2. Hardware Setup using an EC2 Serial Adapter

Connect the target board to a PC running the Silicon Laboratories IDE via the Serial Adapter as shown in Figure 1.

1. Connect one end of the RS232 serial cable to a serial (COM) port on the PC.

2. Connect the other end of the RS232 serial cable to the DB-9 connector on the Serial Adapter.

3. Connect the Serial Adapter to the DEBUG connector on the target board using the 10-pin ribbon cable.

4. Connect the AC/DC power adapter to power jack P1 on the target board.

Notes:

•Use the Reset button in the IDE to reset the target when connected using an EC2 Serial Adapter.

• Remove power from the target board and the EC2 before removing the ribbon cable from the target board.

Connecting or disconnecting the cable when the devices have power can damage the device and/or the EC2.

C8051F34x-DK 5.2. 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). 5.3. 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.

C8051F34x-DK 5.4.2. Building and Downloading the Program for Debugging 1. Once all source files have been added to the target build, build the project by clicking on the Build/Make Project button in the toolbar or selecting Project->Build/Make Project from the menu. Note: After the project has been built the first time, the Build/Make Project command will only build the files that have been changed since the previous build.

C8051F34x-DK 6. Example Source Code Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F34x” directory during IDE installation. These files may be used as a template for code development. Example applications include a blinking LED example which configures the green LED on the target board to blink at a fixed rate. A Universal Serial Bus (USB) application example is also included with the C8051F34x development kit. 6.1.

C8051F34x-DK 6.3. Universal Serial Bus (USB) Application Example The included USB application example requires Windows 98SE/2000/XP operating system. This example consists of three parts: firmware running on the C8051F340 device, a USB device driver running on the host PC, and a host application. The host application communicates with the C8051F340 via USB, allowing the user to view and to change the state of several I/O peripherals on the C8051F340 target board.

C8051F34x-DK 6.3.2. Installing the USB Driver 1. Connect the USB cable between the host computer and the C8051F340 target board, as shown in Figure 3. See Figure 4 on page 8 for the location of the USB connector. 2. At this point, Windows should notify you it has found new hardware and prompt you with a Found New Hardware wizard. Press the Next button. 3. Select Search for a suitable driver for my device (recommended) and press the Next button. 4.

C8051F34x-DK 7. Target Board The C8051F34x Development Kit includes a target board with a C8051F340 device pre-installed for evaluation and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using the target board. Refer to Figure 4 for the locations of the various I/O connectors.

C8051F34x-DK 7.1. System Clock Sources The C8051F340 device installed on the target board features a calibrated programmable internal oscillator which is enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of 1.5 MHz (±1.5%) by default but may be configured by software to operate at other frequencies. Therefore, in many applications an external oscillator is not required.

C8051F34x-DK 8. EC2 Serial Adapter The Serial Adapter provides the interface between the PC’s RS232 serial port and the C8051F34x’s in-system debug/programming circuitry. The Serial Adapter connects to the C8051F340 C2 debug interface on the target board using the 10-pin connector on the Serial Adapter labeled “DEBUG”, see Figure 5. (The Serial Adapter supports both Silicon Laboratories JTAG and C2 debug interfaces.).

C8051F34x-DK 9. USB Debug Adapter The USB Debug Adapter provides the interface between the PC’s USB port and the C8051F34x’s in-system debug/programming circuitry. The attached 10-pin DEBUG ribbon cable connects the adapter to the target board and the target device’s debug interface signals. (The USB Debug Adapter supports both Silicon Laboratories JTAG and C2 debug interfaces.) Power is provided to the adapter from the USB connection to the PC.
