# About
|
|
This is a manual test application for the INA3221 current and power
|
|
monitor driver.
|
|
|
|
# Usage
|
|
This test application will initialize the sensor with the following parameters:
|
|
- INA3221_PARAM_I2C: I2C_DEV(0)
|
|
- INA3221_PARAM_ADDR: INA3221_ADDR_00
|
|
- INA3221_PARAM_PIN_WRN: GPIO_UNDEF, or given WRN input pin
|
|
- INA3221_PARAM_PIN_CRT: GPIO_UNDEF, or given CRT input pin
|
|
- INA3221_PARAM_PIN_TC: GPIO_UNDEF, or given TC input pin
|
|
- INA3221_PARAM_PIN_PV: GPIO_UNDEF, or given PV input pin
|
|
- INA3221_PARAM_CONFIG: (
|
|
INA3221_ENABLE_CH1 | INA3221_ENABLE_CH2 | INA3221_ENABLE_CH3,
|
|
INA3221_NUM_SAMPLES_4 |
|
|
INA3221_CONV_TIME_BADC_4156US |
|
|
INA3221_CONV_TIME_SADC_4156US |
|
|
INA3221_MODE_CONTINUOUS_SHUNT_BUS
|
|
)
|
|
- INA3221_PARAM_RSHUNT_MOHM_CH1: 100
|
|
- INA3221_PARAM_RSHUNT_MOHM_CH2: 100
|
|
- INA3221_PARAM_RSHUNT_MOHM_CH3: 100
|
|
|
|
After initialization, the application will perform basic read/write
|
|
functionality tests. If the preceding static tests succeed, the program
|
|
will enter an endless loop and check if a full conversion cycle has
|
|
completed. If new values for shunt voltage and bus voltage are available,
|
|
current and power are calculated and each value for every channel is
|
|
printed to stdio in a neat table, with available status flags.
