View source for GamePad/LVC

'''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.

= Memory Map =
This is the memory map setup for the MMU. All virtual and physical addresses are the same, so there is no address translation being used.
