3.1.8.1 BoosterPack Sites

The F28002x LaunchPad features two fully independent BoosterPack XL connectors. BoosterPack site #1, located above the F28002x MCU and below the XDS110 debugger, is compliant with the BoosterPack standard. BoosterPack site #2, located under the F28002x MCU, is compliant with the BoosterPack standard as well, but with less signals available on the pins. To expand the functions available to the user on this LaunchPad, some signals are also routed to alternate locations on the board. These alternate routes can be selected by manipulating the onboard switches or by adding or removing 0 Ω resistors. This is described in Section 3.3.

The GPIO pin numbers as well as the BoosterPack compliant features can be viewed in the LAUNCHXL-F280025C Quick Start Guide (SPRUIW5). Each GPIO has multiple functions available through the F28002x device's GPIO mux. Some specific functions have been listed in the Quick Start Guide; the full GPIO mux table can be found in the TMS320F28002x microcontrollers datasheet.

All of the analog signals (denoted ADCIN) of the F28002x MCU are routed to the J1/J3 and J5/J7 BoosterPack headers on the left side of the board. Close to the respective BoosterPack header each ADC input signal has component pads for a series resistor and parallel capacitor to create an RC filter. By default a 0 ohm resistor is populated and the capacitor is left un-populated. Users may wish to populate these components with specific values in order to filter out noise arriving at the device's ADC input.
