libgpiod at LubanCat GPIO Pinout - doc.embedfire.com
doc.embedfire.com › linux › imx6libgpiod. libgpiod is an attempt to bring Arduino-wiring-like simplicity to the LubanCat. The goal is to have a single common platform and set of functions for accessing the LubanCat GPIO across multiple languages. libgpiod is a C library at heart, but it's available to both Ruby and Python users who can "gem install libgpiod" or "pip install libgpiod" respectively.
Piversify — Exploring the 3.3V Power Rail
raspberrypise.tumblr.com › post › 144555785379May 18, 2016 · The Raspberry Pi’s power network consists of three power rails: 5V, 3.3V and 1.8V. Since the model B+ was released in 2014, a switch-based buck converter is used to step down from 5V to the lower voltage levels. My focus in this article will be the operating characteristics of the 3.3V power rail which is not discussed as extensively as the ...
1-WIRE at LubanCat GPIO Pinout
doc.embedfire.com › linux › imx6The LubanCat supports one-wire on any GPIO pin, but the default is GPIO 4. To enable the one-wire interface you need to add the following line to /boot/config.txt, before rebooting your Pi: dtoverlay=w1-gpio or . dtoverlay=w1-gpio,gpiopin=x if you would like to use a custom pin (the default is GPIO 4)
