SAADC Multiple Channel and Timer

Question

I want to enable a timer to start SAADC Multiple Channel and get value of each channel after every 1 seconds. 
 There are many questions on how to enable a timer to start SAADC conversion every period. But never found a simple example.

The SAADC example in the nRF5SDK shows you how to setup sampling by using a timer with PPI. The example samples one channel every 400 ms. 
 You have to: 
 
 Expand the buffer so that if fits the number of enabled channels 
 Increase the timer from 400 ms to 1 second 
 Enable each channel by calling nrf_drv_saadc_channel_init() 
 
 Triggering the SAMPLE task will cause the SAADC to sample each enabled channel.
