I understand that, however when you generate a file with GPIF designer it uses SYNCDELAY; vs fx2lib's SYNCDELAY(); My change alters the calling convention to match Cypress so you don't have to edit the generated file each time. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
