Quite a while ago now I did a project based on the little Nextion displays, resistive touch-LCD displays which run on serial commands and come with an editor to make simply touch displays for even the simplest of micros. Well, that project has proven to capture a lot of interest…

Nextion Update
As you may know the home control software can work with Nextion displays and there is a project on the blog on that subject – I note that one or two people are having issues here so rather than reply without pictures – here’s a general update. Currently with the…
New PCB
After a slight hiccup with the new board (LED track missing) here’s the new board – link for PCB here – as you can see, Aidan has made several improvements – smaller buttons, connector for DHT22 etc, markings for I2c (right now I only have support for the 8-output expander…
esp8266 Annual Awards
Just a note to say THANK YOU to everyone who voted for the Nextion Wifi Touch Display over at esp8266.com in their first annual competition. I just found out this morning that we won second prize, beaten to the top only by the excellent esp8266 Basic Interpreter – a great…
Nextion WIFI Touch Display
This award-winning project ** is a development of previous (home control 2016) work on the Nextion touch serial displays and offers a WIFI-controlled (MQTT) touch display which can be used with the full range of Nextion displays from the little 320*240 display you see here, up to the 7” model. …
Wifi Nextion
Regular readers will remember me ranting about a little board we were making to fit on the back of a Nextion to make it wireless. Well yesterday was a very productive day – the boards came back from China. Somehow they’d managed to disconnect the top floor layer from earth…
UI Update
I’ve been busily beavering away at a commercial project for the last couple of weeks but that ends at the weekend and I hope to soon have some more reviews of new and interesting products for you including some surprisingly cheap SBCs. Meanwhile, close to the heart of many of…
The Nextion Experiment
Our latest experiment! The board you see to the right should be with us in a couple of weeks. This little number will sit on the back of a Nextion board, from the smallest to the largest without adding any height (hopefully) and contains as you see an ESP-12 and…
Enter the Nextion 7” Display
In previous blog items I’ve mentioned the Nextion displays. These are a fairly unique product in that they offer a simple to use LCD touch display which works serially – and hence are not tied to any device – and they don’t need drivers. I have a very nice “proper”…
Nextion and ESP8266
Ever since I fell in love with the little Nextion displays I’ve been thinking about a little ESP8266 board to go with them – well, I’ve been beaten to it. Today I received in the post a little box from Guy Molinari with his efforts – I have to say…
Some thoughts on Node Red variables
In learning how to use Node-Red I’ve changed my coding countless times as I’ve found better ways to do things. Please note that in 2017, the way I use global variables here is out of date. It still works but for example context.global.fred=1 is now written as global.set(“fred”,1). Read this…
Nextion Talking Thermostat
Yes, I changed the title. As often happens with these things, I got carried away. The Nextion display is a touch-sensitive intelligent display. Essentially, you buy the display and you program it with a free editor serially – which lets you easily place icons, buttons, images, text, gauges and more…
Raspberry Pi Serial and Node-Red issues
SOLVED: Node-Red serial I/O Looks simple doesn’t it – tie RX and TX together on your Raspberry Pi and press the button – text comes out of the other end – except that it doesn’t. More likely the Pi will CRASH (not something you see every day). Serial out seems…
Nextion Displays and the ESP8266
So a parcel arrived for me this morning in the post. A Nextion display. And what is that, you may well ask? Think of something like a thermostat or really any home control situation, at some point you have to stop sending text commands from an expensive PC and reduce…
