I see what your saying but as the code I posted it works. I think, not sure, but I questioned the same and tried trisc-%11111111 no difference I recall but will run the code again to be sure. Waiting for a new picki2 from China as mine decide to fry itself. Have a pickit3 but the board needs its own...

this game is similar to Mexican Train but faster version. Had trouble inputing then counting the button presses in sub route ttt() this is a rough draft that still needs cleaning up but it appears to work as desired. Any suggestions appreciated. { ****************************************************...

Well here is an Alphabete file with upper / lower case letters. Did it in open office
hope you can use.
As for the brightness of the LED display, iy appearsd very bright. Could be using the 18F24K20 ??

YES thank you.
I just need to correct my schematic incase I decide to make more.
I have the first 4 bits connected to the matrix wrong

It is the same issue as when I thought?? it was / is a memory issue
will try your suggestion

found that the code freezes when using battery power but not when pickit2 connected.????

here is the compressed file. It shouldn't matter that I had to rearrange the const data array bits as I mistakenly had the boards wired wrong (the first 4 bits had to be reversed) but it shouldn't make a difference. going to try the code on my proto-type display to see if it locks up as well. Lookin...

One big issue now is it cycles one time correctly then starts jumbeling text then freezes up.
thinking it is running out of memory with all the const arrays etc.
usiong an 18F24k20 pic

your code really helped.
I changed the ports, eliminated portE and D, redid the const arrays and ran out of memory (too many bytes in the const arrays).
Thanks

been hacking and still can't get any displan much less a code without errors. In the section Draw Data I get errors Data_Bus = Sentence_Data XOR %11111111 ' reverse the data bits I need to get this working as I received my boards etc. { } { ***********************************************************...

enn hacking and added a couple of sub routines so green and red are enabled. There's got to be a way to get rid of all the code repetitiveness but time is getting short and as soon as my boards arrive it's assembly time. here is my code to data customized for my brother. NOTE every time I post a cod...

trying a different approach by trying a code that was supposed to work but?? really need help to get the dang code to display text smoothly if possible You might reconize some bits of code from your projects. ***************************************************************************** * Name : UNTI...

I think I found an issue
the anodes are never used within the code??

yes and yes
The design schematic I posted might not of had the resistors on the anodes on portc
something really going wrong??
am wondering if I inserted a 18f2420 and not the 24K20 maybe the ossc settings or ?? settings but I ??? it.
had other codes I posted that worked.
