Hi all, During my TFT upgrade I missed the conversion of a character on the R6581T display.......but no VFD or OLED to find out what it is supposed to be! I am thinking it's a right arrow? Per attached, can anyone with an VFD/OLED confirm?.........a photo would be great so I can analyze the pixel data. It's on the RECALL, MANUAL display. I was testing a PCMCIA memory card with the R6581T where I came upon it. Ian. |

If I found it right, manual shows ~ (Searched 'recall', around 6 - 16, page 144) I see you have a few lines in character map filled with zeros, for [ ] { } and ~. Line for | (vertical line) also look strange - must be almost like !, but looks like >. |

Thanks guys…….I kinda thought it was a character I hadn’t come across anywhere else in the menu system. UPDATE: Fixed and GIT is updated. UPDATE2: Upper case J symbol fixed. Also add code to send unmatched chars to Live Watch so they can be easily read and converted. UPDATE3: % symbol fixed. UPDATE4: Re-write AUX display including provision of OHM symbols up to 4off 5off per line. Ian. |
