What: /sys/bus/usb/devices/-:./::./operation_mode Date: March 2010 Contact: Bruno Prémont Description: Make it possible to switch the PicoLCD device between LCD (firmware) and bootloader (flasher) operation modes. Reading: returns list of available modes, the active mode being enclosed in brackets ('[' and ']') Writing: causes operation mode switch. Permitted values are the non-active mode names listed when read. Note: when switching mode the current PicoLCD HID device gets disconnected and reconnects after above delay (see attribute operation_mode_delay for its value). What: /sys/bus/usb/devices/-:./::./operation_mode_delay Date: April 2010 Contact: Bruno Prémont Description: Delay PicoLCD waits before restarting in new mode when operation_mode has changed. Reading/Writing: It is expressed in ms and permitted range is 0..30000ms. What: /sys/bus/usb/devices/-:./::./fb_update_rate Date: March 2010 Contact: Bruno Prémont Description: Make it possible to adjust defio refresh rate. Reading: returns list of available refresh rates (expressed in Hz), the active refresh rate being enclosed in brackets ('[' and ']') Writing: accepts new refresh rate expressed in integer Hz within permitted rates. Note: As device can barely do 2 complete refreshes a second it only makes sense to adjust this value if only one or two tiles get changed and it's not appropriate to expect the application to flush its tiny changes explicitly at higher than default rate.
