Technical overview
- Interfaces: USB and UART
- Reads both 1D and 2D codes
- Arduino Uno connection example: Rx to pin 11, Tx to pin 12
- Example code uses SoftwareSerial(11, 12) at 9600 baud
- Serial output is read until newline character ( )
- In command mode, response data output can be disabled by changing the scan command to 016 0x54 0x0D
- The flex cable has 12 pins; exact pinout see manufacturer documentation
- Available resources: quick start document, user manual V2.1 (current version), demo code
Commands and examples – verify before use:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(11, 12); //Rx=11, Tx=12
void setup() {
Serial.begin(115200);
mySerial.begin(9600);
}
void loop() {
if (mySerial.available()) {
String receivedData = mySerial.readStringUntil('\n');
Serial.println(receivedData);
}
Scan command (default): [not specified in source]
Scan command (no response): 0x16 0x54 0x0D
