Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : FONT 4 characters 220, 221 and 223 are borked

As found by new user @RAM26 here:

Peter/Geoff here are some corrections for file "Fnt_10x16.h":

Tom and Jim,

Thanks very much for the great responses to my request.

Tom, you hit the nail on the head when you mentioned all 3 characters were not right.

Jim, thanks for providing a solution that's so easy to implement.

Now, I wonder - can I make this change to the font permanent?  If so, how?

Jim, where can I find the FontTweak utility?  Is it still available?

Also, with MMEdit, is there a way to map that into the system editor F4-F2 cycle?

Please advise on all.  Thank you.

I expect that the changes to the font will be incorporated in the next MMBasic update.

FontTweak.zip
I will include it in the MMEdit ZIP one day.

I have never tried to integrate MMEdit with the inbuilt editor and not likely to do so.

Sending a 'list' on your device to MMEdit is simple and sending MMEdit code to the device is just as easy.

Thanks again Jim.  You rule.

My goal is to hack Font #3 (16x24) to display the upper 96 characters of the old IBM ASCII codes.  I think these tools will help get me there.

Unless...maybe you've done it already?
