STM CircleOS forum / Buzzer and schematic

Hi, I was wondering if the buzzer can be turned off in firmware, or if not maybe in hardware. Would this be possible if I put a switch in series with R30? (just a convenient solder point...)

thanks

At least, you could launch an application that turns off the buzzer (by recoonfiguring the toggle output mode).

Occasionally when I execute some applications on my STM32, the buzzer will go constantly until the app ends. I'm doing some taylor series calculations to determine sine, cose, ln, and other functions. It seems that if the loop takes a while, it beeps until the whole app is complete. Is there any way around this? I have included the line to turn off the buzzer several times in the code and it still does it. Any help would be greatly appreciated.

Thanks!
