STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi, My requirement is when User button 2 is pressed, need to change the speed of the motor. So, I tried to set, when userbutton2 is pressed, motor should start/stop as the function already set in userbutton1. But there is no change in the working. ...
Hi everyone!I am building a portable device wich has a batery, obviusly, and the MCU is the STM32F042. I need to use an USB to program it and charge the batery. Anyone can provide me with any schematic that I can use for the USB conections?Thank you.
I'm having problems getting my software to work with FDCAN2 on the STM32G474e-EVAL board. It works with FDCAN1, but w/ FDCAN2, messages accumulate in the Tx buffer until I get buffer fill errors.I built the FDCAN_Com_IT example from the latest STM32G...
Hi @all,we have an application, where we use the LSE. In due to weaknesses of the part we use, the LSE can fail sometimes.If I then use the __HAL_RCC_BACKUPRESET_FORCE() and __HAL_RCC_BACKUPRESET_RELEASE() to reset the LSE and LSI system, also the SR...
Is it necessary to enable and define the USB-port in CubeMX in order to be able to use the USB-DFU bootloader mode? And if so, what should the settings be for the STM32F415?
Hi,I'm trying to use the TFM (Trusted Firmware M) example application from the B-U585I-IOT02A board. On first attempt the application compiled, flashed (via TFM_UPDATE.sh) and runs. But now I want to make changes to the system and after compiling the...
Hello. I have set protection level 2 in stm32f407. Now I need to change the project a little bit, but st-link/v2 can't connect to the target. How will I able to reset level 2 and do 'mass erase' that chip?Thanks.
Hello, I've been trying to calibrate the system clock of a Nucleo-64 board (STM32l152) using approach proposed in AN3300 to compensate the temperature error. The proposed solution works fine with HSI clock running at 32MHz. At room temperature the op...
Hi. I have developed a CAN based protocol to a Bluepill and now I need to test that on the Nucleo board as well. I have been trying this for a while now and for some reason CAN messages are generated from the Nucleo board. The code was working fine w...
