- Parameters
-
raw_sample | - The raw sample of the Current Readback from the ADC. |
current_ua | - The pointer through which the converted microamper value is returned. |
- Returns

) |
| |
- In the write command byte operation, the master device sends a command byte to the slave device.
- Parameters
-
device | - The device structure. |
cmd | - The command byte indicates which operation to be performed. |
reg_address | - In case of a write extended command byte operation one of the ADM1177_REG_ALERT_EN, ADM1177_REG_ALERT_TH or ADM1177_REG_CONTROL will be used. In case of a write command byte operation reg_address will be set to 0. |
