Hi i have been trying to downscale a project slightly by replacing an Arduino pro Micro with a ATTiny2313 ic.
currently the arduino gets a serial (RX, TX) string input then forwards it out the USB port as an emulated keyboard.
There are a few integrations i need to make with code (to account for return, ctrl atl shif and modifier keys) but the concept is exactly the same.
I have seen a few projects like this however im not too use to the format they are using and am getting a little confused.
The project i have been following is http://hobbyelectronicsblog.blogspot.co.uk/2013/04/serial-to-usb-keyboard.html
which seems the be very close to what im looking for however i have had some compiling errors using the Arduino IDE
I did manage to get to the point where i could program the attiny using the arduino Uno as ISP however didnt manage to find a good way to flash using a usb- ftdi converter.
