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 ...
I'm working on a project with the STM32H503CBU7 which requires USB. I have a 32MHz external crystal on my board that appears to be stable. The chip works and can be programmed and such. I also troubleshot out other physical issues like cold joints an...
I am using I2S (SAI) on the STM32L433 nucleo board and using the internal MSI RC as the clock source.I also have a 32.768kHz LSE external crystral which I believe helps to make the MSI RC clock more accurate when used with PLL.Is the internal MSI RC ...
Hello, we have device with very old TFT display which is dying. New one is unable to obtain. It has similar interface as DCMI: vsync, hsync, pixclk, D0-D8.I have connected these clock/data lines to DCMI port, but interrupts was not triggered.Here are...
Hi, I am using an STM32H755XIH6 MCU in a custom design. I want to use only LDO supply configuration for the internal power regulator that provides the VCORE and I don't really intend to use the SMPS configuration. My schematic has some hardware mista...
Hello, I am experiencing the following issue with the STM32L433RCT microcontroller I am using: when I pull the NRST pin LOW and then release it to HIGH, the microcontroller does not recover from reset. In this case, power cycling the device does not ...
Hi,how do I start the USB DFU Bootloader with a STM32C071 Nucleo? I tried it while putting Boot0 to high and pressing reset or do a power cycle but the STM32 DFU does not show up in the device manager. I connected USB to the NUCLEO extra USB port of ...
I do a project with the newer STM32 G , C series and i am curious what are the benefits of external clock vs using the internal clock, because it will save cost and layout space ?
I have updated the STM32L4 HAL drivers to V1.13.6 / 14-November-2025 (1.18.2), which has broken my implementation of HAL_UARTEx_ReceiveToIdle_DMA.Is this a fault in the new HAL drivers or does user code need to be updated inside the HAL_UARTEx_RxEven...
Hi,I am trying to configure the internal cooperators in the STM32F051 micro-controller, but in the .ioc file I am able to configure only one Comparator. I require three comparators for my application. Is it possible to configure multiple comparators ...
