so requirement here is if you know how to use the internal RTC and also add 3 pin interrupt that work all the time that satisfies my requirement. 2- I need some help with sending nrf51x into low power mode that is just sensitive to external interrupts and also bluetooth received packets interrupts.

Looking for a person to finish a design a 4-axis stepper controller with Raspberry PI 3. This is used to control a large stepper with typical current >1A per axis. A separate drive (commercially purchased or designed one) for stepper can be used. The function for stepper will be bi-directional continuous move at selected speed, bi-directional fixed step movement as fine as 1 step/microstep. A blue tooth based remote controller (continuous job, step, speed selection, buttons) also need to be designed in such way that it will be able to be power up with 2 AA battery for 6+ month with occasional use per day. The current selection is oriental motor's open frame drive board. So the RPI3 will only need to generate pulse train. But the final selection of the motor and drive will be determined with contractor and mechanical requirement. The deliverable: specification all purchased parts and its vendor all design for any designed parts any code used help constructing a prototyping wiring instruction remote controller design and code power consumption estimate on remote controller range estimate on remote controller
