Fails to run in Wemos D1 mini

[dakky]

I tried to have this running on a wemos R1 mini.

When starting the module, i get a stack trace:

3fff13b0:  feefeffe feefeffe 3ffe8550 40100f51  
<<<stack<<<

 ets Jan  8 2013,rst cause:2, boot mode:(3,7)

I tried to debug it and the error happens somewhere at my fork:
[https://github.com/dakky/WordclockV3/blob/debugbranch/src/ledfunctions.cpp#L546](see here)

Here is the serial output with my debug messages:

ESP8266 WordClock setup() begin
Starting timer
Loading configuration
Reading EEPROM config
Starting LED module
DEBUG: 1
DEBUG:1
DEBUG:2
114
DEBUG:2.5

Any idea whats wrong here?

oh btw: the wemos has nothing attached to it yet. Just powered by usb.

update: i managed to "decrypt" the stack trace:

Exception 9: LoadStoreAlignmentCause: Load or store to an unaligned address

it points to this code fragment:
currentDWord = buf[i >> 2]; in ledfunctions.cpp

I had the same issue, fixed by

• updating all arduino libs to latest version (except for arduinojson, which should be on 5.13.2)
• adding "attribute((aligned(4))) " to line 29 of hourglass_animation.h, so it reads
  static const uint8_t __attribute__((aligned(4))) PROGMEM hourglass_animation[HOURGLASS_ANIMATION_FRAMES][NUM_PIXELS_ALIGNED] = {

now i could succesfully compile and run without exceptions. Next is debug the web interface, cause it does not appear i get:

This is not an issue. The sketch data was not uploaded. Can be done using this link

i had several issues with the code, most importantly loosing network connections and watchdog resets.

i am now fixing them one-by-one, cause i reallly like this project. Happy to make a PR. My fork is here
