Hi, I have tried to add support for BOS descriptor by appending a custom class generated from the Dummy example. The "main" class is the HID generic class, but with the NRF...
Hello
I only used PWM_library, but this is my first time using PWM_driver. Simply controlling the duty cycle of multiple channels has been successful, but I am not sure...
A little backgroud for my project. The goal of the project is to be able to identify the proximity of beaconing devices in an area to a specific observer which then reports...
Hi, Below is the mapping of RAM on the 840 from the infocenter. We want to utilize the functionality to turn off unused RAM (via sd_power_ram_power_clr), but we see that if...
