Tone() not working on SAMD51

[RAyWB]

Just tried to use Tone() to generate a simple square signal, but nothing happens. tried several boards , itsybitsyM4 , GrandCentral ,MetroM4 ,same situation.

think it should work just using:

void setup() { pinMode(9,OUTPUT); }

void loop() { tone(9,1000,20000); noTone(9); }

to generate 1 KHz square signal on pin9 for 20 seconds.

can you please check what´s wrong?

hi can you try older versions of the board support package, and tell us wher eit stopped working? that would help figure out what happened that made it stop :)

Hi , it stopped working on change from 1.5.3 to 1.5.4 1.5.3 works

[ladyada]

ok thanks @hathach can you maybe look?

[RAyWB]

seems not to be related on tone.cpp , copying tone.cpp from 1.5.3 to newer version doesn´t help. sorry for no more ideas as I´m not a pro in coding.

Thanks for reporting the issue, I will try to check this out as soon as I could

I confirmed the issue on SAMD51, it even seem to cause the MCU to be hanged as well somehow. Looking into it now.

Hi , it stopped working on change from 1.5.3 to 1.5.4 1.5.3 works

Update: Thank to your report, I am able to narrow it down to a single commit, will try to fix it asap.

@RAyWB PR #257 should fix this issue, please try it out and let's us know your result.

Tone() checked on GrandCentral and ItsyBitsyM4 , works ! Thanks for fixing that issue
