Re: Box function and writing ascii with dec

Hi Casey, Not sure if you had a chance to read the above post yet, however it does include an error, anywhere you see this expression decimal += (1 << (i + 1)); it should actually be decimal += (1 << i ); My apologies. And of course I'm presuming that the switches are indexed from 0 to 7, with 0 bei...

Re: Box function and writing ascii with dec

Hi Casey There are a few things that stand out, though I've not yet read anything to do with the output. You've defined some of your switches as analog pins, which is fine. These pins are general purpose and can be used for digital IO also. In your case however you're using analogRead() in loop and ...

Re: Box function and writing ascii with dec

Hi Casey

Sounds interesting - can you share your code so we can see exactly what you have so far?

I might get a chance to try it on the weekend but it's possible something will stand out when you show us the code.

Cheers!
Geoff

Re: DMDCON doesn't work

Sorry I misunderstood. I thought you already had worked out how to connect your panel up. I do not know if you'll find the answer to that question here for a non-Freetronic DMD panel. Some of those markings appear similar so you may be in luck but it will require a lot of testing on your part.

Re: DMDCON doesn't work

Exactly. You do not need to use DMDCON to use Freetronics libraries so long as your DMD panel works with the Freetronics libraries when connected correctly with hookup wires. I don't. In your case you'll need to create something that has the same electrical connections as the wires if you want to us...

Re: DMDCON doesn't work

Unless I'm misunderstanding what you're asking I think modifying the DMDCON is not possible but creating your own derived from the DMDCON design is. If you like the design of the DMDCON but you know the connections between your DMD and the Arduino, the DMDCON is open source so you can modify the des...

Re: DMDCON doesn't work

It looks like you could tidy up your cable problem by creating your own DMDCON with the connections the way your "DMD" needs them. It's not that difficult to do - for most of my projects rather than trapping an Arduino in the final version I've constructed a ribbon connector on a custom board. In my...

Re: creating urdu font for dmd

Hi, If there are 48 symbols in the written alphabet (I'm basing this on wikipedia), you could substitute those in a customised font file for A-Z and a-v and still maintain numerics, mathematical symbols etc in the ASCII set. There's quite a bit of information on creating a font file that works on th...

Re: DMD split row into column

Hi, Yes this is possible. In the DMD2 library example for the marquee you can see the text box that the marquee is displayed in is defined as a full DMD in size. DMD_TextBox box(dmd, 0, 0, 32, 16); It doesn't need to be though. In your case it would look something like DMD_TextBox box(dmd, 33, 0, 64...
