ILI9341 seems to work in new firmware

Message

Quart · #1 Post by **Quart** » 05 May 2020, 17:35

I just read that the version mega-20200426 has support for ILI9341 displays
Has anyone tried it and maybe help howto wiring it up to a Vemos d1 mini?

Well, the documentation is quite easy to find using standard Google fu, this page is pretty clear: https://petergodwin.wordpress.com/2016/ ... 266-board/

I just hope you haven't waited (or held your breath) for an answer all these days...

Looking at the release notes:

[ILI9341] Move to custom build due to build size

I think in this case you have to build ESPEasy by your own....

Not 100% sure if there is a 'custom' build included in the nightly build zip, but if there is, it may also be included in there.

Quart · #6 Post by **Quart** » 24 May 2020, 14:14

Cant find it.
Too bad. I looked how I custum build a image but its to complicated for me.
Just have to wait until ILI9341 is included in image or try something else.
I only need a MQTT importer and the ILI9431 display to work.

-macke- · #7 Post by **-macke-** » 04 Jun 2020, 08:10

Just install ESP_Easy_mega-20200426_custom_ESP8266_4M1M.bin from "Release mega-20200426 "and you will find both ILI9341 and MQTT-import. Works fine

Quart · #8 Post by **Quart** » 04 Jun 2020, 13:45

Thats great.
Got it working.
On my other displays I can show data from MQTT easy with sttings in the display menu.
Now it seems like Commands must be use for getting text on display.
How do I get the display show example temp if I got MQTT imprt setup like this

-macke- · #9 Post by **-macke-** » 05 Jun 2020, 17:40

I'm updating my display with a Python script running on another server...

But it should work with rules...

I think it should be something like this... but I can't get it to work...

on Clock#Time=All,**:00 do //update every 10min

SendToHTTP http://<yourIP>,80,/control?cmd=tft,txtfull,0,0,2,RED,[MQTT#Value]

endon

Quart · #10 Post by **Quart** » 05 Jun 2020, 19:14

Thanks !!
Tried just running this command from the esp.
tft,txtfull,0,0,2,BLACK,Utomhus temperatur [imp#t] C

In this case I got.
Utomhus temperatur 12 C

Now I need it to on a new line display

tft,txtfull,0,0,2,BLACK,Rain [imp#rain]mm

Can you share you script ? I have a ubuntu serer upnrunning so I can easliy make it run som python script

-macke- · #11 Post by **-macke-** » 05 Jun 2020, 19:29

Great!

Just change here for a new line... you set the position pixel by pixel.

tft,txtfull,0,15,2

0=X axis
15=Y axis

If this doesn’t help you I had to clean up my script a bit before I can share it

Quart · #12 Post by **Quart** » 05 Jun 2020, 21:53

Once again, thanks !!
I have got it working perfect when sending commands from ESP Easy
tft,txtfull,1,1,2,BLACK,Utomhus temperatur [imp#t] C

But when trying this from Chrome it just displays the text [imp#t] C and not the value from MQTT
http://192.168.1.102/control?cmd=tft,tx ... peratur%20[imp#t]

-macke- · #13 Post by **-macke-** » 05 Jun 2020, 22:45

Good to hear it’s working

You can’t send that commando from another browser. The browser don’t know what that is [imp#t]

Quart · #14 Post by **Quart** » 06 Jun 2020, 11:55

Sorry for more questions.
You are right, browser dont work.
Runned commands from curl and it works.
All except the most important, the MQTT import values

Tried this but only get errors
curl http://192.168.1.102/control?cmd=tft,tx ... emperature [imp#t]

It displays Temperature (just the text and no values)

-macke- · #15 Post by **-macke-** » 06 Jun 2020, 13:13

Here is my python script. So can you try if it works for you aswell...

Place all files in same folder. Then you had to do some small changes in main.py before you run main.py

I changed IP settings and also found some "f" capital ifront och urllinks.
But now I got his message:

I am no programmer but what I can see there is no request done until it runs further along the code.
Maybe I shall move the line "import request" down the code ?
Or I am doing some other misstake?

