using Dual-Quad-SPI with OCTOSPI in STM32H5xx
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...
STM32H745 ADC - PA0 Sampling Issue
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...
Resolved! STM32H753 STOP Mode inconsistency.
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...
STM32U575QII Dedicated OPAMP2_VINM pin not connected?
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...
Not able to enable SYSTICK
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...
STM32F767 ADC value significantly larger than expected
We're using the ADC function built into the STM32F767.The problem is that when the analog signal input to the ADC is around 200mV, the digital value output from the ADC appears to be around 240-260. We're trying to obtain a stable value by collecting...
How to switch between sleep modes in STM32L476RE?
Hi Team, I am planning to use STM32L476RE MCU for my project, Can I know how to switch between Stop1,2 and low power sleep and run modes? I am new to STM32 and I need a reference code or some guidance to start with, any help very much appreciated. Th...
Resolved! STM32F413: Use all 3 CAN interfaces simultaneously, but independently?
We are developing a product that needs the ability to run 3 separate CAN interfaces connected to 3 separate CAN buses. I have the NUCLEO-F413ZH and I can successfully initialize and start CAN1, CAN2, and CAN3 and transmit from each of them in a sing...
Resolved! STM32N6 DK stuck when generate default project
Hi,Im just getting my new STM32N6570-DK and I try blinking simple led project first with default generate.But when I built and flash it, it got stuck when init UCPD (pic 1), am I missing something ?When I checking seem it still not define yet (pic 2)...
