ProTip for Embedded SoC Development - static IP set by router

These days of developing with multiple SoC (Raspberry Pis etc) it has become a great idea to set a static via the router based on MAC addresses.

Basically you ask your router to always set the same IP address whenever it sees that network hardware connect (either a NIC or a wifi adaptor).

This is very different to setting a static IP in the device's operating system itself.

When you rely on SSH'ing from a separate PC into the device, knowing which device will have which IP regardless of the fact you just switched SD card and hence operating system is a real time saver.

The exact process of how to achieve router MAC based IP allocation differs for each router but usually is an available setting.

Raspberry Pi 5 inch Touch screen with HDMI

January 2016

The Raspberry Pi 2 is a capable PC and therefore is worth putting a screen on it for some applications.

I bought a 5 inch screen with touchscreen from eBay. It was titled "5-inch Resistive Touch Screen LCD Display HDMI for Raspberry Pi XPT2046".

It cost ~USD$40 (January 2016)

It has a resolution of 800x480.
