The PHY chip for HS is USB3320. On the SCH part of UM2198, PIN32 of USB3320 is optional connect to MOSFET. Is it for power on sequence purpose? I can not find the power up sequence requirement for this.Is it requirement of H753's HS OTG?
Protocol support: SPI, UART, USBCurrent Consumption: Ultra LowOperating Voltage: +3.3VSupporting software if any for fingerprint data sensing.
Anyone that knows the details? Seems backwards.CubeMx generates an init-fuction for CAN which eventually calls HAL_CAN_Init(). The very first part of this function is to exit sleep-mode. As per documentation this means "syncing" - waiting for 11 idle...
I have build a IAP bootloader at 0x8000000 and test with a simple blink app at 0x8040000 which works fine but if I add FreeRTOS for the same blink app at 0x8040000 its not working. It jump to the blink application but it doesn't pass the SystemClock_...
Hi, I need to modify the bootloader of the STM32F427 MCU.Specifically, I need to modify the UART portion of the bootloader so that it works with RS485.This should just involve adding a control line for direction flow.So, my questions: Is the source c...
Hello,I have problem with my project on STM32F4. I use Lwip, Freertos, and 3 TCP sockets in separate threads. The first and the second is for the modbus. The third is for the website. When the first and the second socket’s threads are in the waiting...

Hello,I have bought myself the STM32H743 Nucleo. Am trying to explore the environment and learn the working of parts and functions of the board. The board comes with two on-Board USB Ports. One for the ST-Link and the other is to be used as a user US...
Hello!I've been working with embedded software for a while now, but managed to avoid the nitty-gritty of bootloaders most of the time. Now on my current project I have some catching up to do.We are working on top of the reference firmware for the ST2...
