Posted on February 28, 2016 at 17:43Hello,I have a problem with CAN bus on STM32F103TB.I have CAN_ESR register = 0 but still I get bit ERRI in CAN_MSR = 1.If i try clearing it either via code or via debugger it will be set again by hardware.I've sea...
Posted on April 08, 2016 at 15:37Hi i wonder if there is a way to transfer from pheripheral to pheripheral using dma on f429.could anyone tell me ?
Posted on April 08, 2016 at 21:21Hello.I would like to get a size of a struct in bytes. Members of a struct are different - concretely I have 6 WORDS and 1 array of 6 BYTES. Then, the size of a struct would be 30 BYTES. If I use function sizeof(stru...
Posted on April 09, 2016 at 12:42Hi all,I'm experiencing a strange problem on STM32F405When a IWDG reset happens, the uC restarts with a wrong clock frequency, I think it's running from HSI instead of HSE. Same problem happens even if I call NVIC_S...
Posted on April 08, 2016 at 22:55Hello,I got a stm32L152C-discovery kit and would like to know how do I measure the actual consumption of stm32l152 microcontroller?I analyzed the board and saw solution to measure stm32l152 of current consumption.Tha...
Posted on April 08, 2016 at 23:55Can I, used SWD pin, for example on STM32F0, as SWD when debugging and flashing MCU and as little used IO , during normaloperation? If yes, how?
Posted on April 06, 2016 at 19:02I encountered this problem while trying to run the demonstration firmware under the debugger. I am running the Demonstration firmware on the NUCLEO-F411RE board with the Adafruit 1.8'' TFT Shield attached. I have two...
Posted on April 08, 2016 at 15:11Hello,while writing a bootloader, I had the need for a few bytes (4) that retain the content during a software reset. I�ve read that is true for the first bytes of the SRAM. So I�ve added a new section at the beginni...
Posted on April 08, 2016 at 09:51On the STM32F303 I have a timer with an OC that triggers DMA events to write byte values onto GPIO. The DMA is set up with a cyclical byte buffer that is populated by the core via interrupt. For technical reasons I n...
Posted on January 08, 2014 at 14:30Hi Everybody,I am using the RTC WakeUp Timer while in Stop mode. The MCU can either leave the Stop mode at the end of the timer, or on an external IRQ. At this level, everything is working perfectly.However, when t...
