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?
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 ...
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...
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...
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...
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...
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.
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...
* I am using STM32F042G6,*I need examle for CAN Bus both TX & Rx,*Receive mode of (Interrupt)*i am using cube ide:4.24.0
When acting as I2S master, the kernel clock frequency for SAI or SPI must be set to some multiple of the audio sample rate, and the bit clock and frame sync signals are then generated by dividing the kernel clock. Now, if acting as I2S slave the bit ...
