The buzzer pin of STM8L051 shares the same pin with the swin debugging port. Although the debugging function cannot be used when beep is used (after the program is downloaded, disconnect the debugging swin and restart it to output), the program can still be burned into the MCU. (**Note** You can use the beep function without setting the option bit)
Here is the code for the library function:
void BeepInit()
{
// BEEP_LSClockToTIMConnectCmd(ENABLE);
CLK_PeripheralClockConfig(CLK_Peripheral_BEEP,ENABLE);
// BEEP_LSICalibrationConfig(38000);
CLK_BEEPClockConfig(CLK_BEEPCLKSource_LSI);
BEEP_Init(BEEP_Frequency_1KHz);
BEEP_Cmd(ENABLE);
}

STM32 timer realizes PWM output control of passive buzzer (HAL)
1. PWM concept and principle Pulse Width Modulation (PWM), short for "Pulse Width Modulation", is a very effective technology that uses the digital output of a microprocessor to control analog circuits. PWM principle diagram The figure above is a simple PWM principle diagram. In the figure, we assume that the t

STM8L051 RTC write time failed
I recently used STM8L051 to do a low-power project. I needed to synchronize the time between two nodes. As a result, the RTC did not wake up the microcontroller at the set time. At first, I thought it was because the crystal oscillator had too much error. I accidentally found that the time interval between the two wak

Learning MCU from Scratch (VIII) Buzzer Singing
The structure of the buzzer on
the microcontroller is very simple
As long as you give it a 0, it will "call". The principle of making it sing is very simple. The volume of the sound is fixed. By changing its frequency, it can make it produce different notes.
In the code, during the software loop delay process, a
