  34. * The following #include imports a "template appliance" definition. This app
  35. * comes with multiple implementations of the template appliance, each in a
  36. * separate directory, which allow the code to run unchanged on different
  37. * hardware.
  38. *
  39. * By default, this app targets hardware that follows the MT3620-mini Reference
  40. * Development Board (MDB) specification, such as the MT3620-mini Dev Kit from
  41. * Seeed Studio.
  42. *
  43. * To target different hardware, you'll need to update CMakeLists.txt.
  44. * For example, to target the Avnet MT3620 Starter Kit, make this update:
  45. * azsphere_target_hardware_definition(${PROJECT_NAME}
  46. * TARGET_DIRECTORY "HardwareDefinitions/avnet_mt3620_sk"
  47. * TARGET_DEFINITION "template_appliance.json")
