Hello friends, I'm new to programming, but in 1 year I've acquired enough knowledge to make 2 firmwares and everything works accurately, and help from you here. I'm happy.
But I'm trying to accomplish a technical feat, a child's dream! Find out how this reader works and make it work!
I work with access control equipment, which have a barcode reader. This barcode reader only has 3 pins, GND +5V and Signal.
The barcode reader reads when the code passes through the reader in a horizontal movement. Some things influence reading as an example: The speed at which the person will pass the code through the reader's beam.
The point is, I don't know where to start. I've seen in some manufacturers they use a normal PIC pin like RA2 example, no specific pin.
I think the reading is done by converting electrical signals into binary numbers and then converting them into a decimal number.
Someone experienced, could you guide me on how to "try" to start?
Thanks!
