Using STM32 VS Code Extension 2.0.1 to create empty project for STM32C0116-DK board.The generated startup_stm32c011f6ux.s file contains handlers in wrong (alphabetic ???) order: g_pfnVectors: .word _estack .word Reset_Handler .word NMI_Handle...

Hi, UM2970 for the STM32C0116-D says about CN1/CN5: "The extension connectors are available on the STM32C0116-DK Discovery kit to support flexibility in user applications." But, half of the CN5 pins are N.C.. Does anybody know, what extensions are av...

Hi,I'm observing GPIOA_MODER reset value 0x2BFF FFFF on my STM32C0116-DK, not 0xEBFF FFFF as written in the RM.My guess: because PA15 does not exist on that MCU hthKnarfB

In STM32CubeMX 6.8.1. (and before), there is an option to enter a custom path to the firmware. But, in contrast to what it says, I can only pick an absolute path here. This is unwanted when projects are shared between users/machines. For example, I w...

This could also work. Double check that you can switch the settings on-the-fly and that the re-config works in time. hthKnarfB

The GPIO IDR register of a PWM pin should hold the current pin level, even if the pin is configured to alternate function mode for the timer. So, if your handler is fast enough, you can query IDR whether the first capture hit a rising or a falling ed...

Did you enable RTC before setting RTC Mux?hthKnarfB

If you capture on both edges, the timer may hit a rising or a falling edge first what explains your observations. If timing is not too fast, you may query the signal level in the interrupt handler and adjust your interpretation of the time stamps acc...

Thanks.The startup files like startup_stm32c011f6ux.s are still broken. The g_pfnVectors handler order looks better now, but all reserved entries are still missing as in STM32 VS Code Extension generates startup file wit... - STMicroelectronics Commu...
