Posted on February 17, 2016 at 17:58Hello,
I'm having a problem after enabling I2S3 in master receive mode, for aquiring data from a mems mic.
After calling HAL_I2S_Receive_DMA(), all other DMAs go to RESET state (all of them were READY).
I tracked down the problem, and this happens after:
/* Enable Rx DMA Request */
hi2s->Instance->CR2 |= SPI_CR2_RXDMAEN;
is executed (in HAL_I2S_Receive_DMA() function).
Anyone knows why this happens, or what am I doing wrong?
Thank you to all.
Regards.