-macke- · #17 Post by **-macke-** » 06 Jun 2020, 14:03

Sorry, forgot to mention that.. you need to install the module requests

Pip install requests

Yes done that.
Now I am struggling with the esp_values
This is how my sonsors in json looks like on my ESP.

-macke- · #19 Post by **-macke-** » 06 Jun 2020, 14:34

you just hade change these values... for example: ['Kwh/Day'] should be ['rain'] in your case and so on...

kwh = esp_values['Kwh/Day'] #add value names here...
temp_outside = esp_values['TempOutside'] #add value names here...
temp_bedroom = esp_values['TempBedroom'] #add value names here...
soil_sensor = esp_values['Moisture'] #add value names here...

I have used python 3.7 so could be that...

Quart · #22 Post by **Quart** » 06 Jun 2020, 15:42

YYYEEEESSSSS !!!!
It works.
Seems like it was the Python versions that was wrong.
Did this for getting it to work.
1. Removed Python 2.7 and installed Python 3.8
2 Extracted your script and did nothing to the files except
a. Inserted ip-adress in main.py
b. added my sensor values ex. rain in main.py

Thanks -macke- for your time and support !

Already have got a excellent dashboard with a 2.4" screen.
Is it complicated to have it change between different dashboard?

Planning to use these "bigger"screens to take the place from my other 4-5 smaller screens.
And it would be nice to have like say 3-4 dashboard that the esp is displaying.
1.Temperatures and humidity both inside and outside
2. Rain and wind, today, yesterday, this week, month and year
3. Energy consumption, now, last 24h for different devices.
4. Weather forecast

I can get all data from my MQTT server

-macke- · #25 Post by **-macke-** » 06 Jun 2020, 19:49

You can add four different MQTT "device'" and the script will found all values if you are using unique value names.

Then you just had du add a clear screen and add a timer ( time.sleep(sec) ) before switching to next dashboard.

Hi there,

I have tested a lot with this plugin. I tried to define also fonts for the display.
I updated the Plugin in order to use 7 segment fonts. If usefull i can try a push request for an update.

_P095_ILI9341.zip: (14.5 KiB) Downloaded 515 times

In order to use new fonts you can copy the fonts (Seven_Segment18pt7b.h, Seven_Segment24pt7b.h) to the path of the distribution before compilation

.... ESPEasy_mega-20200426\source\.pio\libdeps\test_beta_ESP8266_4M1M\Adafruit GFX Library_ID13\Fonts

Command: tft| font, <fntnumber> 0 standard, 1 Seven_Segment24pt7b, 2 Seven_Segment18pt7b
Example in rules:

Code: Select all

on System#Boot do
    tftcmd,clear,black
    tft,font,1
endon

Maybe you can give feeback on the change if usefull or not.

kind regards
Chris

Hi Friends,

I have trouble with the original lolin 2.45 Touch tft https://docs.wemos.cc/en/latest/d1_mini ... t_2_4.html configuring for ESPEASY

It just shows a blank white screen and doesnt react on any tft/tftcmd

can someone show me his plugin settings to compare?

Whats about the jumpers on the bottom of the PCB something to adjust here?

Hi
I tried to fiollow this but unclwear to me.

2 steps.

1. SPI setup in Hardware section for GPIO

Code: Select all

Note: CLK=GPIO-14 (D5), MISO=GPIO-12 (D6), MOSI=GPIO-13 (D7)
Note: Chip Select (CS) config must be done in the plugin

and 2nd on device:
TFT CS: but which pin are those ? is this the CS pin reference in Hardware setting?

are thos the pins reference in :
https://petergodwin.wordpress.com/2016/ ... 266-board/

Code: Select all

Pinout:
SCK #14 – D5
MOSI #13 – D7
MISO #12 – D6
CS #4 – D2   ->   is this TF_CS from device
DC #5 – D1    -> same hier TF_DC from deviceplugin

is reset pin needed?

