Hi Everyone,

I will working to implement the Counter with Development board OM13098LPCxpresso54628 (eg. I give some Plus in Counter pin that is read the count value with Every one seconds).

How to Configure and implement the Counter registers and What are the step to follow?
Any Counter Sample program is available?

Thanks & Regard

Vijay

Hello @Vijay_Vj

You can consider below steps:

1） Define a global variable cn.

2) Enable plus pin interrupt, in the interrupt, cn+1;

3)Configure timer, read the value of "cn" in each seconds interrupt.

Just a simple suggestion.

And what are registers to Configure to Counter?

Hello @Vijay_Vj

1)There are some basic demos about timer, counter under SDK, for example "ctimer_match_example".

Download SDK from:

https://mcuxpresso.nxp.com/en/select

2) Also you can use MCUXpresso configure tool to config refer to your requirements:

Hello @Vijay_Vj

Sorry there isn't an example code exactly for your application.

Recommend you refer to user manual of chip and SDK demo to development.
