I am using STM32F446 Nuclero and STM32CubeIDE.I wrote a loopback code from I2S_ADC (PCM1808PWR) to internal DAC.MCU is slave mode (external clock to IS2_CKIN).I works fine. However, when I try to "Pause DMA" and "Resume DMA", I2S of MCU does not sy...

Hi, there!Please help me !!!I am testing Timer cascading with F411 Back pill on STM32CubeIDE.TIM2 [Master] ---> TIM5 (or TIM9) [Slave]There is no description on Periphral Interconnect Matrix feature in the STM32F4 manual (RM390), but I found the...

Dear Experts,I ported I2S RX and TX program from F401 to F302R8 Nucleo board. And I encountered **unexpected** phenomenon.When I use I2S for receiving data (Half-duplex, Master-Receive mode, 48kHz, 24bit data on 32bit frame), it works fine. That mean...

Hello,In Section 36. I2S Generic Driver of HAL document (UM1725), I found an incorrect or misleading explanation.In the explanation of HAL_I2S_Transmit, there is a "notes" below.-----------------HAL_I2S_Transmit (I2S_HandleTypeDef * hi2s, uint16_t *...

I wrote I2S Loop back test program. I2S2 as Master Transfer mode and I2S3 as Slave Receive mode. (Proto for ADC in and DAC out.)It works OK when 16bit in 16bit frame. However, in 24 bit in 32bit frame, DMA pointer etc. are corrupted.With step-by-ste...

Dear A.Scha.3,Yes, you are completely correct.My bypass code for this issue is the same as your comment.I keep DMA run, and control copying new data from buffer on and off using flag. But I think it is not cool solution, therefore, I asked to the e...

Dear AScha.3,Thank you very much for your reply.I am running MCU with Slave receive mode and PCM1808 with Master transmit mode with common master clock (48kH*256 =12.288MHz).What I need to do is stop DMA only. DMA is just transfer data from RX Da...

Dear Jan, Thank you very much for your kind and immediate reply. With your kind information, I found ITR table and found the scheme of interconnection differs among MCU models. I use to use F446 Nucleo but this time I tested on F411 blackpill, I refe...

Dear Mr. Houssem,Thank you very much for your kind mail.However, I found the reason of the article above last week.The same program works "almost" perfectly on F401, but does not run on F302. And only difference between them were I2S clock (fs).Prog...

Dear Nesrine, Thank you very much for your kind offer. However, I found the reason of this problem, and I sent the ST Community my request. Request to revise I2S section of HAL document. (UM1725)https://community.st.com/s/question/0D73W000000Unty/det...

I2S_DMAResume does not Sync in Slave mode. (CubeIDE)

Timer Cascade with STM32F411. Bug of F411 MCU?

CubeMX Generate wrong code for I2S Master-Transmit, or F302 has bug? (CubeMX ver 1.4.2 + STM32Cube_FW_F3_V1.11.1 + STM32F302R8)

Request to revise I2S section of HAL document. (UM1725)

STM32F4 Is this BUG? I2S LOOP BACK TEST FAILS in 24Bit Mode. Crush DMA pointer etc. (source code attached)
