If I ground the channel pins the channels change on the radio fine. Now when I connect the pins to a URI-x gpio1 gpio2 gpio5 and gpio6 It dosent seem to work. I have gpio1=out0 , gpio2=out0, gpio5=out0, gpio6=out0 and when I do a *584=cop,61,GPIO5=1 or *585=cop,61,GPIO5=0 nothing seems to change on the URI, either state I see +5v on the URI. Should it not get pulled to ground? Am I doing something wrong?
