Hello, so I was originally using printf with uart3, and that seemed to work fine. The characters were being printed as expected on a PuTTY terminal that I was using. I was using the following code:/* USER CODE BEGIN PV */ UART_HandleTypeDef *uartHand...
Setup: NUCLEO-H503RB with X-NUCLEO-IKS4A1, using STM32CubeIDE. To familiarize myself with I3C, I am playing around in this setup and have some source code which causes I3C interaction between the controller (Nucleo board) and two targets (daughter bo...
Hello,I have a STM32H75x design and suffer from read errors in DDR timing, no matter if run at 50MHz or slower.It seems that the data hold time of 1ns the H7 is violated. The data output hold time of the SPI NOR MX25L12845 flash is 1ns, which seems t...
Hi,I am currently using the following microcontroller (STM32F100C8T6B) in my design. I am using the STM32CubeIDE and I trying to build the project, but I am getting the following compiler errors from the "core_cm3.c" fileError: registers may not be t...
Hello Experts,I'm using the STM32L476 in one of my projects, with the main system powered at 3.3V (VDD), and a 1.55V coin cell (Murata SR621SW) connected to VBAT for RTC backup.The tamper pin (PC13) is connected to a normally closed (NC) anti-tamper ...
I've been getting some weird hard faults on an STM32U073RCT, which I've tracked down to the following conditions- In stop mode, waiting on an interrupt.- Debugging, with debug in stop mode enabled.- Interrupts are disabled.- An RTC interrupt occurs.W...
Do I understand the datasheet correctly when I believe the internal 2.1v reference is something internal, and the AD is still operating within VCC/3.3v as upper limit? Copilot suggested this: // Enable ADC1 and configure itRCC->APB2ENR |= RCC_APB2EN...
Hi,I am experiencing a packet loss issue using Peripheral-to-Peripheral DMA between UARTs.While Peripheral-to-Peripheral configuration is referenced in the STM32U585's Reference Manual, it is not available in the HAL library. Therefore, the DMA is co...
Hello, I use an external flash in memory mapping mode and I have a strange problem. The application is executed from the internal RAM, while the checksum is calculated on the data from the external flash (simple summing of successive bytes in a loop)...
Hello,I have a question regarding VBUS sensing on STM32N6.First off, I found theGuide to USB development resources on STM32https://community.st.com/t5/stm32-mcus/guide-to-usb-development-resources-on-stm32/ta-p/790803I also read AN 4879. I want to us...
