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 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.

Thanks for your information. I just want to know one more information like how the memory mapped mode is used. I want both flash and RAM memories should be considered as internal memory. Is it having two different addresses for memory mapping?
