Hello,

I want to use the beep function with my STM8L Discovery.

After writing the program to STM8L, I connect the a piezo speaker between PA0 and GND.

The program is as following:

// Initialize

BEEP_LSICalibrationConfig(16000000);

BEEP_Init(BEEP_Frequency_1KHz);

//Beep

BEEP_Cmd(ENABLE);

delay_ms(200);

BEEP_Cmd(DISABLE);

But it doesn't work.

Do I need something another command on Initialization process ?

I know the PA0 is connected to the SWIM. Is it affect something bad for the beeper function?

Perhaps you need something like this:

CLK_PeripheralClockConfig(CLK_Peripheral_BEEP, ENABLE);
