GamePad/LVC

LVC is the firmware running on the 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

• drvaamp - Audio amplifier
• drvacapt - Audio capture
• drvaout - Audio output
• drvblit - Screen surface blit
• drvcmos - Video camera
• drvdma - DMA handling
• drvevt - Events and callbacks
• drvfifo
• drvflash - SPI flash
• drvgpio - GPIO management
• drvi2c - I²C
• drvir - InfraRed
• drvldc - LCD
• drvmem - Memory allocation and stats
• drvspi - SPI
• drvstc - System Time Clock (This driver is only named in the factory app, but its function are still in the latest firmware).
• drvuic - Communication with the UIC
• drvvcapt - Video capture
• drvvout - Video output
• drvwifi - Wi-Fi networking

Services

• sc_astrm - Audio streaming protocol

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.

Start Address	End Address	Size	Description
0x00000000	0x00157FFF	0x158000	Cached memory
0x00158000	0x003F7FFF	0x2A0000	Uncached memory
0x003F8000	0x003FFFFF	0x8000	MMU translation table
