Bertrand Irakoze Posted April 2, 2020 Report Share Posted April 2, 2020 I'm working on a scanning project that scans barcodes of 2 parts during assembly to compare them. I'm using 1 scanner connected to the serial port. I need the operator to scan the first barcode, then he should be prompted to scan second barcode, then compare the 2 strings. I need help on how to prompt to second scanning after handling and saving the first input. Should I just fill the buffer with 000 then put a rung to receive data through the port again?
