'''LVC''' is the firmware running on the [[GamePad/DRC|DRC-WUP]]. It uses the eForce uC3/Standard operating system, which follows the μITRON4.0 Specification.
= Firmware =
The firmware is split up into several drivers, services and managers.
== Application ==
After starting uC3 the APLMAIN task is created, which sets up the different drivers, services and managers.
== Drivers ==
