we are evaluating data communication through USB to GPIO,
the 7688 Duo has only 3 GPIOs from MPU, others from MCU,
but 7688 (not Duo) all GPIOs are from MPU,
does it mean we can get maximum data rate from non Duo version ?
(if it is not dominate by USB 2.0)
what is the maximum data rate ?
Is there any existing example for this application ?
