Hi all I'm trying to build a generator based on NRF52832. Outpit signals are: 8MHz clock and two latches signals highly sinchronized with clock - RGB_LAT and TXT_LAT. For this task I used TIMER1, PPI and GPIOTE. Actually my approach is working as expected…

Hi all: To saving power I implement the function to read data after interrupt is triggered.. below are my codes.. My expectation is.. Let CPU enter idle mode to wait interrupt by call _WFI() After interrupt is triggered start to read data and…

According to the product specification of the nRF51422 the current between the advertisements is: i_sleep = I_on + I_rtc + I_x32k 16k Ram enabled: = 2,6 µA + 0,1 µA + 0,25 µA = 3,1 µA 32k Ram enabled: = 3,8 µA + 0,1 µA + 0,25 µA = 4,3 µA for…

I have an application (with SD S212) that uses NFC. Ideally, the processor would be in idle most of the time, waking up only to FIELDDETECTED and FIELDLOST events. The processor starts off sleeping fine (consuming the proper amount of current, about…

I am using nRF51422 with a 16MHz crsytal, HMC5893, LED and MPU6500. I have noticed that the power consumption in IDLE mode is approx 1.2mA. This was originally at 6mA. I call the function sd_power_system_off() within my main program. This reduced the…
