C8051F04x-DK 5. Example Source Code Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F04x” 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 Controller Area Network (CAN) application example is also included with the C8051F04x development kit. 5.1. Register Definition Files

C8051F04x-DK 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 b

C8051F04x-DK You may run the example with the Debug Adapter connected to view CAN registers, and CAN message objects in CAN RAM. While connected to one target board, run the code. Depress the RESET button on the other target board. You may use debug and view features of the Silicon Laboratories IDE and on-chip debug logic. To view the CAN SFRs, click View →Debug Windows →SFRs →CAN0. To view message objects in CAN RAM, click View →Debug Windows →CAN0 Message Registers. To view SFRs and message re

C8051F04x-DK 6. Target Board The C8051F04x Development Kit includes a target board with a C8051F040 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 3 for the locations of the various I/O connectors. P1 Power connector (accepts input from 7 to 15 VDC unregulated power adapter) J1 Connects SW2 to P3.7 pin J3 Connects LED D3 to P1.6 pin J4 JTAG connector

C8051F04x-DK 6.1. System Clock Sources The C8051F040 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 3.0625 MHz (±2%) by default but may be configured by software to operate at other frequencies. Therefore, in many applications an external oscillator is not required. However, an external 22.1184 MHz crystal is installed on the target b

C8051F04x-DK 6.4. Serial Interface (J5) A RS232 transceiver circuit and DB-9 (J5) connector are provided on the target board to facilitate serial connec- tions to UART0 of the C8051F040. The TX, RX, RTS and CTS signals of UART0 may be connected to the DB-9 connector and transceiver by installing shorting blocks on headers J6, J8, J9 and J10. J6 - Install shorting block to connect UART0 TX (P0.0) to transceiver. J9 - Install shorting block to connect UART0 RX (P0.1) to transceiver. J8 - Install

C8051F04x-DK 6.6. Controller Area Network (CAN) Interface (J25) A DB-9 (J25) connector is provided to facilitate serial connections to the CAN interface on the C8051040. In addi- tion, when a shorting block is installed on header J7, writing a logic 'high' to port pin P4.2 will place the CAN trans- ceiver in low-current standby mode. Also, resistor R12 may be replaced with a higher value to control the slew rate of the CAN_H and CAN_L signals. See the TI SN65HVD230 data sheet for further inform

C8051F04x-DK 6.9. Expansion I/O Connector (J24) The 96-pin expansion I/O connector J24 is used to connect daughter boards to the main target board. J24 provides access to many C8051F040 signal pins. Pins for +3 V, digital ground, analog ground and the unregulated power supply (VUNREG) are also available. The VUNREG pin is connected directly to the unregulated +V pin of the P1 power connector. See Table 7 for a complete list of pins available at J24. The J24 socket connector is manufactured by H
