Hi all,I'm currently working on a STM32H743. The idea is to use a SAI peripherals to read an Audio stream:The SAI is set to be a Master receive with a circular buffer and a DMAThe issue is that as soon as the HAL_SAI_Receive_DMA is called, then the c...
I need to take 10 samples (10 Hz) per second. How can I set ADC configurations on CubeMX. I use the lowest sampling time (2.5 cycles), but the values I convert and use in ADC change very quickly.Thanks for helps.
Hi - I'm learning DMA, and am having some trouble. (L4, but this applies to most/all STM32s)For SPI, the RM States this:"To close communication it is mandatory to follow these steps in order: 1. Disable DMA streams for Tx and Rx in the DMA registers,...
i am using stm32h743 microcontroller ,in this i am working on the uart in dma mode for receiver i am using circular mode and for transmitter i am using normal mode. the communication is working in the first time , when i am trying to transmit the dat...
We are looking for STM32F072RBT6 part but it is out of stock at many places. Can anyone suggest source for the same IC.Any alternative part suggestion would also be helpful. Thank you in advance.I am sorry if this is not the right place to post this ...
Hi, i'm trying to get a value from a microphone using HAL_SAI_Receive() in blocking mode. I'm trying to write a program that receives a value from the mic connected to the SAI block. The HAL_SAI_Receive() is called in an ISR but when the program is r...
On STM32F767 if the reference voltage sags would it cause an error on the ADC?. I have multiple adcs running and configured with a circular DMA buffer. I get an intermittent error that shows up once in days and it seems to be a DMA transfer error. T...
