Hi, I am working on a project and having the following problem:My UART DMA is not working. I am transmitting a string, that should be visible in the terminal but it is not. The TX complete callback function is being triggered, so it looks like it wor...
I am trying to get the RTC alarm working whilst also using a periodic wake, I can get each working independently but not both together.If I DON'T shutdown for RTC wakeup, the RTC alarm DOES work.If I DO shutdown for RTC wakeup, the RTC alarm DOES NOT...
Hi,I am working on STM32G474CET mcu. I am trying to use VREFBUFF voltage for ADC channel referance voltage. My configuration looks like the following. When i run the code, it stuck in the HAL_SYSCFG_EnableVREFBUF function. Whenever i check the 'ticks...
Hello All,I got Classic CAN running on the FDCAN3 module of STM32G474CE device using MXCube and other example projects for STM32G474 devices.Problem is, all these example codes have a fixed baud rate of 1Mbps. My application requires thebaud rate be...
Hi ST Community, I am currently trying to evaluate if I can use EXTI GPIO IRQ handlers (function executed at USER BUTTON press) in combination with the STOP3 sleep mode.Firstly, I would like to request, if this is supported by the u5 CPU. Based on th...
Hi EveryOne, I have made a custom board with STM32H7B0 and W25Q128 . where W25Q128 has to hold the user application . I hoped that i can change OSPI in STM32H7B0 to a QSPI config and work with W25Q128 ( which will only work with S...
Hi everyone,I am working on a project where I need to interface an external ULPI PHY (FUSB2805) with the STM32H745 for high-speed USB communication using USB CDC. This is my first time working with an external USB PHY, and I am facing some difficulti...
I have a custom board with an STM32H730 and a LAN8710A PHY, operated in RMII mode. The board is a new design, based on an older board but with some differences (the older board has an STM32H750). My short-term goal is to prove out the hardware -- a...
Hi,I'm working on an STM32G491RE-based project where we need to configure 10 GPIO input pins as external interrupts. Each of these pins is on a different port and mapped to a unique EXTI line (EXTI0 to EXTI10), so there’s no conflict in EXTI line usa...
以上就是我配置的所有内容。您能指出我的配置有任何问题吗？根据上述配置，我的设备现在在开机时无法在计算机的设备管理器中检测为 USB 设备。Edit: That's all I have configured. Can you point out any issues with my configuration? With the above configuration, my device is now not detected as a USB device in the computer'...
