Resolved! assignment discards volatile qualifier problem
I have a SPI Receive Interrupt function. where I have use *pRxBuffer as a volatile. But, I get the error of "assignment discards volatile qualifier". As attached in the figure below. How do I fix that line to make sure the warning will go away?
STM32 Timer?
I'm just getting started with STM32, so I'll askI need to generate a 25ns pulse 75ns gap on one output and againOn the other the same, but shifted by 180 degrees, ie by 50nsIs it in the power of STM32 timers to do this?The whole is mainly the rising ...
Issue with memory placement in Cube IDE generated project for STM32H755
Hi all, I have a Cube IDE project generated for the STM32H755 Nucleo using Cube MX. I switched out the linker script for one that I have used in other projects with this board, basically just defining some sections for large buffers in RAM. I use the...
What would cause the RTC to become damaged or stop updating hrs, mins and secs (but not subseconds) on an STM32L082 within a Murata CMWX1ZZABZ-078?
I have two projects, both using HAL libraries in STM32CubeIDE 1.5.1.The first project simply initializes the RTC, using external 32kHz crystal, and then falls into a loop that reads the RTC every second. Using my debugger with a breakpoint, I can see...
External OctoSPI flash and internal Flash
Hello everyone ; I am sorry for the basic question ; this is my first experience in external flash. we a re using kiel for develop our software . how can I set that some part of code to be located in the external falash ? and is it possibel to have m...
How can I prevent shared ISR from triggering the opposite core?
Hello,I have a dual core project on an STM32H745. Timer 8 is used by the CM7, Timer 13 is used by the CM4. Timer 8 and Timer 13 share an IRQ, "TIM8_UP_TIM13_IRQHandler".I've double checked the setup and:CM7 RCC_C1_APB2ENR has TIM8 set and RCC_C1_APB1...
VREF+ current consumption
HiI use 16-bit ADC of STM32H725 with an external 3v reference.what is the current consumption from the Vref?in the datasheet DS13311 - Resources - Search STMicrocontrollerstable 83 the current consumption is only from VDDA.
Resolved! BOOT0 pin and SWCLK pin are the same pin - Is that OK?
Hi!I'm using STM32G030F6P6 TSSOP-20 and I notice that BOOT0 pin and SWCLK pin are the same pin. If I want to program the STM32G030F6P6 MCU, then I only need SWDIO and SWCLK and NRST pin and forget about the BOOT0 pin because BOOT0 pin is not avaiable...
