This commit is to cherry-pick all fixes in the reverted commits to make future GPIO related fixes be as easy as possible. These also contain small fixes which were in the reverted commits, but not really related to the issues for which this revert is meant.

You should try to use GPIO 12...16 since these generally aren't used.
|
|
The recommended tone range is 20 Hz ... 13 kHz.
|
|
Up-to 40 kHz should be possible to generate, but will be inaudible for humans.
|
|
Frequencies above 30 kHz are not stable and will likely crash the ESP.
|
|
|
|
Duration is set in ms.
|
|
|
|
N.B. tones with a duration less than 50 msec will be blocking.
|
|
Longer duration will use the scheduler, which may cause some fluctuations in the duration.

``rtttl,<gpio>,<value>``

GPIO: 12 ... 16

Value: d=<duration>,o=<octave>,b=<tempo>,<notes...>

|
|
You should try to use GPIO 12...16 since these generally aren't used by ESP internal functions.
|
|
N.B. Playing a tune is blocking for as long as the tune is playing.
|
|
|
|
Value can be defined like <name_of_melody:duration,octave,beat,notes....>
|
|
|
|
For example:
|
|
``rtttl,14,test:d=8,o=5,b=180,c6,b,c6,p,g,g-``
