The maximum allowed internal clock for the device STM32F446RE is 180 MHz. The nucleo board has an external crystal of 8 MHz. Using this and a code I obtained from a university website, I attempted to change the system clock to 180 MHz using the PLL.(...
When I use HAL_NVIC_EnableIRQ(64) from CPU1, it interrupts same core (i.e. CPU1 instead of CPU2).
Hi everyone!I am trying to get the lowest power consumption from the STM32L073ZR in STOP Mode.I run my tests with the board powered from external source E5V (no USB connected).I have two Ampere-meters:one measure the current IDD of the microcontrolle...
Posted on August 03, 2017 at 20:26Hi, recently in a project I need the GPIOs on STM32 to operate on 1.8v logic level. By quickly looking through datasheets, it seems many of STM32 can do so, for example, to STM32F407VG, if provide 1.8v to VDD, it ru...
Hi Team,This IC STM32H745XI will support the following power supply configurations 1) Direct SMPS power supply which gives to the core domain 2) Direct LDO power supply which gives to the core domain 3) SMPS ->LDO-> Core domain(1.8v or 2.5v) 4) Exte...
I want to know how to split the flash memory of the stm32f103c8t6 , The one part of memory is used to store the firmware & other part is used to store the settings & configuration through external user interface exe file. Please any one help in thes...

Good dayI can to open nothing *.pdf files on your site via Microsoft Edge (Microsoft Edge 44.17763.831.0; Microsoft EdgeHTML 18.17763). But via Google Chrome your site is working
Hello,This is for the STM32H7, but may be applicable to other STM32 chips.Is there a way to do a continuous DMA stream from a UART without requiring an expected size?I would like to be able to set up a receive buffer with DMA in circular mode, and ju...
