Reset button
This button performs a soft-reset of the Core with which the user is currently interacting.
User button
The functionality of this button is dependent upon both the Lumorphix boot state, and the loaded variant of Lumorphix Beta Release - specifically the number of Cores it contains. Irrespective of the number of Cores, the User button can be used to perform the following actions during boot / power-on:
User Button Actions | Functionality |
|---|---|
| Places the Tang Nano into ‘Firmware Update’ mode. |
| Resets the Lumorphix Flash region (i.e. uploaded programs, boot I/O state etc). |
Once Lumorphix has booted, the functionality of the User Button can be summarized as such (Beta Release / Number of Cores dependent):
Cores | User Button Functionality |

1 | When configured as an input (i.e. GPIO IN), PIN1 will have the value of Digital I/O1 OR’d with the User Button. |
