Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi,I want to kick ADC1 IN5 with the Timer TIM2. I'm working with CubeIDE.I select:ADC1 -> ADC_Regular_Conversion_Mode -> External Trigger Conversion Source -> Timer 2 Trigger Out eventTIM2 -> Trigger Output (TRGO) Parameters -> Update EventBut ADC1...
ST‑LINK Mini V3E not detecting STM32H7 (Core ID error, high current when VTARGET connected)I’m debugging an issue with a custom STM32H7 board and an ST‑LINK Mini V3E. The setup includes a main PCB and a separate power PCB. So far:Power & Basic Checks...
I am using the ST Host library version 3.54 on an STM32F769 device, supporting HID devices. I am using the internal Full Speed phys.I have a USB mouse connected and all works fine, however I would like to save power when the mouse is not being used ...
Hi,I’m working with a custom PCB based on an STM32H743BI and an external MT25TL01G memory device.To manage the data I’m using FileX + LevelX. I’m able to create the media, create directories, create files, write to them, and read them without issues....
Hi everyone,I'm working with an STM32F401CCU6 and trying to transmit 2 bytes over I2C3 using DMA1 Stream 5 Channel 6, which is the correct mapping according to RM0368 Table 28:DMA1 Channel 6 Stream 5 -> I2C3_TXThe DMA configuration appears correct, a...
Hello,I have a issue with my STM32U5G9. It does not go into standby or shutdown mode. I want to achieve a wake-up by the power button of my device. The powerbutton is connected to PWR_WKUP6 (pin PB5). The button has a 100k pull-up. I verified the vol...
I have a dual core application running on an STM32H7 where I would like: the CM7 to tell the CM4 to enter stop modehave the CM4 enter stop modeat a later time, have the CM7 wake the CM4 from said stop modeIn the CM4 code, I'm doing this: HAL_PWRE...
When using the STM32H743ZI Nucleo board as the I²C master and two STM32 Blue Pill boards as I²C slaves with different addresses, the master requests data from the slaves and the slaves respond accordingly. However, I²C communication is unreliable d...
I am using the STM32U585RIT6 microcontroller with the B-U585I-IOT02A development kit. I need to implement USB functionality using an interrupt-based approach. In my project, I have configured USB_OTG_FS in Device-only mode, enabled the NVIC global in...
