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...
Posted on February 08, 2016 at 21:56 Hi, I'm using a STM32F429 disco board. I used the CubeMX to gen my HAL. Everything works pretty great, except for after a while my CAN IT stops firing. Here is my code below. In the HAL_CAN_RxCp...
Posted on April 07, 2016 at 12:13Is it possible to assign the priority to Timer channels.I am suing timer1 channels 1,2,3,4 where time period of channel 1,3 and 2 and 4 are multiple of each other so thier respective interrupts comes at the same time...
Posted on November 23, 2015 at 15:16 Hello every One I am trying to read PWM signal parameters (Frequency & Duty Cycle) with timer 2 of STM32f4 IC. According to data sheet There is two modes of reading PWM signal. 1- capture mode which reads Puls...
