Re: SPI/MMC example - anyone got this to work?

2006-03-16 by philips_apps

Tom,

    The source in SPI/MMC app-note has been fixed, retested, and 
updated long time ago, the following week after you pointed out the

    Thanks you very much for your suggestions and active 
participation to improve our products!

Philips app.

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
