Hi I am working on a own prototype.The issue facing is NRST pin pulled low once powered on.Actually it should give me 2V.MCU used is STM32G030K8.and also on checking the PCB tracking its fine .When we checked by removing the MCU chip NRST is 2.0v .Wh...
I am trying to test QuadSPI peripheral in the STM32H745BIT6 by carrying out an internal Loopback test. I am apparently not configuring its parameters correctly. Can anyone suggest what configurations I should do for QuadSPI and if there's anything wr...
I'm using CubeIDE and I have PG10 configured as MCO output and I see nothing. Usually when I see this, there is a HAL enable command I missed, but I don't think there is in this case. I've tried multiple clock sources and the pin stays at voltage hi...
Hello,I have a problem, I would like to change a timer output compare mode on my STM32G484xE microcontroller. I would like to switch between toggle and PWM mode 1. I do the whole thing with a small function for writing registers:void ProgRegister(uin...
Hi, I want to write into flash on an STM32WB15 mcu. I have this code, where i write two 32 bit variable into the flash. void Write_Flash_Data(uint32_t new_value1, uint32_t new_value2) { HAL_StatusTypeDef status; HAL_FLASH_Unlock(); // Unlo...
hello: I use NUCLEO-H7A3ZI-Q to implement a bootloader feature:the bootloader runs in 0x08000000 at flash, it'll copy the application stored in 0x08005000 to 0x24000000 in RAM, then jump to 0x24000000, if one LED turns on, indicates jumping to ap...
Hello everyone,I'm currently working with the STM32G474RE MCU and using a CANopen stack. I'm facing an issue where the Auto Bus-Off recovery isn't happening as expected.When there's a fault on the CAN bus, it correctly transitions to the warning stat...
My MCU is the STM32H723. To save GPIO pins, I would like to use the following architecture:- Connect external HyperRAM and Flash to one OCTOSPI bus. - Use multiplexed mode to access OCTOSPIM_P1 and OCTOSPIM_P2.- Map external RAM and Flash to differen...
Hi, i start design on G4 and am confused with internal ref in MX.1. Internal REF for ADC isnt real internal, but Vref2.Internal ref for comparators is 1/2 1/4 3/4 ... , but from what ?3. ADC stop working without VREF+ pin voltage, but comparator work...
Hello,I am trying to implement the following: a timer (tim3) is set to PWM generation, outputting a pulse periodically. Its TRGO triggers the DMA channel to request I2C to initiate a read transaction, read 8 bytes and generate an event interrupt (TC ...
