STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi, I am using STM32H563 Nucleo board, and found the PLL1VCOSEL bit of RCC PLL clock source selection register.There are duplicates in the settings.Does anyone know why is the settings duplicates?I would like to know why and use case.
We have designed a boards, main board has STM32H742VGT6 and it is connected to Microchip PHY IC KSZ8091RNBCA in RMII Mode, Onboard Clock 25Mhz for PHY) we have tried basic configuration such as enabled ETH, LWIP Stack.we are using STM32CubeIDE 1.13...
The attached code configures UART communication to wake up a microcontroller in sleep mode as soon as a frame is received. In sleep mode, the micro waits for data on the UART interface, and when a UART frame is detected, it automatically wakes up t...
I have an External Loader Project made for STM32G0/G4/L4.I ported it to STM32U5: all the functions work fine when debugged from STM32CubeIDE (so the connections are ok). With the STM32CubeProgrammer the .stldr file is recognized but the Read/Write/Se...
Hello all, I'm new to STM32, I have been given a project to display the time and date on either an 16x2 lcd or an oled display using the internal RTC of my board. I have the STM32 Nucleo f401re.Can somebody help me?Thanks and Regards
I am trying to communicate with CAN, but it seems that I am not receiving Rx. I would like to know the reason for this static void MX_CAN2_Init(void) { /* USER CODE BEGIN CAN2_Init 0 */ /* USER CODE END CAN2_Init 0 */ /* USER CODE BEGIN CAN2...
Hi All,I was looking for an EMI Filter for SD card interface in STM32H753VI design. I am going to use a 4 bit mode micro-SD card. I came across these two parts for which I am not sure whether they are compatible with SD memory card specifications ver...
Hi, I'm using STM32L0 series MCU to configure the RTC to wake up after 24 hour during sleep/standby mode. Understand that we need to configure the Wake up clock to use 1Hz with 1 bit wake up counter added so that it can have the wake up time from 18h...
About once over 10, the MCU seems to hang after NVIC_SystemReset() call. Notice that:The MCU restarts correctly after poweron reset,NRESET set to 0 then 1 does NOT restart the MCUWhen MCU is hung, the NRESET Level is correctly UP (thanks to internal...
Hi,I want to get the PVD on a STM32H743 running in order to write some data to the flash, which did not work for whatever reason. So, as a first step, I tried to implement an interrupt which just pulls a GPIO-pin high and check it with an oscilloscop...
