After find I found this excellent thread here I decided to build one.

I've added LCD and NRF20L01 to send data wirelessly, Now I know my link is good between the RX&TX as I've tested them separately with a counter and they work. The TX sends out a counting number and this is displayed on the RX unit via an LCD.
Everything works on the TX unit and displays the data correctly on the LCD but if I un-highlight sendDATA it seems to freeze out and the send serial data send it once then freezes, Now I tried it in several places but get the same result as you will see inmy code, Not sure where I'm going wrong or what's causing the problem ?
I think it something to do with the in mpuInterrupt part.
Sorry I've had to add it as a file as I've exceeded the text limit count
