2. Hardware Setup using a USB Debug Adapter

The target board is connected to a PC running the Silicon Laboratories IDE via the USB Debug Adapter as shown

in Figure 1.

Notes:

Connect the USB Debug Adapter to the JTAG connector on the target board with the 10-pin ribbon cable.

Connect one end of the USB cable to the USB connector on the USB Debug Adapter.

Connect the other end of the USB cable to a USB Port on the PC.

Connect the ac/dc power adapter to power jack P1 on the target board.

• Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter.

• Remove power from the target board and the USB Debug Adapter before connecting or disconnecting the

ribbon cable from the target board. Connecting or disconnecting the cable when the devices have power can

damage the device and/or the USB Debug Adapter.

3. Software Setup

The included CD-ROM contains the Silicon Laboratories Integrated Development Environment (IDE), Keil software

8051 tools and additional documentation. Insert the CD-ROM into your PC’s CD-ROM drive. An installer will auto-

matically launch, allowing you to install the IDE software or read documentation by clicking buttons on the Installa-

tion Panel. If the installer does not automatically start when you insert the CD-ROM, run

autorun.exe

found in the

root directory of the CD-ROM. Refer to the

readme.txt

file on the CD-ROM for the latest information regarding

known IDE problems and restrictions.

4. Silicon Laboratories Integrated Development Environment

The Silicon Laboratories IDE integrates a source-code editor, source-level debugger and in-system Flash program-

mer. The use of third-party compilers and assemblers is also supported. This development kit includes the Keil

Software A51 macro assembler, BL51 linker and evaluation version C51 ‘C’ compiler. These tools can be used

from within the Silicon Laboratories IDE.

4.1. System Requirements

The Silicon Laboratories IDE requirements:

• Pentium-class host PC running Microsoft Windows 98SE or later.

• One available COM or USB port.

• 64 MB RAM and 40 MB free HD space recommended.

4.2. Assembler and Linker

A full-version Keil A51 macro assembler and BL51 banking linker are included with the development kit and are

installed during IDE installation. The complete assembler and linker reference manual can be found under the

Help

menu in the IDE or in the “SiLabs\MCU\hlp” directory (A51.pdf).

4.3. Evaluation C51 ‘C’ Compiler

An evaluation version of the Keil C51 ‘C’ compiler is included with the development kit and is installed during IDE

installation. The evaluation version of the C51 compiler is the same as the full professional version except code

size is limited to 4 kB and the floating point library is not included. The C51 compiler reference manual can be

found under the

Help

menu in the IDE or in the “SiLabs\MCU\hlp” directory (C51.pdf).

4.4. Using the Keil Software 8051 Tools with the Silicon Laboratories IDE

To perform source-level debugging with the IDE, you must configure the Keil 8051 tools to generate an absolute

object file in the OMF-51 format with object extensions and debug records enabled. You may build the OMF-51

absolute object file by calling the Keil 8051 tools at the command line (e.g. batch file or make file) or by using the

project manager built into the IDE. The default configuration when using the Silicon Laboratories IDE project

manager enables object extension and debug record generation. Refer to Applications Note

AN104 - Integrating

Keil 8051 Tools Into the Silicon Laboratories IDE

in the “SiLabs\MCU\Documentation\Appnotes” directory on the

CD-ROM for additional information on using the Keil 8051 tools with the Silicon Laboratories IDE.

To build an absolute object file using the Silicon Laboratories IDE project manager, you must first create a project. A

project consists of a set of files, IDE configuration, debug views, and a target build configuration (list of files and tool

configurations used as input to the assembler, compiler, and linker when building an output object file).

The following sections illustrate the steps necessary to manually create a project with one or more source files, build

a program and download the program to the target in preparation for debugging. (The IDE will automatically create a

single-file project using the currently open and active source file if you select

Build/Make Project

before a project is

defined.)

5.3. Controller Area Network (CAN) Application Example

Configuration and use of the CAN controller is documented in the Bosch CAN User’s Guide, located in the “Documen-

tation”

directory on the CD-ROM. Accessing the CAN controller (i.e., accessing the CAN RAM, CAN registers, and

moving data to and from the CAN controller) is documented in Silicon Laboratories’ C8051F04x data sheet.

An example CAN application is included in the “Examples\C8051F04x” directory. Each C8051F040 target board fea-

tures a push button (labeled P3.7) and a LED (labeled P1.6). After the two target boards are connected together via

the provided CAN bus physical layer (i.e. cable, connectors, and CAN transceiver), the example application sends

CAN messages between the two target boards containing the state of the push buttons. In this example, each CAN

controller has two of the 32 message objects configured: one to send a control signal based on the state of its target

board push button, and one to receive a control signal from the other target to see if it should turn on/off its own LED.

When a target board receives a message that the push button on the other target board is depressed, it lights its own

LED. When a target board receives a message that the push button on the other target board is not depressed, it

turns off its own LED. In this way, the push button on one target board controls the LED on the other target board as

a virtual control link via a CAN bus.

5.3.1. Setting-up the Application

1. Connect the target boards together at the CAN DB-9 connectors using the CAN cable provided in the

development kit, as shown in Figure 2 on page 6. The correct cable has a male connector on both ends.

Take care not to connect the CAN cable to the RS232 DB-9 connector. See Figure 3 on page 7 for the

location of the CAN DB-9 connector.

2. Compile and link the can1.c example located in the “Examples\C8051F04x” directory on the CD-ROM.

Choose one of the target boards as Target Board #1. Connect to Target Board #1 and download the can1

project to the C8051F040, following the steps outlined in Section 4.4 on page 2. Once downloaded, close

this project in the IDE and disconnect the Debug Adapter from Target Board #1.

3. Connect the Debug Adapter to the other target board, Target Board #2. Open a new project in the IDE and

load can2.c into the C8051F040 device, just as was done in step 2 for Target Board #1. Take care not to

load can1.c into both devices. Disconnect the Debug Adapter from this board.

You should now have can1.c loaded into Target Board #1, and can2.c loaded into Target Board #2. The CAN cable

should be connected to both boards at the CAN DB-9 connectors.

5.3.2. Running the Application

1. Start the application by resetting the device on each target board. Do this by depressing the RESET push

button on each target board. As can1.c executes on Target Board #1, and can2.c runs on Target Board #2,

the devices are now nodes on a CAN bus.

2. Pressing the P3.7 push button on Target Board #1 will light the LED on Target Board #2. Likewise, when

the push button on Target Board #1 is released, the LED on Target Board #2 will turn off. This will work on

either target board.

Once this example is running, you have established a simple CAN network with two nodes. When one C8051F040

device senses the push button on its target board is pressed, it sends a “0x11” in the first byte of a CAN message

data field. When the button is released, the first byte of the CAN message data field is “0x00”. When a C8051F040

device receives a message, it checks whether this byte has a value of “0x11” or “0x00”. When the byte is “0x11”,

the device turns on its LED by setting P1.6 high. When the byte is “0x00”, the device turns off its LED by setting

P1.6 low.
