README file for yampp-3 source code 2001-11-22 This is the current state of the yampp-3 source code, 2001-07-22. Note ! This file is intended for a 7.3728 MHz yampp-3 ! A few fixes since previous versions : * Keyboard enabled. By mistake, the PD4 pin instead of the correct PD3 pin was used in the keyboard routine. * Fancy triangular volume indicator added (by Sebastian.Lux@epost.de) * Error: 01 should now be history. A few fixes since the 2001-05-27 version : * Pullup activated on IR-Input makes it possible to run the player without an IR-receiver. * Pullups activated on IDE bus on input. Should improve signal quality on the bus. * Improved the Sector Read code. 2001-05-27 notes ---------------- This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it's maximum at 1F40 bytes. A .ROM file is included if you don't have the compiler set up. For now, the documentation is in the code ;-) Have fun. Jesper Hansen jesperh@telia.com www.yampp.com www.myplace.nu
