Hello dear community,I’m working on a USB sound interface, using a STM32F7 and an external DAC chip offering 8 stereo output channels.Most of the DAC are offering multiple serial data inputs ports. For example, the Analog Device ADAU1966A is offering...

Hello,I get an issue with the USB HOST configured on my STM32F2This USB HOST driver works well in my case, but it appears that the interrupt OTG_HS_IRQHandler is called too frequently (when I plug a device on the USB HOST post) and it's flooding my C...

Hello!I've been working with several STM32 parts since 10 years. I'm working for a company so due to confidentiality I can't share the schematic of the custom PCB, sorry.On the first batches of a new product, using a STM32H743BI, it appears that some...

Hello!I'm working on a STM32H743I use a USB DEVICE driver (pins PB14 and PB15) : only AF12 is possibleI also use a SD card driver (PC8 ... PC12) : only AF12 is possible(Alternate function mapping is described in the datasheet https://www.mouser.fr/d...

Hello dear community,I've started using STM32H743VGT6 on a custom board I've made.I'm testing the hardware now and I quickly detected that the temperature is really high (approx. 70°c on the top of the chip package).I have another board, based on a S...

Hi @SLasn.1 !Just found your very interesting thread about SAI and dual-line transmit. I'm new to SAI and it appears to be not the largely used library of STM32 users Have you found a better solution to the zeros buffers?PS: I've posted a related qu...

Hello,Thanks for your answers!The ref is stm32h743bit6 (package LQFP-208)

Hi everybody,Thanks a lot for all your explanation and ressources, that's very interesting. I confirm that having same alternate functions for different peripherals is working in my case.Have a great week!

Thanks for the AN5337 info! That's interesting. I've never thought about using a lower frequency. Every previous project using STM32F was running at max speed and the heat was low. Even my STM32H743 package running at 480MHz in a big package (LQFP-20...

Thanks!To be honest, I had trouble to find the right info in the H743 datasheet https://www.mouser.fr/datasheet/2/389/stm32h743vi-1760857.pdfToday I've found that indeed, with All peripherals enabled (that's closer to my case)frcc = 400MHzcache ONThe...
