Lock

When locked, the LYNX's drive function is disabled. The LYNX can be locked either through GPIO or via the IOT protocol.

The lock feature is optional and not available in all mods of LYNX. To verify if your mod supports locking, check the terminal output after boot. Lock support is indicated by either - Lock or - Lock lite messages.

• Lock lite indicates support for IOT-only locking with freewheeling mode
• Lock indicates full support for both GPIO and IOT locking

GPIO Lock

The controller can be locked using a connected button or switch. The lock input (in_lock) must be mapped to GPIO via input mapping.

Lock activation can be configured through the /lock/lockopts parameter to respond to short press, long press, or level (switch).

IOT Lock

The controller supports locking through the IOT protocol via the lock command.

This method is compatible with the siliXcon VDS display.

tip

To use lock functionality with the display, enable lock at startup. Otherwise, the device will initialize in an unlocked state.

Parameters

info

All parameters are located in the /lock folder.

Lock lite only includes the lockopts parameter. Additional parameters are available with full lock support.

lockopts

This bitwise parameter configures lock behavior.

Value:or click on a row to toggle.

Bit	Description
0	Activate lock by short press
1	Activate lock by long press
2	Activate lock by level (switch)
3	Start controller in locked state (lock device at startup)

tip

Enable lock at startup when using the display interface.

locktim [s]

Sets automatic locking timeout. The timer only runs when accelerator and brake are inactive.

lock_lpf

For non-freewheeling lockmode, lock activation uses the low-pass filter.

lockmode

Sets the controller's behavior when locked. Default is freewheeling mode.

Value	Description
0	Freewheeling mode
4	Voltage brake mode
8	Brake mode
15	Phase short brake mode

tip

lockmode corresponds to driver mode, but only the above values are permitted.
