Bugs in LL_RTC_DATE_Init

STM32Cube MCU package for STM32H7 v1.8.0Also exists in F7 version, probably others.To reproduce:enable RTC with LL code generationmake sure assert_param() isn't stubbed outSet a date in OctoberTry both BIN and BCD format, they both have slightly diff...

I can't program my STM32 through bootloader on a CAN Network, even though it works with a single target connected on the bus.

Hi all, I use 2 STM32F446RE boards. They communicate with a CAN bus.I get a little code that allows my boards to enter boot mode when it receives a frame with a specific ID.When one enters in boot mode, using a third board, I send a frame with ID 0x7...

Hello,I am trying to enter the system memory at boot time with the STM32G030 MCU. It has the BOOT0 line shared with SWCLK functionality, which is new to me compared to the STM32F* devices. I always entered the system memory in other devices by settin...

USB Battery Charging (BC)

Hello,When using an MCU with USB FS capabilities, do I need an external IC to be able if an SDP, a DCP or a CDP was plugged in ? Or can the MCU do the job ? Apparently yes, but I struggle to find evidence of this, especially in the datasheets or in t...

STM32 USB Isochronus endpoint problem

Hello! I have a problem. I created a USB audio device project in CubeMX. Then I changed the descriptors and related functions to get a device like a microphone. The device is detected correctly in the Windows system. But there is a problem: DataIn en...

HS USB Device Audio-In on STM32F769 Discovery issues. DataIn event is not fired every time, the setup command to turn the microphone on is received .

For a little background, i have modified the project to take audio data from a static file to eliminate any issues with interrupts from the mems microphones may have been causing though the result is the same. I have also added print statements to t...
