Section 6
Firmware Configuration
6.1 Overview Several files have been implemented to help the software developer to quickly configure
the firmware.
The configuration files “conf_*.h” are all under the conf directory of the firmware pack-
age (see Section 3.1.1). There are four kinds of configuration files:
 Files configuring the Customer MMI layer only
The file conf_mmi.h configures exclusively the Customer MMI layer and more pre-
cisely the MMI applications organized in modules (see Section 3.1.8).
 Files configuring both the Customer MMI and the Atmel system layers
These files are the ones that configure the source code of custom MMI peripherals:
– conf_kbd.h: configures both the keyboard driver of the system firmware system
and the key affectation dedicated to the MMI modules using the keyboard.
– conf_lcd.h: configures the lcd driver of the system firmware system, the API of the
LCD driver and the mmi_manager module.
– conf_audio.h: configures both the custom audio firmware module for external
DAC implementation and the audio part of the player module.
– conf_update.h: configures both the application MMI update and the update
firmware module.
 Files configuring the Atmel system layer only
– conf_access.h: enables the implementation of memory access interfaces only
required in your custom application. It mainly configures the source code files of
the control access firmware module.
– conf_clock.h: configures the oscillator frequency which depends all the lib_mcu
drivers: clock, lcd, timer, memory controllers, …
– conf_explorer.h: configures the file_system module and the playlist module.
– conf_nf.h: configures the nand_flash memory module and the Nand Flash
controller driver.
– conf_power.h: configures the power module, the audio module and the API of the
lcd driver.
– conf_scheduler.h: configures the scheduling of the system task.
– conf_usb.h: configures the USB controller driver (see Section 3.1.5), the USB
module and the SCSI decoder module.
