I am facing a strange issue that looks like a possible microcontroller design/behavior problem.My setup:I need the DAC output pin to provide a stable voltage while the microcontroller is in STOP2 sleep mode with the RTC running.Power connections: Vb...
I'm try to generate some pulses to PB0 using STM32F103C8T6 with the following code#include <stdint.h> // STM32F103C8 is a medium density device, hence we use the xB header #include <stm32f103xb.h> #if !defined(__SOFT_FP__) && defined(__ARM_FP) #warn...
Hello, I am currently trying to measure the temperature using the internal temperature sensor of STM32F765. The Reference Manual stated to do temp = ((V_sense - V_25) / Avg_Slope) + 25,but the address of calibration data existed in the Datasheet.In t...
Hi all,we are designing a product based on a STM32U083. The device is battery powered (not removable) and it can remain in storage for at least 2 years. To reduce battery drain we are putting the mcu in shutdown mode to then wake him up via a button ...
Hi, I am working on a project with the STM32H730. In order to make full use of the onboard memory I have the project set up to load some objects into DTCMRAM. This works, however the binary size is huge, like 403 MB, and subsequently is crashing cube...
This is a very basic question.I built a custom board using the STM32L433.After applying power (+3.3V), I checked the NRST pin state, but it did not reach the default voltage.Could you please tell me any possible causes?For reference, I have confirmed...
Hi,Master:MCU: STM32H743IIQuestion:I configure the MPU for RAM as follows:mpu_set_protection( 0x24000000, MPU_REGION_SIZE_512KB, MPU_REGION_NUMBER1, MPU_REGIO...
Hi,I have been trying to connect PSRAM and NOR FLASH to STM32H563 nucleo board using Dual-Quad-SPI.I was able to successfully read/write to PSRAM and NOR Flash individually in single-Quad-SPI mode with base address 0x90000000. i'm not clear how the a...
Hello,On a custom-designed PCB, I am using an STM32H745IIT6 (LQFP176) MCU. I am actively using analog channels, various I/O pins, Ethernet, QSPI, and other peripherals. The code I am using was previously running on an F7 series MCU. It has been fully...
I am using the STM32H753VI chip, it's on a proprietary PCB but the layout is very similar to the nearest NUCLEO board so I am not ready to consider that the issue.I am working on a very low power application, using CubeIDE but minimal HAL, preferring...
