TFTs / Re: Windows 10 IoT Core
« on: October 10, 2018, 03:27:39 PM »
Unfortunately, its a limitation of this type of touch panel 
For the best edge to edge touch performance it is highly recommend to use the Capacitive Touch version (if possible):

Hi,
The AR1100 (Resistive Touch Screen Controller IC) shows up like a USB mouse, it works on all operating systems as the computer doesn't know it's a touch screen, it just thinks its a mouse. You can adjust the AR100 to consider itself a Touch Digitizer, supported by many but not all computers.
If you have a Raspberry Pi available you may re-calibrate the touch IC via USB using the following program:
https://github.com/tom-2015/rpi-AR1100
or
If you have a Windows computer you may re-calibrate the touch IC via USB using the following program:

Hope this helps,

Character LCDs / Re: NHD-0220D3Z-NSW-BBW-V3 using I2C dropping characters
« on: July 02, 2018, 09:57:10 AM »
Hi bwendin,
I’m sorry to hear about the trouble you are having with the NHD-0220D3Z-NSW-BBW-V3.
There is a known issue on our serial LCD modules which affects its operation when used in I2C mode.
When using the module’s I2C interface at a clock rate of 100KHz NACKs/bit errors/hanging, may occur.
Therefore, if using the I2C interface of these serial LCD modules, a MAX clock rate of 50KHz should be used.
We have updated the I2C section of our datasheet to reflect this information, and the updated specs should be accessible on our website shortly.
If you have any questions or need any assistance getting these serial LCD modules working, please contact us by emailing our technical support email nhtech@newhavendisplay.com, or by calling our phone M-F, 8am - 5pm CST (number listed on our website in the contact us section), we're always happy to help!

Hi warriorofwire!
I’m sorry to hear about the trouble you are having with storing / displaying Paletted8 bitmaps.
FTDI has an application note for image file conversion (see page 14):
http://www.ftdichip.com/Support/Documents/AppNotes/AN_303%20FT800%20Image%20File%20Conversion.pdf
Regarding the palette / index scheme of FTDI's image converter tool it may be beneficial to seek support from their support team directly.

OLEDs / Re: NHD-2.7-12864UCY3 replace to previous version
« on: May 29, 2018, 08:13:40 AM »
Hi Zsolt,
The Newhaven Display 2.7” Monochrome Graphics OLED module, NHD-2.7-12864UCY3, has reached End-Of-Life and is being replaced by our new and improved 2.7” OLED module, the NHD-2.7-12864WDY3.
The new module has been designed to match the physical dimensions of its predecessor, and will fit into any existing housings/enclosures used currently. However, due to the current OLED panel’s built-in controller being discontinued, the new module will not be a drop-in replacement.
A product EOL (End‐Of‐Life Notification) was sent out on June 8, 2017.
If you are interested in received the Product EOL/Replacement Transition Guide, please see the link below:
http://www.newhavendisplay.com/docs/NHD-2.7_Transition_Guide.pdf
The purpose of this document is to highlight and explain the key differences that need to be accounted for when transitioning from the ‘EOL’ to ‘NEW’ 2.7” Monochrome Graphics OLED module from Newhaven Display.

OLEDs / Re: NHD-3.12-25664UCY2 display - inconsistent pixel brightness in same areas
« on: May 24, 2018, 11:43:47 AM »
These OLEDs are passively drawn, which means that each line is lit at once. If you have a line with almost all the pixels lit it wont be as bright as a line with only 50% or less lit up.
