Install Debian OS on NanoPi S2 eMMC

The NanoPi S2(S2) is designed and developed by FriendlyElec for professionals, enterprise users, makers, and hobbyists. It is a small board with WiFi, Bluetooth, and eMMC. It uses the Samsung Quad Core Cortex-A9 S5P4418 SoC with dynamic frequency scaling up to 1.4GHz. It has 1G DDR3 RAM, 802.11 b/g/n WiFi & Bluetooth 4.0 module. Its inbuilt power management unit uses the AXP228 chip which supports software shutdown. It takes power over the MicroUSB port. It has video input/output interface, 3.5mm audio jack, USB port, and MicroSD card slot, serial debug port and ADC pin-header. An Android and a Debian images are ready for this awesome SBC. The Android OS supports HDMI and LCD output.
Along with it has various interfaces, ports such as LVDS, and GPIOs which are compatible with Raspberry Pi’s GPIOs. Its PCB dimension is 40 * 75 mm. The NanoPi S2 works with most of the modules and OS images that are developed for FriendlyElec’s S5P4418 based boards.

Programming Onion Omega 2 using Python | GPIO Access

This tutorial is all about developing python applications on Onion Omega 2. As the onion omega doesn’t come with python pre-installed, we need to install it ourself. We can write a variety of scripts using python for Omega 2 and most importantly for IOT application we can access the GPIO of omega 2 by using python itself. So let’s check out how to do that. And if you are unaware of what is onion Omega 2 you can check the official website for more details and even buy one to work if you don’t have one and for those links are down below. And to check more videos around Onion omega 2 like this there are links for that too.

Omega2, the $5 IoT computer.It is a Linux computer designed specifically for building connected hardware applications. It combines the tiny form factor and power efficiency of the Arduino, with the power and flexibilities of the Raspberry Pi.

NanoPi S2 GPIO Mapping to access using SysFS

May 13th, 2017 No comments

In this post, I have mapped all the pins of Nano Pi S2 so that the GPIO can be easily accessed using SysFS.

This post is all about GPIO pin numbering to use with SysFS. In this post, I have mapped all the pins of Nano Pi S2 so that the GPIO can be easily accessed using SysFS. The pins are mapped according to the following formula,

sysfs pin number- X(GPIOX)+Y(GPIOXY)
Where,
X value depends on the GPIO group and is like below
GPIOA: 0
GPIOE: 128
GPIOALV: 160
GPIOB: 32
GPIOC: 64
GPIOD: 96
and Y is the pin number next to GPIO group name

Information Display System using WeMOS and MAX7219

May 12th, 2017 No comments

This tutorial is all about making a WiFi based information display system using WeMOS

This tutorial is all about making a WiFi based information display system. This system is built around ESP8266 but not the standalone ESP8266 instead WeMOS is used and programmed using Arduino IDE. So In this video, we will check out how to make an information display system like that using Wemos and MAX7219 based dot matrix display modules. The display system fetches data from the local/online server and displays the received. In this system, u can display any data that you want and that’s up to you however over here I am using this to display my YouTube subscribers and twitter followers count.
