Weather Station with D1 Mini Pro crash and loop

Question

Two weeks ago i received your interesting kit for weather color, after ISram issue, i read this support foroum and follow all recommendations using D1 2.4.2 core without success,  i'm in trouble  because the wemos d1 pro mini  included in the kit, for me didn't have really 16Mb, but only 4 Mb, and only if i choose Lolin D1 Mini R1 D1 (pay attention, not PRO) my arduino IDE 1.8.1 on windows10 compiles, and  seems  the Spiffs format say apparently ok. But i was never able to see touchscreen working yet
Now the question is that  after upload sketch  i see for  one second the Thing Pulse connect to wifi page,  then appear a white page and loop continously between wifi connect page and a blank page.

Tried also to modify XPT2046_Touchscreen.cpp and upgrade to 2.5.2 core as described on your support forum https://support.thingpulse.com/1040/have-an-error-isr-not-in-iram?show=1060#a1060

#ifdef ESP32
void IRAM_ATTR isrPin( void )
#else
ICACHE_RAM_ATTR void isrPin( void )
#endif


But as you can see on the attached log, it seems that after apparently right download pages from openweather, the cpu goes in crash and reboot and reboot again with the following final information extracted from the log:

Connecting to WiFi FRITZ!Box 7490/xxxxxxxxxx
.........Connected...Initializing touch screen...

Stupidly i soldered the wemos D1 to the board, so i'm quite lazy to desolder it and replace with one of my wemos d1 mini, (isn't first time i work with wemos, and never ancountered problems with spiffs and touchscreen as with this).
So i kindly ask an help to solve quickly this issue, knowing really step by step how configure and programming the D1 Pro provided in the kit and second question, why you declare on the kit an esp8266 wemos D1 mini Pro 16Mb, when it is only 4MB and on your docs, guide etc, you mention only D1 Mini 4MB for this beautiful project? thanks in advance

Comments

Kudos for trying to solve this on your own and searching in our forum! Let me address the questions one by one:

4MB vs 16MB: the factory put the wrong sticker onto the box, it's not a D1 mini Pro. If you work through our tutorial it correctly describes all the settings: https://docs.thingpulse.com/guides/wifi-color-display-kit/#select-flash-mode-and-flash-size

ESP8266 Arduino core 2.4.2: as per https://docs.thingpulse.com/guides/wifi-color-display-kit/#install-the-esp8266-toolchain you should be using ESP8266 Arduino core 2.4.2. The issue is caused by the XPT2046 touch library which doesn't support newer versions yet. Please leave a comment with https://github.com/PaulStoffregen/XPT2046_Touchscreen/pull/24 to motivate the author to finally release the fix that he already committed months ago.

As to the final problem:
- Can you rule out bad solder joints? Can you test connectivity as per the wiring diagram at https://docs.thingpulse.com/specs/wifi-color-display-kit/#wiring
- Please install the exception decoder to find the line of code that causes the crash: https://github.com/me-no-dev/EspExceptionDecoder

Answer 1

hello @all. resoldered all joint, reinstalled all software stack on another PC with arduino ide 1.8.8, installes EspExceptionDecoder (included missing xtensa elf---xxx--gdb-something missing) but same result, loop and loop again and never see nothing but the first connecting page. below the stack trace decoded, remain to verify all wiring connection and try to install libraries manually from github removing them from library manager as read in another thread in this forum for the same product :

let me know, thanks

Does your router support IP4 many new devices only support IP 6 on my Sky Q router I have thought o enable IP4 support, for example.

---

@G6EJD I agree, that's the smoking gun here if we look at the stacktrace. However, the output in the original description shows that the device was able to fetch some data from OWM.

Gianluigi, you can test/verify with simple sketches that don't write anything to the display.

Hello again, after hundreds of test, including perform  a factory reset of the wemos without success, definetely confirm the wemos provided is broken in some part. wathever project i upload, after a while he crash and restart. So with patience i desoldered the broken wemos and replace with one of mine with chip in metallic case (DOIT.AM brand) . This time it works with your recommended stack 2.42 board and so on. A pity the lack of upload image here, by the way take a look https://photos.app.goo.gl/SyNvpKXxAzPt19Vt6
Last problem now is the touch, nothing happens if try to touch every portion of screen, only the led blink. Any suggestion? thanks for your support till now

---

Do you know the providence of the screen? If purchased from Thingspeak then ok, if not then highly likely it has no touch support fitted, a fact that is well documented.

---

Hello G6EJD the screen is included in the original ThingPulse kit bought one month ago. Now the great news! All works like a charm with my mini D1, the issue with the touch has been solved after flashing once the firmware with (Tools -> Erase Flash ->Erase ALL FLASH CONTENTS option on Arduino ide). After restart, program launch touch calibration again and this time it save correctly the coordinates.  Thanks again for support and
I wish you a merry Christmas. bye
