Hi, I am evaluating MEMS microphone for our application. I am using on board microphone MP34DT01-M in STM32F779NI-EVAL. I am using DFSDM example in STM32F7cube package and able to hear the speech. Now I want to filter the frequencies higher than 1KHz...
The HAL driver, HAL_HSEM_IRQHandler() disables itself by clearing bits in it's IER register. I don't want it disabled so I have to re-enable it in my HAL_HSEM_FreeCallback(). Is it desirable that it is disabling itself? I'm using the STM32H755.
Hi!I would like to store files on an SD card that are transmitted via HTTP POST (lwIP HTTP server). The files are correctly transmitted (hash calculating on both sides, the hashes are equal) and then written out to the card. But the content of the fi...
Here is the code in question:HAL_StatusTypeDef HAL_ADC_Start_DMA(ADC_HandleTypeDef *hadc, uint32_t *pData, uint32_t Length) { HAL_StatusTypeDef tmp_hal_status; #if defined(ADC_MULTIMODE_SUPPORT) uint32_t tmp_multimode_config = LL_ADC_GetMultimode...
I've found a bug in the ENABLE_SCRATCH_BUFFER implementation for sd_disk_io when using fatfs.When this option is enabled, the code initially checks to see if the buffer is 4 byte aligned, and if it isn't aligned (quite often the case with fatfs) then...
Hi everyoneThanks for read my topicI tried to record the sound, I managed to record the sound at a sample rate of 8 kHz. this is my code it works great. But I need more sample rate like 11kHz or 16 kHz, I do not know how I can increase my sample rate...
Dear Sir/Madam, I have two question to better understand the Embedded bootloader of the STM32F7 Microcontroller and relevant configuration with respect to the Silicon Revision.Is it possible to perform an overwrite of the embedded bootloader programm...
Hi,I am working on KSZ8563 3 port ethernet switch. I can communicate with KSZ via MDIO but Lwip udp example is not working. Controller is STM32H753ZI.example link : https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-a...
