Internet of Things Quickstart (qs_iot)

+//! +//! +//! This application records various information about user activity on the +//! board, and periodically reports it to a cloud server managed by Exosite. In +//! order to use all of the features of this application, you will need to have +//! an account with Exosite, and make sure that the device you are using is +//! registered to your Exosite profile with its original MAC address from the +//! factory. +//! +//! If you do not yet have an Exosite account, you can create one at +//! http://ti.exosite.com. The web interface there will help guide you through +//! the account creation process. There is also information in the Quickstart +//! document that is shipped along with the EK-TM4C1294XL evaluation kit. +//! +//! This application uses a command-line based interface through a virtual COM +//! port on UART 0, with the settings 115,200-8-N-1. This application also +//! requires a wired Ethernet connection with internet access to perform +//! cloud-connected activities. +//! +//! Once the application is running you should be able to see program output +//! over the virtual COM port, and interact with the command-line. The command +//! line will allow you to see the information being sent to and from Exosite's +//! servers, change the state of LEDs, and play a game of tic-tac-toe. If you +//! have internet connectivity issues, need to find your MAC address, or need +//! to re-activate your EK-TM4C1294XL board with Exosite, the command line +//! interface also has options to support these operations. Type +//! 'help' at the command prompt to see a list of available commands. +//! +//! If your local internet connection requires the use of a proxy server, you +//! will need to enter a command over the virtual COM port terminal before the +//! device will be able to connect to Exosite. When prompted by the +//! application, type 'setproxy help' for information on how to configure the +//! proxy. Alternatively, you may uncomment the define statements below for +//! "CUSTOM_PROXY" settings, fill in the correct information for your local +//! http proxy server, and recompile this example. This will permanently set +//! your proxy as the default connection point. +//! +// +//***************************************************************************** + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ +} +#endif + +//***************************************************************************** +// +// Global macro definitions. +// +//***************************************************************************** +#define MAX_SYNC_RETRIES 10 + +// #define CUSTOM_PROXY +// #define PROXY_ADDRESS "your.proxy.address" +// #define PROXY_PORT 80 + +//***************************************************************************** +// +// Global variables that will be linked to Exosite. +// +//***************************************************************************** +uint32_t g_ui32SW1Presses = 0;

In +order to use all of the features of this application, you will need to have +an account with Exosite, and make sure that the device you are using is +registered to your Exosite profile with its original MAC address from the +factory. + +If you do not yet have an Exosite account, you can create one at +http://ti.exosite.com. The web interface there will help guide you through +the account creation process. There is also information in the Quickstart +document that is shipped along with the EK-TM4C1294XL evaluation kit. + +This application uses a command-line based interface through a virtual COM +port on UART 0, with the settings 115,200-8-N-1. This application also +requires a wired Ethernet connection with internet access to perform +cloud-connected activities. + +Once the application is running you should be able to see program output +over the virtual COM port, and interact with the command-line. The command +line will allow you to see the information being sent to and from Exosite's +servers, change the state of LEDs, and play a game of tic-tac-toe. If you +have internet connectivity issues, need to find your MAC address, or need +to re-activate your EK-TM4C1294XL board with Exosite, the command line +interface also has options to support these operations. Type +'help' at the command prompt to see a list of available commands. + +If your local internet connection requires the use of a proxy server, you +will need to enter a command over the virtual COM port terminal before the +device will be able to connect to Exosite. When prompted by the +application, type 'setproxy help' for information on how to configure the +proxy. Alternatively, you may uncomment the define statements below for +"CUSTOM_PROXY" settings, fill in the correct information for your local +http proxy server, and recompile this example.
