Hi,I'm trying to capture a USB connection / disconnection event in STM32F722RE. The interrupt HAL_PCD_IRQHandler() is called when I connect / disconnect the device to the PC, but the flags USB_OTG_GINTSTS_SRQINT and USB_OTG_GINTSTS_OTGINT are never s...
I'm trying to set up a counter to capture the period of an input signal. I'm getting lost in the different CCMR bits. If it possible to do the following:wait for a raising edge on an input.on the raising edge, start counteron the next raising edgerec...

Dear all,I am on the process of switching to GNU GCC for compiling an already working project. Most of the functionality has been tested. There is a failing test though: The USB VCP drivers do not seem to perform good.The client side (PC-Windows) is ...
Hi again, Issues around the ETH-Peripheral of the H743 are not addressed for the first time here. It would be extremely helpful to have one example (simple as possible) with a kind of "guarantee" to run on a NUCLEO 743 Board "out of the box". This c...

In STM32 I see in the clock when i declare gpio clock also selected. why we have to set that clock,what is the advantage
Hello, I'm having trouble trying to program a STM32F427IGT6 uC using STM32CubeProgrammer command line or the API , sometimes it identifies the uC but never allows me to program it. I'm missing something? Should i download an external package for th...
We are using stm32L476 in one project where we need to access external SPI flash. I havesetup SPI clock speed to 10Mhz and it works without any problems, but at 21Mhz flash becomenon responsible. When I checked clock with oscilloscope I can see, that...
Hi,We tested to rewrite the data into STM32L433CC.May i know why this device is unable to program data in second time?If i use STM32F072, and it is able to rewrite the data in second time.What is the different?For example, i write the data at addre...
