UART to I2C after choosing this part and it is hard for us to change at this time.  Any answer as to why it isn't working?   Do I need to run a slow I2C clock (I tried running at 50kHz and it works fine).  But I'm controlling about 5 other parts on same I2C and don't want to run at 50kHz.

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...

Works:
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 »
Hello,

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.
Regards

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: http://www.newhavendisplay.com/nhd_catalog.html

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

Thanks and Best Regards,
Ted

I have answered my own question. 

On page 3-1 of this doc https://www.e-sonic.com/Upload//LeaderBoard//c32e6567-1330-4e81-a72d-a50b0ca7d645.pdf  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:  http://www.newhavendisplay.com/nhdev/specs/NHDev_v2.pdf

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.
