AT91 SAM7 Basic USB Project The goal of this demonstration project is to demonstrate how to use the AT91 ARM-Based Software Package. This project runs a test of the AT91SAM7Sxx device and his corresponding Evaluation Kit, the AT91SAM7Sxx-EK. This project implements a USB communication using the on-chip USB device with a PC application. Install Please copy atmusb6124.inf in the following windows directory C:\WINxx\inf directory and atmusb6124.sys in the following windows directory C:\WINxx\system32\drivers directory. When the USB device is connected for the first time, the PC host asks for a driver installation file (.inf file). atmusb6124.sys driver will be associated to this device. The BasicUSB_6124.exe PC application is then ready to communicate: C:\ BasicUSB_6124.exe This will transmit buffer every second to each connected device. Quick description This device uses 3 pipes associated with physical endpoints: ， EP0 Control endpoint ， EP1 Bulk IN endpoint ， EP2 Bulk Out endpoint During the initialization, ， The peripheral clock must be enabled for the USB device and the 48MHz PLL USB clock. ， Pipe objects are then initialized and the dispatch routine is associated with the control pipe ， The pull-up on USB DP line is finally activated Once the device is plugged and the enumeration phase completed, the application reads data from the USB host and sends back a packet through the DBGU. After ten seconds with any connected device found, the PC application stops sending packet.
