| 4 | Description: Make it possible to switch the PicoLCD device between LCD |
| 5 | (firmware) and bootloader (flasher) operation modes. |

| 8 | enclosed in brackets ('[' and ']') |

| 10 | Writing: causes operation mode switch. Permitted values are |
| Bruno Prémont | 0b5adf9 | 2010-04-25 21:29:16 +0200 | [diff] [blame] | 11 | the non-active mode names listed when read. |
| Bruno Prémont | 236db47 | 2010-03-30 22:33:50 +0200 | [diff] [blame] | 12 | |
| 13 | Note: when switching mode the current PicoLCD HID device gets |

| 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 |
| Kees Cook | 0855965 | 2016-04-26 16:41:21 -0700 | [diff] [blame] | 42 | to flush its tiny changes explicitly at higher than default rate. |
