I would like to build the Audio playback and record example code of STM32F4 controller to STM32H5 controller. Could you please help me with feasible method to make it work. I am planning to use same driver code and middleware code of STM32F4. I have ...

I am trying to convert microphone PDM signal into PCM signal and i used external PDM2PCM library files (which is used for STM32L4 cortex-M4) for that, i am able to bulid it for STM32H5 controller. When i execute the blelow PDM_filter_init function i ...

I am using STM32H5 nucleo board and it is connected with MIC which gives PDM output based on analog input. I am reading the mic data using I2S protocol. To verify the received I2S PDM data, I am giving this data directly to DAC to get original signal...

I am trying to use second half of OCTOSPI pins in single memory mode by setting MSEL bit for QUAD SPI communication with Flash memory. Even though i set the MSEL bit to send the data through 7 to 4 pins, still data is going through the 3 to 0 pin onl...

I am using STM32H563-ZI nucleo board. I would like to add X-CUBE-AWS extension package with this Microcontroller. Could you please tell the procedure to integrate this with STM cube IDE?

Yeah, i made it work on the STM32F407-Discovery board.I am first planning port recording part alone. i have clear idea on I2S Audio communication but i dont have any idea porting USB code. Also Main difference is STM32F4 has micro-USB but STM32H5 has...

I changed controller for testing purpose. We are using STM32F4 - nucleo board, infineon digital microphone (IM73D122V01) and internal PDM2PCM libraryfor conversion. In I2S protocol we used input clock frequency 3.072 MHz and sampling rate 48KHz to re...

I am not able to proceed further, would it be possible to port STM32L PCM library to STM32H5 controller or not? or can i try some other STM32 PCM library to make it work?

If i disable the CRC feature also i am getting that same hard fault error. Could you please guild me how to use KeilHardFault.c file to debug the issue?

Nagarajan · 2024-07-29

I enabled the CRC feature as i was told it is a part of the procedure for PDM to PCM conversion. After executing the CRC_Lock() function it is going to hard fault error. I didn't enable the FPU.
