Found this feature mentioned in Segger J-LINK wiki, but it is not clear which targets support it:https://developer.arm.com/documentation/ddi0314/h/Debug-Access-Port/SW-DP/SW-DP-multi-drop-support?lang=enIt looks like a cheap alternative of JTAG cha...
I'm trying to understand the correct way to do self-powered devices with STM32L0. Most datasheets for other MCUs document using PA9 as a sensing pin using an alternate function, but I'm not finding this for L073, which I'm using on a Nucleo L073RZ bo...
Hi,Where can I download the bsdl file for STM32G031? Thanks.Regards,Benedict
HiI have the following problem on my STM32F103C8T for which I have no clue how to continue. I am running the ADC1 with DMA in continuous conversion mode scanning 6 input signals. Everything works fine. Next step was activating ADC2 triggered by TIM1 ...
Hello!I have a question about ESD protection of Nucleo 144 STM32H7 development board. As I've noticed from the schematics the board uses ESDA7P60, ESDALC6V1, USBLC6-2SC6 and USBLC6-4SC6 for ethernet, buttons, SWD connectors and USB.Isn't it easier an...
When transmitting with a UART on this H747 board, a sent string will only get through two characters before HAL_UART_Transmit() hangs. No matter how I format the string (e.g., with or without snprintf() ), this same behavior occurs for UART8 and UART...
Hi,"We are planning to design a custom board using the STM32F103VBT6TR microcontroller and are looking for guidance on how to set up the bootloader section in the schematics. Specifically, we want to enable the ability to reprogram the microcontrolle...
Hi All,I am trying to get my Nucleo-U575ZI-Q to receive low level USART data using DMA. I have set it up to be a circular buffer in the IOC file but everytime I receive 1024 bytes for example after that it won't receive anything.When I call LL_DMA_Ge...
Hello, have been working with my L476RG and was curious if any of the ST accelerometers would be compatible with this board? I didn't see any in the X series of nucleo expansion boards.ThanksDG
Hi, I have a board with STM32H735I.I can only detect the IC when boot0 is tied to 3V3 effectively putting the MCU into DFU bootloader mode. In this mode, I can flash it OK with stlink or even USB-DFU. However, once I tie boot0 to gnd the device won't...
