/*
 * The following #include imports a "template appliance" definition. This app
 * comes with multiple implementations of the template appliance, each in a
 * separate directory, which allow the code to run unchanged on different
 * hardware.
 *
 * By default, this app targets hardware that follows the MT3620-mini Reference
 * Development Board (MDB) specification, such as the MT3620-mini Dev Kit from
 * Seeed Studio.
 *
 * To target different hardware, you'll need to update CMakeLists.txt.
 * For example, to target the Avnet MT3620 Starter Kit, make this update:
 *      azsphere_target_hardware_definition(${PROJECT_NAME}
 *      TARGET_DIRECTORY "HardwareDefinitions/avnet_mt3620_sk"
 *      TARGET_DEFINITION "template_appliance.json")
 *
 * See https://aka.ms/AzureSphereHardwareDefinitions for more details.
