Directories and Files
μC/FS is fairly easy to use once you understand which source files are needed to make up a
μC/FS-based application. This chapter will discuss the modules available for μC/FS and how
everything fits together.
Figure 1-01 shows the μC/FS architecture and its relationship with the hardware. Memory
devices may include actual media both removable (SD/MMC, CF cards) and fixed (NAND
flash, NOR flash) as well as any controllers for such devices. Of course, your hardware
would most likely contain other devices such as UARTs (Universal Asynchronous Receiver
Transmitters), ADCs (Analog to Digital Converters) and Ethernet controller(s). Moreover,
your application may include other middleware components like an OS kernel, networking
(TCP/IP) stack or USB stack that may integrate with μC/FS.
A Windows?-based development platform is assumed. The directories and files make
references to typical Windows-type directory structures. However, since μC/FS is available
in source form then it can certainly be used on Unix, Linux or other development platforms.
This, of course, assumes that you are a valid μC/FS licensee in order to obtain the source
code.
The names of the files are shown in upper case to make them ‘stand out’. The file names,
however, are actually lower case.
