Hey,

I always used this to make a motor spin with a button.



But now I have to make it so I press the button once than it goes spinning at 50% and if I press the button again it stops.
i hope anybody can help.

It works tnx a lot
but now we have a problem because of this code the rest of the program stops working
and i cant use a while(1) command cuz that is activating the robot on command so we cant use it without a different programm telling it to run.
so i tried to remove the while true command and than the command doesnt work

i am a noob programmer :}

It won't work because you need to adapt it into a seperate task....

No, you don't need a separate task. You just need to put your other stuff inside the same while loop.

right but when we do that, everything will get delayed by 100ms...Probably not a lot though

It is recommended to do some delay between each loop but it doesn't have to be 100 msec. The delay will help with the button debounce. If your other stuff needs to be processed more often then the minimum debounce time, you could process the button once every n loops. Then you can do a 10 msec delay or less in each loop.

we got around this problem but using a timer to check whether it has been 200ms since the last check. Then if so, you reset the timer and do the cycle again.

Sorry if this is old; but wouldn't it work if you use:



What would be the advantages/disadvantages of either?

Ah! that's actually a nice way of doing it...

I sometimes find that simple is better.

What's a toggle?

A toggle is like a button that when you press it, it alternatingly switches something on or off.
