Page 2 Users can download an unrestricted version of Code Composer Studio™ IDE to write, download, and debug applications on the LAUNCHXL-F28069M board. The debugger is unobtrusive, allowing the user to run an application at full speed with hardware breakpoints and single stepping available while consuming no extra hardware resources.
Page 3 Mini USB-B Cable, 0.5m • Quick Start Guide Revisions The first and only production released of the LAUNCHXL-F28069M in 2014 was revision 1.2. All Revisions: • Resistor R7 in the oscillator circuit is incorrectly placed or should not be installed. This resistor may impact startup time or robustness of the clocking circuit over the full operating range of the MCU or different physical layouts of this circuit.
Page 4 Getting Started With the LAUNCHXL-F28069M Getting Started The first time the LAUNCHXL-F28069M is used, a demo application automatically starts when the board is powered from a USB host. If your board does not start the demo application, try placing S1 in the following positions and resetting the board: UP - UP - DOWN.
Page 5 Composer Studio v6. In the resource explorer, open the controlSUITE folder and then the Development Tools entry and look for the C2000 LaunchPad line item. Expand this item and LAUNCHXL-F28069M, then select the LaunchPad Demo Application. Follow the steps in the main pane of the resource explorer to import, build, debug, and run this application.
Page 6 Serial Connectivity The LAUNCHXL-F28069M has a USB to UART adapter built in. This makes it easy to print debug information back to the host PC even in isolated environments. The F28069M device on this LaunchPad contains two SCI (UART) peripherals, while the LaunchPad has three places these peripherals need to be routed.
Page 7 Connecting a Crystal Although the Piccolo device present on the LAUNCHXL-F28069M has an internal oscillator — and for most applications this is sufficient — the LaunchPad offers a footprint for through-hole HC-49 crystals for users who require a more precise clock. If you wish to use an external crystal, solder the crystal to the Q1 footprint and appropriate load capacitors to the C3 and C4 footprints.
