Hi rushin

Would this button press solution be useful to you, or do you want to use app_button directly?

By the way, what nRF51 SDK version are you using?

All that a button does is to change the voltage level on a GPIO pin to generate an interrupt. If an external circuit also changes the voltage level in the same way as a button does, you can use the same button code to detect an interrupt from an external circuit, as e.g. the adxl345.

Update 8.1.2016 To use app_button, you need to initialize app_timer and app_gpiote, because app_button uses those libraries internally. A good app_button code example is available on Github. The example is for nRF51 SDK 8.0.0 but it should also work for nRF51 SDK 10.0.0
