anyone know how to interface ?
can i just direct connect the output from 8051 to 74HC4050 then from tat into SD ?
how i ensure tat the output voltage from 74HC4050 wil drop from 5V to 3.3v at least ?
thank you]]> Tue, 24 Jun 2008 23:29:57 -0700 http://www.8051projects.net/forum-t10306.html http://www.8051projects.net/forum-t10306.html
make sure that 74HC4050 is not bi directional so you might have problem when reading from SD Card.]]> Ajay<contact@nospam.com> Wed, 25 Jun 2008 22:50:31 -0700 http://www.8051projects.net/forum-t10306.html
