1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows:  The output is as follows:  It can...[Details]

What is SYSTICK: This is a 24-bit system tick timer, SysTick, with automatic reload and overflow interrupt functions. All microcontrollers based on the Cortex_M3 processor can obtain a certain time ...[Details]

In recent years, in order to meet the needs of social development, more and more companies have entered the fields of smart phones, artificial intelligence, VR , AR, etc. After seeing the d...[Details]

From the functional classification, it can be divided into: 1. Active control ADAS: ACC/AEB/LKS, etc. 2. Warning ADAS: FCW/LDW/PCW, etc. 3. Other auxiliary ADAS: BSD/ADB/panora...[Details]

Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]

STM32 has 2 watchdogs: independent watchdog and window watchdog. Independent watchdog IWDG: A system fault detector that is independent of the system and is not affected by the system because it has ...[Details]

The calculation formula of the watchdog feeding time (watchdog overflow time) is: Tout=((4*2^prer)*rlr)/40 Tout is the watchdog overflow time (in ms), prer is the watchdog clock prescaler value (...[Details]

Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]

Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]
