Nextion screens make HMI development simpler

800px-Nextion makes nice little TFT screens (up to 7″) that make the HMI (Human Machine Interface) a lot simpler. Instead of having to program a TFT screen just about for each pixel, this lets you design the screen separately and interface through rs232 ttl levels. So far I have tested these screens with ESP8266 and Arduino. But since the protocol is quite simpel any ttl level rs232 device should work.