Thanks for clarification

Best T

Ath · #36 Post by **Ath** » 27 Dec 2020, 17:32

Pinout seems to be OK as you suggest. (The text on the PCB is not always exact the same, so a little interpretation is required)

Reset pin is usually not needed, but some devices like it to be used when the device is getting a soft-reset (sorry, a bit vague, but it is hardware dependent). If you have a pin available, then you can use it.

When getting the latest released firmware (today) it includes the plugin for XPT2046 touchscreen that is mounted on many of the ILI9341 displays. If you use a 'display' version of the .bin files, you get both included. The touchscreen requires its own set CS and DC pins, but shares the other SPI pins. Even a Wemos D1 mini (clone) has enough pins available to connect that combo\, and still leaves a few for some (I2C) sensors.

Hi,
thanks

will check.

already using the latest firmware from today.
maybe display is wrong. will double check.

The touchscreen requires its own set CS and DC pins, but shares the other SPI pins

this is the serial bus? so same pin on wemos, right?

Ath · #38 Post by **Ath** » 27 Dec 2020, 19:28

Multiple devices can be connected to the SPI bus, that has at least a master (the ESP) and at least CS is used per (slave) device to allow it to use the bus. Many devices also need a D/C (data/command) line to be controlled correctly, and some use RST to be reset in concordance with the master. MISO (master in slave out), MOSI (master out slave in) and SCLK (serial clock) are connected to all devices.

You may need to connect power to the backlight (led) on the board to be able to see anything on the screen. Connecting it directly (no resistor needed) to VCC should be fine for testing, when connecting it to a gpio pin, you can control the brightness using the PWM command (0-1024) or just turn it on (1) or off (0) with a GPIO command.

Hello everyone,

from new espeasy user.
I made a few things with esp modules based on espeasy.

But i have a little problem with ili9341 display because it doesen`t work, i got only white display. I have version without touchscreen and it is 2.8".

I upload ESP_Easy_mega-20200426_custom_ESP8266_4M1M.bin on wemos d1 mini pro.
My connections are:
Vcc - +5V
GND
D4 - reset
CS - D0
D/C - D8
MOSI - D7
SCK - D5
LED - 3,3V
MISO - D6

I have enabled SPI interface in espeasy.
When i sending command:

control?cmd=tft,txtfull,0,50,2,BLACK,Utomhus%20temperatur%20

i get display working.

Mqtt reading working normally and shows temepratures in edge browser.

Can someone please check what i`m doing wrong.

Regards Sammy

Ath · #40 Post by **Ath** » 24 Apr 2021, 13:00

You should probably power the VCC of the display from 3V3, not from 5V. (At least that's how I've powered my tft displays)
Not sure if it can handle 5V, but the other signals are all based on 3.3 V, so that's not a good match.

And you could use a more up to date build of ESPEasy, the one you are using now is over 1 year old, and many improvements have been made. You will need a 'display' build to have the ILI9341 plugin.

qwerty_21 · #41 Post by **qwerty_21** » 25 Apr 2021, 11:25

Hello,

thanks for replay. Ok i flash last version of espeasy 20210223 and as you mentioned i need to compile new bin file with included ili9341 plugin. Because in custom version is not included.

But from this point things get harder

When i try to compile espeasy with arduino i got errors: ESPeasySerial.h.
I put this library into folder with espeasy.ino but still get error.

I know for most of users who are familiar with programming this is easy but for me is a little bit harder....

Thanks for help

Arduino IDE has been a PITA ever since I've tried to use it (> 10 years).
Can I persuade you to use VSCode with PlatformIO for compilation? I can't see why ppl want to stay at the archaic Arduino IDE if you can have a modern and up to date build environment

What do you currently have in your rules?
Can you get anything to show on your display using commands you can enter via the Tools page?

See: https://espeasy.readthedocs.io/en/lates ... #p095-page
There are some examples you can try to make sure your display is working.
