uart +switch +lcd coding

Is there a question in there somewhere? Also please read the posting tips before pasting in source code in an unreadable form. Thanks

That was an even bigger fail than the first post. I guess reading the posting instructions and looking at the preview taxed your concentration too much.

I answered the post! Look. I added some relevance to the mess.

I added some relevance to the mess.
a relevant mess is still a mess

the issue here is the OPs imnability to read/follow directions

the issue here is the OPs imnability to read/follow directions

Whooooooshhhh. The sound made when something said passes straight over your head.

well, that is obvious, you did not not the instructions either

@kevin matusch ....u r a no match dude (being sarcastic) #sic.

define:"erik malund"

Verb, example "to erik malund a post". Entering text into a forum and hitting the post button without first checking for typographical errors, grammar, spelling etc.

that may be, but I follow the posting instructions
