ToolStickUniDC TOOLSTICK UNIVERSITY DAUGHTER CARD USERS GUIDE 1. Handling Recommendations To enable development, the ToolStick Base Adapter and daughter cards are distributed without any protective plastics. To prevent damage to the devices and/or the host PC, consider the following recommendations when using the ToolStick: Never connect or disconnect a daughter card to or from the ToolStick Base Adapter while the Base Adapter is connected to a PC. Always connect and disconnect the ToolStick Base Adapter from the PC by holding the edges of the board. Figure 1. Proper Method of Holding the ToolStick Avoid directly touching any of the other components. Figure 2. Improper Method of Holding the ToolStick Manipulate mechanical devices on the daughter cards, such as potentiometers, with care to prevent the Base Adapter or daughter card from accidentally dislodging from their sockets.

If the daughter card was not purchased as part of a Starter Kit, ToolStick Base Adapters can be purchased separately at www.silabs.com/toolstick. 3. ToolStick Overview The purpose of the ToolStick is to provide a development and demonstration platform for Silicon Laboratories microcontrollers and to demonstrate the Silicon Laboratories software tools, including the Integrated Development Environment (IDE). The ToolStick development platform consists of two components: the ToolStick Base Adapter and a daughter card. The ToolStick Base Adapter provides a USB debug interface and data communications path between a Windows PC and a target microcontroller. The target microcontroller and application circuitry are located on the daughter card. Some daughter cards, such as the ToolStick University Daughter Card, are used as general-purpose development platforms for the target microcontrollers, and some are used to demonstrate a specific feature or application. The ToolStick University Daughter Card features a Silicon Laboratories C8051F020 Mixed-Signal MCU. The external circuitry on the daughter card includes a 22.1184 MHz crystal to enable UART communication, 4 LEDs, 4 push-button switches, an 8-bit DIP switch, a potentiometer, and a reset switch. Ports P0, P1, and P2 of the MCU are accessible via standard headers. A separate header is available for analog input/output that connects external signals to the ADC and comparator inputs, and DAC outputs of the MCU. A small area for prototyping is also provided that can be used to connect additional hardware to the microcontroller and use the daughter card as a development platform. Figure 3 shows the ToolStick University Daughter Card and identifies the various components. 2 Rev. 0.1 Not Recommended for New Designs
