Using a PIC micorporcessor from Parralax would be a less expensive choice. The
programmer comes with sample code for doing both of those things and at $4.00
a pop for the PIC chips and less than $200  for the assembler, programmer,
documentation and a proto board you will have a hard time beating the price.
You can order from Parralx direct or from digi-key. 

Good luck
