Hi, I have my PCB that have a processor used as host and STM32U5 (STM32U585AII6Q) used as low power MCU. USART connection is between host and STM32U5.When I enter Stop3 low power mode, and host is turned off, there is a problem with current on USART ...
Does the STM32U5 series support PD3.1 standard: in hardware?in ST-provided firmware?If not, is there any future upgrade planned to make it support PD3.1?
Hello,I've been unable to determine if it's possible to use the DMA to write data from internal RAM to internal flash on an STM32U585 device.I've consulted the following, but don't see a clear answer:https://www.st.com/resource/en/application_note/an...
Hello, I'm trying to implement the temperature sensor TSYS01 on STM32U575I-EV.The datasheet of the sensor tells to reset the sensor first so I'm trying to do this like this:HAL_I2C_Master_Transmit(&hi2c2, 0x77 << 1, 0x1E, 1, HAL_MAX_DELAY);0x77 << 1 ...
I am trying to evaluate the FDCAN function on a STM32U5 and somehow I don't manage to make it work .I can receive a frame when I am in (external) loop back mode and if the FDCAN transmits the frame but I cannot receive a frame in normal mode from an ...
Hi Team,I have configured the I2C in Master Mode and Enabled LPDMA channel 2 and 3 respectively for I2C3Tx and I2C3Rx./* I2C3 DMA Init */ /* LPDMA1_REQUEST_I2C3_TX Init */ handle_LPDMA1_Channel2.Instance = LPDMA1_Channel2; handle_LPDMA1_Channel2.I...
I am looking for maximum timer resolution supported in STM32U5 series MCU's.Basically whether I can configure or use hardware timer as 100us.Any input or documentation on this would be a great help.Thanks!!
ContextI am working on NUCLEO-U575ZI-Q with an external ADC wired to the board. The ADC generated a rising edge on one of its pins, "DRDY" each time a sample is available.My objective is to retrieve the ADC sample without involving the CPU. The curre...
Hello!I'm trying to communicate between two B-U585I-IOT02A boards through Wi-Fi. I just want to be able to send a simple hello world message to one board from the other. My current thought is to set up a simple Wi-Fi network with one board as an acce...
As soon as i configure PB4 as SPI1_MISO, I get disconnected from the target. Even the connection doesn't use the NJTRST pin.It used to be a bug on the stm32L4, but I could't find it mention on the errata of the stm32U585.Has anyone (ST) knowledge abo...
