Posted: 02 January 2009, 20:26 PM Post subject: hierarchical menu interface code |
|
|
Hello
Does any have or use a hierarchical menu system to use in ZBasic for displaying on an LCD. I have used Tinymenu and just found Micro Menu, both in c... which I am looking at interfacing with the zx24n.
Just want to make sure Iḿ not doing things in a round about way.
Thanks
Neil

I have one I have been working on for one of my projects that uses a 4-line serial LCD and four pushbuttons.
I make no claim to programming greatness but I will send you a copy of what I have created if you are interested.

Here is a copy of my dual electrical generator controller project. It is about 50% complete. It has a menu system in it that I have been working to make modular and semi-universal. It uses a 4-line serial LCD and four pushbuttons.
Any and all help and suggestions welcome!

Thanks Christopher
Its an education for me to see how other people do things, I may have some more questions/comments once I understand things 
Id written a simular DS1305 module also... but Iḿ sure I can improve it... havnt tested it yet.

Only my comments as I look through understanding things... really making the comments to learn more myself... so opolgies if Im wrong or say stupid things  dont mean to pick on code etc...
I had not realized that you can define functions/sub and leave off the byval or byref... and was supprised that the default if not specified was byref...
1) Just was confused, as it didnt seem that you modified some of the function paramters which were defined by default as byref ?
Ive attached the c code for the micromenu code, not my own, in case its usefull at all... Im still looking and working things out from your code

This is clearly stated in the ZBasic Reference Manual section describing Subroutine definition: | ZBasic Reference Manual wrote: | | The default passing convention, if neither ByVal nor ByRef is specified, is ByRef. |
I suspect that some prefer to omit the ByRef/ByVal just to reduce typing. It is unfortunate, I think, that the default defined by VB6 is ByRef. It would be better if the default were ByVal in my opinion.

I didnt mean to say that its not clearly documented anywhere... sorry if it read like that... Id simply skipped over, or not seen that part when I was reading the manual... which is well and clearly written. Not meant as a criticism at all, but my own mistake.
Yes my thoughts as well that default would be better byVal, but Im pleased I noticed it finally in the clearly written docs.
