Please let me know if there are any hardware or sofware specifics for connecting TCXO to the STM32G474 series? What should pay special attention to?I use FT2MN at 40 MHz. Its output was connected through a 10 pF capacitor and a 220 Ohm resistor, in s...
Hi.I'm trying to configure a wake-up alarm (Alarm A) to wake up (for a test) after 5 minutes, being time 0 when I turn it on, but I can't even make it work the first alarm because it keeps waking up every 30 seconds or so.I'm using the U585.Sometimes...
Is it ok to keep unused peripherals in perpetual reset, by leaving their RCC_APBRSTR_*RST (or similar) bit set?Maybe differences in power consumption?This is not for a specific STM32 family.I'm just looking for advice by people with more experience, ...
Hi all, I have already searched on the forms and in general did not find an answer to my problem, I will be very grateful to you for help.I need to create an output signal with a frequency of 100 Mhz as CLK in STM32H745. I used the Discovery Boards ...
I saw at least one person elsewhere mention this (but got no answers).On the STM32H503 (LQFP48 pin package)...This configuration:HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSE, RCC_MCODIV_5);Produces no output on the MCO1 pinbut changing it to this:H...
* In the reference manual RM0503 rev2, in §5.4.4 (description of RCC_PLLCFGR), the description of PLLR[2:0] indicates:Caution: The software must set this bitfield so as not to exceed 54 MHz on this clock.* In the reference manual RM0503 rev2, in §5.2...
Hello,STM32F103RB microcontroller.The Figure1 (see attached image) shows clock tree of STM32F103RB microcontroller. Before TIM6CLK, there is a block, which is highlighted in red rectangle. What's IF (APB1 PRESCALER = 1) x1 ELSE x2 label in this red ...
Hello. I have a STM32H747XI project. This MCU has both CM4 and CM7 cores. I can reset both of them, when I use NVIC_SystemReset() function. How can I reset only CM7 core from CM4 core?
Hi,I am having uart baudrate problems while HSI clock as uart source clock. No problem with PCLK as source with the same uart. In Cube IDE (V1.16.0) and F7 software package (V.17.2), I get different values for HSI_CALIBRATION:Ide gets as 0x10 while r...
