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...
Hi,I’ve been struggling to get an image from an image sensor using DCMI via GPDMA on an STM32U595.The sensor outputs a 1280x800 image in 12-bit RGGB Bayer format, which I’ve configured correctly. That gives 12 bits per pixel, and I want to capture th...
I have a project which uses both OPAMPs. For both OA I use dedicated VINM pin.OPAMP1 works correctly.OPAMP2 behaves like the dedicated pin (M2 ball) is not connected to the input multiplexer.I 've tried - mode FOLLOWER: OK - mode STANDALONE, reconnec...
Hi,I am working with the STM32F103RCT6. I am writing a bare metal code for delay function using SYSTICK timer. The problem I am facing is that I am not able to write to the ARM cortex registers. Below is my code for your reference - This is the stm32...
