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, optionally followed
|
||
|
|
by a delay value expressed in ms.
|
||
|
|
|
||
|
|
Note: when switching mode the current PicoLCD HID device gets
|
||
|
|
disconnected and reconnects after above delay (default value
|
||
|
|
is 5 seconds though this default should not be relied on).
