Hello !! Thanx everyone to solve my previous query so quickly.. :)

i am facing a simple problem that i have made my sub modules of voltage measurment, voltage averager, probe logic and frequency measurment individually and everything is working fine !! But when i combine them all in main module using switch case, the frequency measurment part doesn't work.. any idea why it is creating such problems ?? i have attached my code along with my post..

Where is the declaration of your interrupt procedure for the timer? I miss a CY_ISR or a CY_ISR_PROTO?

I usually would write

Check your comments for correctness.

Check your comments for nessicity: "LCD_Position(0,0);//Position cursor on LCD"  here the comment is obsolete

Check your Indentation

Happy coding

Bob

yup.. i think it is the problem i am facing.. but where should i initialize the timer interrupt routine ?? the code is going upto printing the frequency statement on lcd.. but i think it is not going further.. any help ??

Initialize the interrupt and the Timer-Module once, then (if you prefer) you can disable them with the appropiate API-Call.

In the corresponding procedure you can enable/restart them and(again if you prefer) disable them.

The right place would be the function (I hope you already took it out of the switch-block) where you measure frequency.

I (normally) put an isolated function like measuring the frequency into a complete different .c-file and make a .h interface. Later when programming a completely different project I have the opportunity to re-use that piece of software.

as per suggetion i used counter initialization and isr initialization outside the switch case.. but still no success.. :(

i am doing it wrong ?? can you please modify my original code so that i will fully understand my mistake and will try to avoid them in future..
