Using Systick timer to achieve delay 1. SysTick timer characteristics The SysTick timer is a 24-bit down counter, that is, when vlue is decremented to 0, an interrupt is triggered and the load va...[Details]

1. Basic Concepts of LCD/LCM The structure of Liquid Crystal Display (LCD) is to place liquid crystals between two parallel pieces of glass. There are many vertical and horizontal fine wires between...[Details]

Different from 51, AVR and other single-chip microcomputers, the clock signal sources of msp430 include LFXT1, XT2 and DCO. 1. LFXT1: It can connect high-speed and low-speed crystal oscillators. In l...[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]

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]

ADC Introduction:     ADC (Analog-to-Digital Converter). That is, converting analog signals into digital signals for processing. When storing or transmitting, analog-to-digital converters are almost ...[Details]

Use the STM32 timer input capture module to control 3-way ultrasonic sensors. The  ultrasonic sensor used this time is the common HC-SR04, which is often used in the obstacle avoidance system of smal...[Details]

If you do not use an external crystal on the STM32, the connection method of OSC_IN and OSC_OUT If you use the internal RC oscillator instead of an external crystal, please follow the following metho...[Details]

;Question: The 80C51 single-chip microcomputer has a fosc = 6MHz. It is required to use the T1 timer working mode 1 to perform a timing of 40ms. And P1.7 periodically outputs a rectangular wave with ...[Details]

Homemade LED Electronics   Clocks can be seen in many electronic newspapers and magazines, but most of them need to reset the time and other parameters after power failure, which brings a lot of inco...[Details]
