Default “Ledmap.json” disregarded

[spblat]

What happened?

My application is a serpentine arrangement, with an extra/dummy LED between each row. There are 27 physical LEDs, arranged into a 6x4 grid. Prior to 0.16 I use ledmap.json to disable the three dummy LEDs so that the grid is rendered correctly:

{
"width": 6,
"height": 4,
"map": [
0, 1, 2, 3, 4, 5,
12, 11, 10, 9, 8, 7,
14, 15, 16, 17, 18, 19,
26, 25, 24, 23, 22, 21
]
}

To Reproduce Bug

• 27 LED strip, 0.15, 6x4 2d matrix
• apply ledmap.json above
• Three LEDs go dark every six LEDs, last three LEDs go from dark to active. This is the desired behavior
• Update to 0.16: last 3 LEDs go dark and the “gap” LEDs go active again, leaving the last three dark
• Revert to 0.15.4, ledmap works correctly

Expected Behavior

Treatment of ledmap should remain unchanged to allow definition of a serpentine grid with an unused LED between rows

Install Method

Binary from WLED.me

What version of WLED?

WLED 16.0.0-beta (2604110)

Which microcontroller/board are you seeing the problem on?

ESP8266

Relevant log/trace output

Anything else?

Thank you WLED team! ♡
