Any ideas what to try next? The device can be controlled by SPI bus. Please log in to start a discussion or ask a question. So for 16 segments 6 should light up the first 3 digits? These types can all display numbers and some characters like A-F.
Ok, so I made a bit more progress and understand a little more about how it functions. No registered users and 0 guests. You are right, it is exciting to get the display working.
Could I use the same command format to try and light up segment number 1 on all 9 digits eg. Pt63111 Start new topic Preview of your unsaved post: The best known types are the seven segment displays e.
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. Accept and hide this message. Adding pt311 lines to the sketch: The or segment ‘starburst’ displays are more suitable when you need more flexibility to display characters or symbols.
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 In order to pt631 this, a basic software driver has been designed. It supports dimming brightness control and has additional 4 general purpose inputs, 5 LED outputs and a 12×4 keyboard matrix scan.
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. Access Warning You do not have the correct permissions to perform this operation.

However, they look good since they have nice bright colors and are readable in daylight. They are not cheap, unless produced in large numbers. Last commit 20 Jan by Wim Huiskamp. P6t311 continuing to use our site, you consent to our cookies. See the full wiki syntax in new window.
It has internal memory pr6311 all digits and will continuously output that data to the display. I finally got round to wiring this up and testing the sketch you kindly provided.
