Recovering from hardfault - HardFault_Handler

Hi, my mcu in locked on HardFault_Handler.Even if I reupload a different firmware.Did I broke it ???

hi iam trying to interface stm32f4 discovery board with ADC IC ADS8320. the maximum spi clock that can be given to ADC IC is 2.4MHz. But when i try to reduce SPI clock frequency to 1MHZ(using the external cystal given in board as clock source.)

the uart stops working and code gets stuck. Can anyone tell me why this is happening?

Does the STM32F722IE FMC block support multiplexed, 32-bit data width SRAM-like interface?

I have an application that requires a high speed interconnect between a large FPGA and STM32F7 microcontroller. We chose to use the FMC block for memory mapped access into our FPGA. Does the FMC block in the STM32F7 support 32-bit data width with mul...

STM32H7 DAC sinewave generate using formular

I'm success create sinewave signal by using table:uint32_t Wave_LUT[NS] = { 2048, 2149, 2250, 2350, 2450, 2549, 2646, 2742, 2837, 2929, 3020, 3108, 3193, 3275, 3355, 3431, 3504, 3574, 3639, 3701, 3759, 3812, 3861, 3906, 3946, 3982, 4013, 4039...

STM32H745 does not generate SPI clock signal when it is set to 60 Mhz ?

Hello,I have a 250 Mhz oscilloscope. I am analyzing SPI clock signals at different speeds. Once I tried to have a maximum clock speed for SPIs in H745, I cant see anything from the clock pins. When I set the prescaler to 4(30Mhz) or 8(15Mhz) I can s...

Resolved! Problem with outputting LSE clock on PA8 pin as MCO

Hi!I'm trying to output the LSE clock on the PA8 pin on my Nucleo64 STM32L476 board.The code I have written is the following:#include<stdint.h> #define RCC_BASE_ADDR 0x40021000UL #define RCC_CFGR_REG_OFFSET 0x08UL #define RC...

Resolved! How to generate hex file in STM32H750vb?

I am trying to generate hex file for my boot loader. I need a fix length hex file for my boot loader. I tried arm-none-eabi-objcopy -O srec --srec-len 0x10 ${ProjName}.elf ${ProjName}.srec;arm-none-eabi-objcopy -I srec -O ihex ${ProjName}.srec ${Proj...

Does the RTC run when Vdd = 0 but Vbat = 3 volt?

I have a STM32F373VBTx serie. I know that the RTC saves the backup registers for every second. But when I restart my STM32, then the RTC sets to default date and time again due to the MX_RTC_INIT() function who is generated by CubeMX.I have two quest...

Will DMA restart in circular mode clear previous unfinished array(STM32G491CE)?

HiOur chipset is STM32G491CE.I use DAC with DMA in circular mode. DAC stop and restart. It is started previous array index.I want to be clear DMA circular buffer index.How can i do it?
