2 Installation of Edde Flex CAN Booster Pack for TI TIVA C

Installation of the Edde Flex CAN booster pack on the EK-TM4C123GXL Launchpad is straight forward. Note that for proper alignment the silkscreen text on the booster pack is upside down in relationship to the silkscreen text on the LaunchPad. for the proper orientation, see Figure 2-1.

With switches 1 and 2 in the “on” position, PE4 and PE5 will be connected to the transmit and receive pins of the booster pack CAN transceiver. Switch 3 in the "on" position connects a 120 Ω termination resistor between CAN0H and CAN0L.

With the exception of the internal loopback example, all examples require a working CAN network. A simple CAN network can be constructed using two EK-TM4C123GXL each with an Edde Flex booster pack as shown in Figure 2-2. Note that there are three connections between the two systems, CAN0H, CAN0L and GND.
