Are you making a product out of this VFD->OLED conversion, is that your goal? I have lots of ideas but maybe another thread is a better place to discuss and get the community to collaborate. But I understand if you want to do this on your own. While open source is a wonderful notion, I don't think it's at all realistic. |

I'm not an EE, i'm just a software engineer tinkering with hardware on his own time. I don't plan to make a commercial product out of it, I don't think it would viable for production anyway because of too limited target audience. And the money I would make off it would be peanuts compared to what I'm paid to write software for the big leagues (wink, wink ;) ). I will just open source everything when it's ready. Progress pic of the day, made new display work: Starting on secret feature now :) |

So cool. I see you've got annunciators (at least one in the pic) and the sampling indicator, too. :clap: Oh, the suspense... |

Hi, nice to see that someone else has done this with same parts that I planned. I have E3634A with broken VFD. I reversed the protocol with sigrok earlier during the winter and ordered 3,2" OLED and stm32f103. But then I got some other things to do and this project is not proceeding... If I recall correctly, some settings and dimming some digits is done inside the cpu in front panel and those are not visible in SPI communication. So it seems that I would need to spy signals between front panel cpu and display driver to get full functionality of the original display. Wictor |
