Permitted values are11 the non-active mode names listed when read.12 13 Note: when switching mode the current PicoLCD HID device gets14 disconnected and reconnects after above delay (see attribute15 operation_mode_delay for its value).16 17 18What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/operation_mode_delay19Date: April 201020Contact: Bruno Prémont <bonbons@linux-vserver.org>21Description: Delay PicoLCD waits before restarting in new mode when22 operation_mode has changed.23 24 Reading/Writing: It is expressed in ms and permitted range is25 0..30000ms.26 27 28What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/fb_update_rate29Date: March 201030Contact: Bruno Prémont <bonbons@linux-vserver.org>31Description: Make it possible to adjust defio refresh rate.32 33 Reading: returns list of available refresh rates (expressed in Hz),34 the active refresh rate being enclosed in brackets ('[' and ']')35 36 Writing: accepts new refresh rate expressed in integer Hz37 within permitted rates.38 39 Note: As device can barely do 2 complete refreshes a second40 it only makes sense to adjust this value if only one or two41 tiles get changed and it's not appropriate to expect the application42 to flush its tiny changes explicitly at higher than default rate.43 44
