Hello,
I want to save some structs to flash using pstorage with S130. What would be the best way to achieve this?
The struct consists of message, deviceID.
The whole...
I am designing a NRF52 based device. Do I need to add ESD protection circuits on PCB for any pins on NRF52? The initial device I am making is for prototyping a system. so...
Using nrf_delay_ms() can be energy consuming and indeterministic. I am trying to use application timers (from "app_timer.h") in nRF SDK 8.0. The way I did could be partially...
In a previous excellent answer Ole Morten explained how to calculate the maximum throughput of transmissions using notifications . I'd like to know what the calculations are...
Hi,
I am a newbie. I understand that a similar question was asked earlier, but I couldn't get an answer specific to my questions. My goal is to sample an analog signal at...
