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]
A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
The clock system of STM32 can be directly summarized in a diagram (from the STM32F10X reference manual). The following is an analysis of this diagram 1. STM32 input clock source 1.1 Function of cl...[Details]
This program sets the LED running light and the 0-16 numbers of the 0th position of the digital tube to light up in a cycle. The digital tube program cannot be put into the main function, because the...[Details]
Requirements: Set timer T1 as an external event counter, count 500 pulses every time, then switch T1 to timing mode and output a positive pulse with a width of 10ms at P1.2. Over and over again. A...[Details]
