* \defgroup UI User Interface | |
* | |
* Human interface on Xplain-A1: | |
* - RED led close to USB connector is always on after firmware startup | |
* - Led 0 is on when USB line is in IDLE mode, and off in SUSPEND mode | |
* - Led 1 blinks when USB Host have checked and enabled HID and MSC interfaces | |
* - Led 2 is on during read operation | |
* - Led 3 is on during write operation | |
* - Mouse buttons are linked at switches 0 (left), 1 (middle), 2 (right) | |
* - Mouse move are linked at switches 4 (right), 5 (left), 6 (down), 7 (up) | |
* - All switches can be used to wakeup USB Host in remote wakeup mode. | |
