| Need help finding info on Futuba VFD display. |

Super close now, it got rid of the random gibberish I was seeing before, however, the character set seems all screwy, as you can see in the last clip in the following video. It's almost usable but now I just need to figure out what's causing this. I'm going to try hooking it up to the other one again, if I don't edit this, assume I had the same result there. https://youtu.be/i1dzDFq3c0I |

It looks like the baud rate is correct. I'd fiddle with the number of data bits, stop bits and parity to see if you can fix the problem with some of the characters being bad. |

Maybe you are sending data too fast? I have seen VFDs needing some time to process commands/data. |

I'll have to just randomly try all the settings for stop bits and parity, since the arduino guides don't mention what they are. I figured it could be something like that but I was not sure. --- Quote from: bktemp on March 18, 2016, 02:40:25 pm ---Maybe you are sending data too fast?

I tried 8N2 as a first go and it seemed really promising, and it is in fact the best out of all the others I tried, but it still has a little bit of a corruption issue, It's so very close, but in the first few characters it gets corrupted, except for sometimes when that is the trailing end, though even then it happens quite a lot. |
