[Solved] Slider widget glitch/lag

6 replies above @Costas - @Dmitriy asked me to pull the code that had anything to do with that slider ie V29 . So I just screenshot it so you can see it. Are you saying though that even though there may be a code issue it wouldn’t affect the IOS slider but it would affect the Android slider ?

Cheers

It’s possible, yes.

Showing the V29 entries in isolation is wholly inadequate.
Do you have calls to Occupied() or Check_Away() anywhere in your sketch?
What data type is SetPoint1?
Do you have any SimpleTimer routines in your sketch?

I have the same problem. iOS had no problem, but on Android the slider doesn’t update in certain lines of code…

Hi @Costas,

Calls to occupied and check-away are done via a timer and setpoint1 is a float vrbl. I don’t understand why taking V29 in isolation is not enough, as surely if the slider jumps to zero then the code must be writing to V29 to do this and if that is the case the IOS slider should jump to zero should it not???
If you want the code in its entirety let me know and I will upload it but there is a lot of superfluous stuff you don’t need to worry about in it and it’s over 300 lines

Yet the tiny extract of code you posted states otherwise!!!

Hi @Costas can you explain? have I cocked up here some where? should it be and int rather than a float ?

reason I use a float is I add .3 of a degree to the value for hysteresis control in the code. Could this be the issue

here is the full code for you to look at - this may be one version behind as I code it in 2 different buildings but should be 99% the same as it is work in progress and not fully finished yet

@newdos one significant bug that you have is that you are trying to send a float to the Slider widget that only accepts an int. The normal response for a Slider when you send it duff info is to reset it as zero.

okay I can try that - is that not the case for IOS slider then ?

iOS and Android cores are written by different people. Maybe iOS coder wrote up “do nothing when user sends duff info”.

OK Cool @Costas hope this is the cause - will test tonight and let you know the outcome.

Thanks for all your help so far guys @Costas, @Dmitriy, @Gunner, @BlynkAndroidDev

It seems that floats are the cause of your issue. I’ll add parsing floats as ints in the next bugfix release.

Yes guys changing it to an INT instead of FLOAT works!!! however there is a screen issue as well as it doesn’t slide very well and likes to jump to zero still when I slide it, but now as the code is writing to the V29 pin it doesn’t go to zero any more. Wonder if any of my english friends have used a Tesco android Hudl tablet which is what I am using for my android development platform - wondering if the screen isn’t brilliant on them

Thanks again guys and keep up the good work!!!
