The user’s program is then responsible for sending and receiving data through the UART as necessary. Configure the baud rate, word length, stop bit, and parity.Configure the function of the RX and TX pins.In general, the user must initialize and configure the UART as well as the GPIO pins for RX0 and TX0.
The ICDI virtual serial port is hardwired to the RX and TX pins of UART0 of the target TM4C123G processor on the LaunchPad. Configuring the target processor’s serial port If you haven’t installed them already, you can download the drivers and read the installations instructions here. There are three Windows drivers that must be installed before you can fully use the ICDI interface on the LaunchPad. We’ll be using the serial port under Windows 7 and communicating with a generic terminal program in this example. This post guides you through the process of using the virtual serial communications port that is available within the In-Circuit Debug Interface (ICDI) on the Texas Instruments EC-TM4C123GXL LaunchPad board.
