Stm8s003k3 temperature measurement

[KRiaz.1]

Hi  Everyone,

I am using Stm8s003k3 to measure the temperature of three different places. Then displaying each temperature on 3 digits 7-segment display (3 of them to show each temperature separately). Now to display the temperature on all 3 seven segments I need to put them in the main loop and then the code should be executed without delay otherwise it will Dim the displays. My problem is I need to perform calculations and some other tasks if do those there is a delay and so my display got Dim any solution recommended how do I display temperature on all three displays while performing other tasks as well?

I suppose that you have multiplexed display ( https://en.wikipedia.org/wiki/Multiplexed_display ). Setup timer to generate periodic interrupt (for example 1ms). Handle multiplexing in interrupt service routie. Then you can do anything in main loop without disturbing the display managment.

Hi Michal 
First of all, thank you for the reply. I can do the basic coding right. is there any example or any exemplary code so that i can just lear how to create interrupts?

Yes. But depends on your compiler. For example:
