Example

--Note: The calibration and algorithm are adjusted according to their own design.
--Note: due to the use of sys.wait() all apis need to be used in the coroutine
-- Usage Examples
local ina226 = require "ina226"

local i2cid = 0
sys.taskInit(function()
    i2c.setup(i2cid, i2c.FAST)
    ina226.init(i2cid)
    while 1 do
        local ina226_data = ina226.get_data()
        log.info("ina226_data", "shunt_voltage",ina226_data.shunt_voltage,"bus_voltage",ina226_data.bus_voltage,"power",ina226_data.power,"current",ina226_data.current)
        sys.wait(1000)
    end
end)

ina226.init(ina226_i2c, conf, cal)
