Fluffy2 is a SX programmer for people who have already experimented with PIC chips, and want to try out the Scenix SX family. To build it, you will need a PIC16F84 (a 16C84 will probably also work, but I don't have any to test!). Note that this implies you should already have a working PIC programmer.

Fluffy2 Programmer is based on the Fluffy Programmer by Ben Stragnell, but it has some updated features:

   * Support for all SX's chips, including new and old revision (even datecode 9812 etc.)
   * Uses 38400 or 115200 as serial baudrate (jumper selectable)
   * Automatic sync signal detection (specially for those old SX's)

IC-Prog only supports the serial interface, using 115200bps Also make sure that the VPP at the SX chip is 13v (=) because otherwise you'll have problems erasing (codeprotected) old parts!!

Basically A0 and A1 control the SX OSC1 voltage level - both low implies 0V, A0 high (and A1 low) implies 5V, and A1 high (and A0 low) gives 13V. If you want to implement your own power supply circuit, it shouldn't be too hard.
