yampp-3 source code 2001-05-27
This is the current state of the yampp-3 source code, 2001-05-27.
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
This firmware translates a PS/2 mouse to a USB mouse. The translator
firmware is entirely interrupt driven (with the exception of sending the
data via USB to the host.) An interrupt is generated when the PS/2 start
bit is received, at which time the firmware will begin its receive routine.
In addition to this interrupt, every 168ms a timer overflow interrupts the
main program and implements one state of the mouse state machine. This
state machine handles sending Bytes to and translating Bytes received from
the PS/2 mouse automatically. All of this is done in the background while
the main program runs in the foreground. The only operation that the main
program implements is sending mouse data to the PC via USB.

一個簡單的ＳＰＩ ＩＰ核，SPI Core Specifications 可以從說明文檔中找到！
The simple Serial Peripheral Interface core is an enhanced version of the Serial Peripheral Interface found on Motorola s M68HC11 family of CPUs. The Serial Peripheral Interface is a serial, synchronous communication protocol that requires a minimum of 3 wires.
FEATURES:
· Compatible with Motorola’s SPI specifications
· Enhanced M68HC11 Serial Peripheral Interface
· 4 entries deep read FIFO
· 4 entries deep write FIFO
· Interrupt generation after 1, 2, 3, or 4 transferred Bytes
· 8 bit WISHBONE RevB.3 Classic interface
· Operates from a wide range of input clock frequencies
· Static synchronous design
· Fully synthesizable
Delphi and C++ Builder component for direct access to IO ports on Windows 95, Windows 98 and Windows NT/2000. Provides properties for reading and writing Bytes, words and doublewords from/to IO ports. New fast block data transfer methods enable to read and write megaBytes of data per second.
Title: File Transfer client and server
Description: Send or recieve files of any size or type between you and a peer. Displays Bytes sent or recieved, return values of send() and recv(), bitrate in KBytes/sec, and time remaining. SendFile and RecvFile functions can easily be added and used in your own code. I tested it ofcourse, a 73 mb self extracting rar archive from South Korea to Massachusetts at 96KB/s arrived fully operational.
