Hi all,I have the following problem: the backup domain registers are sometimes cleared on power off/on, despite having a 3V coin cell CR1632 connected to the pin VBAT and the GND plane. The RTC registers are then cleared. The error occurs sporadic. T...
Hello everyone, I would like to know if the Nucleo-H7A3ZI-Q supports the MDIO to external Ethernet PHY control via SMI (MDC and MDIO). I have the setup connected, and I have programmed it accordingly but the MDC and MDIO Lines are always LOW, not eve...
HAL_GetTick() returns the value -128 when called in I2C write memory bite Here are the code snipets how to resolve this error
I am trying to use STM32H7R7L8H6H working on design. So in our design we uses multiple interfaces like TFT LCD, Ethernet(RMII), RS485, Wi-Fi-BLE module. So For MCU power supply mode selection between LDO and SMPS. Which one mode ST will recommended t...
I would like to use TIM2 as a performance counter to evaluate my software changes. Is the TIM2 internal clock 1/4 of the CPU clock on the NUCLEO-G0B1RE board? Net effect, resulting in the TIM2 counter having a resolution of four CPU clock cycles.Than...
Hello. I don't know exactly what the IDE needs, but it doesn't seem to see the St link server, but at the same time says that it is installed. When you press the Debug or Run button, a window appears with the inscription "ST-Link Server is required t...
Greetings,I'm developing an RTOS app the should use QUIC protocol for communication.There is ngtcp2 project and wolfSSL is available in STM32CubeIDE Device Configuration Tool as ngtcp2 supports many SSL libraries.For this I need some network communic...
Schematic 1. Most documents refer to add a PU on UART TX (target side), why is there a PU on UART RX and not TX, but there is a PU on VUART TX and not on VUART RX ? Seems inconsistent.2. For consistency or guideline, should the UART PU be on the boa...
Hi everyone,I'm working on a project with the STM32 Nucleo L432KC, where I need the microcontroller to enter shutdown mode to save power. The board is connected to an external RTC that triggers an interrupt every 30 seconds to wake the microcontrolle...
Hello,I have a evaluation board STM32L552E-EVAL and I would like the know how to connect the JLINK (EDU) to this board ? According to the instructions I see this connector which could possibly connect with the JLINKThank you for your helps.
