Hi, I'm seeking some advice on using a STM32U5A5 in USB device only via a USBC connection.Any previous USB "device only" designs I've worked on only required connections to D+, D- and ground to communicate. These designs have been USB2x.The U5A5 has ...
Dear ST Support Team,I am developing a USB-based device using the STM32H755 microcontroller.In order to ensure proper identification of the device on host systems, I would like to requestthe allocation of a unique USB Product ID (PID) under STMicroel...
Hi,I am using STM32H7B0Since it has only 128KB flash, I will need to use an external flash to run code. There will be a "host" mcu to control this (with BOOT0 / NRST pin control).I am wondering is it possible to use the built-in ROM bootloader (in sy...
Hi, I'm trying to communicate two microcontrollers (STM32H503CBT6 and a NUCLEO-H503RB) via FDCAN but the STM32H503CBT6 is not sending any messages.Both have the same configuration, but the NUCLEO-H503RB can send (I have checked it with an oscilloscop...
Split from this thread. thanks to @Ozone @Karl Yamashita, this afternoon I have tried to extend can2.0 to canfd with my project of stm32g474vet6. I found some strange things, I think there may be a bug of stm32g474vet6 fdcan module. I modifed the FD...
HelloI am using NUCLEO-G474RE board to sample voltages from the the Battery management board. In the PCB board, I have opamp voltage divider to step down voltages around 24Volts to 2.5V level to be read from the STM. Please refer to the voltage divid...
Hello,The target MCU is STM32L151ZETx (LQFP144), and the main clock frequency is 32 MHz.Normally, the system operates in Run mode, but I plan to use Sleep mode or Low Power Sleep mode when the supply current decreases.My question is: when entering Sl...
Target MCU: STM32L151ZETx (LQFP144)Main Clock Frequency: 32 MHz When the MCU is first powered on, it takes about 41 ms to reach the while(1) loop in the main() function, based on the code shown below. For my product requirements, I would like this st...
I tested the LSE CSS function on the Nucleo-L053, but I found that short-circuiting the crystal oscillator pins failed to trigger the CSS interrupt. The code configuration is as follows plz give a clue or the flow of LSECSSvoid SystemClock_Config(voi...
The Reference Manual for L4 series (RM0394) says on page 1007:"When the LPTIM is running with an asynchronous clock, reading the LPTIM_CNT register mayreturn unreliable values. So in this case it is necessary to perform two consecutive read accesses ...
