One possibility might be to connect each encoder to the preceding amp-enable: So, GPIO-0 enables encoder 0, when encoder 0 is inited then amp-enable 0 is set high. Amp-enable 0 enables encoder 1… amp-enable 1 enables encoder 2... -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
