Video (PAL) geneation using a 4Mhz part Any AVR Paul Robson This is the main routine that generates the video signals and can be added to your programs Hardware SPI handling routines AT90s8515 Andrian Cottle This program reads in 16 bit data on the SPI hardware serial port using the 8515 AVR uC. For this application it is used with the MAX176 Serial 12 bit ADC from Maxim.

The ATMEL Errata Sheet Rev. B for the AT90S8515 describes the "Skip Instructions with
Interrupts" error. An affected application is extremly hard to debug.
Chk8515 is a Win32-console-utility, which analyzes program-code for the AT90S8515 and shows critical code sections, if existing.
The Errata Sheet can be found at here

A few quick instructions about submitting files.
When you  send your submission by e-mail please use as subject "Code for the AVR code Archive" in order to be able to filter out the messages
If possible pack source code, binary and any necessary instructions/schematics  in a single archive.
This will save space and  time for everybody :-).
In the message please include a brief description of the what the program is doing and for which AVR part is designed.
Also include your WWW page if you have one. Full credits are given
