4 | Description: Make it possible to switch the PicoLCD device between LCD | |
5 | (firmware) and bootloader (flasher) operation modes. | |
6 | ||
7 | Reading: returns list of available modes, the active mode being | |
8 | enclosed in brackets ('[' and ']') | |
9 | ||
10 | Writing: causes operation mode switch. Permitted values are | |
0b5adf92 | 11 | the non-active mode names listed when read. |

13 | Note: when switching mode the current PicoLCD HID device gets | |
0b5adf92 BP |
14 | disconnected and reconnects after above delay (see attribute |
15 | operation_mode_delay for its value). | |

31 | Description: 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 Hz | |
37 | within permitted rates. | |
38 | ||
39 | Note: As device can barely do 2 complete refreshes a second | |
40 | it only makes sense to adjust this value if only one or two | |
41 | tiles get changed and it's not appropriate to expect the application | |
42 | to flush it's tiny changes explicitely at higher than default rate. | |
