how to create modes?

bobsmith

How do i create modes so i can have like 4 different modes that my pushbuttons can select to use by using the toggle command?

Jon Williams

TOGGLE flips the state of an output pin -- not what you're looking for.

You can create a mode variable in your program, then update it with a button input. I'm a bit fan of using the modulus operator in these cases. If you have four modes, it would be sensible to keep the value in the 0 - 3 range. You can do that with the mod opeator:

IF (NextBtn = 1) THEN mode = mode + 1 // 4
IF (PrevBtn = 1) THEN mode = mode + 3 // 4

The first line will go 0, 1, 2, 3, 0, 1 .... and so on. The second line will go 3, 2, 1, 0, 3, 2 .... and so on.

how will I be able to select the modes in this code below through a push button with the way you are saying.

You're mixing BS1 and BS2 code statements. Which micro are you running on? You've also got severl incomplete statements....

i know alot of them are incorrect and incomplete. This is the first time I ever programmed. I will be using a bs2

Jon Williams

Let me suggest, then, that you work through our "What's A Microcontroller?" book -- you can download it free and it will the few hours you spend with it will be well rewarded in time and frustration saved. StampWorks is also helpful and has lots of BS2 samples that you can plug into your application.
