Ti-RTOS UART1初始化：请问将怎么tiva c launchpad的echo事例修改为使用uart1

我需要将tiva c launchpad的echo事例修改为使用uart1，请告诉我修改哪里。。。？
Void EK_TM4C123GXL_initUART()

/* Enable and configure the peripherals used by the uart. */
SysCtlPeripheralEnable(SYSCTL_PERIPH_UART0);
GPIOPinConfigure(GPIO_PA0_U0RX);
GPIOPinConfigure(GPIO_PA1_U0TX);
GPIOPinTypeUART(GPIO_PORTA_BASE, GPIO_PIN_0 | GPIO_PIN_1);
/* Initialize the UART driver */
UART_init();
]

UART_Params_init(&uartParams);
uartParams.writeDataMode = UART_DATA_BINARY;
uartParams.readDataMode = UART_DATA_BINARY;
uartParams.readReturnMode = UART_RETURN_FULL;
uartParams.readEcho = UART_ECHO_OFF;
uartParams.baudRate = 115200;
uart = UART_open(Board_UART0, &uartParams);
