Character LCDs / Re: NHD-0216K1Z-NSW-BBW6L contrast problem
« Last post by bidbid21 on January 03, 2018, 07:44:07 AM »
After many search, I think that the problem is caused by electrostatic discharge.
It is possible that connect iron display frame to the ground?
Evaluation Tools / NHD-FT81x-SHIELD
« Last post by CarlW on January 02, 2018, 10:40:46 AM »
Was able to get the NHD-FT81x-SHIELD plugged into a NHD-7.0-800480FT-CSXV-CTP  :)

Downloaded the github zip folder. Renamed the folder as directed.

Although the github download didn't work for me like a typical arduino library, I was able to run the 7" example sketches successfully, by manually locating the "ino" file

Is the github software supposed to be a typical arduino library and I did something wrong?

Is there a way to use the EVE screen editor to output arduino code? After I change the chip to FT813, the export option wasn't working for me.
Again, I might be doing something wrong.


OLEDs / Re: OLED Multi-Font IC Problems

Displays built-in IC controllers have limited functionalities comparing their own original version because they have some of their original pins wired to a certain configuration. You can guess such configuration by comparing the original controller pin-out and the display pin-out.
Understanding the IC controller built-in configuration is the first step before coding the display initialization.
You can find the display specs at and the original IC specs at .

Anyway it's always good fun playing with displays.

Good luck!

Hello Darshana,

Fonts and other graphics are controlled by the software and the controller that write to the display.
The onboard display controller will only show what is loaded onto the RAM.

Could you show me what you are displaying currently for the letters?

There isn't a way to control the brightness for these displays. They are set depending on the voltage input.

Can you let me know the modifications you did to turn the display into serial, also would it be possible to provide a picture of the back of the display?

Im working on Newhavens 2.4 inch display (ST7789S controller, 240X320) certain letters on creating font appears to be stepped ( for example W) this letter does not appear to be smooth, similar is the case with other slanting letters, is it the limitation of the hardware that creates this look for the font. Please do reply for the same.

1. Question 1:
     After reading the NHD-0220DZW-AB5 datasheet, I did not find a way to control the screen brightness. I do not know if the product does not support it or if it is not my way.
2. Question two:
     I have 3 NHD-0220DZW-AB5 displays, but one of them does not work (screen does not light), +5 V power supply, SPI control.

Thank you in advance for assistance.

Hello Chris,

I'm sorry we do not have any example codes in MicroC or xc8.
Many of the i2c examples do use the Wire.h library, however we do have an example where we are bit banging the data to make it easier to follow.

Would you be able to email for this, we would be able to provide this to you.

OLEDs / Example MikroC code for NHD-0216AW-IB3 I2C
« Last post by cbrun17 on December 17, 2017, 02:22:27 PM »

After reading datasheets for the NHD-0216AW-IB3 and US2066 controller, I am no closer to getting this display to work. Frankly, I have no experience with Arduino yet all I find are examples written using Arduino code and libraries. I am looking for a simple "Hello World" example in either MikroC (preferable) or xc8.

Thank you in advance for assistance.

Probably should mention what Newhaven product was used. ::)
