I am trying to use the PLL1 fractional PLL on a Nucleo-U545RE-Q board to fine-tune a frequency measurement. RM0456 rev 5 has the following procedure to adjust the fractional PLL:"If the application intends to tune the PLLx frequency on-the-fly, then...
HiI have made a custom PCB based on STM32H723VGT MCU and KSZ8863RLL with interface RMII. I have followed the Hardware Design Guide for the KSZ8863. Including 100 Ohm impedance from RJ45 to PHY and 50 Ohm impedance from PHY to STM32. Length matching i...
Just reading through the wikipages:https://wiki.st.com/stm32mcu/wiki/Introduction_to_Azure_RTOS_with_STM32and chapter 2.2 refers to:User is granted production, provided the development is performed on an MCU that is listed officially by MicrosoftIs t...
Entering low-power modes, especially the Standby and Shutdown modes, is another mostly software related disaster from ST. Additionally there also seems to be one or two hardware bugs and/or undocumented conditions. This topic provides an example of h...
Hello: I use STM32CubeIDE 1.16.0 to develop an OTA feature in STM32H7A3ZIT6: The firmware should be programed at flash address 0x08000000,and run in ram, it will receive the whole update image in temporary memory and then program into the flash...
HAL_RCCEx_GetPLL2ClockFreq() computes the frequency of the three outputs of PLL2. When PLL2 is in Fractional N mode it reports wildly inaccurate frequencies which can affect the setup of other peripherals like the SPI/I2S port.The problem is that the...
Hi,I am working on a project which will require a connectionless CTE to be added to the advertisement. From what I understand, there are not currently any examples of a configured CTE beacon. What would be the best example project to modify to create...
Posted on February 26, 2017 at 07:10 Hi Everyone, I'm trying to read from the USB keyboard with a custom board STM32F205RCT6 MCU. I am using USB FS host (host only) with HAL library.but it just works with some keyboards! Other keyboards are...
Hi Community, I am using the Nucleo-H723ZG board for data receiving from the camera by utilizing the spi and processing the data then transforming the data through UDP to another program. The program can run for several hours without problem. But the...
Hi,I'm using a STM32L452 and launching the bootloader in System Memory by setting the Boot0 pin to high and resetting. This launches the bootloader successfully.I'm using UART1 on PA9 and PA10.However, when trying to write the flash using the STM32_P...
