I experience a strange problem with I2C, DMA and the latest STM32U575ZI-Q, not seen on L4 and H7 MCUs.After a successful data transfer from SMBus target (slave) to controller (host) the last PEC byte stays in RXDR registry. On the next transfer in th...
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...
