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