EZ-USB Firmware Frameworks

5.2

Building FrameWorks

The framework is written using the Keil uVision2 Compiler. It is tested only with these tools. Because
the source uses several Keil C extensions, compatibility with other compilers is not guaranteed.

For your custom device firmware, you can either start with one of the firmware examples or start with
the "clean" frameworks code. This code is located in the

<Installed_directory>\<ver-

sion>\Target\fw

directory. The sub-directory is chip dependent. For FX2LP and FX1, the firm-

ware is located in the "LP" sub-directory. Before editing the firmware, create a new directory for your
project and copy the various frameworks source files into it.

After starting the Windows Command Prompt, run

setenv.bat

(located in the

Bin

directory) to set up

the build environment. This batch file assumes that you have installed the DVK and Keil tools in the
default directories.

The following table lists and describes the main files in the frameworks:

Table 5-1. Files in Firmware Frameworks

File Name

Description

FW.C

This is the main frameworks source file. It contains main(), the task dispatcher, and the
SETUP command handler. For most firmware projects, there is no need to modify this file

PERIPH.C

This source file contains initialization and task dispatch functions that are called from fw.c.
This is where you customize the frameworks for your specific device. This file also con-
tains stub interrupt service routine (ISRs) functions for all of the USB (INT2) and GPIF
(INT4) interrupts

DSCR.A51

Assembly file that contains your device's custom descriptors

FX2.H/LP.H

Head file containing common EZ-USB constants, macros, data types, and library function
prototypes

FX2REGS.H/
LPREGS.H

EZ-USB register declarations and bit mask constants

SYNCDLY.H/
FX2SDLY.H

Contains the synchronization delay macro.

EZUSB.LIB

EZ-USB Library object code. See

EZ-USB Library on page 41

for more details

USBJMPTB.OBJ Object code that contains the ISR jump table for USB and GPIF interrupts

BUILD.BAT

Batch file for compiling/linking the firmware using the Keil command line tools

FW.UV2

Keil uVision2 project file for compiling/linking the firmware
