Posted on June 21, 2018 at 18:31I try to use the Analog Window Watchdog of a STM32F030F4. For starting I wanted to keep it as simple as possible therefore I started with a single channel conversion in continous mode. The window when an interrupt sho...
Posted on June 18, 2018 at 23:06 I'm trying to get an interrupt-driven CAN receiver working on a STM32F042K6- but I'm not having much luck. I'veconfigured the CAN module in CubeMX and the code it generates makes sense to me - and seems to match t...
Posted on June 21, 2018 at 10:56I am running STM32F303VC.I require an IRQ on GPIOE_Pin_15 ---> TIM2_Channel_1My typical Frequency range is from 5 Hz - 500HzThis is required to provide me with a number of ticks between the 2 interrupts. The result ...
Posted on June 21, 2018 at 00:57Hi,I am working on STM32 flash program using a sample program from V1.11. The program is pretty straight forward. Erase ADDR_FLASH_PAGE_16 to ADDR_FLASH_PAGE_255 then program.The program stuck in HardFault_Handler doi...
Posted on June 20, 2018 at 23:24I am trying to initialize GPIO ports on STM32F103C8 using the LL library. When I set up pin PC13 by a sequence of individual calls (LL_GPIO_SetPinMode, LL_GPIO_SetPinOutputType), it is initialized correctly. However, ...
Posted on June 21, 2018 at 20:35Hi,With the cubeMx tool, when i use usart2 , the lpuart can not be included.But when i set as bellow, is it possible to use usart2 tx/rx full duplex, and lpuart tx only ?-- as follows--Usart2TX : PA2RX: PA15LPUARTTX :...
Posted on June 20, 2018 at 13:08What is the best way to find the execution time of a particular section of code in the STM32 microcontroller? Except checking on DSO.Majerle.Tilen.001‌null
Posted on June 20, 2018 at 13:46As i had lack of speed while using stm32f407 disco, i ordered stmf746 nucleo-144. And What suprised me was that it is slower then stmf407, despite that stm32f07 168 max mhz, and stmf756 is up to 216Mhz. I configured m...
Posted on June 21, 2018 at 11:33CubeMX doesn't like a frequency of 12 MHz for HCLK with the STM32L433CC.HCLK is suggested to be at least 14.2 MHz, but I couldn't find any such requirement in the reference manual or datasheet.The F4 RM0090 mentions: ...
Posted on December 23, 2017 at 23:31I'm trying and failing to get printf debug to output via SWO on a H743ZI-based Nucleo board. I've added retarget_io.c for STDOUT via ITM Port 0 in my Keil MDK v5.24a based project. I have the ST-LINK/V2 debugger f...
