Would it be possible to have additional Unicode Blocks (e.g. Latin Extended-A/B, Arabic, Cyrillic, etc. subsets) in your oleddisplay.squix.ch tool? I understand that not all fonts have all subsets, but at least the ones that have (Roboto, opensans, Noto, etc have full subsets) would help to localize the weather tool. Thanks!

I bought the variation without touch.
Where can I get the source code?

Is it necessary in weathericons.h to add/round picture width pixels to /8 and append extra "black" bit rows to the end of the array instead of just round to /4 - still full byte?
Example, a10px X 2px. picture containing totaly 20 points can be converted to 8 or 6 bytes with same display result:

 //8 bytes for 10 to 16px width rounding as per weathericons.h, do we really need the last 2 bytes ?
  0xe4, 0xe4, 0xe0,
  0xe4, 0xe4, 0xe0,
  0x00, 0x00 

vs. (as converted by this tool)

  //6 bytes, 10 to 12px rounding 
  0xe4, 0xe4, 0xe0,
  0xe4, 0xe4, 0xe0

Both arrays will be displayed exact same way on the screen by MiniGrafx ' drawPalettedBitmapFromPgm()

For correct connect to WiFi after reset please add 2 string into

void connectWifi() {
WiFi.disconnect(); //must be added
WiFi.mode( WIFI_STA ); //must be added

thanks!

Hello Guys,
I made the project with ESP8266 (NodeMcu) and 2.4 inch display but I don't have any information regarding the weather forecast on the display.
I change the setting.h, API key,
but nothing.
Anybody a solution?
Thank you

Just thought that it might be useful to attach a DHT22 sensor to still free D0 (GPIO16) port in order to measure an actual room temperature and humidity and to display it at 3rd carousel frame for example. Or to add a still reserved touch screen functionalty (XPT) in order to trigger in between carousel forecast frames and fixed indoor conditions frame. It might be also good to indicate a city name somewhere on the screen in order to know which place weather it is. Also miss bmp moonphases in the new release, The present graphic ones look quite simple.... I think that all of above will increase functionality and look and feel. Is it possible to update the code this way? Many thanks!

Hi,

thanks for this great project! I built a weather station a couple of months ago and it's been working great until about 4 days ago. Now it doesn't display any icons. The text is fine, but no bmps. On the serial terminal I see that they get downloaded and also load from the file system, but they don't get displayed. Any hints?

thanks,
-Christian

I'm not sure if this is an "issue" or that I do not understand something.

When uploading code via Arduino IDE, weather station Color works fine, connects to my network and pulls down data, displays great. Works great.

I am only connecting via micro USB - no battery. When I unplug, and replug, unit loses memory and requires re-uploading the program via Arduino IDE.

Do I need to always keep a li-po cell on the unit? Or is there a setting that I just do not see to keep the settings after power down?

Thanks

Daniel,

Thanks for publishing this neat project. I used it as a quick test for a 320x240 ILI9341 connected to an ESP12 and was very impressed.
Like you, I'm now also a great fan of PlatformIO and use it for all my (mostly unfinished) projects. I'm running under Linux, so there was/is one small problem with the build. The Arial font library files are named inconsistently. This probably doesn't affect Windows, but will cause builds under Unix or on Macs to fail. The problem is with the small (14-point) filename, where the filename is written "Mt", but referred to in the #includes as "MT".
It's easy enough for users to change the filename, but I just wanted to flag it, in case it trips up some novice maker somewhere.

Many thanks from Japan and my best wishes for a happy and prosperous 2017,

                         -John-

Hi all

I'm trying to adapt the code to the touch controller STMPE610.
I got it mostly to work.
Actually I'm trying to solve an issue regarding the area where the touch is touched.
I do not really understand what is going on during calibration process and what is beeing calculated in the getPoint function.
Can be someone give a short explanation of the calibration process and on the calculation in the getPoint function?

Regards,
Marcos

The present revision of the IL9341 connector (U2) has the square Pin 1 as a meaningless Tirq, for its mating board -- the mating board has the Square Pin 1 for Vcc, which is not unexpected

Please conform the Color Display Connector card to match the square pin1 of the IL9341 (the layout and silkscreen of which I assume is out of your control)

There is plenty of room and if this had been present, along with the 'square pin 1' contention, I could have avoided mis-assemlbing my kit [I soldered the connectors and will need to be de-soldering to re-assemble properly]

Not urgent, but a good think to keep in mind for the next run of boards

adding a revision date and version indicator comes to mind as good practice as well

I was seeing a vertical line to the left and right of the time on some numbers. It was only one pixel wide, but it was annoying.

My totally amateur fix... I added leading and trailing spaces, and the artifacts are gone.

