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'...
Hi Mr/Mrs,I have one problem about flash software for Stm32F103C8T6. When I compile and flash software for the first time, everything is OK. But, I have changed code and compile successfully then software can not flash to board. I see that there is o...
Am I seeing this right? According to the datasheet, the STM32F413xG/H only maps USART3_RX to PB11, PC5, PC11, and PD9. All four happen to not exist in the STM32F413CG/H variants with the UFQFPN48 package!Bit weird this doesn't seem to be noted anywhe...
Hello hope some one can shed some light please,I have a STM32F446RE board with SPI1 setup for 8pin SPI FRAM memoryI have written my own firmware using DMA / SPI1 to read and write to this FRAM ICThis is a very fast no volatile memory IC that does no...
Hallo,for security reason I have to stop HRTIM generating 3-phase signal for PMSM motor.It works as described in RM0433 (37.3.23) with DBG_HRTIM_STOP = 1: when debugger stops MCU predefined "FaultLevel" appears on outputs as expected. HRTIM goes into...
Hi,I have an stm32G0B1 that i'm working on. I want to use a timer "TIMER2" but the block diagram of the board doesn't not give the AP2B2 clock bus. I know with other boards is usually mentioned. Where do I go to look for it, as I have looked and I st...
When "Activating clock source" is ticked in RTC module, my MCU doesn't start up if I reset it from RST button. But as soon as I switch the RCC clock source to LSE external 32.768khz crystal and change RTC Clock Mux to LSE, it works without a hitch. I...
I'm using the STM32U031C8U6 with STM32CubeIDE 1.19.0 and can't figure out how LPTIM1 works.I created a new project and enabled LPTIM1 in Device Configuration Tools (Mode: Counts internal clock events). In the NVIC Interrupt table tab, I enabled the i...
