Hello,I have a question regarding the external interrupt on a GPIO input pint which is triggered each falling edge (EXTI)According to the CubeMX autogenerated code, it looks straight forward. I am using a discovery board with pin PE3 which is config...

Hello,I would like to use ADC with a group of several channels (ScanMode = Enabled) along with the DMA. However, I would like to avoid to use the DMA in circular buffer mode. I have seen so far that most of the examples and external literatures are b...

Hello,I have one question regarding the ADC1/2/3 cores for the STM32H7 (dual core solution). Let's say, I would like to split few ADC channels between both ADC cores and Cortex cores. Is it possible to assin channels 1,2,3 for ADC1 core (regular grou...

Hello, is there any documentation regarding the startup on both cores as I see there are several possibilitiess to gate the other core or to let them run directly in parallel. Nevertheless, CubeMx generates a common startup file which is shared I ass...

Hello,I have few questions regarding the TIMER capabilities confgured as input capture. According to the reference manual, the direct input capture of TIMxCH1 in conjunction with a TMxCH2 which is configured as "indirect input capture mode" along ...

Hello, thanks for your feedback. Are you refering to an external pulldown resistor which is attached to the corresponding input pin or do you mean to enable the internal pulldown mode of the input pin. I already tried the last approach. Unfortunately...

Hello Pavel,i tried it on both cores but always assuming that the initaliaztion and its usage is performed by only one core. Either on the CM7 or the CM4 is not runningI created a new project based on CubeMx. There re also several tutorials for diffe...

Hello @Community member , thanks for your feedback. So when I use one timer which contains 4 channel with direct and indirect capture mode capabilities, which are used as pairs, lets assume Channel 1 (direct mode) + Channel 2 (indirect mode) and Ch...

Hello TDK, thanks for your reply. I know about this embedded feature. This question was referring more from an initialization point of view as it looks, at least for me, a bit venturesome, when one core could directly read/modify/write to an GPIO out...

Thanks for your reply. What does that mean for the initialization of common peripherals. Imagine one core initializes one peripheral e.g. SPI, GPIO. After some time the other core does an inititalization as well but it changes one GPIO from input to ...
