Read a Calibrated Measurement

This example shows a typical workflow for reading a calibration file and using a translation table to calibrate a measurement reading.

Read the engine management ECU calibration file.

a2lobj = xcpA2L('ems.a2l');

Connect to the ECU.

ch = xcpChannel(a2lobj,'UDP','192.168.1.55',5555);

Set the table that translates a pedal position to a torque demand.

writeCharacteric(ch,'tq_accel_request', ...
[0 2 4 9 14 24 48 72 96 144 192 204 216 228 240]);

Set the pedal position to 50%.

writeMeasurement(ch,'pedal_position',50);

Read the demand.

value = readMeasurement(ch,'tq_demand')

value =
    96
