Power Window Anti-Pinch System Using AVR Flash Microcontroller
Automatically closing power windows or doors on cars present a potential risk of jamming, crushing and possible injury. They must be able to reverse movement to prevent the force applied by the motor from exceeding normal limits. This feature means that speed, current and glass position must be constantly monitored.

PIC18Fxx MCU IO Settings Notes
General IO structure Precautions: Analog Select Registers (ANSELx): After reset, the ANSELx bits default to analog mode. To use any pin as a digital general purpose or peripheral input, the corresponding ANSEL bit must be initialized to 0 by user software. Open-drain control register (ODCONx): When using the I2C pi

Design of portable magnetic memory detector based on PIC16LF873A microcontroller
In engineering, nondestructive testing (NDT) is often used to detect defects in equipment and components. Traditional NDT methods include ultrasound, eddy current, magnetic powder, coloring, etc. However, these methods can only detect defects that have already developed and are powerless for the early diagnosis of fat

Microcontroller matrix keyboard scan driver and circuit analysis
Taking the 4X4 keyboard as an example, first make the circuit as shown below. Then connect HOR1-HOR4 to the input pins of the microcontroller; LON1-LON4 to the open-drain output pins of the microcontroller. Note that these 4 pins must be set to open-drain mode! In the program, first the IO connected to LON1 outp

Design of serial A/D driver for 89C51 microcontroller and TLC2543 chip
The conversion result of the serial A/D converter is output in a serial manner. The serial output of digital quantities can simplify the system wiring, reduce the area of the circuit board, and save system resources. The following uses TLC2543 as an example to introduce the design of the serial A/D driver. The int
