Hello,we are developing a device with STM32F765VIHx.We are experiencing a big issue with USB (USB-Device Full-Speed), when connected to a Windows PC.The USB is configured to be a Virtual ComPort.Windows sometimes recognizes the device, sometimes the ...
I am using the STM32H562ZGT to generate center-aligned PWM with TIM1. Since I also want to use TIM1 for 20kHz periodic interrupts, I set the Period so that overflow/underflow occurs every 40kHz and set the Repetition Count to 1. This ensures that UEV...
Edit by ST Moderator: This post has been translated from Japanese to comply with the ST Community Terms and Conditions (§10.2). The question is about the interrupt processing of the STM32F401RE. After the STM32 was started (after the programme was st...
Hello, I have a question regarding write access to a PSRAM connected via XSPI in memory mapped mode on a STM32H7RS. I do not completely understand if having the PSRAM memory mapped makes it available to the ECU as if it is internal RAM, meaning that ...
I am interfacing a 5V PWM signal with an STM32F030K6T6 MCU using PB0. According to the datasheet this pin is 5V Tolerant. In the past, regardless of a pin's "tolerance" to 5V I have always used a level shifter to change this 5V signal to a 3.3V sig...
I am using uart on STM32L07 to simulate 1-wire for operating ds28e22. 1-bit timing is more than 1us and less than 2us. When I set baudrate at 666666 which meant 1 bit timing was 1.5us, I found the rising edge was too slow (more than 1 us). So I want ...
HiCan you tell me how I can calculate a value for ARR for timer 2(32bit timer) and timer3(16bit timer)I am using STM32F407 APB1 timer clock is 12MHz prescaler is 6
Hello.Is it possible to reset the product state from closed to openinternaly by the firmware on a STM32H563?Can i do this easy by rewriting the ProductState to 0xED, or do i need additional provision information or the provisioning password to do thi...
Hello,I have a STM32G431KB on a custom PCB and got the CAN bus to work. The only problem I have is that the TX FIFO is always filling up and the bus stops after 127 errors.The workaround I have is to abort the TX request./* Add message to Tx FIFO */ ...
I'm developing a custom board with an STM32U5 MCU and a MX25UM51245 NOR flash memory. I'm building upon this example, which works flawlessly, but I don't want to format the memory every time the code runs. To achieve this, I disabled the Driver calls...
