Hello, I am trying to write some non-blocking motor driver code for a STM32F401Re board. Currently, I am setting the timers to PWM mode and adjusting the ARR to change the PWM frequency using an IRQ handler. This approach is working for TIM3 output, ...
Hi,I'm currently debugging what I think to be a code issue. I have a custom board with all peripherals physically disconnected and a NUCLEO-U575ZI-Q dev kit. The lowest current I see is about 250uA on both setups, with a sawtooth charge/discharge wav...
Hello everyone,I'm facing a HardFault issue when jumping from a bootloader to an application on the STM32L476RG.The fault occurs right at the beginning of the application, specifically at the instruction bl __libc_init_array inside the Reset_Handler ...
Hi all,currently iam using the stm32h757 controller.i want to use the FMC on both cores, in SRAM mode with this config: hsram1.Instance = FMC_NORSRAM_DEVICE; hsram1.Extended = FMC_NORSRAM_EXTENDED_DEVICE; /* hsram1.Init */ hsram1.Init.NSBank =...
Board: stm32h753zi nucleoFirmware & CubeMX: latest versionI have configured the adc to continous conversion and DMA output. The initialization fails in main.c in HAL_ADC_INIT. I stepped through the HAL lib and saw that LL_ADC_IsInternalRegulatorEnabl...
im using STM32H753VIT6 MCU.I'm try to connect device using SWD in STLINK debugger but it will show "Error: Unable to get core ID" this Msgim checked MCU input voltage,im getting 3.3v .input power is oknow how can i debug this issue.SWD pins properly ...
STM32L071CBT6 GPIO PB15 Input Not Responding to 5V Signal from Buck ConverterHello everyone,I'm using the STM32L071CBT6 microcontroller and facing an issue with reading a digital input on GPIO pin PB15.What I'm Trying to Do:I’m using a buck converte...
Hi, I was trying to test the feature of "Level 2 flash lock" on my custom board. I'm having an unexpected behaviour.My total application consists of a bootloader responsable to load an application via CAN BUS through a custom communication protocol.N...
Hello,I read the UID from STM32L031K6P6 and each device returns the same result: 0x14473332, 0x38363437, 0x0.I read the value from the address given in RM0377 (0x1FF8 0050).Is the address given in RM0377 correct?I am attaching screen shots from CubeP...
I use the STM32CubeIDE platform and I need to insert into my project a routine that was able to update my firmware.What I need to understand is:I write the routine then I place it into the ITCMRAM and I run it; does it work ?Have I only to load into ...
