I have a board in which one STM32 (call it "central") is required to update the firmware on a number of others ("sensing"). It seems simplest to use the USART1 interface for the built-in bootloader on the sensing processors. I would like to multiplex...
I am trying to change the system clock on my STM32F412 discovery board to 100 MHz using the HSI, however it just seems to crash. I am using direct writes to registers, but I looked at pregenerated CubeMX code and my registers look the same for the cl...
HiI am developing a product using stm32f429.case 1>- use cmsis_rtos2- Interrupt is generated every 20ms using exti1(PA1).- In exti1 callback function, execute gpio is set > delay 1ms > reset.case 2 >- case1 + fmc initialize codecase 1 works fine. H...
This issue i used get always even at R&D or bulk production too. It's keep on coming. Please any one help me out the exact reason. Thanks in advance.
EDIT: For crying out loud. Why is half of my code chopped off? #if !defined(__SOFT_FP__) && defined(__ARM_FP) #warning "FPU is not initialized, but the project is compiling for an FPU. Please initialize the FPU before use." #endif #include "stm32...
Dear friends,I am using STM32f407vgt6 and a DS3231 RTC module and I use I2C1 peripheral to read date from DS3231. It is working fine but after 10 or 12 minutes the I2C bus is continously BUSY and I do not know what to do.Is there any way to control t...
I think that the macro's__HAL_TIM_GET_UIFCPYand__HAL_TIM_SET_COUNTERuse the predefined __COUNTER__ as an argument, while not meaning to do so. At least for the gcc compiler.now i can't use __COUNTER__ myself .... :)Am i correct?
Hi,i am desperately trying to start multiple Timers with the HRTIM as single trigger.The datasheet states, that internal trigger connection "tim_itr10" is "hrtim_out_sync2".So I enable the HRTIM-Master-TimerHRTIM1->sMasterRegs.MPER = 0xFFDF; HRTIM1->...
Hi all,I'm attempting to run the simplest example code provided for the STM32H745XI dual core (M7 and M4 cores). I've configured my cube debugger as explained in the link below, and I'm having no success debugging or even starting the second core (M4...
I'm working with the STM32H7 MCU and I have three memories (1 flash, and 2 fram) connected to SDPI1 interface. According to flash datasheet, max SPI clock can be up to 80MHz. Nevertheless, when having the SPI SCK set at 7.5MHz (SPI peripheral clock i...
