Evaluation Tools / NHD-FT81x-SHIELD
« 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.



Customer Projects / Pachinko Counter Version 1
« on: December 13, 2017, 07:16:33 PM »
This was a fun project for my hobby - pachinko.

The folks at the Newhaven Forum were helpful; thanks!

I'm excited to start on version 2 with the new shield and larger displays!
Think my pachinko counter shield will fit in between the new products with no modifications but have not tested.

The housings were 3D printed.

This project "keeps score" of a pachinko machines shots and winnings.

The side boxes are optional and are used for game artwork and have a LED ring inside.
The speaker fits on either side end cap.

Evaluation Tools / NHD-4.3CTP-SHIELD-N

Just starting a project with this shield. I'd prefer to use the Arduino MEGA

Can I ask a few beginner questions?

In the User Guide, the shield is shown plugged into an UNO and also shown plugged into a MEGA.
Assuming the MEGA is not a clone, is it safe to assume no solder jumpers need to be altered for my project to utilize the MEGA?

Any thoughts on getting access to pins (on the MEGA) that are not used by the Newhaven Display?
Would a PCB, pin breakout shield, sandwiched in between the Newhaven Display and the Arduino work?

On the MEGA, are these the only MEGA pins utilized by the Newhaven Display: D4, D8, D9, D10, SPI MISO, SPI SCK, SPI MOSI, 5V and GND?

There is a recommendation in the User Guide to use a 7V to 8V power supply, yet the MEGA allowable input is 7-12V?
Reason for the question is 12V power supplies are widely available.

How much current (from the 5V, MEGA regulator) will be available for my project?
I see the Newhaven shield uses about 400 mA MAX.
