I want to make controller version and pga2310 atmega8515. We all components but I need some help with a VFD display!
It's CU20029ECPB-U1J. 2x20 character VFD.
This display has 4 levels of brightness, but do not know how I can change these levels.
Here is the datasheet of display : http://www.meditronik.com.pl/doc/a0-a9999/vfd20x2h.pdf
Can someone help me?

Hi rob86,
Looks like you can use bascom command LCDCONTRAST

LCDCONTRAST x ' X = 0 to 3

from datasheet SOFTWARE COMMANDS - you have "Brightness Set 0 - 3"

This is quite a long thread! is there a group buy for any of these projects that is still active? What is the best method for volume attenuation? Is it stepped resistors or using a chip? I'd like a good volume control for my Phase Linear 400 Amplifier.

Hello Wanted: Digital control with a chip on the controller PGA2310, with output to LCD display. In this forum, I've seen similar. Could you please help me to give firmware scheme and seals in one file, I'm pretty hard to read the whole forum because I do not know much English. I live in Kazakhstan. If it is possible for soap xaker.66666@mail.ru. Thanks in advance.

My project is finished now and partially working. Not tested yet the remote control part but so far the most annoying thing is that the LCD backlight is not working. When i'm shorting E and C of transistor that is responsible with backlight i have light. Also on the pic 17 of uC wich is triggering the transistor i'm not measuring any change with DMM. I have tried all software and same result, not backlight. Any ideas ?
