BoosterPacks www.ti.com – For a complete list of BoosterPacks, see the TI MCU LaunchPad web page: http://www.ti.com/launchpad 1.4 BoosterPacks The Connected LaunchPad provides an easy and inexpensive way to develop applications with the TM4C1294NCPDTI microcontroller. BoosterPacks are add-on boards that follow a pin-out standard created by Texas Instruments.
Chapter 2 SPMU365A – March 2014 – Revised March 2014 Hardware Description The Connected LaunchPad includes a TM4C1294NCPDTI microcontroller with an integrated 10/100 Ethernet MAC and PHY. This advanced ARM® Cortex™ M4F MCU has a wide range of peripherals that are made available to users via the on-board accessories and the BoosterPack connectors. This chapter explains how those peripherals operate and interface to the microcontroller.
Functional Description www.ti.com 2.1.2 Ethernet Connectivity The Connected LaunchPad is designed to connect directly to an Ethernet network using RJ45 style connectors. The microcontroller contains a fully integrated Ethernet MAC and PHY. This integration creates a simple, elegant and cost-saving Ethernet circuit design. Example code is available for both the uIP and LwIP TCP/IP protocol stacks. The embedded Ethernet on this device can be programmed to act as an HTTP server, client or both.
Functional Description www.ti.com 2.1.6 BoosterPacks and Headers 2.1.6.1 BoosterPack 1 The Connected LaunchPad features two fully independent BoosterPack XL connectors. BoosterPack 1, located around the ICDI portion of the board, is fully compliant with the BoosterPack standard with the single exception of GPIO pin PA6 (X8-16), which does not provide analog capability. PA6 is located near the bottom of the inner left BoosterPack XL header.
Functional Description www.ti.com Table 2-1.
Functional Description www.ti.com 2.1.6.2 BoosterPack 2 The second BoosterPack XL interface is located near the middle of the board. This interface is fully compliant with the BoosterPack standard, and adds features not covered by the BoosterPack standard that enable operation with additional BoosterPacks. An additional analog signal is provided on the outer left header (X6-9). This signal can be used to monitor the touch panel on the popular Kentec EB-LM4F120-L35 BoosterPack.
Functional Description www.ti.com Table 2-2.
Functional Description www.ti.com 2.1.6.3 Breadboard Connection The breadboard adapter section of the board is a set of 98 holes on a 0.1 inch grid. Properly combined with a pair of right angle headers, the entire Connected LaunchPad can be plugged directly into a standard 300 mil (0.3 inch) wide solder-less breadboard. The right angle headers and breadboard are not provided with this kit.

Power Management www.ti.com 2.1.6.4 Other Headers and Jumpers JP1 is provided to select the power input source for the Connected LaunchPad. The top position is for BoosterPack power; this position also disconnects both USB voltages from the board’s primary 5-volt input. In the top position, the TPS2052B does not limit current so additional care should be exercised. The middle position draws power from the USB connector on the left side of the board near the Ethernet jack.
Power Management www.ti.com 2.2.2 Low Power Modes The Connected LaunchPad demonstrates several low power microcontroller modes. In run mode, the microcontroller can be clocked from several sources such as the internal precision oscillator or an external crystal oscillator. Either of these sources can then optionally drive an internal PLL to increase the effective frequency of the system up to 120 MHz. In this way, the run mode clock speed can be used to manage run mode current consumption.
Debug Interface www.ti.com 2.3.2 External Debugger The connector U6 is provided for the attachment of an external debug adapter such as the IAR J-Link or Keil ULINK. This connector follows the ARM standard 10-pin JTAG pinout. This interface can use either JTAG or SWD if supported by the external debug adapter. 2.3.3 Virtual COM Port When plugged into a USB host, the ICDI enumerates as both a debugger and a virtual COM port.
Chapter 3 SPMU365A – March 2014 – Revised March 2014 Software Development This chapter provides general information on software development as well as instructions for flash memory programming. 3.1 Software Description The TivaWare software provides drivers for all of the peripheral devices supplied in the design. The Tiva C Series Peripheral Driver Library is used to operate the on-chip peripherals as part of TivaWare.
Programming the Connected LaunchPad www.ti.com 3.4 Programming the Connected LaunchPad The Connected LaunchPad software package includes pre-built binaries for each of the example applications. If you installed the TivaWare™ software to the default installation path of C:\ti\TivaWare_C_Series_, you can find the example applications in C:\ti\TivaWare_C_Series\examples\boards\ek-tm4c129xl.
