Here is the configuration I use:int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_ADC1_Init(); MX_TIM2_Init(); // configure PWM __HAL_TIM_SET_AUTORELOAD(&htim2, 1000); __HAL_TIM_SET_COMPARE(&htim2, TIM_CHANNEL_1...

Hi folks,I want to start ADC conversions on 2 regular channels of ADC1 block only after the voltage on one of the channels exceeds a certain limit, hence I'm using a watchdog feature.After the watchdog will be triggered, I need to store 5 consequent ...

Are here any example projects on how AcousticBF library should be configured exactly for PCM mode? There are plenty of examples for PDM mode configuration, but none for PCM, which is frustrating, since the documentation on this library is not very ex...

I'm trying to implement AcousticBF library functions and what I've noticed is that, when I configure it like this for PCM mode, 2 microphones:void Audio_Libraries_Init(void) { volatile uint32_t error_value = 0; /* Enable CRC peripheral to unlock ...

Hi,I want to create a simple device that streams audio from a PC to a loudspeaker via NUCLEO-L476RG board. The connection to a PC is implemented via USB connector on the X-NUCLEO-CCA02M2 board, which is plugged into NUCLEO-L476RG.I've configured the ...

Hi Philippe,Thanks for your time and trying to help.So far, I've figured out that the false values the ADC stores in its data register are all equal to exactly 4095. I've double checked that the ADC inputs are not connected to anything other than GND...

Yes, you're right about HAL_ADC_MspInit(). I've attached my project to this message.On my board I also disconnected PWM output pin (PA0) from the rest of the circuit and as I mentioned previously, ADC input (PA2) is tied to ground.

Yeah, but there is no dev board with exactly STM32G061G6U6 chip.

As a last test, I've commented out// HAL_ADC_MspInit(&hadc1);command, so no ADC pins should be configured and ADC can't receive any data from anywhere, however the issue is still there.

I've checked the PWM output pin, it is truly at 100% duty cycle. I've also checked that the duty cycle can be reduced to other values. It is possible, so PWM works properly. However, it doesn't change the situation, ADC still detects max values from ...
