Hi all, I have a SparkFun 2D Barcode Scanner Breakout. When plugging it into any PC it initialises just fine (light comes on and it beeps) but that’s it. I can’t get it to scan any barcode. I tried USB-COM as recommended but then tried others and also under different lighting conditions as well as printed and on-screen. So I am stuck. Does anybody have any troubleshooting advice for me, please? (I did have had a look at the YouTube video and the manual, but no joy).
When I press the trigger button the LED and laser both come on and cuts off again after 8s as standard, so functioning looks like it does on the YouTube video but no barcodes get scanned no matter how close or far away I go with the scanner.
Hi, unfortunately, there is nothing to share really. My intention is to use the scanner as part of a larger Arduino build (using UART). However, I have not gotten that far as I was simply trying to set the unit to use aerial communication by scanning the “USB-COM” barcode on page 23 of the manual. This was with the unit connected to a laptop running Pop!_OS via USB cable. My expectation was that once I scanned the barcode the device should be visible as /dev/ttyACM0. Nothing happened though. So I plugged the device into a Windows 10 system and again it initialised and pressed the trigger button which had both the LED and red light come on but it did not read the barcode. I have tried this on both computers in different light levels and with the barcode printed or on a monitor, but no luck.
