3.2 Directories
Logical
Organization
This purpose of this view is to show the logical links between the directories.
These source file directories can be grouped into two firmware parts:
– the customer MMI firmware
– the Atmel system firmware
The customer MMI firmware is the code source you have to develop and customize from
the software platform delivered with this package. Indeed, this layer is dedicated to inter-
face the user with the high-level services provided by the Atmel core firmware and the
AT85C51SNDA chip. See Firmware Architecture Section 5.
The Atmel system firmware is the code source you should not modify since this layer
has been designed to provide full and high-performance services from a low cost chip.
Only the configuration files are to set in order to configure this layer to your application
requirements. See Firmware Configuration Section 6.
