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]

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]

The independent watchdog of STM32 is driven by a dedicated internal 40Khz low-speed clock, that is, it is still effective even if the main clock fails. Here we need to note that the clock of the inde...[Details]
