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...

According to RM0394 Rev 4, TIM15 has 2 channels, but only the first is present in the .svd file and hence the debug view, see attached picture.Observed for STM32L432KC using STM32CubeIDE 1.9.0, (com.st.stm32cube.ide.mcu.productdb.debug_2.0.200.202201...

Hi, I have 10 DK2's in a server rack for development and testing. STM32CubeIDE (1.5.0) debugging wants me to specify a serial port and an IP address for debugging. This is IMHO redundant, why? Moreover, the serial ports /dev/ttyACM* are to be selecte...

Don't have (your) hardware at hand, but my code used to work flawlessly: https://gitlab.com/stm32mcu/i2c_master_and_servanththKnarfB

I won't go through all your code, but there is no hardware feature that significantly delays CCRx register updates even without DMA. Check all your calculations and/or add debug output.I would set the prescaler such that the timer increments per micr...

I used I2C_NEXT_FRAME, not I2C_FIRST_AND_NEXT_FRAME. The UM1940 - Rev 3 user manual says something about flag usage. I also used sending single bytes only (not 6) to keep fine grained control over what's happening on the bus. But is may (shall?) work...

Anyway. Note, that to divide a timer clock by x, you have to set ARR to x-1, not x. This might have caused the error you have observed.hthKnarfB
