Hello STM32 Community! My I2S dma transfer worked perfectly on stm32f7x in the past, but due to time critical calculations i just started to continue the development on the advanced stm32h7 system. I use the same code, same initialization procedure a...

Posted on March 11, 2017 at 12:00Hello.I am working on a project where i collect the external ADC results through the I2S peripheral (using double buffer DMA).The algorithm works in the following way:- Once memory 0 is filled, interrupt occurs, a fl...

Posted on February 06, 2017 at 23:24Hello,I collect the ADC data through the I2S1 peripheral using DMA2Once1) i collected certain amount of results,2) the reception is paused with:HAL_I2S_DMAPause(&hi2s1);3) I send the data through UART4) then the r...

Posted on January 25, 2017 at 15:14Hello,i am working on a project, where i shall store the converted ADC data in a float fftChData[65000] array.(the ADC data is received through I2S1 and I2S2 working in a double buffer DMA mode)I got weird behavior...
