I am writing a pygame application that uses a USB barcode gun which behaves as a keyboard. (AFAIK most barcode scanners behave as keyboards)
When you scan a barcode, it rapidly types the text it reads from the barcode. My application is listening for this keyboard input as pygame events, and appending them to a string. This *mostly* works great. The problem I am having is with input that has a lot of repeated characters, such as "9999999" If such a barcode is the FIRST one I scan, I usally only get "9" or "99" instead of the whole string. If I have scanned other things, then I *usually* get the whole "9999999". I am guessing that somehow pygame is throwing away key input events because they are coming too fast and look like duplicates. Has anybody else experienced a problem like this? Does anybody have any ideas for workarounds or further avenues of testing? I should note that when I use this same barcode scanner to scan the same repetitious barcodes into a terminal, or a text editor, or a word processor, I NEVER lose characters, so I am pretty sure this is not a hardware issue with the scanner itself. --- James Paige
