[STM32G431KBU3 - USBPD] - Problem when trying to use another ADC

Dear all,I wanted to develop a USB Power Delivery SINK project using my STM32G431KBU3 MCU.For that reason, I have designed a custom PCB and follwed carefully ST's WiKi:https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:STM32_Advance_USB-Power_Delivery...

Audio performances of STM32L476JGY6TR

Hi!We are starting to develop a product based on an STM32L476JGY6TR.Part of the system would be dealing with a mono audio stream at 6kHz (sampling frequency).I've read in the datasheet that this ST chip offers some audio capabilities using SAI interf...

Bootloader: jumping to either App A or App B

Hello​I​ am considering the following approach of the Bootloader.​We will divide the internal flash into :1. Bootloader 2. App A3. App BFor App A or B we will have a version number. Bootloader will read the version numbers of both and depending upon ...

real time processing in STM32H750B-DK board ?

I am working on reading an External 3 bit parallel CMOS ADC (4-8 MSPS)(from MAX2771 board or Eva KIT) GNSS digital output through STM32H750B-DK board, Then transmit it over Ethernet or USB2.0 in real time through TCP/IP protocol continuously. then pr...

what's the possible to enter and execute DFU using the nBOOT0 / nSWBOOT0 / OBL_LAUNCH bits information?

Hello,I am using STM32L412RB.I have some questions about DFU.STM32L412RB BD is connected to a serial device and receives a specific command.After that It jumps to the corresponding ADDRESS to perform DFU.Occasionally, a failure occurs during the DFU ...

CubeMX, FreeRTOS, LwIP: SSL client hangs on infinite timeout take of semaphore inside LwIP ?

Hello,I've noticed and at last analyzed/debug the nasty situation, where my SSL client task suddenly "hangs" with no further action. I've analyzed the situation and it seems that it hangs on taking a semaphore with infinite timeout inside LwIP part. ...
