Resolved! STM32CubeIDE 1.13.2 not showing X-Cube-Mems1
Hi All,I have configured for STM32L071xx xx controller bare metal. I was not able to find X-Cube-Mems1 for the controller.Please me know if LIS2MDL (or Mems package) is not supported on STM32L0 series?PFA screen shot of the STM32Cube IdeThanks,Milind
Resolved! RTC clcok slow when turning on LTDC
Hi,I am using a custom board to do some application (https://www.waveshare.com/openh743i-c-package-b.htm). On this application I should turn on LTDC (to use it with touchgfx) and I am also using the RTC.When I am only using RTC alone, the RTC clock i...
Resolved! CORDIC for phase(atan2) not much faster than math.h atan2
I have two functions to calculate the phase via DFT. In both functions, real and imaginary parts are first calculated, and then the phase is determined using different methods.The first function employs the standard atan2f function from the math.h to...
Resolved! flags to use to enable FPU on STM32H5 MCUs
In this document it's stated that STM32H5 devices implements the FPv5 floating-point extensions.From there, how do I know the proper flags to pass to gcc to enable the FPU? -mfpu=fpv5-sp-d16 -mfpu=fpv5-d16other ?
STM32F334C8T6,main program is stuck
I wrote an interrupt service function HRTIM1_TIMA_IRQHandler() for PID tuning at a frequency of 200kHZ. Is this frequency selection reasonable, after I enabled this IRQHandler, the main program in main.c no longer works, what is the reason?
RTC Not Running
Hi, I had configured the clock to LSI RC 37KHz using cubemx with AsynchPrediv is 124 and synchPredivdivider is 295 after the RTC initialisation i'm trying to read the time using HAL_RTC_GetTime() but i'm getting the values what i initialised but d...
Resolved! Reading temperature from adc value(Non linear)
Hi,I am using STM32G491RE. I have to read temperature values from ADC. We used voltage divider circuit to map the voltage values with temperature values it is non linear change between volatge and temperature.I tried below wayconst uint16_t adc_valu...
Why does the download fail after changing the code in Keil?

Resolved! STM32H735G-DK OCTOSPI2 HyperRAM 1st Read PASS, next Read FAIL
Hello, I created the STM32H735G-DK project with the board selector in STM32CubeIDE. The OSPI_HyperRAM_MemoryMapped project was created by the example selector. Its HyperRAM test codes were added to the STM32H735G-DK project as below. The reading se...
