OLEDs / Re: NHD0420CW-Ax3 display with Arduino Uno - Tutorials
« on: October 20, 2015, 07:46:58 AM »
In order for you to send the “Set Contrast Control”  command RE and SD must be set to 1, please see the attachment.

E.g. The following commands set RE – SD  to the appropriate values before setting the contrast.

command(0x78);
command(0x2A);
command(0x79);             

I recommend you review the US2066 datasheet, this will give you a better understanding on how to send commands.

Hope this helps  ;)

Accessories / Re: Captouch TFT bexel mount
« on: September 29, 2015, 11:34:10 AM »
Hello Graham,

The same design details can be applied to the CTP panel, as always be sure to consult with the displays datasheet.

It will list vital information such as the capacitive touch panel material characteristics and other useful information which should be taken into account.

Hope this helps!

Glad to hear you got your display up and running!

Thank you for sharing your solution  ;)

Hi Alias,

When prototyping I highly recommend you focus on one section at a time, there's a lot to cover in your post.

First I would suggest trying to get your display operational in 16bit mode (default state when using the BB-BONE-LCD7-01-00A3.dts) and verify that your overlay has loaded / configured correctly.
It would also be helpful to see your boot process if possible. To see the actual boot process a RS232 cable like the TTL-232R-3V3 from FTDI is needed. Just plug it into the J1 connector (located on the BBB) and open a serial terminal of your choice.

Second when posting a pinout table please be sure to include the pin numbers from the display to the BeagleBone Black.

e.g.
Display :                                BBB
Pin  1       : LED-                    --> P8_3


Finally, it is extremely difficult to verify if your back-light circuit it correct without a schematic / wiring diagram.

Hi Robin!

Thank you for the information, it appears there is an issue with your data lines (RGB Data Signals).

Can you please confirm that you are grounding the LSB's on our display when using 16bit mode.

E.g.

R0  -GND (LSB)
R1 - GND
R2 - GND
R3
R4
R5
R6
R7
R8 (MSB)

G0  -GND (LSB)
G1 - GND
G2
G3
G4
G5
G6
G7
G8 (MSB)

B0  -GND (LSB)
B1 - GND
B2 - GND
B3
B4
B5
B6
B7
B8 (MSB)


Finally, can you please post the datasheet for the Truly display so I can look it over  ;)

Thanks!

OLEDs / Re: NHD-1.5-128128UGC3 + Beaglebone Black
« on: September 24, 2015, 08:14:33 AM »
Hi Parsec!

A great place to start is by viewing our example Arduino code:

https://github.com/NewhavenDisplay/NHD-1.5-128128UGC3_Example/blob/master/examples/test/test.ino

You will need to modify the initialization sequence in the BBB iolib to match the NHD-1.5-128128UGC3 parameters.

Be sure to have the NHD-1.5-128128UGC3 example code open and scroll down until you see the "Initialization Start", see lines 1055 - 1106 and modify the appropriate files in iolib  ;)

Hope this helps!

Hello chughes!

I’m sorry to hear about the trouble you are having with NHD-0420D3Z-FL-GBW-V3.

To start off can you please post a screen capture of your terminal log.

Finally have you received your second display? If so can you please confirm the operation status.

Thanks!

Very exciting!

Be sure to keep us posted on your progress  ;)

Hello Michael!

I highly recommend you check out CadSoft's community library repository. This is where Eagle users can upload files to share with other EAGLE users.

Hi Parsec!

I highly recommend you check out this link  ;)

http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone/blog/2014/01/04/bbb--small-oled-graphic-display


Please note the following write up uses the SEPS525 controller (same as our 1.69" Color OLED: NHD-1.69-160128UGC3). You will need to modify the initialization sequence and other various parameters if you would like to use NHD-1.5-128128UGC3.

Hope this helps!
