the void first(){   } etc are where you would stick the pieces of code.

No doubt someone can write something much better (and so could I with more time and less tiredness).

The newsoftserial could be changed to the softwareserial library with no problems but the newsoftserial library is better...

I was testing it using the top 2 lines of my 40x4 so that is why the positioning is probably off for the second line text...

The code basically does what I explained a few posts up but you will see if you try it.
Look at serial LCD datasheet to find out the positioning values for the 16x2 LCD.

Hi Mowcius Sorry Yes Im still reading this I have been away and haven't had a chance to come back here.

I have been playing with the first code you gave me ( 1 Button) and I have it working fully.

Do you mind having a quick look to see if there are an obvious errors/problems.

Well not that I can see from a very quick look. If it is working then it is probably ok.

If I get time then I will load up your code on my arduino and LCD later to see what it looks like and if I can suggest any changes/improvments.

If you get the time then you might still want to take a look at the scroling menu I wrote to see if it suits you better.

Hi Mowcius,

thanks Im going to load it up tomorrow to see how it works.

thanks

Hi Mowcius,

I loaded your code up & it looks great and seemed to work fine, but after about 10 - 20 key presses it just hangs.

I have the buttons wired 5v to one side if the switch and the Digital pin with a 10K resistor pulling low the other side of the switch.

any ideas????

Thanks

Ben

Yeah I had an issue with that too. I thought it might be just my wiring at the time but it appears not.

I think I may need to stick in a few delays somewhere. I will take another look some time.

Thanks Mowcius Look foward to your reply.

Hi Mowcius,

I think I found the error in your code

Code: [Select]
 if(line > 2){
 line = 2;
 prognumber++;
 [glow]}[/glow]
 if(prognumber > 4){
 prognumber = 5;
 }
[glow]//}[/glow]
 menu();
 }


I moved the } bracket from the commented out section to the other highlighted section and now I doesn't lock up.

I think what was happening is that when you press 2 button simultaneously it would make the line number = 1 and the prognumber >4 so the if statement would allow it to go though..

What do you think

Ben

advancedservers

Sorry Scratch that it still does it :(!!!!

mowcius

Yeah, sorry I have not had time to look at it yet.

I will post it up as a seperate topic and see if anyone else has any ideas...

Cheers for the code!

Trying to make my own adaptation to this, but not going very well so far :(

Hi

Post your code and I'll have a look
