Hi all, I'm trying to test STEVAL-IDB008V2 board with wise studio and BLE_SensorDemo project I can compile and flash with RF-Flasher.So for now I'd like to add my own service, the basic example privde 2 services - Acc service- Env serviceI'm trying t...
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 don't use the internal Step Down regulator. How should the pins be tied?Should VDDSMPS be tied to VDD and VSSSMPS to GND with VLXSMPS and VFBSMPS left open?OR - should they ALL be left open?Documentation only speaks as if they are to be used - no c...
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...
