XKC-007Y的接线板是4针单排引脚封装，电源引脚VCC，控制端tr

XKC-007Y wiring board is a 4-pin single-row pin package, power pin VCC, control terminal trig, receiving end echo, ground GND, pin definitions are shown in Table 3-4. XKC-007Y communicates with the single-chip microcomputer via I / O port. When the single-chip microcomputer sends a high-level signal to the control terminal trig of the ultrasonic module, the control board automatically generates 8 40KHz square wave signals and returns, and at the same time automatically detects whether a signal returns If a signal returns, the receiver echo sends a high level to the PC8 port of the STM32F103, assuming that the duration of the level on the PC8 pin is t, the distance of the ultrasonic ranging is L, and the ultrasonic can be carried out by publicity 3-1 Calculation of ranging distance.

The XKC-007Y's terminal board is a 4-pin single-row pin package, power pin VCC, control end trig, receiver echo, ground GND, pin definition as shown in Table 3-4. XKC-007Y and microcontroller using I/O port communication, when the microcontroller to the control end of the ultrasonic module trig to send a high-level signal, the control panel automatically produces 8 40KHz square wave signal and return, while automatically detecting whether there is a signal return If there is a signal return, the PC8 port from high level to STM32F103 is sent through the receiver echo, assuming that the duration of the level on the PC8 pin is t, the distance of ultrasonic range is L, and ultrasonic distance measurement can be calculated by publicizing 3-1.

The terminal block of xkc-007y is a 4-pin single row pin package, with power supply pin VCC, control terminal trig, receiver echo and ground GND. The pin definitions are shown in table 3-4. Xkc-007y communicates with single chip microcomputer through I / O port. When single chip microcomputer sends high-level signals to trig at the control end of ultrasonic module, the control board automatically generates 8 square wave signals of 40KHz and returns them. At the same time, it automatically detects whether there is signal return. If there is signal return, it sends high-level signals to PC8 port of STM32F103 through echo at the receiving end. Assuming the duration of level on PC8 pin is t, super The distance of acoustic ranging is L. the distance of ultrasonic ranging can be calculated by publicizing 3-1.<br>
