TFTs / Re: Nv3035 driver code
« on: April 12, 2016, 08:28:38 AM »
Correct, the NV3035C is the displays built in driver. The SPI interface may be used to modify various registers, see page 19 in the drivers datasheet for the full "Register Table".

Please note that no initialization via the SPI interface is required to get the display operational. By default the display is configured to achieve optimal settings.

The NV3035C datasheet will list in detail how to properly communicate and set various registers. Unfortunately we do not have any example code available, however it is just communicating via 3-wire SPI.

Morning Jack,

First to enter the RS‐232 mode, both R1 and R2 should be open.

Second, can you please confirm you are matching the displays BAUD rate? By default the BAUD rate is 9600, and is changeable with a command function.

Third, can you please verify that the data being sent to the display is being sent LSB or MSB?

TFTs typically have a digital RGB interface (essentially digital VGA) and are simply LCD panels that require pixel data (RGB data bus) and timing/synchronization signals (HSYNC, VSYNC, pixel clock).
Using a TFT with a TFT controller, such as the SSD1963, allows for a standard MCU type interface (8/16 bit parallel data bus, control signals such as command/data selection, active LOW write, etc.)

The TFT controller outputs the necessary 24bits of RGB, and the timing signals for you.  Some development boards / microcontrollers have TFT drivers/controllers built-in, and would therefore not need an external TFT controller such as the SSD1963.

I recommend you reach out on STMicroelectronics forum / support page, I'm sure they will have some app notes available for the stm32f4.

Burn-in (as in ghostly image) is more susceptible to OLED displays, however it can still occur with standard LCD's.

The length of time required for noticeable screen burn to develop varies due to many factors. It can take as little as only a few weeks for noticeable ghosting to set in, especially if the screen displays a certain image (example: a menu bar at the top or bottom of the screen) constantly, and displays it continually over time.

Please note that screen burn-in can easily be avoided, you may want to think of a plan to reduce long-term display in the same place on the screen.

Below are a few simple steps you can take to prevent burn-in:

E.g. In your case maybe install a PIR sensor to turn off the display when no one is in proximity of the unit.

E.g. Enable the OLED's built-in scroll feature.

Not a problem Amit,  "SDIN" stands for Serial Data In

e.g. MOSI

Enjoy your new display!

Morning Fahad,

Thank you so much for sharing! Can't wait to try out your example code on the NHD-2.4-240320CF-CTXI ;)

Have a great weekend!

Morning Cacio,

Iím sorry to hear about the trouble you are having with NHD-C12864LZ-FSW-FBW-3V3. All displays are tested before they leave our facility, chances that it is DOA is fairly low.

I looked over your schematic and found a couple issues that need to be addressed, please see the photo attached.

Morning John,

Thank you for reaching out! I'm sorry, unfortunately I do not have any guidance on the proper settings for the S1D13517 registers.

It might be beneficial to reach out to EEPSON with this request, typically they will have Apps notes available.

Morning zleo!

Any chance you would be able to post your initialization sequence?

Morning Pierre,

The photos defiantly help, it appears you are utilizing an older Rev of NHD-5.0-800480TF-ATXL#-CTP.

Your display stock will be configured the following way:

Defaulted as SYNC mode, and its PCLK latched data on the rising edge.

R7 & R8 are what changes the mode.  It comes default as R7 open and R8 shorted.  To change to DE+SYNC mode, R7 needs to be shorted and R8 needs to be open.

R9 & R10 are what changes the PCLK polarity.  It comes default as R9 shorted and R10 open.  To change the PCLK polarity to falling edge, R9 needs to be open and R10 needs to be shorted.

Morning Pierre,

NHD-5.0-800480TF-ATXL# uses the OTA7001A source driver and OTD9960A gate driver, is defaulted as SYNC mode, and its PCLK latched data is on the rising edge.

To change to DE+SYNC mode, R17 needs to be shorted and R18 needs to be open. It comes default as R17 shorted and R18 open.

To change the PCLK polarity to falling edge, R19 needs to be shorted and R20 needs to be open. It comes default as R19 open and R20 shorted.

Based on what you are experiencing with the blinking pixels it sounds like you need to change the PCLK polarity to falling edge.

Hope this helps!

Hello emax73,

Can you please send me a couple photos / short video to help trouble shoot?
