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 ...
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...
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
Heyho,do all SAIs in all MCUs offer the SPDIF output feature?CubeMx and online MCU selectors do not show this info, no time to check 20 more datasheets.For the few STM32 I know and worked or played with (G4, F7, H7) the answer is yes.Merci!
Using Nucleo-U545RE-Q, SPI2 Full-duplex Master, default GPIO selected by STM32CubeMX v6.15.0 with LL selected for implementation.Config clock for max 160 MHz and prescale SPI by 8 for 20 Mbps. Add GPDMA Ch2/3 for SPI2 TX/RX.I double checked the outpu...
My nucleo f303re board was connected via USB but I was using a resistor around 2.2kohms to 5V. This was fine though and it functioned as normal but when I disconnected the pins on the MCU to move it, reconnecting it back resulted in nothing. While tr...
Hello,Hello, in our project we are using an STM32N6 MCU and an external flash from ISSI with this MCU. Datasheet of the flash's link in the below.https://www.issi.com/WW/pdf/25LX-WX032-064.pdfDuring debugging, we read the flash using standard command...
Hi Team,As we are going to use RAM – IC CY62136EV30 (TSOP-44) in our new project with ST micro STM32F407ZG (LQFP-144).Do we need any impedance matching for 6-layer board?Can you please suggest the same. Crystal frequency we taken 16MHz for the MCU.Th...
