Hi everyone,I'm encountering an issue with the reset cause on my STM32H723VE microcontroller.Whenever I perform either a software or hardware reset, the RCC->RSR register does not retain any value—it always reads as zero.Here’s what I’ve observed usi...
I AM USING STM32F446RCT6 MICROCONTROLLER HAL_TIM_OC_Start_IT(&htim8, TIM_CHANNEL_2); HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_4, (uint32_t *)gPWMData1, gPWMData1LastIdx); // trans is generated HAL_DMA_Start_IT(&hdma_tim8_up, (uint32_t)&gPWMData2[r...
Hello everyone,We're working on UART interrupts and would like to wake up the MCU from STOP1 mode to begin UART communication. We're using USART1 as the LoRa peripheral for VCOM instead of the default USART2, in a LoRa End Node architecture. I'm work...
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...
Hello friends : )I've recently tested the NUCLEO-G491RE board for an upcoming redesign.Current design relies on quite tough interrupt latency so here is where I begun.As I understand, with no FPU usage (in isr) (ASPEN + LSPEN = 0) one could expect up...
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'...
Hello,I was looking into this wiki tutorial on setting up a UDP echo server by @mƎALLEm , and the clock configuration caught my eye and wanted to confirm a few things.On the nucleo board , the 8 MHz crystal (X3) is not soldered and the 8 MHz clock si...
