I am unsure if I correctly understand the power consumption of the N6 Family. I want to supply the MCU with 1,8V and use the internal SMPS to supply Core with 0,81V.When it comes to designing the 1,8V voltage source, how much current do I have to exp...
I'm trying to calculate if I need an external resistor with my HSE crystal (24MHz, 18pF, 50R) but the suggested formula example does not give the shown result. So is the formula or the result wrong or have I misunderstood something?Below example from...
Hi,I made some custom PCB's with a STM32L476RG. Here are some of the features:-USB-C connector (CC channel configured as device) with DM/DP routed to PA11/PA12.-Step down converter 5V (VBUS USB) to 3.3V (VCC for most components)-Tactile switches for ...
Board: NUCLEO-H723ZGMCU: STM32H723ZG (applies to others as well)Reference manual: RM0468 Rev. 3 Link Dear community,I want to do a phase measurement of an approx. 75kHz analogue sine signal with respect to the HSE clock. For that purpose, I aim to t...
This is in the Reference Manual for the STM32G4 series advanced Arm®-based 32-bit MCUsThanks,Chris
Hy every one,I'm facing up the WWDG usage on a STM32H755 MCU.I noticed that WWDG peripheral has 2 interrupts: normal one and the early wake-up EWI one.What is the difference?Manual is not clear! Thanks in advance
Folks,I have a bootloader for an M0 which works without using interrupts. It works in that it loads the new app, the CRC in the new app matches and I then try and jump to 0x8004000.In the past I have used a couple of different methods with M3/4 to bo...
Dear together, For the past dew days Im stuck kwith UART communication with DMA.To start with, I am implementing TX now. Later I will implement RX. I have managed for TX to work without interrupt. As per my application, I need Interrupt to inform the...
I'm using HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 32-bit-addr, 64-bit-data) and it crashes with an 0xfffffff7 exception. Has anyone else seen this? I've checked that the addresses are aligned to 64-bit boundary.
Dear STMicroelectronics Support, I am working with the STM32H723ZG-E01 board (Serial: A230801274) and encountering an issue where CAN communication is not functioning as expected. Based on the documentation, I have configured the FDCAN1 interface to ...
