EK-TM4C1294XL: Refresh weather report in enet_weather example for mcu TM4C1294NCPDT

Hi,

  If you look at the UpdateUART() function you will see the below snippet of code. See the highlighted in red where the terminal window is only refreshed every CYCLE_DELAY of delay. The CYCLE_DELAY is defined in the enet_weather.h file with a value of 3000000. You can play with this value to adjust the refresh you want. Or you can use the timer to create a 60s timeout so the UART will only update the terminal window when the timer timeout. 

//
// Check if we should scroll the cities.
//
if (g_ui32UARTDelay == 0 && g_ui32ShowCities)
{
//
// Clear the terminal. Print the banner and IP place holder.
//
UARTprintf("\033[2J\033[H");
UARTprintf("Ethernet Weather Example\n\n");
UARTprintf("IP: ");

//
// Print the IP address.
//
PrintIPAddress(g_pcIPAddr, ui32IPaddr);
UARTprintf("\n");
UARTprintf("Hit 'ENTER' to exit\n\n");

//
// Print the current city information.
//
UpdateCity(ui32City, true);

//
// 'Updating' banner.
//
UARTprintf("\n__________________________\n\nUpdating:");

if (g_ui32Cycles >= UPDATE_CYCLES)
{
//
// Reset the cities so that they update.
//
for(ui32Idx = 0; ui32Idx < NUM_CITIES; ui32Idx++)
{
ResetCity(ui32Idx);
}

//
// Indicate that we have reset all of the cities.
//
g_ui32Cycles = 0;
}

//
// Reset the delay.
//
g_ui32UARTDelay = CYCLE_DELAY;
