STM CircleOS forum / newbie question: cant hear buzzer ?

alexholy · 2008-04-02 14:40:54

I received my Standard STM32-Primer today.
The hardware seems fine, including the buzzer - e.g. the maze game does indeed make noises.

So I set the CPU to MAX speed, and started the tutorial.

Specifically, I tried the toggle_with_circleos example on Page 11 of the tutorial.
I added the "BUZZER_SetMode (BUZZER_SHORTBEEP);" as instructed in the manual.
However, there are no audible beeps.

I single-stepped through the application and indeed the BUZZER_SetMode (BUZZER_SHORTBEEP) line is executed.

The circle OS documentation is also not really helpful in this case, it just states that "BUZZER_SHORTBEEP Make buzzer to bip for a short time" which is probably frenglish for "this call results in a short beep"

Any suggestions?
P.S.: I installed the most recent tools from this website, and the OS is 1.6

Where BUZZER_SetMode (BUZZER_SHORTBEEP); has been placed ? It should be putted exactly in the same place as described in manual. Try with OS v1.7. Is the buzzer not correctly soldered ?

Yes, obviously I checked if I placed the statement properly

I fixed the problem in the by hard-resetting the device (disconnecting USB and removing the battery jumper).
That did the job - it is now beeping as it should.
