My display is 9 grids 16 segments actual segments on each grid range from 8 to 16 so initially I tried the sketch set to 12d16s – this lit up a few segments on each of the 9 digits but not all segments on any digits I then tried it set to 9d19s which lit up different segments this time including all segments on 3 of p6t311 digits and some random ones on all other digits.
I finally got round to wiring this up and testing the sketch you kindly provided.

Any ideas what to try next? If everything is right you should see on your display numbers in the following order: The best known types are the seven segment displays e.
The or segment ‘starburst’ displays are more suitable when you need more flexibility to display characters or symbols. The general Notebook page for VFD devices of this family is here. Close Start new topic Preview of your unsaved post: It supports dimming brightness control and has additional 4 general purpose inputs, 5 LED outputs and a 12×4 keyboard matrix scan. This library interfaces to a PT VFD controller that supports multiple display modes from 8 digits of 20 segments to 16 digits of 12 segments segm.
Ok, so I made a bit more progress and understand pt631 little more about how it functions. Last commit 20 Jan by Wim Huiskamp. Access Warning You do not have the correct permissions to perform this operation.

I have a photo of the display which I will annotate this evening so it is clear for you, then upload here or email to you. However, they look good since they have nice bright colors and are readable in daylight.
A lot of the special symbols are controlled by 0x80 so some mechanism for turning this bit on or off will need to be added after the required character is selected from the character set – I’m probably getting ahead of things here though.
You are right, it is exciting to get the display working. A simple sketch is included.
Pt311 do not have the correct permissions to perform this operation. In order to do this, a basic software driver has been designed. A lot of the special symbols are controlled by 0x80 so some mechanism for turning this bit on or off will need to be added after the required character is selected from the character set.
These types can all display numbers and some characters like A-F.

I tried to hide complexities of the hardware implementation so that from application point of view segment mappings are the same for all digits and all digits are linearly addressed by a column number in range Adding these lines to the sketch: They are not cheap, unless produced in large numbers.
