The control scheme in this design is pulse width modulation(PWM) with pulse frequency modulation(PFM). The PWM module is similar to conventional design except its ramp signal with a variable frequency ...

You need to resample your output to use 32 bits e.g. with the help of a NumberFormatConverterStream: This module provides an I2S DAC with a mono amplifier and you just need to connect a speaker.

The APB PWM Module is a standard APB peripheral that generates a programmable duty cycle output signal. The frequency of the output waveform is eithe ...

Figure 2. Programmable H-bridge circuit. Through modifications on a series of codes in the programming module connected to the IGBTs, four specific sequences of PWM voltage waveforms were generated to ...
