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.
