I find the cystal is > 25MHz on the schematic. Look at the schematic for the TINIm400 and you will see a 14.7456MHz crystal. This is the crystal shipped on the TINIm400. The TINIm390 uses an 18.432MHz crystal as shipped. -- -- Bryan Armstrong bryan.armstrong-6tN4nzCoH/[email protected] _______________________________________________ TINI mailing list TINI-6tN4nzCoH/[email protected] To UNSUBSCRIBE, edit your profile, or see list archives: http://lists.dalsemi.com/mailman/listinfo/tini
