[Ovmsdev] Custom metrics

[Michael Balzer]

Tamás,

I've been creating separate metrics for all cell values on the Twizy, but that only has 14 cells.

We discussed this before, a better approach is introducing a new metric class for arrays. I have just done that for you, please pull.

Usage example:

    OvmsMetricVector<float>* vf = new OvmsMetricVector<float>("test.volts", SM_STALE_MIN, Volts);
    vf->SetElemValue(3, 1.23);
    vf->SetElemValue(17, 2.34);
    float myvals[3] = { 5.5, 6.6, 7.7 };
    vf->SetElemValues(10, 3, myvals);

With this data set, you get:

    OVMS# met lis test
    test.volts                               0,0,0,1.23,0,0,0,0,0,0,5.5,6.6,7.7,0,0,0,0,2.34V

…and in the web framework:

    metrics["test.volts"]
    (18) [0, 0, 0, 1.23, 0, 0, 0, 0, 0, 0, 5.5, 6.6, 7.7, 0, 0, 0, 0, 2.34]
    metrics["test.volts"][11]
    6.6

See template definition in ovms_metrics.h for more.

Regards,
Michael
