flashing MM
|

-----------
|
||||
|
||||
[MoonModules](https://mm.kno.wled.ge/) (MM) is a fork of WLED.
|
||||
It is often used to experiment with features that could then be released in WLED.
|
||||
It also includes numerous usermods, including the DMX IN support our board takes advantage of.
|
||||
|
||||
|
||||
Get the release:
|
||||
|
||||
~~~
|
||||
export MM_RELEASE="0.14.1-beta.30"
|
||||
wget https://github.com/MoonModules/WLED/archive/refs/tags/v$MM_RELEASE.tar.gz
|
||||
tar xf v$MM_RELEASE.tar.gz
|
||||
cd WLED-$MM_RELEASE
|
||||
~~~
|
||||
|
||||
Or get the latest source:
|
||||
|
||||
~~~
|
||||
git clone https://github.com/MoonModules/WLED MM_WLED
|
||||
cd MM_WLED
|
