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,...
Greetings, I am trying to blink LED using baremetal programming. I am just starting bare metal programming. My LED on Nucleo - F070 board is not being turned ON. I checked register values on data sheet and user manual and it seems to be correct. RCC ...
How to connect two MIPI DSI LCDs to an STM32 microcontroller such that both displays receive identical data?
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...
hello all;i wondered if there are good guidelines for power consumption vs. clock, and, how low can the processor clock run? complex, i think, especiallly if one needs to run certain peripherals like ADC, or i2c... thanks!
Hello, ST expertE.g. GPIO PD4 functions as falling edge interrupt pin on STM32F407. Before the falling edge this interrupt is disabled by HAL_NVIC_DisableIRQ(EXTI4_IRQn). What happened if HAL_NVIC_EnableIRQ(EXTI4_IRQn) is executed after the falling ...
