hi
i'm new to the nRF platform and realised it uses zephyr. i come from a pic & stm32 background with little rtos knowledge and find the official zephyr cryptic. especially the bits i'm struggling on is the device drivers and peripheral API.
for example in blinky sample, i notice that the examples use macros to init the GPIO pin which is not documented in the docs: devicetree guide > Devicetree access from C/C++
i did find the getting started guide here in Nordic guides... but i found it rather thin and backlinks often to the (cryptic) officlal zephyr docs.
i've been hacking into learning zephyr for weeks but couldnt even get a simple push button example... is there a detailed guide/book on zephyr that'll ease the process??
