I2S Data stored in .wav file not playing correctly!

Hi I have ADAU1978 which is a quad ADC that gives I2S data which im trying to store in a SD card under .wav extension. When i do this i get a .wav file of size 8kB. When i try to play it with windows media player, it doesnt throw any error,but doesnt...

STM32F411/STM32F413: Enabling i-cache results in SPI read getting blocked

I am working with STM32F411/13 controllers from ST. And i observe an issue with SPI reads if i-cache is enabled. More details as below:I do have the FLASH PRE-FETCH enable set. And Flash wait states properly configured based on the System clock.And a...

MEM-to-MEM transfer using DMA (SRAM to FSMC/FMC)

Hi,As far as I remember, I've read something about that a while back. I was wondering if I can send data to a memory-mapped device (FSMC/FMC) in a continuous loop a byte per iteration using the DMA peripheral. Thanks

STM32F10x entering standby mode fails occasionally

Posted on October 28, 2016 at 02:11We use PWR_EnterSTANDBYMode library function to enter the standby mode. I have added line to enable WKUP pin. The STM32 enters standby mode most of times. But, sometimes(once in 25 or so times), it just reaches the...

can I use one timer to interrupt another timer (start and stop)

I want to generate 1 Mhz with one timer but I want to stop it for 1 ms and then generate for 5 ms.I see that there is instruction HAL_TIM_Base_Start_IT looks like I can start and stop one timer with anther, I am using Cube MX and keil.

STM32L486 mcu used as Master SPI, Zigbee device as slave. What configuration of SSM and SSI should i be using?

I am going through an existing implementation, where my MCU's(STM32L486) SPI1 (PA4(NSS), PA5(SCK), PA6(MISO), PA7(MOSI) is used as master, the slave device is a zigbee stack.Currently the master's SSL is configured as Software managed, (SSM=1, SSI= ...
