Hi, Version 1: I have a circuit that has an Attiny 2313 chip with an assembler program programmed into it. The purpose of the circuit was to log data from a ps/2 keyboard and transmit it via Bluetooth. Version 2: I then had a programmer add a custom keypad to the circuit. It was done by re-arranging the pins and programming the keypad matrix into the Attiny2313. Everything up until this point works perfectly. Now I need to add a barcode scanner to the whole setup. This barcode scanner has a ps/2 connector, data from it is just like a normal keyboard. Infact it gets plugged into the keyboard (keyboard wedge). But the problem is data does not get recorded on the attiny2313 circuit. (If I revert to Version 1, it gets recorded) Hence I suspect that the programming involved in adding the...

Hi, I have a circuit that has an ATiny2313 IC on it, that is programmed with the attached program. (source code in attachment). It basically handles data from a PS/2 keyboard and records it on to a memory chip and also communicates with a bluetooth device. On the IC 11 pins are currently being used 9 pins are free. What I need is the program to be modified to re-program the IC so that another device can be attached via a Y cable and the data from that device also get recorded like the ps/2 keyboard. (note:- both the devices will always work one after the other, and never be used together. Hence there is no confusion of data, and just a simple Y cable is used, no need to have any special software to seperate the data) The other device that I wish to attach to the system. Is a panel of 12 sw...
