| 10 | ----------- | |
| 11 | ||
| 12 | Lochnagar 2 features built-in Current Monitor circuitry that allows for the | |
| 13 | measurement of both voltage and current on up to eight of the supply voltage | |
| 14 | rails provided to the minicards. The Current Monitor does not require any | |
| 15 | hardware modifications or external circuitry to operate. | |
| 16 | ||
| 17 | The current and voltage measurements are obtained through the standard register | |
| 18 | map interface to the Lochnagar board controller, and can therefore be monitored | |
| 19 | by software. | |
