Hello, Am working on STM32L412RBT6. We made a custom PCB for our product and Am trying to PD2 as digital output as toggle function. I can't able to find any high output at PD2. The pin PD2 is always remains low. Please help me on this
Hi Guys, New in STM32 design. We are going to use STM32G4 MCU (specific P/N hasn't been selected yet).We want to use dual image boot (for upgrade option). I need to choose an external QSPI flash for that.What is the maximum image size for STM32G4? Th...
I am using the STM32 G431RBT6 chip and UART 3 for data transmission. The transmission works normally, but after about 20-30 minutes, it suddenly stops completely. Here is the function I am using to send data: bool SendByteUart3(uint8_t byte) { HA...
I am currently working on a project using the STM32U575ZI-Q microcontroller. I have successfully developed a bootloader for my application. However, I am encountering a critical issue where the program fails to jump from the bootloader to the main ap...
I have developed a program that performs IAP (In-Application Programming). I am using single bank mode.The manual states:"An on-going Flash memory operation does not block the CPU as long as the CPU does not access the same Flash memory bank."However...
Hello, I have a question about the FSMC and FMC protocols in the F4 series. Well, I have a configured 4" waveshare display configured for FSMC in STM32F407G. Due to lack of space in the flash, I am forced to add memory (I want to do it using QUADSPI,...

Hello,I am trying to implement the FDCAN in classic mode on the STM32G491 without the HAL. But I am havin trouble understanding how to configure and then use the CAN SRAM. I am not using the HAL nor CMSIS nor anyting else. Just the basic register def...
您好： 我现在使用的RTL8211E-VB的PHY芯片，，PHY芯片的数据手册中明确表示了，ETH_TX_CLK信号是需要由单片机产生。如下图所示： 而STM32H743VGT6单片机在HAL_ETH_Init函数中会在下面这段代码中返回错误： /* Wait for software reset */ while (READ_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR) > 0U) { if (((HAL_GetTi...