String time = " " + timeClient.getHours() + ":" + timeClient.getMinutes() + ":" + timeClient.getSeconds() + " ";

I know it's not a proper solution, but it's an easy workaround.

It seems, that SPIFFS.open(filename, "r") returns 0 and not NULL, if it can't find the file.

At least my compiler gives me a WARNING:

src\GfxUi.cpp: In member function 'void GfxUi::drawBmp(String, uint8_t, uint16_t)':
src\GfxUi.cpp:107:49: warning: converting to non-pointer type 'int' from NULL [-Wconversion-null]
if ((bmpFile = SPIFFS.open(filename, "r")) == NULL) {
^

and when I change it to:

if ((bmpFile = SPIFFS.open(filename, "r")) == 0){
Serial.print(F("File not found"));
return;
}

the compiler is happy and shows no WARNING.

Maybe it helps, to get the code with a warning less...

how to wake up from sleep. Actually only reset works - by intention? Tapping on display would be nice.

Please add Json Streaming Parser (by Daniel Eichhorn) to the list of required libraries in the esp8266-weather-station-color project.

Please continue your awesome work. I have some personal projects based on them I use everyday.

I have some issue with the calibration of the touch screen. it appear that x and y are reverse. hardware or software issue ?

I've been using your old .ino on a 2.2tft for a year at least now and its been great. I noticed all these new updates, and in the new settings there is "define HAVE_TOUCHPAD". Does this mean we can use it without a touchpad? So far it seems to just cycle through the screens.

Also, I had to remove the D from the pin designations in the settings file for it to compile.

Short time after midnight, let's say 00:05 or even 00:20 the date is not updated and shows still the date of the previous day. Short while after it is updated as expected.

Hi There,

Just wanting to find out if India timezone can work on this device. That is UTC +5.30 hrs. I did a bit research across posts, it seems like the +30 mins is not supported by the library. Has there been any update to this.
This is a really interesting project and would like to gift the project to a friend from India.
Thanks

This idea was supplied by Andy here: https://support.squix.org/5/in-your-next-update-could-you-add-a-screen-saver-stand-by

configTime(UTC_OFFSET * 3600, 0, NTP_SERVERS); can take several seconds to update the system clock.
If time / date is displayed during this period, it will be zero-ed.

Suggestion, in drawTime() prevent the display unless the date is correct

if (timeinfo->tm_year > 116) { // valid, if the year is > 2016

First i build weather station with with small OLED display. Nice.
Now i build weather-station color. Great. Thanks a lot!
But the carousel from weatherstation color change pages with jumps and is choppy while at the small device it runs very smooth. That gives problems with the WAF :-)
Is there an error i made or an option to optimize the page-change?
Where i can set the time used for page change?

I read your description of the Continuous Delivery Pipeline, and noticed how WiFi Manager allowed the router password to be removed from code. Moreover, it looks like the router information is stored in flash, so it can be reused.

Have you thought about acquiring Weather Underground, ThingSpeak, and DST settings via browser connection (once WiFi is configured) and storing that information in flash too? This would make the code completely portable. I'm going to look into it, but it may take awhile with my coding skills (new).

Hello, after installing on your WiFi Color Display Kit the sketch hangs her:

[HTTP] GET... code: 200
start document
[HTTP] GET...
[HTTP] GET... code: 200
start document

DST Rules Updated:
DST Start: Sun Mar 12 02:00:00 2017
DST End:   Sun Nov 05 01:00:00 2017

Screen displays nothing has a slight flicker ( also when plugged in to adequate power supply)
Any ideas would be welcomed..

Great project though!!

The 3 API calls can be combined into one by catenating the requests into one URL like this /conditions/forecast10day/astronomy/

Maybe I and Arduino IDE do not understand something in C, but how can you comment such assignments, previously #defined as constants?
WIFI_SSID = value;
WIFI_PASS = value;
WUNDERGROUND_CITY = value;
etc.

Where can I download Carousel.h?

Hi Daniel

It seems that in the process of enhancing your program one of the basics may have slipped through the cracks.

Just curious why the WiFi credentials (SSID and Password) aren't specified in settings.h or by definitions at the top of the .ino file?

To get connected I had to scroll down to line 166 of the .ino file and enter those credentials. Did I miss something?

Don

Hello, the display ILI9341 has a slot for an SD card. If you can not use this option,
To put the images for the weather and the moon phases there?
Then they do not need to be loaded from the Internet every time.

greeting
Dirk

My compiler shows me the same warnings for the following lines: 92, 148, 149, 153, 299, 306

Example (line 92):
ui.drawString(120, 160, "Connecting to WiFi");

WARNING:
.../src/main.ino: In function 'void setup()':
.../src/main.ino:94:47: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] ui.drawString(120, 160, "Connecting to WiFi");

When I change it to:
ui.drawString(120, 160, (char*) "Connecting to WiFi");

No WARNINGS at all.

