Hello :)
For the code below, why are we defining the _wfi while in the code we only use _WFI() for addressing the function? Also once we use _asm volatile ("wfi); isnt the...
Hi:
my sdk is about 96k,and i use 51822QFAC,but it's flash is 256K,(256K-88K)/2=84K,so it is not enough for me,how should i do,if i add a external flash is ok or do you...
Plz help me with code or sequence of steps being followed by _WFE() or power_manage() functions. by which they manage the nrf51422 to run in low power mode.
So that i can...
