Hello,I use Idle Line interrupt as a timeout for UART Receive, to end up an ongoing receive process.All in all, it works good for me, but I do have a constant issue on all the STM32, like L1, L4, H7, with a "fake interrupt upon reset". That means :...
Hello,I'm currently working on a UART communication between the mentioned STM32 microcontrollers and would like to use DMA. But I'm a bit concerned about memory consistency. I already read a lot about this issue and tried to find any information, how...
Hi, I am using STM32F413ZH Discovery Board and trying to reset MCU from the WatchDog timer. So I found there are two WatchDog timer in FreeRTOS IWDG and WWDG. and one example I created with toggling the LED in that I enabled the WWDG timer. after tog...
Hi,I'm using the STM32F303 and CubeMX with low layer.I try to read two ADC-values with the injected conversion. In CubeMX i defined two ranks to read the values from the ADC. For rank 1 everything works fine and in the JSQ1 register contains the righ...
Note: when i use the CubeMX and configure the pins for USB cdc and the UART1/2 show warning conflict
Hello,We need to use analog front-end providing a 1-bit Delta-Sigma interface (clock output + I channel and Q channel) with STM32F411 or STM32F412, initially we planned to use the STM32F411 but i noticed that the STM32F412 has a DFSDM peripheral wh...
Hello,I've got a realy strange issue. I'm using an STM32F107, with SW4STM32 and CubeMX. The controller is on a custom board. When I click on "Run" in eclipse, the controller is not starting. It seemed, that he's going immediately in a HardFault. Even...
