We are developing some devices which will use the usb as a virtual serial port to mainly update our devices with our own bootloader. Do we then need an own vid and pid for usb? Or is it also possible to get and use the vid and pid by STM?
Hi,I'm using STM32H743ZI. I want to measure the LSI frequency by timer TIM16.Configure TIM16 by CubeMX (5.2.1)"Input Capture direct mode from Remap""TI1 remap capabilities for TIM16 => "TIM16 TI1 is connected to RCC LSI"TIM16 global interrupt => "Ena...
Hi all,I do have a problem with the Interrupt Mode of the I2C interface. I started with the example provided by STM (I2C_TwoBoards_ComIT). I do not use two boards but one board as slave and the master is an FTDI FT4222. So sending from the FT4222 to ...
I am using STM32L476.I want to enter the Stop 2 mode and use LPTIM1 as a Timeout wakeup unit.The code is written such that the LPTIM1 wakes up the MCU from Stop 2 mode after every second. The LPTIM1 takes too long to wakeup the MCU for the first time...
I develop an own LIN slave node software stack for the STM32F103RB. This stack has to pass all tests from the LIN Conformance Test (according to ISO 17987-6). This test is a customer requirement.Actually the software and/or the hardware could not det...
Hi,I have configured MCU in Sleep Mode, I have Configured SPI,UART and Some GPIO. and also configured Interrupt RTC. I have Wrote entering Sleep mode like,main(){ MX_GPIO_Init(); MX_LPUART1_UART_Init(); MX_SPI1_Init(); while(1) { Disable_Pheripheral...
Hi, Most of the STM32G4 CubeMX examples configure the ADC clock as synchronous clock mode divided by two,and the AHB ADC bus clock as 150MHZ. If I understand correctly, the ADC clock would be 75 MHZ for this configuration. The problem is that STM32G...
Hello,Can someone let me know how to bring STM32H753XI-E02 Eval board back to its original status (i.e. factory default)?I tried to implement Quad SPI application and found the Eval board did not work well. The USB port (CN23) did not communicate and...
With some other microcontroller it works propetrly.Why with STM32F072CBT6 doesen't works?
