Simplicity Studio greatly reduces development time and complexity with Silicon Labs EFM32 and 8051 MCU products by providing a high-powered IDE, tools for hardware configuration, and links to helpful resources, all in one place.
Once Simplicity Studio is installed, the application itself can be used to install additional software and documentation components to aid in the development and evaluation process.
The following Simplicity Studio components are required for the C8051F310 Development Kit: 8051 Products Part Support Simplicity Developer Platform Download and install Simplicity Studio from www.silabs.com/8bit-software or www.silabs.com/simplicity-studio .

Each project has its own source files, target configuration, SDK configuration, and build configurations such as the
build configurations. The IDE can be used to manage multiple projects in a collection called a workspace. Workspace settings are applied globally to all projects within the workspace. This can include settings such as key bindings, window preferences, and code style and formatting options. Project actions, such as build and debug are context sensitive. For example, the user must select a project in the
view in order to build that project.

The C8051F31x Development Kit includes a target board with a C8051F310 device pre-installed for evaluation and preliminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping

The C8051F310 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, if you wish to operate the C8051F310 device at a fre quency not available with the internal oscillator, an external crystal may be used. Refer to the C8051F31x data sheet for more information on configuring the system clock source.
The target board is designed to facilitate the installation of an external crystal. Remove shorting blocks at headers J9 and J10 and install the crystal at the pads marked Y1. Install a 10 M resistor at R9 and install capacitors at C14 and C15 using values appropriate for the crystal you select. Refer to the C8051F31x data sheet for more infor mation on the use of external oscillators.
Two switches are provided on the target board. Switch SW1 is connected to the RESET pin of the C8051F310.
Pressing SW1 puts the device into its hardware-reset state. Switch SW2 is connected to the C8051F310’s general purpose I/O (GPIO) pin through headers. Pressing SW2 generates a logic low signal on the port pin. Remove the shorting block from the header to disconnect SW2 from the port pins. The port pin signal is also routed to a pin on
Two LEDs are also provided on the target board. The red LED labeled PWR is used to indicate a power connection to the target board. The green LED labeled with a port pin name is connected to the C8051F310’s GPIO pin through headers. Remove the shorting block from the header to disconnect the LED from the port pin. The port pin

A RS232 transceiver circuit and DB-9 (J5) connector are provided on the target board to facilitate serial connec tions to UART0 of the C8051F310. The TX, RX, RTS and CTS signals of UART0 may be connected to the DB-9 connector and transceiver by installing shorting blocks on header J3.
J3[5–6]- Install shorting block to connect UART0 TX (P0.4) to transceiver.

The USB Debug Adapter includes a connection to provide power to the target board. This connection is routed from J4 to J8. Place a shorting block at header J8[2–3] to power the board directly from an ac/dc power adapter. Place a shorting block at header J8[1–2] to power the board from the USB Debug Adapter. Please note that the second option is not supported with either the EC1 or EC2 Serial Adapters.
The C8051F310 target board features a low-pass filter that may be connected to port pin P2.4. Install a shorting block on J7[1–2] to connect the P2.4 pin of the target device to the low-pass filter input. The output of the low-pass filter is routed to the PWM signal at J1. The C8051F310 may be programmed to generate a PWM (Pulse-Width Modulated) waveform which is then input to the low-pass filter to implement a user-controlled PWM digital-to-ana log converter. Refer to Applications Note “AN107: Implementing 16-Bit PWM Using the PCA” in the “
” directory on the CD-ROM for a discussion on generating a programmable dc voltage level with a PWM waveform and low-pass filter.
