However, they look good since they have nice bright colors and are readable in daylight. Close Start new topic Preview of your unsaved post: If so do you specify 9 in case we are using more than 16 segments?

So for 16 segments 6 should light up the first 3 digits? You are ;t6311, it is exciting to get the display working. The best known types are the seven segment displays e.

Ok, so I made a bit more progress and understand a little more about how it functions. It has internal memory for all digits and will continuously output that data to the display. The general Notebook page for VFD devices of this family is here. I’m sure this is not the most efficient way to do it but at least I’m making progress.

Any p6311 what to try next? 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 p6t311 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. They are not cheap, unless produced in large numbers.

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 pt631 character is selected from the character set. You do not have the correct permissions to perform this operation. The device can be controlled by SPI bus.

Access Warning You do not have the correct permissions to perform this operation. Adding these lines to the sketch: 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 pt3611 linearly addressed by a column number in range Could I use the same command format to try and light up segment number 1 on all 9 digits eg.

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 the digits and some random ones on all other digits.
