Evaluation Tools / Re: NHD-7.0CTP-CAPE - BBB does not start up properly
« Last post by newto on February 27, 2018, 11:47:01 AM »
Hello Hendrik and/or Paul_B

Lucky timing that this question popped up recently, as I have a related one.

Do the wireless functions (wifi and bluetooth) still work with the 24-bit cape installed (and the modifications listed complete)? I've seen a few places that some of the extra pins required for 24 bit over 16 bit colour are also used for wireless addons for earlier beaglebone boards, and I wanted to make sure those features still work with the integrated wireless chip.

The Multi-font IC can be left open and unused by floating pins 19,20,21 and 22.  The display itself will run independent from the onboard Multi-font IC.

The NHD-C12864WO-B1TFH#-M display can be powered safely by 3.3v so a single power source can be used for your application.

the datasheet says it can be powered between 2.7V and 3.3V:

The microcontroller is powered from 3.3V, I would like to use a single power source for both.

Since I want to use it in an always-on application, I would like to know if there are potential issues (or something I should be aware of) using 3.3V power, or if 3.0V is recommended and I'll have to use a voltage translator.

Hi there ,
We have recently purchased NHD-3.12-25664UMB3 OLED and are trying to interface it with Nvidia TX2 in SPI mode. So we need confirmation regarding the connection of Pin Number 19,20,21,22 {multi-font IC's } is it mandatory to use those pins ?  OR they can be neglected like NC { No connection} OR can we connect those pins to ground ? . Because as of now we are not using Multi-font feature  . Please confirm it at the earliest .

Thanks & Regards

Hi Semed,

Try using the 2 Pixels/byte setting in LCD Assistant.

Please refer to section 8.3.1 on page 22 of the SSD1322 specification for more details on using Gray Scale Mode:

I would suggest an update to the drawing to make the pin arrangement clear to future users. I ran into the same issue and was glad to find the answer here, but it would have been better to have the drawing clear.

The display is mounted with its connector on the upper side. So like in the position in the datasheet. ( Is this correct? I hope so...   ::)

I tried the configuration data 0b10010000 for the A0 register, and this config resulted as in the attached image ( It seems like the character is in the correct form and drawn from the correct corner, but streched and misaligned.

What should I try?

Thank you for the information, can you please let me know how the NHD-1.27-12896UGC3 module is mounted in the enclosure? Any chance that it is mounted upside down  :o

Sorry, I have to check for my own sanity...
