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...

Don't know about TotalPhase, but a $10 logic analyzer could show the signals on the wire.In CR2, FRXTH bit must be set when using 8-bit transfers.DR register is 16-bit wide. When reading/writing 8-bit values DR register must be type-casted: *(__IO ui...

there is nothing wrong. Your Release config doesn't generate debug information for source level debugging so you are stuck at assembly level. There are options to combine release type code optimization and including some minimal debug info. The detai...

HAL_Delay would work here if you set the priority of the timer interrupt lower than SysTick. As @waclawek.jan pointed out, spending long time in an interrupt handler is often considered bad style. Alternatives, besides the already suggested shifting ...

For that, use double-buffer mode. Not available in all series/MCUs but at least in (most?) H7, see RM0455 Reference manual.Covered in stm32h7xx_hal_dma_ex.h HAL_DMAEx_MultiBufferStart_IT, HAL_DMAEx_ChangeMemory.hthKnarfB
