Hello,let say that STM32H753 mCU has connected VBUS (via resistor divider to be sure that voltage on VBUS detection pin (PA9) would never exceed AMR), D-, D+ and GND lines with PC, before mCU core is supplied. At the moment when mCU core is then conn...
Hello,I’m working with an STM32N6570-DK, and I’m trying to run a very simple LED-blinking application as part of the FSBL.When I debug the project using STM32CubeIDE, everything works correctly and the LED blinks as expected.Next, I want to flash the...
Hello! I'm now using a STM32F469 to drive a screen with MIPI-DSI Interface. I need to send the initial codes with low power command transmission, and then drive the screen in video mode. I think LPDT it is supported by this MCU, but I'm not sure how ...
Hi, I am trying to reset HRTIM on an external event using TIM1 TRGO as a reset event. I am trying to make a single pulse every 200ms (5Hz) because I want to make a single puls test. However, I also need a high resolution so I can vary the on time and...
Hi,we are trying to get a 800x800 display to work with the STM32U5G9VJT6Q, using either RGB888 or RGB565 in Video Mode (Burst).According to what we read it is definitely possible. Did we miss something?Could someone please confirm that is definitely ...
Hello, when I was using this chip, STM32F427ZGT6, it could print data, but the delay was incorrect. After 5 seconds, it was only a few milliseconds. Due to the inaccurate delay, the timing sequence became disordered
Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. ...
Dear Sir, My board is equipped with STM32G431 MCU. I found that the UART DFU mode of my board does not work after the flash of the MCU has been programmed. The UART DFU mode can only work with a blank MCU that have not been programmed before. I have...
I call HAL_UART_Init() with LPUART1 at 20Mbaud but when I activate assertion it fail at IS_UART_BAUDRATE().The IS_UART_BAUDRATE() is not correct for LPUART that can have a baudrate up to 53.3 Mbaud.Also for UART, the comparaison in IS_UART_BAUDRATE()...
Hello,I am working with an STM32H563VITx (2 MB Flash) and I am experiencing a repeatable issue when placing two custom sections (.param_defaults and .app_defaults) at the end of Flash.The application runs as long as these sections are removed.But wh...
