### Description |
||||
Driver for the INA228 power monitor. |
||||
|
||||
Multiple instances of this driver can run simultaneously, if each instance has a separate bus OR I2C address. |
||||
|
||||
For example, one instance can run on Bus 2, address 0x45, and one can run on Bus 2, address 0x45. |
||||
|
||||
If the INA228 module is not powered, then by default, initialization of the driver will fail. To change this, use |
||||
the -f flag. If this flag is set, then if initialization fails, the driver will keep trying to initialize again |
||||
every 0.5 seconds. With this flag set, you can plug in a battery after the driver starts, and it will work. Without |
||||
this flag set, the battery must be plugged in before starting the driver. |
