Wiring Diagram

Pin Connection Description

• Sensor: 5V Pin --- (Connect to) --- Controller: VIN(5V)
• Sensor: GND Pin --- (Connect to) --- Controller: GND
• Sensor: RX Pin --- (Connect to) --- Controller: 26/TX
• Sensor: TX Pin --- (Connect to) --- Controller: 25/RX

Sample Code

Configures the 64x8DTOF sensor to single-line mode, acquires Line 4 data (X/Y/Z/I) and outputs via serial with error prompts.

#include "DFRobot_64x8DTOF.h"
DFRobot_64x8DTOF dtof64x8(Serial1, SERIAL_8N1, 25, 26);
#define LINE_NUM 4

void setup()
{
  Serial.begin(115200);
  while (!Serial);
  while (!dtof64x8.begin());
  Serial.println("Configuring frame mode: Single Frame...");
  while (!dtof64x8.configFrameMode(DFRobot_64x8DTOF::eFrameSingle)) {
    Serial.println("configFrameMode failed, retrying...");
    delay(200);
  }
  Serial.println("Configuration Single Frame Successful!");

  // Configure single line mode (retry until success)
  Serial.print("Configured multi-point mode: line=");
  Serial.print(LINE_NUM);
  Serial.println(")");
  while (!dtof64x8.configMeasureMode(LINE_NUM)) {
    Serial.println("Configuration failed, retrying...");
    delay(200);
  }
  Serial.println("Configuration successful.");
  delay(300);
}

void loop()
{
  Serial.println("12345");
  int cnt = dtof64x8.getData(300);
  Serial.print("Got points: ");
  Serial.println(cnt);
  if (cnt > 0) {
    for (int i = 0; i < cnt; i++) {
      char numbuf[16];
      Serial.print(1 + i);
      Serial.print(": X="); sprintf(numbuf, "%04d", dtof64x8.point.xBuf[i]); Serial.print(numbuf); Serial.print(" mm ");
      Serial.print("Y="); sprintf(numbuf, "%04d", dtof64x8.point.yBuf[i]); Serial.print(numbuf); Serial.print(" mm ");
      Serial.print("Z="); sprintf(numbuf, "%04d", dtof64x8.point.zBuf[i]); Serial.print(numbuf); Serial.print(" mm ");
      Serial.print("I="); Serial.println(dtof64x8.point.iBuf[i]);
    }
  }else {
    Serial.println("getData timeout or error");
  }
  delay(500);
}

Result

The serial port continuously outputs data of 64 measured points in Line 4.
