pynextion

A Python library for Nextion smart display management

Source: http://wiki.iteadstudio.com/Nextion_Instruction_Set

Wiring

To use a Nextion intelligent display you need:

• a USB TTL converter (such as those using Prolific PL2303 chip
• or a computer with TTL output such as Rasperry Pi but probably many others single-board computers (SBC) with Universal asynchronous receiver-transmitter (UART).

Please follow the following wiring:

• Red wire 5V
• Black wire GND
• Yellow wire (between Nextion RX and USB TTL TX or SBC TX)
• Blue wire (between Nextion TX and USB TTL RX or SBC RX)

!!! warning

Do it at your own *risk*!

Bad wiring can result in damaging the Nextion display, the USB converter or maybe more.

If you don't know what you are doing, it's maybe safer not to try!

Running