It seems, that drawString() needs a pointer and not a string.
It is still working with the string, but the cleaner solution with the pointer.

Maybe it helps for a cleaner code.

Got it working, but it seems the script is not retrieving the info from wunderground, since the weather shows 0°C and the screens cycle super fast. API key was set and manual requests from my browser display all the info needed (eg http://api.wunderground.com/api/MY API KEY/conditions/q/USA/NEW_YORK.json).

some picture not ready

I checked out latest version(#e71c540).
And I got this error while building.
How can I fix this?

(I upgraded libraries on arduino library manager, and removed Adafruit ILI9341 library in arduino libraries folder)

Any plans to tweak the code for the esp32?

Did setup everything today....seems to work as the BMPs are uploaded and I can see day+time....

But icons are not recognizeable at all....i can see the Temp correctly...I also can see SUN 5/15 MON 7/17 and TUE 7/17.....so very strange.....the dates look strange....but the TOP date with time is correct...

At the bottom i can see SUN and Rise/set time....also MOON and two values....but no icon for both of them....reset does not change anything.....

Any idea what is wrong....

Weather Station was found to be broadcasting its SSID unnecessarily

Resolved by adding WiFi.mode(WIFI_STA); to turn off the Access Point Broadcast, see below.
Also added WiFi.hostname(WIFI_Hostname); to provide a recognizable network host name, this requires the addition of #define WIFI_Hostname "Weather Station" in the settings.h file

void connectWifi() {
  if (WiFi.status() == WL_CONNECTED) return;
  //Manual Wifi
  WiFi.mode(WIFI_STA);
  WiFi.begin(WIFI_SSID,WIFI_PASS);
  WiFi.hostname(WIFI_Hostname);
  int i = 0;
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    if (i>80) i=0;
    drawProgress(i,"Connecting to WiFi");
    i+=10;
    Serial.print(".");
  }
}

Hab almost everything in German converted, only Forecast window shows me weather still in English .We are days in German. And in the main window above the date is in English how can I change that.
http://api.wunderground.com/api/apikey/forecast10day/lang:DL/q/Baunatal.jsonShows me the weather in German.
What am I doing wrong?
Everything else is in German and the comments I have also translated

I finally got around to installing your touch update today. Very nice.

The IS_METRIC setting works as expected for the current temperature, but the forecast temperatures always seem to be in C regardless of that setting.

http://www.squix.org/blog/wunderground/chancetstorms.bmp There is nothing at this address. Does this icon exist? Instead, it displays an empty space.

Hello,
I just want to ask if there is some way for generating images and icons to progmem palleted arrays, so it will be correctly displayed by minigrafx library.

thanks

How do you go about rotating the screen to landscape? I have looked and I am not really seeing where to configure that.

Hi,

I experienced some problem with screen brightness appeared due to direct connection of the display LED pin to the GPIO of ESP8266. Obviously the current of the GPIO is not enough to make a screen bright enough especially in the natural light environment. Moreover the particular GPIO15 (D8 at D1 Mini) might be overloaded and killed as a result with an excessive current consumption. Therefore I propose a simple schematics to avoid this situation and to make a screen much brighter. The only thing is that relevant code should be changed a little as now this port works in reverse logic:

// The LED pin needs to set LOW // Use this pin to save energy // Turn on the background LED pinMode(TFT_LED, OUTPUT); digitalWrite(TFT_LED, LOW);

Also in case of energy saving requirement it might be good to use an ADC (A0) pin at ESP to connect an LDR (light dependent resistor) to adjust the screen brightness in such a way that it goes brighter with natural light presence and dims out in the twilight or darkness. A calibration of LDR is needed to provide the necessary voltage readings at ADC pin and set up of the corresponding brightness levels of the screen.

On the last page of the Forecast display the last entry has an icon, cloud with ? mark which is not correct.

There have been sever weather alerts in my area the last two days and my weather station color will not boot. It crashes and reboots when it gets to the updating alerts section of the updates.

I commented out that portion of the code, and it boots fine.

/* drawProgress(90, "Updating alerts..."); WundergroundAlerts *alertClient = new WundergroundAlerts(); alertClient->updateAlerts(alerts, MAX_ALERTS, WUNDERGRROUND_API_KEY, WUNDERGRROUND_LANGUAGE, WUNDERGROUND_COUNTRY, WUNDERGROUND_CITY); delete alertClient; alertClient = nullptr; */

I downloaded the json file from wunderground and it is 24KB in size. I have MAX_ALERTS set to 1.

Let me know if any additional info will help.

After reviewing the code, am I correct in you are using Weather Underground as the time source for the clock being displayed?

Hi, I would really appreciate some notifications shown on the display. Is there something on the way?

Wishes
