The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[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 two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[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 STM8L contains a 12-bit ADC with 25 input channels, including an internal temperature sensor, an internal reference voltage     As can be seen from the figure above, there is an internal re...[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]

Design a program for the 51 single-chip microcomputer. It is known that the crystal oscillator frequency of the 89C51 single-chip microcomputer is 12MHz, and it is required to use T1 timing to output...[Details]

    I have been working on single-chip microcomputers for several years, and I have always wanted to make a series of summaries. It happened to rain today. As the saying goes: Rainy days are good for...[Details]
