--- Quote from: branadic on December 17, 2024, 05:33:23 pm ---Thanks, a VFD like look instead of the Rigol color scheme would have been nice, but I also like the look of the Valhalla 2720 display. -branadic- --- End quote --- I used the built in font on the LT7680A-R so very much restricted to that. However, unless I am wrong I think there is an option to load complete fonts to the flash IC on the pcb but I never looked at doing that at all. Ian |

I thought that you did created a new font for this IC. However if I remember correctly (because I was looking at this board when ordered this display) the biggest limitation is the font size that it can hold, so you won't be able to draw big digits. |

When I wrote "VFD like look" I meant color-wise, so more green/blue'ish instead of the Rigol color scheme with yellow, cyan and green. -branadic- |

I am using a 16x32 font and scaling that up which works out just right for the MAIN display I only created a new character for the OHM symbol. Ian |

Due to the smoked window some colours don’t project enough even with the backlighting at full brightness, hence yellow/white seem best at least for the main row……in my eyes anyway. I’ll try and come up with a way to select further colours…….i guess ultimately the user could pick their own and save. Ian. |
