Hello everyone,
We're currently in the process of porting our code from the NRF51 to the NRF52 (both without any softdevices). Everything compiles and seems to be working...
Hi all,
I am making a device which involves using nfr52832(PCA10040) to communicate with a NAND flash through spi to store data acquired from the ADC. After all the data...
After performing the first ADC operation (4 channel scan, sample rate controlled from TIMER1), the power consumption stays at almost 4 mA for the nRF52832.
Why?
