Problem Statement: Amplifying Low-Amplitude Audio Signal on STM32 Nucleo64 BoardHello STM community! I'm new here and seeking some guidance. I'm working on a project using the STM32 Nucleo64 board to create an announcement maker. My setup involves us...

I will try to scale the data, also I can hear the audio clearly so I don't think the problem is with generation of signal.

Yes, I measured it when data was being transmitted on PWM pin. I have added few lines so when the data is being transmitted to the pin from flash the onboard led turns on. Also I am using third party software for PCM data generation by converting aud...

I am using a 8ohm speaker. I know that the stm32 has limitation of 3.3V and I am using two stage amplifier (you may see the circuit in the other comment I have replied to). I am using GPIO pin PA0

I am using tim2 ch1 for pwm generation , the pin I am using is PA0 but I also tried with PC6 that is tim8 ch1. The main issue is that I am getting less then 1V on signal output (GPIO Output) and after this circuit that i attached , The audio is audib...
