I want to send audio samples (received via SAI1 from PDM MIC) to SAI2_SD_B as SPDIF out. It does not work, because: the DMA does not seem to write the DR in SAI2: the memory is filled with audio samplesthe DMA seems to run (I get the HAL_SAI_TxCpltCa...
Hi,Can someone clarify why some examples of boot to QSPI change the SCB->VTOR register in JumpApp function :SCB->VTOR = (uint32_t)Application_vector;JumpToApp = (pFunction) (*(__IO uint32_t *)(Application_vector + 4u));__set_MSP(*(__IO uint32_t*) App...
st released a spirit mp3 encoder in STM32CubeExpansion_Audio_V1.1.1. But I failed to call functions inside lib file lib_mp3encoder_cortex_m4_v2.2.0.a.Are there m7 version lib for my stm32h743 mcu?
Sure, here is the translation of your query in a polite tone:I am using an STM32L072CB to validate an HID device and I want to switch between Input Reports based on the PC settings, using different Endpoints. However, after sending the Input Report ...
Hi, i go to start SDMMC1 in STM32H753z, is any sample code? can please provide. in SDMMC i need to use FATFS APIs or SDMMC APIs ? i am confusing please help me. when i debug the below code i am can n't access it stop at f_mount() starting only....
Hi,I have a custom master PCB connected to a few slave custom PCBs via serial. In some systems they are connected via I2C and in other systems they are connected via RS232.They all run STM32 micros.I am looking for two out-of-the-box protocols with s...
Hi,I am developing on stm32l011 board and I am facing issue about UART interrupt. static uint8_t rxBuffer[32] = { 0 }; void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { /* Check if it is start command. */ if(NULL != strstr((char*) rxBuffer,...
Hello everyone,I am currently working on a project with the STM32U5A9 microcontroller and am trying to interface the W25Q64JV flash memory using the OctoSPI bus in QuadSPI mode. Despite extensive searches, I have been unable to find relevant example...
Hello Community,I'm working on a project and could use your help. I'm trying to make a sine wave with a changing frequency from 600 Hz to 5 kHz using STM32 microcontroller(STM32L073RZT) with 32 MHz as sysclk. This are my configurations. Where this r2...
In the next code I sample audio from the mic, play it to the headphones, then i process the data to get Mel-Spectrogram feature and then I feed the Mel feature into an AI model to recognize speech.when I enable the functions that calc the mel and the...
