There’s a discussion going on in here about the M5 Stack and one of the guys says he wants to use ESP8266 – now then is possibly a good time to announce that I’ve been updating the code in ESP-GO for the ILI9340 and QD-Tech displays. It is all in the doc file but here are some pics… An ESP-12 board plus cheap display..
Above the ILI9340 and below the smaller and lower res QD-Tech display board, both dirt cheap, in the example below, boxed up on the wall as a stat display…. I’ve added the option to re-purpose gpio4 and 5 in ESP-GO for a maximum of 3 auto responders on input state change (trigger2, trigger4 and trigger5) making a thermostat display with buttons a snap.
For the DIY-er on a budget, this is a very inexpensive solution. The display layout of course is not fixed, you can set up your frame, select fonts and update icons as you see fit in Node-Red or other high level environment. The QD_Tech board is lower res than the ILI9340 but I got a bunch of suitable boxes from Ebay for just £3 each some time ago. The light you see is driven by one of those touch sensitive plates we discussed in the blog some time ago. In reality I will end up using 3 tiny buttons.
Peter, a nice little new tft display that fits just on the front of a standard wemos d1 mini 🙂
Good except for the ridiculous price inc post. You can get an ili9341 full touch screen for that. 320*240
yeah, i’ve seen that too late… :/
There’s a nice boxed version, too…

Peter, can’t remember if your firmware supports a syslog server… in case, this could be a valid way to help debug, sending esp-go logs to a temporary log server, without the need of a serial connection or sending logs via mqtt or other ways…

Pete,
Can you suggest a source to get any of these displays from, I can’t seem to find any on Aliexpress or Banggood!
Thanks.
Now you mention it I cant find them so I’ve ordered 3 ili9341 displays with touch. Adding the touch driver should not be a HUGE challenge.
and no need for physical buttons anymore 😀
You need a display as defined here: https://tech.scargill.net/the-wall-display/.
I have tried to order them via aliexpress, but only got ST7735 which is very commonly used and also dirt cheap. I tried this on ESP-GO, but no success. You really need the S6D02 chip based display!
We need a more general library that is also compatible for other similar displays. Peter could you please have a look at it as we are some time further on and see all kind of libraries that are compatible, but also to ESP-GO? Like this? : https://www.ramtex.dk/display-controller-driver/rgb/st7735.htm
I spent far too much time on ST7734 – lots of variations – ultimately got no-where. Don’t really want to waste more time on it, hence ILI9340 code – ESP-GO updated this week to allow 3 button control.
What boxes do you use? Looked for suitable ones for the ILI9340 screens without luck so far.
nice, i should have one of these in my boxes, have to try it 😀
can you share the flow used to populate them?
